Rationale: Primary seminal vesicle adenocarcinoma is a rare type of male reproductive system tumor, primarily manifesting as papillary adenocarcinoma. Meanwhile, clear cell adenocarcinoma (CCA) is a common malignancy in the female reproductive system. Therefore, the occurrence of CCA in the seminal vesicle, showing ovarian homology, is even rarer. This pathological type of seminal vesicle cancer has been seldom reported., Patient Concerns: A 43-year-old male patient presented to the outpatient clinic with a decade-long history of intermittent hemospermia accompanied by a 2-month sensation of dragging in the left lower abdomen. Following an MRI scan that indicated a seminal vesicle mass, he was admitted for further treatment., Diagnosis: The MRI revealed 2 abnormal signal mass lesions located between the left side of the pelvic cavity, the prostate, and the left seminal vesicle, primarily exhibiting long T1 and long T2 cystic characteristics. The CT scan with enhancement showed mixed density mass shadows in the left seminal vesicle area of the pelvic cavity, with mild arterial phase enhancement and continued enhancement in the portal phase. Physical examination revealed mild tenderness in the lower left abdomen. Digital rectal examination detected a hard mass above the left prostate, with no bloodstain on the glove, and no other significant abnormalities were observed. Routine urinalysis and biochemistry did not reveal any notable abnormalities. Tumor markers were all within normal ranges., Interventions: The tumor was completely excised laparoscopically and sent for pathological examination. Nine days postoperatively, the patient was successfully discharged., Outcomes: Postoperative pathology indicated primary CCA of the seminal vesicle. During a 20-month follow-up via telephone, the patient reported a generally good condition without significant discomfort., Lessons: CCA occurring in the seminal vesicle is extremely rare, and radical surgical excision is the primary treatment method., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Scrotal masses, whether cystic or solid lesions, are routinely evaluated using ultrasonography. Magnetic resonance imaging (MRI) may be used for further investigation in cases with atypical findings, difficult diagnoses, large masses, and/or unclear relationships with the surrounding tissues. Scrotal solid masses are divided into intra- and extra-testicular masses. A staggering 90% of the intratesticular masses are malignant, whereas 75% of extratesticular masses are benign. Extratesticular masses are less common than intratesticular masses; however, some extratesticular masses present characteristic MRI findings. Familiarity with these specific MRI features of extratesticular masses is beneficial to radiologists, as appropriate diagnoses can help avoid unnecessary invasive treatments such as orchiectomy. In this review, we describe fibrous pseudotumors, polyorchidism, adenomatoid tumors, and scrotal leiomyoma as benign paratesticular masses, focusing on their characteristic imaging features on MRI. Although these tumors are extremely rare, their MRI findings are distinctive, and accurate diagnoses can prevent unnecessary orchiectomy. In addition, to demonstrate the pitfalls of diagnosing extratesticular masses, we present a case of seminoma misidentified as extratesticular masses due to large extensions outside the testis. Spermatic cord sarcoma, including rhabdomyosarcoma, leiomyosarcoma, and liposarcoma, and metastasis to the spermatic cord are described as malignant extratesticular masses. This review focused on extratesticular masses and elaborates the imaging findings that can aid in the accurate diagnosis using MRI., (© 2024. The Author(s).)

Seminal vesicles play a crucial role in the male reproductive system, as they are responsible for secreting a fluid that forms most of the ejaculate. Seminal vesicles' pathology can present with non-specific symptoms, making imaging diagnosis essential for proper patient management. Various imaging modalities can be used to evaluate these glands, with MRI beneficial in illustrating the spectrum of seminal vesicle disease. Typical seminal vesicles appear as elongated fluid-containing structures, but congenital anomalies, inflammatory conditions, and neoplastic disorders can alter their appearance. Furthermore, differentiating mimics from actual pathology can be challenging but crucial for proper management. This article aims to provide an overview of the typical imaging appearance of the seminal vesicles and illustrate the principal imaging characteristics of conditions involving these structures. It will review the imaging characteristics of common and uncommon lesions involving the seminal vesicles by exploring congenital, infectious, and neoplastic in detail. As the seminal vesicles are often evaluated incidentally during prostate imaging, radiologists should be aware of the variability of normal findings and recognize the principal pathologies affecting these structures to ensure proper patient management., Competing Interests: Declaration of competing interest None, (Copyright © 2024.

Spermatic cord malignancies are a scarce modality and liposarcoma of spermatic cord is even a rarer condition encountered. Liposarcoma is usually a slowly progressive, non-tender, well circumscribed mass of variable shapes owing to conformity to fascial compartments. We are reporting a case of 65-year-old male, with a two-month history of initially tender and later non-tender mass in the scrotum, above the testis. Ultrasonography showed a right mid inguinal mass measuring 6x3x3 cm at the superior pole of the right testis and small fluid around the right testis. Fine needle aspiration cytology (FNAC) of the right inguinal mass revealed a spindle cell neoplasm. The patient underwent right inguinal radical orchiectomy with local wide excision of the sarcoma of the spermatic cord origin. Final histopathology confirmed dedifferentiated liposarcoma. No adjuvant treatment was offered and the patient was put on surveillance. Follow-up of more than 10 months has not revealed any local recurrence, regional or non-regional lymph nodes, or systemic metastasis.

Background: Leiomyosarcoma is a tumor that can develop in any organ that contains smooth muscles. Although leiomyosarcoma is common, its epididymal localization is quite rare., Case Presentation: A 79-year-old male Chinese Han patient presented with mild pain in the right groin and scrotum for 3 years concomitant with right scrotal swelling. Ultrasonography and magnetic resonance imaging of the scrotum showed a irregular and heterogeneous mass that was extratesticular. Right high orchiectomy was performed, and pathological examination of the resected specimen confirmed the diagnosis of leiomyosarcoma of the epididymis with surgical margins clear of tumor., Conclusion: Epididymal leiomyosarcoma is rare and difficult to diagnose preoperatively. The final diagnosis of epididymal leiomyosarcoma requires histologic examination. Resection must be extensive and complete. The effect of chemotherapy and radiation on the epididymal leiomyosarcoma remains unclear. Recurrence is common, so follow-up is necessary., (© 2024. The Author(s).)

A 63-year-old man presented with right scrotal swelling. A physical examination revealed a painless, palpable mass in the right scrotum. The mass was well defined and lobulated. Subsequently, a diagnosis of right epididymal tumor was made, and right high orchiectomy was performed. Hematoxylin-eosin and immunostaining revealed leiomyosarcoma of the epididymis. When a diagnosis of epididymal malignant tumor is made, the standard treatment is radical orchiectomy.

We present the case of a 73-year-old male patient who presented with obstructive urinary symptoms, pelvic pressure, and hematuria. CT imaging revealed a heterogenous prostate enlargement, and MRI demonstrated the mass to be arising from the seminal vesicle. Prostate biopsies showed benign tissue. Surgical excision was completed and pathology revealed it to be an epithelioid smooth muscle neoplasm of uncertain biologic potential. This is only the second known case of such a seminal vesicle tumour. As soft tissue sarcomas of the seminal vesicle emerge in the literature, we may develop a better understanding of their biologic behaviour and prognostic potential.

Scrotal lymphangiomas represent an extremely rare cause of scrotal swelling. We report a case of scrotal lymphangioma in an 18-year-old male who presented with painful scrotal swelling. Scrotal ultrasound revealed a complex multicystic structure in the left hemiscrotum. The patient underwent successful surgical excision of the mass. Postoperatively, he developed a hydrocele which eventually spontaneously regressed. Histopathology confirmed the diagnosis. We outline the unusual presentation, characteristic imaging and histology findings, and surgical management of scrotal lymphangiomas. With this information, urologists may exercise a heightened level of awareness for this rare cause of scrotal swelling.

Background: Aggressive angiomyxoma (AAM) is a locally infiltrative mesenchymal tumour that most commonly affects the pelvis and/or perineum in adult women. AAM is very rare in males, especially in infancy., Case Presentation: A 10-month-old fulani (African) male infant was referred to our department for a large painless mass in the right testicule. The mass was detected during the neonatal period and gradually increased in size. Ultrasound examination revealed a large heterogeneous lesion; computed tomography results led to the conclusion that the mass was a mesenteric hernia. An inguinal and scrotal surgical approach was adopted. Exploratory surgery found a normal right testicle displaced upwardly and a large scrotal mass. Radical excision of the mass and orchidopexy were performed. Subsequent histology and immunohistochemstry studies indicated that the mass was a scrotal angiomyxoma. The postoperative course was uneventful. No recurrence occurred during the 6-month follow-up., Conclusion: To the best of our knowledge, this is the youngest patient with AAM reported to date. Angiomyxoma should be included in the differential diagnosis of scrotal masses, for which radical excision is justifiable to prevent recurrence., (© 2022. The Author(s).)

Rationale: Schwannoma is common in young and middle-aged people and occurs in the head, neck, posterior mediastinum, and retroperitoneal. Schwannoma, on the other hand, is a rare occurrence in the seminal vesicle. Early diagnosis and treatment are crucial since the disease can cause lower abdominal pain, nocturia, frequent urination, blood sperm, and other symptoms. There is no standard diagnostic or treatment guideline for seminal vesicle schwannomas currently. Therefore, the treatment experience relies on the few cases reported throughout the world., Patient Concerns: A 45-year-old male patient discovered that the tumor beside the right side spermatophore is bigger than 3 years ago., Diagnosis: Schwannoma of seminal vesicle., Interventions: Ureter double-J tube implantation and laparoscopic surgery for schwannoma of seminal vesicle., Outcomes: The operation process went smoothly. And the patient was no discomfort after half a year., Conclusion: Schwannoma of the seminal vesicle is very rare in the clinic, and the imaging examination was not conclusive. The diagnosis mainly depends on pathological results. Surgical resection is the best treatment method for schwannoma. In surgery for schwannoma of seminal vesicle, combined with the ureter double-J tube implantation are many benefits. This case is an excellent example of the seminal vesicle schwannomas., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

A 52-year-old man was referred to our hospital for evaluation of painless right scrotal swelling persisting for 3 months. Palpation detected swelling and induration centered on the head of the upper epididymis, and ultrasonography revealed a blood-filled nodular mass at the same site continuing to the spermatic cord. No abnormalities were observed in the bilateral testes. Blood tests were negative for tumor markers such as α fetoprotein and human chorionic gonadotropin-β. Right radical inguinal orchiectomy was performed, and the pathological diagnosis was dedifferentiated liposarcoma of the spermatic cord. Although the spermatic cord stump was negative, the peri-spermatic cord stump, which had an exfoliated surface, was positive. No residual tumor was found on magnetic resonance imaging, but the tumor was suspected to remain. Thus, after approximately 1month, the tissue around the spermatic cord was resected. Eight months after the initial operation, no recurrence was observed. Here, we report a case of dedifferentiated liposarcoma of the spermatic cord, which is relatively rare, and review the related literature.

A 66-year-old man came to our department with the chief complaint of a right inguinal painless mass. He was diagnosed with a right spermatic cord tumor and underwent a right high orchiectomy with wide excision. The results of hematoxylin eosin staining and immunostaining procedures showed mucosa-associated lymphoid tissue (MALT) lymphoma originating from the lymphoid tissue of spermatic cord. The patient was referred to the department of hematology at another hospital for treatment. As results of additional immunostaining procedures at that hospital, the pathological diagnosis was diffuse large B-cell lymphoma (DLBCL). The positron emission tomography-computed tomography revealed no residual tumor or metastasis, and the final diagnosis was primary DLBCL Stage I of the spermatic cord. The patient was treated with 6 courses of R-THP-COP, 2 courses of Rituximab, and 3 courses of intrathecal chemotherapy, including Methotrexate, Ara-C, and Prednisolone. In addition, prophylactic radiation therapy to another testis was planned. Primary DLBCL of the spermatic cord is rare, and the standard treatment is the same as that for testicular DLBCL.

Background: Up to 30% of all scrotal masses are sarcomas. Leiomyosarcoma of the scrotal wall is rare, and its clinical significance and prognosis have not been well defined, since the most reported cases have little or no follow-up., Case Presentation: We report a 45-year-old Caucasian man who was admitted with a firm, nontender, mobile scrotal wall mass from 15 months ago. Laboratory data including testicular tumor markers were within normal range, and transscrotal ultrasonography revealed an oval-shaped, hypoechogenic, solid mass with blood flow and well-defined border. Histopathologic examination and immunohistochemistry staining, following surgical excision, were in favor of malignant leiomyosarcoma., Conclusion: Here we describe the morphological features and immunohistochemical presentations of the tumor and the patient's relatively long-term follow-up., (© 2021.

Liposarcoma of the spermatic cord is a malignant tumor so rare that there are less than 200 cases reported in the literature worldwide. Liposarcoma is a malignancy which originates from fat tissue. Although only 3%-7% of all paratesticular sarcomas primarily arise from structures of the spermatic cord, clinical significance of these tumors must not be neglected because they are often preoperatively misdiagnosed. A 66-year-old male presented with a painless swelling on the left side of the scrotum. Local examination revealed a solid, smooth, limited mass of approximately 4x3 cm in the left side of the scrotum. Tumor markers were within the reference range. Ultrasound examination showed a solid, clearly limited non-homogeneous mass of 40x20 mm localized in the left spermatic cord. Magnetic resonance imaging showed an expansive mass measuring 60x85x60 mm in the left inguinoscrotal region without propagation into the abdominal cavity. Both testicles and epididymides appeared normal on magnetic resonance examination and no locoregional enlarged lymph nodes were seen. The patient was treated operatively with radical inguinal orchiectomy. In conclusion, liposarcomas of the spermatic cord are extremely rare neoplasms that clinically present as slow-growing, painless, palpable inguinal or scrotal masses. Radical orchiectomy with high ligation of the spermatic cord and wide excision of the surrounding soft tissues within the inguinal canal remains the gold standard treatment option. Recurrence of the disease is frequent even several years after primary therapy, therefore long-term follow-up is mandatory.

Mixed epithelial-stromal tumours (MESTs) of the seminal vesicle (SV) are a rare neoplasm, with biological behaviour ranging from benign to malignant. Due to their rarity, there are no established guidelines for their treatment. We report a 37-year-old man with a large MEST of the SV which was successfully resected by laparoscopic transperitoneal approach. Amidst the controversy regarding the nomenclature and grading of MESTs in literature, we reclassified the previous reports of MESTs incorporating both the WHO and Reikie et al grading., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Metastasis to the scrotal sac is a very rare phenomenon. We present a case of a 45-year-old man diagnosed with locally advanced acinar adenocarcinoma prostate, post bilateral orchidectomy and radiotherapy treatment, who showed a rising trend of serum PSA levels with discovery of scrotal sac metastasis on serial Ga-prostate-specific membrane antigen PET/CT scans.

Rationale: Schwannoma is a benign peripheral nerve sheath tumor composed of Schwann cells and caused by genetic mutation or deletion. It rarely occurs in seminal vesicles. The optimal therapic strategy for asymptomatic cases is still unclear., Patient Concerns: A 42-year-old man presented no clinical symptoms. A mass in his left seminal vesicle was found incidentally in a computed tomography scan and transrectal ultrasound-guided biopsy revealed the mass was schwannoma., Diagnosis: The patient was diagnosed as schwannoma of the seminal vesicle with no significant extension to the surrounding tissues., Interventions: The patient underwent computed tomography or magnetic resonance imaging scans periodically to estimate the alteration of the lesion and further strategy., Outcomes: After 20-month follow-up, computed tomography scans showed no significant alteration to the lesion and no clinical symptoms were reported by the patient., Lessons: Conservative strategy might be an effective treatment option for asymptomatic patients with seminal vesical schwannoma. The period of follow-up depends on the size of the tumor.

Rationale: Schwannomas of the seminal vesicles are extremely rare, and only cases of single seminal vesicle schwannomas have been reported. Here, we report a case of multiple schwannoma of the seminal vesicle., Patient Concerns: We report a rare case of multiple schwannoma of the seminal vesicle that occurred in a 48-year-old man during physical examination. Multiple mixed masses in the left region of the seminal vesicle were documented with transrectal ultrasonography and magnetic resonance imaging. The patient presented no clinical symptoms, no family history of the disease and no history of genetic disease., Diagnosis: Postoperative pathology revealed a diagnosis of seminal vesical schwannoma., Interventions: The patient underwent robotic-assisted laparoscopic surgery to remove the mass., Outcomes: The patient recovered rapidly and the length of hospitalization was 6 days after operation. At present, there is no recurrence in 10 month follow up., Lessons: Whether benign or malignant, single or multiple, schwannomas still need to be diagnosed by pathology because of the limitations of examination methods. Surgical resection is still the preferred treatment.

Extramammary Paget disease (EMPD) is a rare intraepithelial malignancy originating in areas rich in apocrine glands, such as the vulva, perineum, perianal area, scrotum, and penis. A few reports of EMPD involving the scrotum have been described in the literature. However, only few reports have described imaging features observed in patients presenting with EMPD. We report EMPD in a patient showing scrotal involvement, focusing on imaging features, particularly those determined ultrasonographically.

Background: Solitary fibrous tumor (SFT) is a rare soft tissue tumor originally reported in the pleura. Although it has been reported in various extra-pleural sites, the occurrence of SFT in the scrotum is extremely rare. Herein, we present a 48-year-old man who had scrotal SFT. There are very few reported cases of genitourinary SFTs, this is only the fifth report of SFT of the scrotum in the English medical literature., Case Presentation: In this study, we report on a 48-year-old man who presented with a 5 × 8 cm scrotal mass between his testes. Physical examination revealed a 4.7 × 8.5 cm lobulated tumor mass located between his testicles. Surgical excision of the tumor with scrotal approach was done and pathology reported a SFT. The patient was alive without tumor recurrence or distant metastasis during ongoing follow-up for 9 months post-operatively.., Conclusion: Scrotal SFTs are very rare and only five cases have been reported in English literature to date. Treatment often involves surgical resection, and a definite diagnosis is made with the help of immunohistochemistry. The current general consensus for the management of SFTs is long-term follow-up after surgical excision of the tumor.

The rarity of primary seminal vesical adenocarcinoma (PSVA) coupled with mostly late and advanced presentation with high mortality makes it an unanticipated malignancy with poor prognosis. Although there has been sporadic reporting of cases, the dearth of literature makes standardised care a challenge. The detection has incorporated immunohistochemistry for establishing the site of origin as well as the differentiation of primary from metastatic cancer. Surgical management with seminal vesiculectomy continues to be the mainstay of treatment, but difficult anatomy and delayed intervention do lead to an increased chance of residual disease that may warrant further adjuvant chemoradiation. We present a case report where PSVA developed in a patient with Zinner syndrome-an observation that is extremely rare with a literature review of PSVA including the various aspects of management including contemporary diagnosis techniques., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

We report the first known case of a metastatic thymic tumor arising from spermatic cord leiomyosarcoma, occurring in a 35-year-old man. He had undergone an orchiectomy 24 months previously and a surgical excision of a subcutaneous metastasis 4 months prior to his current presentation. Computed tomography revealed a 1.5-cm, round-shaped anterior mediastinal mass. A thymectomy was performed and the diagnosis of metastatic leiomyosarcoma was made.

Rationale: Primary squamous cell carcinoma (SCC) of the seminal vesicle is extremely rare, and the clinical characteristics of this kind of malignancy are still unclear., Patient Concerns: A 62-year-old male patient presented with complaints of sensation of rectal tenesmus and dysuria., Diagnosis: Ultrasonography suggested a hypoechoic mass behind the bladder, meanwhile, computerized tomography (CT) and magnetic resonance imaging (MRI) revealed a 40 mm × 45 mm × 48 mm mixed solid/cystic tumorous lesion in the right seminal vesicle. Postoperative histology confirmed the diagnosis of primary SCC in the seminal vesicle., Intervention: The mass was surgically excised with a laparoscopic approach. Postoperatively, 6 cycles of chemotherapy and 50 Gy of external beam radiation were concurrently performed on this patient., Outcomes: No local recurrence or distant metastasis was detected within 2 years after the surgery., Lessons: Primary SCC of the seminal vesicle is a rare neoplasm with a poor prognosis. Clinically, it is crucial to establish early precise diagnosis and apply multimodality treatment.

We present a case of a patient with a large, symptomatic abdominal tumour, which finally could be classified as a leiomyoma arising from the right seminal duct/seminal vesicle. In computed tomography (CT) scan, it appeared as a 7.5 × 6.5 cm solid, supravesical mass. A cystoscopy as well as bilateral retrograde studies was normal, a transrectal ultrasound-guided biopsy and an ultrasound-guided transabdominal biopsy of the mass were inconclusive. Subsequently, we performed a tumour extirpation through a lower midline laparotomy. Histological examination showed a leiomyoma arising from the right seminal duct or seminal vesicle. In this article, we discuss clinical presentation, findings on imaging and management of this rare benign tumour and review the relevant literature where only 13 similar cases could be identified., (© 2018 Blackwell Verlag GmbH.)

Diagnosis of genital inflammatory disorders may be difficult for several reasons, such as their similar appearance, possible misdiagnosis with infectious and malignant conditions, and peculiar anatomic conditions that may lead to modification of clinical features. Dermoscopy could be included as a part of the clinical inspection of genital diseases to support diagnosis, as well as to ideally avoid unnecessary invasive investigation. Practical guidance for the use of dermoscopy in the assessment of the main inflammatory genital diseases is provided, namely for lichen sclerosus, lichen planus, psoriasis, lichen simplex chronicus, and plasma cell mucositis., (Copyright © 2018 Elsevier Inc.

Herein we report a case of Kimura's disease with unusual manifestations. A 46-year- old Chinese man presented with mass in scrotum which gradually increased in size for approximately 7 years. A computerized tomographic scan of abdomen revealed a soft-tissue density shadow in scrotum and enlargement of lymph nodes in groin and retroperitoneum. The scrotal mass was excised and the biopsy specimen revealed angiolymphoid hyperplasia with infiltration of eosinophils. In conclusion, clinical doctors should pay attention that the patient with eosinophilia and scrotal mass could be indicative for Kimura's disease.

Primary extranodal lymphomatous involvement of the genitourinary tract is rare and secondary extranodal involvement in disseminated disease occurs more frequently. Imaging of metabolic activity with 2-(fluorine-18) fluoro-2-deoxy-d-glucose (FDG) used in PET facilitates the identification of these extranodal sites of disease, particularly in the absence of structural lesions on conventional imaging modalities. Primary extranodal lymphoma affecting the genitourinary system is often caused by high-grade Non-Hodgkin's Lymphoma (NHL) with the most common subtype being diffuse large B-cell lymphoma (DLBCL). Although rare, the incidence of extranodal lymphoproliferative disease is increasing and a delay in diagnosis holds a poor prognosis. Familiarity with benign and physiological causes of FDG uptake, particularly due to the urinary tracer excretion is crucial in identifying sites of lymphomatous involvement in the genitourinary system. Additionally, non-lymphomatous malignancies are usually treated surgically, whereas lymphoma is primarily treated with chemotherapy and/or radiotherapy. Therefore, accurate identification and staging together with histological confirmation significantly impacts management of these patients. This article serves to review and illustrate the imaging findings on FDG-PET/CT of primary extranodal lymphoma affecting the genitourinary system.

Introduction: Metastatic epididymal and spermatic cord adenocarcinoma from epithelial tumors are a rare condition. The most frequent primary cancers are prostate, lung, kidney, gastrointestinal tumors and breast. In literature, there are very low number of cases reporting metastasis from pancreatic cancer to epididymis and spermatic cord., Case Description: We report a case of 70-years old man with history of left orchiectomy for undescended testicle, who presented to our department with a palpable nodule in the right scrotum. Scrotal ultrasound revealed an inhomogeneous hypoechoic nodule of epididymis and/or spermatic cord. Neoplastic markers showed high levels of CEA (carcinoembryonic antigen) and bHCG (beta Human Chorionic Gonadotropin). The patient underwent right surgical scrotal exploration with orchifunicolectomy. Pathologic examination revealed pathologic tissue showing rare glandular structures. Immunohistochemistry profile was compatible with malign epithelial neoplasm with glandular differentiation. Total body CT-scan revealed pathologic tissue in pancreas between head and body and a suspect pathologic lesion in liver and 18-FDG PET-scan confirmed the pancreatic neoplastic mass and a suspect secondary hepatic lesion. Biopsy of pancreatic pathologic area was positive for ductal pancreatic adenocarcinoma. The patient was sent to oncologic evaluation and started chemotherapy., Conclusions: Malignancies of epididymis and spermatic cord are rare entities and, in literature, very low number of cases of metastasis from pancreatic carcinoma to epididymis and spermatic cord are described. Early differential diagnosis is fundamental mostly in those patients with age range unusual for testis cancers.

Liposarcoma of the spermatic cord is extremely rare in dogs and humans. This report describes the clinical signs, typical diagnostic imaging including ultrasound and computed tomography, and treatment of a liposarcoma of the spermatic cord of a Toy Poodle confirmed by histological examination after a surgical procedure. This case highlights the importance of preoperative diagnostic imaging and histopathological examination in dogs with an inguinal or scrotal mass.

A 63-year-old man was referred to our department because of painless hard mass in the right inguinal region. Abdominal computed tomography (CT) showed right spermatic cord mass measuring 25 mm in diameter. We performed right high orchiectomy. Histopathological diagnosis was dedifferentiated liposarcoma, which included myofibroblast components. He was alive 3 years postoperatively without recurrence.
