In this case study, we describe a 46-year-old male presenting with a palpable, gradually enlarging scrotal mass persisting over three to four years, ultimately diagnosed as paratesticular leiomyoma, who underwent enucleation of the tumor with no signs of recurrence, two years after surgery. This report underscores the significance of accurate diagnosis to avoid unnecessary treatment. We also emphasize the sequential events and findings, supported by relevant literature review, that contributed to establishing the correct diagnosis and guiding appropriate treatment decisions., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Myxoid pleomorphic liposarcoma (MPLPS) is an extremely rare entity that has been recognized and included in the literature recently. Liposarcomas are adipocytic tumors that are usually located in the extremities and retroperitoneum. Paratesticular liposarcomas are extremely rare malignant tumors originating from the adipose tissue of the paratesticular region. Myxoid pleomorphic liposarcoma (MPLPS) is an exceedingly rare variant of liposarcoma, with very few cases reported in the literature so far. Mediastinum is the most common site for MPLPS followed by the limbs, head, and neck. We report a case of a 50-year-old male patient who presented with a swelling in the right inguinal region, which came to the patient's attention in the past month. After investigations, a right-high orchidectomy was done. Histopathological examination and immunohistochemistry were performed and a diagnosis of myxoid pleomorphic liposarcoma (MPLPS) involving the spermatic cord was made. So here we report this case of myxoid pleomorphic liposarcoma involving the spermatic cord for the first time in the literature., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Rare tumors of the testis not originating from germinal epithelium are a diagnostic and therapeutic challenge., Objectives: To present current approaches in rare tumors of the testis using the examples of Sertoli cell tumor (SCT) and malignant mesothelioma of the tunica vaginal testis (MMTVT)., Methods: A literature search in PubMed and the abstract databases of ASCO and ESMO was performed. Articles and book chapters were selected based on relevance to everyday treatment., Results: The low incidence of testicular tumors not originating from the germinal epithelium makes a standardized approach difficult. Diagnosis and treatment depend on the underlying diagnosis. While most SCT are benign, malignant subtypes require extensive resection including metastatic surgery if complete resection is possible. In MMTVT, multimodality treatment concepts are followed, according to the malignant mesotheliomas of the pleura., Conclusion: Systematic registration of rare testicular tumors and comprehensive molecular pathological analysis are urgently needed to improve the understanding of tumor biology and to develop new therapeutic strategies., (© 2021.
