The article in the Clinical & Experimental Dermatology journal reports on a case of Poikiloderma vasculare atrophicans (PVA), a rare variant of early-stage mycosis fungoides (MF), in a 70-year-old woman with a 35-year history of the condition. The patient presented with asymptomatic, erythematous-to-purplish scaly macules and hyperkeratotic papules, with histological and immunohistochemical studies confirming the diagnosis of PVA. Despite various treatment options being offered, the patient declined interventions, and there has been no progression of the pathology observed. The article highlights the challenges in diagnosing PVA and the ongoing debate about its classification within the spectrum of cutaneous T-cell lymphomas. [Extracted from the article]

Simple Summary: Although the potential role of imaging-based parameters or pathological factors as useful cancer biomarkers has been reported in several studies, only a few investigations have been conducted to assess the associations between them. We hypothesized that the imaging features of OSCC, derived from perfusion- and diffusion-weighted techniques, may reflect not only the characteristics of cancer but also the microenvironment composition. We found that a number of pathological factors affected the imaging parameters, i.e., the inflammatory infiltrate, tumor grading and desmoplastic reaction. Evident relationships emerged between the DKI parameters and tumor-infiltrating lymphocytes. Significant differences in a few DCE-MRI parameters were also found according to the tumor grading. These findings may be helpful for a more comprehensive biological characterization of OSCC and could be used in future investigations for diagnostic and prognostic purposes. Background: In this prospective study, we hypothesized that magnetic resonance imaging (MRI) may represent not only the tumor but also the microenvironment, reflecting the heterogeneity and microstructural complexity of neoplasms. We investigated the correlation between both diffusion kurtosis imaging (DKI) and dynamic contrast-enhanced (DCE)-MRI with the pathological factors in oral cavity squamous cell carcinomas (OSCCs). Methods: A total of 37 patients with newly diagnosed OSCCs underwent an MR examination on a 3T system. The diffusion coefficient (D), the kurtosis parameter (K), the transfer constants Ktrans and Kep and the volume of extravascular extracellular space ve were quantified. A histogram-based approach was proposed to investigate the associations between the imaging and the pathological factors based on the histology and immunochemistry. Results: Significant differences in the DCE-MRI and DKI parameters were found in relation to the inflammatory infiltrate, tumor grading, keratinization and desmoplastic reaction. Relevant relationships emerged between tumor-infiltrating lymphocytes (TILs) and DKI, with lower D and higher K values being associated with increased TILs. Conclusion: Although a further investigation is needed, these findings provide a more comprehensive biological characterization of OSCCs and may contribute to a better understanding of DKI-derived parameters, whose biophysical meaning is still not well-defined.

Background: Undifferentiated soft-tissue sarcomas (USTS) are one of the most common sarcoma histotypes in adults. The standard of care is surgical excision plus adjuvant radiotherapy, while the use of perioperative chemotherapy is still controversial. The aim of this study was to investigate the value of pre-treatment [18F]FDG PET/CT conventional metrics and textural features in predicting disease-free survival (DFS) and overall survival (OS) in patients with USTS of the limbs and trunk. Methods: [18F]FDG PET/CT scans of 51 consecutive patients with locally advanced USTS were retrospectively evaluated. Conventional and textural PET parameters were analysed and tested as predictive factors for DFS and OS. Results: During a median follow up of 50.7 months, 23 (45.1%) and 29 (56.9%) patients had death or disease progression, respectively. Univariate analysis revealed a significant association for perioperative treatment, PET volumetric parameters and the textural feature GLCM_correlation with DFS and OS. In multivariate analysis, perioperative treatment and GLCM_correlation were the only independent factors, allowing stratification of the population into three different prognostic classes. Conclusion: GLCM_correlation can identify USTS at high risk of relapse and death, thus helping to optimize the perioperative treatment of patients. [ABSTRACT FROM AUTHOR]

Background: Acute myocarditis (AM) is an inflammatory heart disease that may occur as a consequence of autoimmune disorders. Although the correlation between myocarditis and hyperthyroidism has been reported in the literature, the association with hypothyroidism is less frequent., Case Summary: We describe a characteristic case of lymphocytic acute myocarditis deteriorated into cardiogenic shock due to Hashimoto's thyroiditis treated with vasopressor and inotropic drugs in combination with corticosteroid. On admission, electrocardiography revealed a sinus tachycardia with 1st degree atrioventricular (AV) block, right bundle branch block (RBBB), and left anterior fascicular block. Laboratory tests demonstrated a severe hypothyroidism and high-titre serum of antibodies against thyroglobulin. She presented a favourable clinical course, restoring haemodynamic stability. A resolution of hypothyroidism and a progressive reduction of the value of antibodies against thyroglobulin occurred. On Day 35, the patient was discharged showing on electrocardiogram the occurrence of left posterior fascicular block, disappearance of 1st degree AV block and partial improvement of RBBB along with the normalization of the left ventricular contractility abnormalities on echocardiography., Discussion: Autoimmune features, mostly Hashimoto's thyroiditis, are associated in lymphocytic acute myocarditis to a worse prognosis and an increased risk of recurrence. More studies are needed to elucidate the underlying mechanism., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2024.

Vasculitides are diseases that can affect any vessel. When cardiac or aortic involvement is present, the prognosis can worsen significantly. Pathological assessment often plays a key role in reaching a definite diagnosis of cardiac or aortic vasculitis, particularly when the clinical evidence of a systemic inflammatory disease is missing. The following review will focus on the main histopathological findings of cardiac and aortic vasculitides., (Copyright © 2024 Società Italiana di Anatomia Patologica e Citopatologia Diagnostica, Divisione Italiana della International Academy of Pathology.)

Introduction: Adrenocortical Carcinoma (ACC) is an uncommon adrenal tumor with a predilection for the female population., Case Report: A 55-year-old woman was referred to our attention to undergo laparoscopic cholecystectomy for symptomatic gallstone disease. She underwent a left adrenalectomy for ACC 5 years before; the follow-up was negative for relapse. During the preoperative study an Ultrasound Scanner study demonstrated a liver lesion in S6 - S7, confirmed by a Magnetic Resonance. A PET identified also a lesion on L1 vertebra. The hepatic US-guided biopsy resulted positive for ACC metastasis. After a muldisciplinary evaluation, the patients underwent a local approach to treat both hepatic and vertebral lesions. Laparoscopic cholecystectomy was performed in order to prevent biliary and pancreatic complications. The minimally invasive technique was adopted in order to reduce surgical trauma in oncological patients, even the previous abdominal surgery and percutaneous hepatic treatment. The patient is alive, with no recurrence after 12 months from local treatments., Conclusion: This is a very unusual case of double ACC metastases, discovered after the end of standard follow-up and locally treated. The patient is recurrence-free 12 months after these procedures. Minimally invasive approach to treat symptomatic cholecystectomy was used in order to avoid pancreato-biliary complications. This study emphasized the necessity to realize tailored protocols for the follow-up of rare neoplasia, as ACC., Key Words: Adrenocortical carcinoma, Cholecystectomy, Liver metastasis, Thermoablation.
