We describe cytogenetics of a case of nodular hyperplasia of the thyroid with papillary microcarcinoma following radiotherapy for Hodgkin's disease. The chromosomal pattern found was very heterogeneous with a clonal abnormality of chromosome 10, among others. Together with some recent data from the literature, this finding may point to an important role of chromosome 10 abnormalities in the pathogenesis of benign and malignant thyroid neoplasms.

Proliferations of neoplastic perivascular epithelioid cells (PECs) may occur within the lung and extrathoracic sites. The term "PEComatosis" is applied to multiple or diffuse microscopic proliferations of neoplastic PECs. Pulmonary diffuse PEComatosis is extremely rare, with only one case documented in the literature to date.

Background: Focal nodular hyperplasia (FNH)-like lesions are hyperplastic formations in patients with micronodular cirrhosis and a history of alcohol abuse. Although pathologically similar to hepatocellular carcinoma (HCC) lesions, they are benign. As such, it is important to develop methods to distinguish between FNH-like lesions and HCC.

A 9-year-old, presumed male castrated mixed breed dog was evaluated for lethargy, hyporexia, polyuria, polydipsia and diffuse gynaecomastia. Bloodwork revealed severe hypercalcaemia and hyposthenuria. CT scan showed a caudal abdominal mass consistent with a Sertoli cell tumour on cytology.

Adrenal diseases pose significant diagnostic challenges due to the wide range of neoplastic and non-neoplastic pathologies. Radiologists have a crucial role in diagnosing and managing these conditions by, leveraging advanced imaging techniques. This review discusses the vital role of computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine in adrenal imaging, and focuses on morphological and functional evaluations.

Background And Aim: Ex vivo fluorescence confocal microscopy (FCM) systems are innovative optical imaging tools that create virtual high-resolution histological images without any standard tissue processing, either freezing or fixing in formalin and embedding in paraffin. These systems have opened an era that would revolutionize pathological examination by providing rapid, real-time assessments across various pathology subspecialties, potentially replacing conventional methods that are tissue- and time-consuming. This study aimed to present the first utilization of FCM in pediatric surgical oncology, focusing on assessing the benefits, particularly in facilitating rapid and accurate diagnosis.
