Spitz melanoma with MAP3K8::ABLIM1 rearrangement: a case report with review of the literature.
Diagn Pathol
October 2024
Department of Laboratory Medicine and Pathology, University of Minnesota, Mayo Memorial Building 420 Delaware Street SE, Minneapolis, MN, 55455, USA.
Article Synopsis
- - Spitz tumors are rare melanocytic lesions mostly found in younger individuals but can occur at any age. They usually show distinct cellular features and often have mutations or fusions driving their development.
- - A case study details a 43-year-old woman with a malignant Spitz tumor, identified through histological and immunohistochemical analysis showing various protein expressions. Genetic testing revealed a specific fusion gene (MAP3K8::ABLIM1) and additional mutations linked to a poorer prognosis.
- - This case highlights a new variant of MAP3K8 fusion associated with Spitz melanoma, contributing to our understanding of its diverse cellular and genetic characteristics and potential implications for patient outcomes.
Case Report: Cytodiagnosis of pigmented villonodular synovitis involving carpal bones of right wrist.

July 2024
Department of Pathology, Datta Meghe Institute of Higher Education and Research, Sawangi, Wardha, Maharashtra, 442001, India.
Background: Pigmented Villonodular Synovitis (PVNS) is a rare disease of osteoskeletal tissue. Cytodiagnosis of PVNS on fine needle aspiration (FNA) smears is therefore rarely reported. The PVNS usually affects the larger joints.

Department of Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
Article Synopsis
- - Myoepithelial carcinoma (MC) is a rare tumor primarily found in salivary glands and occasionally in soft tissue, displaying both epithelial and smooth muscle characteristics, often affecting the extremities.
- - A case of retroperitoneal MC was accurately diagnosed using cytological findings combined with immunocytochemistry and fluorescence in situ hybridization to identify specific genetic rearrangements.
- - The study highlights the importance of recognizing the unique features of this tumor and using additional testing methods to address diagnostic challenges, as there are very few reported cases of soft tissue MC in medical literature.
Cytological Perspective in a Case of Doege-Potter Syndrome With Hypoinsulinemic Hypoglycemia.

March 2024
Pathology and Laboratory Medicine, All India Institute of Medical Sciences, Bhopal, Bhopal, IND.
Solitary fibrous tumor (SFT) of the lung is a rare mesenchymal neoplasm of uncertain histogenesis, unknown molecular features, and unpredictable clinical behavior, characterized by NAB2-STAT6 fusion. Hypoglycemia accompanying SFT (Doege-Potter syndrome) is an uncommon presentation. We present the cytomorphological features on biopsy imprint smears of a histopathologically confirmed case of SFT of the lung with an uncommon presentation.

A carotid body tumor is a rare form of neoplasm that arises near the carotid artery bifurcation and it has an incidence rate of less than 0.3 per 100,000 population. The low incidence rate of such tumors is due to their origination from the paraganglion cells which is relatively uncommon as compared to other forms of tumor.
