A Rare Case of Cutaneous Crystal‐Storing Histiocytosis With Kappa Light Chain Restriction and Unusual BCL6 Expression

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Crystal‐storing histiocytosis (CSH) is a rare histopathologic phenomenon characterized by the accumulation of crystalline material within histiocytes, most often associated with lymphoplasmacytic or plasma cell neoplasms. Cutaneous involvement is uncommon and may present diagnostic challenges.

Multicentric Asynchronous Endocrine Mucin‐Producing Sweat Gland Carcinoma and Mucinous Carcinoma of the Skin

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Endocrine mucin‐producing sweat gland carcinoma (EMPSGC) is an adnexal neoplasm which typically occurs on periorbital skin and demonstrates overlapping histopathologic features with primary mucinous carcinoma of the skin (MCS). Herein, we report a patient who developed five distinct lesions of EMPSGC and MCS over an eight‐year period, some of ...

Superficial Ewing Sarcoma of the Rectum: A Case Report and the Utility of Molecular Diagnostics

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Ewing sarcoma is an undifferentiated small round cell sarcoma that most commonly presents as a malignant bone tumor in pediatric and young adult patients. The diagnosis is typically confirmed by molecular genetic identification of a fusion protein, most commonly involving members of the FET and ETS gene families.

Cytology‐First Diagnostic Workflow for Melanoma of Unknown Primary With Molecular Profiling

Cytopathology, EarlyView.
Cytology‑first diagnostic workflow for melanoma of unknown primary. Fine‑needle aspiration of an enlarged lymph node enables rapid cytologic evaluation and immunocytochemical confirmation of melanocytic lineage (SOX10). This early cytologic diagnosis facilitates timely surgical excision and comprehensive genomic profiling, supporting integrated ...

Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.
