Epithelioid Enigma: Proximal‐Type Epithelioid Sarcoma in Cyst Fluid Cytology

Diagnostic Cytopathology, EarlyView.
ABSTRACT Epithelioid sarcoma (ES) is a rare, aggressive soft tissue malignancy with substantial morphologic overlap with other epithelioid neoplasms, creating diagnostic difficulty in cytology specimens. We report proximal‐type ES identified in cyst fluid from a lesion clinically interpreted as an epidermal inclusion cyst or abscess.

Eczema‐Like Amelanotic Melanoma: A Diagnostic Challenge

JEADV Clinical Practice, EarlyView.
ABSTRACT Amelanotic melanoma (AM) is a rare and aggressive variant of cutaneous melanoma characterised by the absence of pigmentation, often leading to delayed diagnosis due to its ability to mimic benign inflammatory or neoplastic conditions. We report the case of a 68‐year‐old woman presenting with a slowly enlarging, erythematous, mildly scaling ...

Circumscribed Meningeal Melanocytic Neoplasms: CNS WHO Grade, Molecular Profile, and Clinical Outcomes

Brain Pathology, EarlyView.
In this study including 31 circumscribed meningeal melanocytic neoplasms (melanocytoma, intermediate‐grade melanocytic tumor [IMT], and melanoma), overall survival (OS) differed significantly among the groups, with melanoma showing significantly worse OS than melanocytoma and IMT showing intermediate OS between melanocytoma and melanoma.
