Abstract excerpt

Pigmented epithelioid melanocytoma (PEM) was originally described based on keen morphologic analysis identifying a group of melanocytic tumors sharing heavily pigmented epithelioid melanocytes. It is defined as heavily pigmented epithelioid, spindled, and dendritic melanocytes with characteristic vesicular nuclei, prominent nucleoli, and melanophages. PEM often involves regional lymph nodes. Recent advances in...
