Abstract

Pigmented epitheloid melanocytoma is a recently described entity, low grade malignant lesion, encompassing epitheloid blue nevus of carney complex and animal type melanoma, from which they are histologically indistinguishable. Excision biopsy of skin and lymph node were subjected to histopathological processing and IHC studies. The characteristic histomorphology and positive melanocytic marker in spindle, polygonal and epitheloid cellular components of both the skin and left supraclavicular lymph nodal lesions confirmed the diagnosis. We report a rare case of pigmented epitheloid melanocytoma of the anterior chest wall with metastasis to left supraclavicular lymph node.
