The Great Impostor: A challenging case of small-cell melanoma with isolated adrenal metastasis.

ABSTRACT

Small-cell melanoma masquerading as an adrenal non-Hodgkin lymphoma. The index report illustrates the deceptive cytomorphologic features of a small cell type malignant melanoma metastatic to the adrenal gland. The diagnosis was confirmed by performing immunocytochemistry on the cell block sections. The key cytomorphologic mimics and their distinctive features have also been highlighted.
