Lymphoid lost and found.
We present the clinicopathologic features of a case initially interpreted as lymphocytoma cutis that was later determined to be lymphoepithelioma-like carcinoma of the skin. The histologic presence of nodular aggregates of undifferentiated epithelioid cells surrounded by a dense, reactive lymphocytic infiltrate should prompt consideration of the diagnosis of lymphoepithelioma-like carcinoma of the skin. This lesion should be distinguished from lymphocytoma cutis, B-cell lymphoma, and cutaneous lymphadenoma.
