Lymphoepithelioid cell lymphoma (Lennert's lymphoma) presenting as atypical granuloma annulare

We describe a case presenting as atypical granuloma annulare where the unde rlying diagnosis, confirmed by lymph node biopsy, was lymphoepithelioid cel l lymphoma (Lennert's lymphoma). Lennert's lymphoma is a peripheral T-cell lymphoma which may follow a variable course and transform into an aggressiv e phase. Cutaneous manifestations of this condition have only rarely been r eported in the literature. The presence of granulomas in the skin may have either obscured the lymphoma infiltrate or may have reflected a more genera lized immune response to the underlying malignancy.
