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