Mucosal involvement by lymphomatoid papulosis is very rare but has been reported in the literature. It usually appears as ulcers in patients previously diagnosed of lymphomatoid papulosis. From a histological perspective it is characterized by an infiltrate of CD 30 positive atypical lymphocytes together with a mixed inflammatory infiltrate of eosinophils, neutrophils, histiocytes and plasma cells. We report the case of a man previously diagnosed of lymphomatoid papulosis that developed two ulcerated lesions in the tongue whose biopsy confirmed the diagnosis of oral involvement by lymphomatoid papulosis.
