Clinical Summary:

This 74 year old male had a long history of mycosis fungoides and now presents with oral erosive lesions and an ulcerated tumor in the upper gingival mucosa. The patient also complaint of recent onset of daily fevers, asthenia and anorexia. Past medical history is significant for peptic ulcer disease and hyperlipidemia.

On examination multiple erythematous papulosquamous patches and plaques were noted mostly involving the extremities and face. The oral mucosa showed extensive erosive patches with an ulcerated tumor on the gingival mucosa. There was no evidence of lymphadenopathy or organomegaly.

A biopsy of the oral mucosa showed a tumor composed of intermediate size uniform mononuclear cells with cytoplasmic TIA-1 expression.
