Abstract: 70 yo man with a five year history of exophytic nodules on the lower extremities.
HPI: A 70 year old white male presented with a five year history of exophytic nodules on the lower extremities. They were increasing in number. A few had been removed by shave excision, and the areas that were treated did not regrow.
Over the past few years he had numerous nodules measuring up to 4 cm in diameter. A few of them were excoriated and crusted. There was no lymphadenopathy. He also had extensive areas of erythema and scale on his forearms, upper arms, and thighs.
He had been in the Navy over 50 years ago and served in Japan. He also went to Bangkok and Hong Kong 20 years ago. No significant past medical history

O/E: On the pre-tibial area the patient has multiple nodular lesions, as well as some erythematous and hypopigmented scars where previous lesions have been removed by shave excision. The lesions range from 1 cm to 3-4 cm in diameter.

Pathology: Many biopsies have been performed. In May, 2006, a biopsy showed “superficial perivascular dermatitis of the mixed type, with eosinophilic spongiosis and pustules consistent with an allergic etiology”.
In February, 2007, biopsies of the right anterior and lateral leg showed “marked epidermal hyperplasia, spongiosis, and mixed intraepidermal and superficial dermal inflammatory cell infiltrate”. There was no evidence of malignancy or infection at that time, but there was evidence of chronic venous stasis change.
In January, 2009, we excised another nodule. This was read as “marked epidermal hyperplasia with acute and chronic inflammation” and was negative for fungal, bacterial and acid fast bacilli stains. There is also no evidence of malignancy or carcinoma. Cultures for fungus, anaerobes and AFP were all negative. Flow cytometry was negative.
Diagnosis: What is your differential diagnosis?
Questions: What further information would you want? What additional studies? How would you treat this man?
