Papillary eccrine adenoma, an entity first recognized in 1977, is a rare cutaneous tumor that can be troublesome to the dermatopathologist.1 This tumor, previously regarded as occasionally malignant, can be accurately diagnosed microscopically and appears to follow a benign course. Because of the changing opinion concerning the biologic nature of papillary eccrine adenoma, we thought it worthwhile to present our experience with two additional cases of this tumor.
Report of Cases
A 66-year-old black man had had a flesh-colored, asymptomatic tumor on the right thigh for 14 years. On examination, the lesion measured 3 × 2 × 0.5 cm; its surface was smooth at the periphery but irregular and verrucous in the center (Fig 1). There was no lymphadenopathy, and the remainder of the patient's physical examination results were normal. The lesion was surgically excised. No evidence of recurrence or metastases was observed two years later.
