Benign eccrine poroma in the palm of the hand.

Abstract

A 90-year-old, diabetic male presented with a 2-year history of a growing mass in the palm of the left hand. The lesion had gradually increased in size. One year from the onset of the swelling, a foreign body (date palm thorn) was removed from the same site, but there was no regression in the size of the mass or history of discharge. There were no associated neurological or vascular symptoms in the hand. Physical examination revealed a 4 x 3 cm ulcerated, tender, firm and mobile mass in the subcutaneous plane of the hand, which was attached to the skin near the center (Figure 1). Motor and sensory functions were normal and there was no evidence of lymphadenopathy. An x-ray of the hand and hematological tests were normal. Clinically, a foreignbody granuloma was suspected and excision was planned. The whole mass was excised, including an ellipse of skin and subcutaneous fat. Histological examination revealed a benign adnexal neoplasm with a characteristic population of cuticular and eccrine glandular cells with formation of ductal structures and intraluminal secretions (Figure 2). The patient remained well with no evidence of recurrences after one year of careful follow up. Discussion
