Eccrine tumours of the hand: two cases.

Two cases of eccrine tumour of sweat gland origin found in the hand are presented. They were non-tender rounded masses of eight months to two years duration, beneath and adherent to the epidermis but movable on underlying tissue. The pre-operative diagnosis in each case was that of a sebaceous cyst. Histology revealed one to be an eccrine spiradenoma and the other a chondroid syringoma. The lesions were considered unusual in that such tumours usually occur on the trunk, head and back and are rarely found in the hand.
