Sweat gland proliferations in scleromyxedema.
Eccrine sweat duct proliferations may be found in various inflammatory and neoplastic skin lesions. We report a patient with scleromyxedema with extensive proliferations of intradermal sweat ducts. Three-dimensional reconstruction demonstrated extensive coiling and branching of the sweat ducts leading into cystic lacunae. In contrast to the basal cell carcinoma that had grown within the scleromyxedematous skin, the ducts close to the lumen stained positive for carcinoembryonic antigen and could therefore be differentiated from basal cell carcinoma. In micrographically controlled surgery of cutaneous epithelial tumors that are located in chronically inflamed skin, such sweat gland proliferations have to be considered as differential diagnosis.
