title: Sweat-gland carcinomas: prognosis related to histological type.
abstract: A series of 10 sweat-gland carcinomas is reported. The ages of the patients at presentation ranged from 12 to 79 years. Three of the tumours had shown long latent periods with a mass present for up to 20 years. Prognosis proved to be related to the histological subtype. Thus, two papillary syringocystadeno-carcinomas, one recurring cylindroma, one hybrid cylindroma/adenoid cystic carcinoma and two mucoid carcinomas were apparently all cured by surgery. Two mucoepidermoid carcinomas and one histologically malignant chondroid syringoma were not only histologically, but also clinically, malignant. The last case, a chondroid syringoma of benign histology, proved nevertheless to be malignant clinically.
