A case of dermal duct tumor (DDT) observed in a 45-year-old male is reported. The lesion was nonspecific clinically. Histological examination revealed dermal tumor masses composed of small, monomorphous basaloid cells arranged around the sweat ducts. There were no atypias and mitotic figures. It is suggested that DDT should be regarded as a distinct eccrine gland tumor that must be differentiated from basal cell carcinoma, hidradenoma, syringoma and above all eccrine poroma.
报告了一例在一名45岁男性中观察到的皮肤导管瘤（DDT）。该病变在临床上无特异性。组织学检查显示真皮肿瘤团块由围绕汗腺导管排列的小的、形态单一的基底样细胞组成。未见异型性和核分裂象。提示皮肤导管瘤应被视为一种独特的小汗腺肿瘤，必须与基底细胞癌、汗腺腺瘤、汗管瘤尤其是小汗腺汗孔瘤相鉴别。
