Eccrine poroma, a common adnexal neoplasm, usually presents as a solitary, smooth, flesh-colored nodule on the foot or hand. Eccrine porocarcinoma is extremely rare and much more variable in its morphology and location. Both tumors can contain melanocytes and melanin. We describe a patient with an enlarging, eroded brownish black nodule on his shoulder. Examination of a biopsy specimen showed it to be derived from acrosyringium and to contain abundant melanin and scattered dendritic melanocytes. Eccrine poroma and porocarcinoma should be considered in the clinical differential diagnosis of pigmented tumors.
小汗腺汗孔瘤是一种常见的附属器肿瘤，通常表现为足部或手部单个、光滑、肉色的结节。小汗腺汗孔癌极为罕见，其形态和部位的变化要多得多。这两种肿瘤都可含有黑素细胞和黑色素。我们描述了一名患者，其肩部有一个不断增大、糜烂的棕黑色结节。对活检标本的检查显示，它起源于末端汗管，含有丰富的黑色素和散在的树突状黑素细胞。在色素性肿瘤的临床鉴别诊断中应考虑小汗腺汗孔瘤和汗孔癌。
