Eccrine poroma is a benign tumor which arises from the intraepidermal portion of the eccrine sweat glands. It usually occurs as a solitary lesion in the extremity, with the foot and sole as a common site. It may present as a foot mass, ulcerative lesion, bleeding lesion, or suspected melanoma. The clinical diagnosis is often delayed or inaccurate. Three cases of eccrine poroma on the foot are presented. The clinical and histological features, problem in diagnosis, chance of recurrence, and potential transformation to eccrine porocarcinoma are discussed. It is emphasized that eccrine poroma should be considered in the differential diagnosis of chronic foot lesions. Complete excision prevents recurrence, excludes dysplastic change, and prevents future malignant change.
小汗腺汗孔瘤是一种起源于小汗腺表皮内部分的良性肿瘤。它通常表现为肢体上的单个损害，足部和足底是常见部位。它可能表现为足部肿物、溃疡性损害、出血性损害或疑似黑色素瘤。临床诊断常常延迟或不准确。本文报告了3例足部小汗腺汗孔瘤。讨论了其临床和组织学特征、诊断问题、复发几率以及向小汗腺汗孔癌转变的可能性。强调在慢性足部损害的鉴别诊断中应考虑小汗腺汗孔瘤。完整切除可防止复发、排除发育异常改变并预防未来的恶变。
