Poroma (poroid tumor), a benign adnexal tumor, usually originates from the terminal duct of sweat glands. Initially, Pinkus et al described poroma and its differentiation in 1956, which was initially believed to be of eccrine origin. However, further research has revealed cases of apocrine, sebaceous, and follicular differentiation. Some authors describe this neoplasm as "acrospiroma," whereas others consider poroma as a broad group of neoplasms, including nodular hidradenomas, clear cell hidradenomas, hidroacanthoma simplex, dermal duct tumors, and hidradenoma. Poroma can exhibit potential degenerative progression. Porocarcinoma, its malignant counterpart, typically develops after several years from a preexisting poroma.
汗孔瘤（孔状肿瘤）是一种良性附属器肿瘤，通常起源于汗腺的终末导管。最初，平库斯等人在1956年描述了汗孔瘤及其分化情况，最初认为它起源于小汗腺。然而，进一步的研究发现了大汗腺、皮脂腺和毛囊分化的病例。一些作者将这种肿瘤称为“顶泌汗腺腺瘤”，而另一些人则认为汗孔瘤是一大类肿瘤，包括结节性汗腺瘤、透明细胞汗腺瘤、单纯性汗腺棘皮瘤、皮肤导管瘤和汗腺瘤。汗孔瘤可能会出现潜在的退行性进展。其恶性对应物汗孔癌通常在已有汗孔瘤数年之后发生。
