Eccrine poroma is a common benign cutaneous tumor that originates in an intraepidermal eccrine duct. This tumor exhibits acral distribution (sole, palm), and is rarely encountered in the head and neck area. In fact eccrine poroma in the postauricular area has only been rarely reported. A 55-year-old female visited our hospital with a main complaint of a mass that first developed in the left postauricular area about a year previously. The mass was painless, soft, protruding, domed, and dark red in color, and had slowly enlarged (at presentation it measured 1×1 cm). Excisional biopsy was performed. Histological examination showed distinct features, and eccrine poroma was diagnosed. Follow-up at 6 months postoperatively showed no recurrence. The frequency of eccrine poroma is dependent on eccrine sweat glands density, and thus, usually occurs on the palms or soles. For eccrine poroma in the head and neck region, the differential diagnosis must rule out other masses, such as nevus, skin tag, pyogenic granuloma, cyst, basal cell carcinoma, and seborrheic keratosis. Importantly, 18% of poromas show malignant transformation, and can develop into porocarcinoma. For these reasons, an eccrine poroma in the facial area requires histological examination, complete excision, and follow-up.
小汗腺汗孔瘤是一种常见的良性皮肤肿瘤，起源于表皮内小汗腺导管。该肿瘤呈肢端分布（足底、手掌），在头颈部区域很少见。事实上，耳后区域的小汗腺汗孔瘤仅有极少的报道。一名55岁女性因大约一年前首次出现在左耳后区域的肿物为主诉前来我院就诊。该肿物无痛，质地柔软，突出，呈圆顶状，颜色为暗红色，且缓慢增大（就诊时大小为1×1厘米）。进行了切除活检。组织学检查显示出明显特征，诊断为小汗腺汗孔瘤。术后6个月随访未见复发。小汗腺汗孔瘤的发病率取决于小汗腺密度，因此通常发生在手掌或足底。对于头颈部区域的小汗腺汗孔瘤，鉴别诊断必须排除其他肿物，如痣、皮赘、化脓性肉芽肿、囊肿、基底细胞癌和脂溢性角化病。重要的是，18%的汗孔瘤会发生恶变，并可发展为汗孔癌。出于这些原因，面部的小汗腺汗孔瘤需要进行组织学检查、完整切除及随访。
