Poroid hidradenomas are uncommon tumors originating from eccrine sweat glands, often presenting as dermal nodules predominantly composed of cuticular and poroid cell types. They belong to the broader category of poroid neoplasms, which include hidroacanthoma simplex, dermal duct tumor, and eccrine poroma. Despite their rarity, poroid hidradenomas require accurate diagnosis and appropriate management due to potential overlaps in their histological features with other adnexal tumors, including digital papillary adenocarcinoma. We report a case of a 56-year-old female presenting with a nodular lesion on the palmar aspect of her right middle finger, which was excised under local anesthesia. Histopathological examination confirmed the diagnosis of poroid hidradenoma, highlighting the importance of maintaining a high clinical suspicion and precise histological evaluation in managing such an uncommon dermatological condition of the finger.
管状汗腺瘤是起源于小汗腺的罕见肿瘤，通常表现为主要由角质形成细胞和管状细胞类型组成的真皮结节。它们属于更广泛的管状肿瘤类别，包括单纯性汗腺棘皮瘤、皮肤导管瘤和小汗腺汗孔瘤。尽管管状汗腺瘤很罕见，但由于其组织学特征与其他附属器肿瘤（包括指状乳头状腺癌）可能存在重叠，因此需要准确诊断和适当处理。我们报告一例56岁女性，其右手中指掌侧出现结节性病变，在局部麻醉下切除。组织病理学检查确诊为管状汗腺瘤，强调了在处理这种罕见的手指皮肤病时保持高度临床怀疑和精确组织学评估的重要性。
