Adnexal tumors of the skin are rare neoplasms that encompass a wide range of dermatologic entities. Here, we investigated the pattern of adnexal tumors of the skin in the All African Leprosy and Tuberculosis Rehabilitation and Training Center (ALERT) hospital retrospectively.
A hospital-based retrospective study was conducted at ALERT from histopathology records in the Armauer Hansen Research Institute (AHRI) pathology laboratory of patients diagnosed with any of the skin adnexal tumors during the time period January 2017 to December 2021. A structured data extraction sheet was used. Data entry was done using EpiData 4.6.0.6. Data were analyzed using SPSS version 25.
A total of 146 skin adnexal tumors were identified making the magnitude 2.8% of total biopsies. The 3rd decade of life was found to be the most common age group. Male-to-female ratio was 1 : 1.05. Majority of the tumors were benign (82.2%) and had sweat gland differentiation at 48.6%. Poroma (10.9%) was the most frequent tumor, whereas porocarcinoma (6.8%) made up the most frequent malignant tumor. The most common site was the head and neck region (48.6%). Only 21.2% of the tumors were correctly identified clinically.
The magnitude of skin adnexal tumors is found to be slightly higher than other similar studies which could be because it was carried out in the largest dermatologic center in the country. The most common skin adnexal tumors identified, their localizations, and lines of differentiation are all in line with other studies. Histopathologic examination is mandatory for the accurate diagnosis of these tumors.
皮肤附件肿瘤是一种罕见的肿瘤，涵盖了广泛的皮肤科实体。在这里，我们回顾性地研究了全非麻风结核康复培训中心（ALERT）医院的皮肤附件肿瘤模式。
在 2017 年 1 月至 2021 年 12 月期间，在 Armauer Hansen 研究所在 ALERT 医院的组织病理学记录中，对在该机构诊断为任何皮肤附件肿瘤的患者进行了基于医院的回顾性研究。使用结构化的数据提取表。使用 EpiData 4.6.0.6 进行数据录入。使用 SPSS 版本 25 进行数据分析。
共发现 146 例皮肤附件肿瘤，占活检总数的 2.8%。第三十年龄组是最常见的年龄组。男女性别比为 1:1.05。大多数肿瘤为良性（82.2%），具有 48.6%的汗腺分化。汗管瘤（10.9%）是最常见的肿瘤，而汗腺癌（6.8%）则是最常见的恶性肿瘤。最常见的部位是头颈部（48.6%）。临床上只有 21.2%的肿瘤能被正确识别。
皮肤附件肿瘤的发病率略高于其他类似研究，这可能是因为它是在该国最大的皮肤科中心进行的。所确定的最常见的皮肤附件肿瘤、它们的定位和分化线都与其他研究一致。组织病理学检查是这些肿瘤准确诊断的必要条件。
