Trichofolliculoma is a rare benign, hamartomatous adnexal tumour of the skin. Aetiology seems to be unclear. It is usually seen in adults, with no gender predilection. The most commonly involved sites are the face and scalp. It appears as a papule or nodule with small protruding hairs, which is a classic feature of the tumour. It has unique diagnostic and histopathological features that help in making a definitive diagnosis. Here, we report an exemplary case of an adult male patient aged 45 years with a gradual progressive diffuse swelling on the left side of the face for 1.5 years. Clinically, it was diagnosed as a sebaceous cyst, but after the biopsy histopathological evaluation was performed, and the diagnosis was confirmed as trichofolliculoma.
毛发滤泡瘤是一种罕见的良性、错构性皮肤附属器肿瘤。病因似乎不清楚。它通常发生在成年人中，无性别倾向。最常见的受累部位是面部和头皮。它表现为一个丘疹或结节，有小的突出毛发，这是肿瘤的一个典型特征。它具有独特的诊断和组织病理学特征，有助于明确诊断。在这里，我们报告了一例 45 岁成年男性患者的典型病例，他的左侧面部有 1.5 年的渐进性弥漫性肿胀。临床上，它被诊断为皮脂腺囊肿，但在进行活检组织病理学评估后，诊断被确认为毛发滤泡瘤。
