A 64-year-old man was noted to have a single pigmented lesion in the nostril of his nose. Clinical examination revealed a 5 mm nodular growth and brown lesion. With a presumed clinical diagnosis of malignant skin tumor, a biopsy was performed. The histological examination revealed the unexpected diagnosis of pigmented inverted follicular keratosis. The inverted follicular keratosis is an uncommon benign lesion that is usually diagnosed histologically rather than clinically. It commonly simulates other proliferative skin lesions.
一位 64 岁男性被发现其鼻腔内有一处单一色素性病变。临床检查发现一处 5 毫米大小的结节性生长和褐色病变。根据临床诊断为恶性皮肤肿瘤，进行了活检。组织学检查显示出乎意料的诊断为色素性倒置滤泡角化病。倒置滤泡角化病是一种不常见的良性病变，通常通过组织学诊断而不是临床诊断。它通常模拟其他增殖性皮肤病变。
