This case report describes a rare occurrence of inverted follicular keratosis (IFK) in a 27-year-old woman who had a single lesion on the left side of her nose. IFK, which primarily affects older males, is a harmless condition that involves the hair follicles and sebaceous ducts. The patient's lesion, with a size of 0.4 x 0.3 x 0.3 cm, was surgically removed and subsequently identified as IFK through histopathological analysis. This case underscores the significance of including IFK in the list of potential causes for solitary keratotic lesions in younger patients and emphasizes the need for histopathological analysis to ensure an accurate diagnosis. After the surgical removal, the patient did not experience any return of the condition, which aligns with the positive outlook described in the medical literature.
本病例报告描述了一名27岁女性罕见的倒置性毛囊角化病（IFK），其左侧鼻子上有一个单一病变。IFK主要影响老年男性，是一种累及毛囊和皮脂腺导管的无害病症。患者的病变大小为0.4×0.3×0.3厘米，通过手术切除，随后经组织病理学分析确认为IFK。该病例强调了将IFK纳入年轻患者孤立性角化病变潜在病因清单的重要性，并强调需要进行组织病理学分析以确保准确诊断。手术切除后，患者病情未复发，这与医学文献中描述的良好预后一致。
