BACKGROUND
Pilomatrixoma is a benign tumor of the hair follicle that can transform into a malignant lesion, the pilomatrix carcinoma. We present an unusual case of an eyelid pilomatrixoma.
MAIN OBSERVATION
A 37-year-old white male presented with rapidly growing, pedunculated lesion located at the superior right eyelid of five months duration. The lesion was excised under local anaesthesia. The sample was fixed in 10% formalin and histopathological as well as immunohistochemical analyses were performed. Results of both examinations were consistent with a benign pilomatrixoma.
CONCLUSIONS
Even though the lesion had malignant clinical appearance, histopathology confirmed the diagnosis of a benign pilomatrixoma, supporting the decision not to make a more extensive surgery.
背景
毛发上皮瘤是一种毛囊良性肿瘤，可转变为恶性病变，即毛发上皮癌。我们报告一例罕见的眼睑毛发上皮瘤病例。
主要观察结果
一名37岁白人男性，右上眼睑出现一个带蒂的、生长迅速的病变，持续5个月。该病变在局部麻醉下切除。样本固定于10%福尔马林中，并进行了组织病理学和免疫组织化学分析。两项检查结果均符合良性毛发上皮瘤。
结论
尽管该病变具有恶性的临床表现，但组织病理学确诊为良性毛发上皮瘤，支持了不进行更广泛手术的决定。
