Porokeratosis is a condition characterized by abnormal epidermal keratinization with a unique morphology of papules or plaques surrounded by a thread-like border of scale corresponding to the cornoid lamella on histology. Many established subtypes have been described; however, genitogluteal porokeratosis is a rare entity. We present the case of a 58-year-old male with pruritic reddish lesions affecting the genitals and thighs, diagnosed with genital porokeratosis. This case highlights features of this rare and diagnostically challenging subtype of porokeratosis.
汗孔角化症是一种以表皮角质化异常为特征的疾病，其丘疹或斑块具有独特的形态，周围有一条线状鳞屑边界，在组织学上对应于角样板层。已经描述了许多既定的亚型；然而，臀生殖器汗孔角化症是一种罕见的病症。我们报告一例58岁男性，其生殖器和大腿出现瘙痒性红色病变，诊断为生殖器汗孔角化症。该病例突出了这种罕见且诊断具有挑战性的汗孔角化症亚型的特征。
