Lichen spinulosus (LS) is an uncommon skin condition mostly in children and adolescents but uncommon in adults. It presents as a group of hypopigmented or skin-colored follicular papules and keratotic spines with a sandpaper-like appearance. There is a lymphohistiocytic infiltrate in the dermis centered around hair follicles. We present a rare case of LS in a 52-year-old woman with a rough, bumpy, itchy rash affecting the trunk and extremities. Her rash consisted of clusters of hyperkeratotic follicular-based spiny papules. Histologic sections demonstrated several dilated hair follicles filled with keratotic plugs surrounded by a dense perifollicular lymphohistiocytic infiltrate, particularly at the level of the infundibula, that extended into the follicular epithelium.
棘状苔藓（LS）是一种不常见的皮肤疾病，多见于儿童和青少年，在成人中罕见。它表现为一组色素减退或肤色的毛囊丘疹以及具有砂纸样外观的角化棘，真皮内有以毛囊为中心的淋巴细胞组织细胞浸润。我们报告一例罕见的52岁女性棘状苔藓病例，其躯干和四肢出现粗糙、凹凸不平且瘙痒的皮疹。她的皮疹由成群的以毛囊为基础的角化过度棘状丘疹组成。组织学切片显示几个扩张的毛囊充满角质栓，周围有密集的毛囊周淋巴细胞组织细胞浸润，尤其是在漏斗部水平，并延伸至毛囊上皮。
