Pityriasis lichenoides chronica (PLC) is a cutaneous disease of unknown etiology that most commonly affects children and young adults. The highly variable presentation of this condition often poses a diagnostic challenge. The clinical presentation of PLC in black patients is not well described. We report a series of 5 black patients (4 children and 1 young adult) with PLC who presented with extensive hypopigmentation and prominent facial involvement. One patient had concomitant mycosis fungoides (MF). The diagnosis of PLC should be included in the differential diagnosis in dark-skinned patients who present with widespread hypopigmented macules and patches. The presence of MF in one of our patients underscores the potential relationship between MF and PLC.
慢性苔藓样糠疹(PLC)是一种病因不明的皮肤病,最常影响儿童和年轻人。这种疾病的表现高度可变,常常带来诊断挑战。关于PLC在黑人患者中的临床表现描述不多。我们报告了5例患有PLC的黑人患者(4名儿童和1名年轻人),他们表现为广泛的色素减退和明显的面部受累。1例患者同时患有蕈样肉芽肿(MF)。对于出现广泛色素减退斑和斑片的深色皮肤患者,鉴别诊断应包括PLC。我们其中1例患者存在MF,这突出了MF与PLC之间的潜在关系。
