title: Pityriasis lichenoides chronica in black patients.
abstract: 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.
