CARP: confluent and reticulated papillomatosis PP: prurigo pigmentosa INTRODUCTION Prurigo pigmentosa (PP) is an uncommon, acquired inflammatory disorder with a predilection for young adults of Asian descent. This condition is manifested by highly pruritic, reticulated, and erythematous papules that resolve with hyperpigmentation. Multiple cases of PP have been reported since its initial description in 1971 by Nagashima et al; however, this dermatosis is still underdiagnosed or misdiagnosed. The most significant challenge limiting the identification of PP is successful distinction from confluent and reticulated papillomatosis (CARP). Herein, 2 patientswith PP are described, with a focus on differentiating features from CARP.
