This collection of images clearly illustrates the peripheral net-like configuration of confluent and reticulated papillomatosis (CARP) patches or plaques. Note that CARP is most commonly found on the trunk, neck, and axillae.

It is no surprise that CARP is often mistaken for acanthosis nigricans, given the sometimes velvety texture, or tinea versicolor due to its similar morphology and anatomical distribution. It is important to note endocrine comorbidities and the absence of fungal elements on KOH prep tests when diagnosing.
