## Abstract

Confluent and Reticulated Papillomatosis (CARP) is a rare and benign dermatosis, however, it can cause immense cosmetic insecurities in affected patients. It is most common on the trunk and neck, more common in female patients than male patients, and there appears to be a correlation with overweight and obese body mass index levels. Many of the patients presenting with CARP are adolescents who are especially vulnerable to resultant social isolation and embarrassment due to the cosmetic insecurities they face from CARP. For this reason, prompt diagnosis and treatment of the condition is critical. There are many conditions that can mimic CARP, with acanthosis nigricans being the most common, however, CARP has a much more direct and timely treatment option. We present a case of a 13-year-old female patient with a complaint of a three-year history of stable discoloration to the chest and neck who was able to achieve clearance in just eight weeks with the appropriate treatment.
