What is confluent and reticulated papillomatosis?
Confluent and reticulated papillomatosis (CARP) is an uncommon dermatosis characterized by hyperpigmented scaly macules or papillomatous papules coalescing into confluent patches or plaques centrally with a reticular pattern peripherally (picture 1A-D). It most commonly occurs on the trunk.
How do you get confluent and reticulated papillomatosis?
Confluent and reticulated papillomatosis (CRP), also known as Gougerot-Carteaud syndrome, is caused by disordered keratinization. It presents with asymptomatic hyperpigmented papules that can coalesce into plaques and are typically located on the upper trunk and neck of teens and young adults.
Is confluent and reticulated papillomatosis genetic?
Genetic factors may also be involved. Several cases of familial confluent and reticulated papillomatosis have been reported [9,10]. Mutation of the gene for the protein keratin-16 (K-16) has been found in some cases [11].
What is Gougerot-Carteaud syndrome?

How is confluent and reticulated papillomatosis treated?
Successful treatment of confluent and reticulated papillomatosis has been reported with topical mupirocin. Another therapeutic option in confluent and reticulated papillomatosis may be tazarotene gel. The treatment was well tolerated and may be an alternative to systemic retinoid therapy.

Papillomatosis refers to the projection of dermal papillae above the surface of the skin, resulting in an irregular undulating configuration of the epidermis. Often associated with epidermal hyperplasia, papillomatosis is also seen with chronic inflammatory and neoplastic dermatoses.
What causes carp on skin?
The etiology of CARP is unclear; however, some suggested causes include an inherent keratinization disorder, an endocrinopathy, a reaction to UV light, a reaction to Pityrosporum, and a genetic factor. Clinically, CARP can present with hyperkeratotic papules or patches that coalesce to form a reticular pattern.
How do you treat papillomatosis?
Skin papilloma treatment
- cautery, which involves burning off the tissue and then scraping it away using curettage.
- excision, in which a doctor surgically removes the papilloma.
- laser surgery, a procedure that destroys the wart using high-energy light from a laser.
