What bacteria causes confluent and reticulated papillomatosis?
Historically, Malassezia furfur was thought to be the cause of the disease, but studies have since shown that patients with confluent and reticulated papillomatosis are not always colonized with Malassezia furfur. The current theory is infection with Dietzia papillomatosis, a gram-positive aerobic actinomycete.
Does confluent and reticulated papillomatosis go away?
Confluent and reticulated papillomatosis is strictly a disorder of the skin that results in cosmetic disfigurement, with no adverse systemic effects; therefore, no treatment is necessary other than for eradication of the rash (see Medication).
What is confluent reticulated papillomatosis?
Confluent and reticulated papillomatosis (CARP), also called confluent and reticulated papillomatosis of Gougerot and Carteaud, is an uncommon skin condition that consists of multiple small, hyperkeratotic macules or papules that coalesce to form patches or plaques with a reticulated (net-like) pattern peripherally.
What causes carp 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.
What are the symptoms of carp?
The clinical presentation of CARP is that of hyperkeratotic or verrucous brown papules that coalesce into plaques with a reticulated periphery. This condition usually occurs on the central trunk in young adults. Histopathologic examination reveals hyperkeratosis, squat papillomatosis, and acanthosis.
Is confluent and reticulated papillomatosis genetic?
Genetics. While most cases of CRP are sporadic, some familial cases have been reported. In some CRP cases, there appears to be been an increased level of keratin production within the granulosum cell layer of the epidermis.
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.
- cryotherapy, or freezing off the tissue.
How do you get rid of carp skin?
Treatment. The treatment of choice for CARP is 2 months of therapy with minocycline or doxycycline, which are effective in most patients.
Is there a cure for carp?
The current treatment of choice for CARP is oral minocycline, 50 to 100 mg, twice daily for 6 weeks. It is unclear how and why minocycline works, but its anti-inflammatory properties may be responsible. Similar to patients with typical CARP, patients with hypopigmented CARP responded well to minocycline.
Is papilloma a benign tumor?
Papillomas are benign growths. This means that they do not grow aggressively and they do not spread around the body. The growths only form in certain types of tissue, although these tissues occur all over the body. Papillomas are often known as warts and verrucae when they reach the skin.
What is Gougerot Carteaud syndrome?
Background Confluent and reticulated papillomatosis (CARP), also known as Gougerot-Carteaud syndrome, is a rare disorder. It usually presents as hyperkeratotic brown papules that coalesce into plaques with a reticulated periphery on the central trunk of young adults.
Should papillomas be removed?
Because there is even a small risk of cancer, papillomas should be surgically removed and biopsied. The difference between a benign and cancerous papilloma cannot always be appreciated after a needle biopsy.
What kind of skin condition is confluent and reticulated papillomatosis?
Confluent and reticulated papillomatosis (CARP), also called confluent and reticulated papillomatosis of Gougerot and Carteaud, is an uncommon skin condition that consists of multiple small, hyperkeratotic macules or papules that coalesce to form patches or plaques with a reticulated (net-like) pattern peripherally.
What is confluent and reticulated papillomatosis ( carp )?
Confluent and reticulated papillomatosis (CARP) of Gougerot and Carteaud is briefly discussed here because of its clinical overlap with acanthosis nigricans. CARP is a rare disorder characterized by hyperpigmented papules confluent in the center and reticulated at the periphery.
What is the mechanism of papillomatosis and reticularis Carteaud?
Zusammenfassung: Die Papillo‐matosis confluens et reticularis Gougerot Carteaud ist eine disseminierte, zu Konfluenz, netz‐förmiger Anordnung und Pigmentierung neigende makulo‐papulöse, teils verruziforme Hauterkrankung unklarer Genese. Pathogenetisch werden verschiedene Mechanismen diskutiert.
Is there a cure for reticulated papillomatosis?
The pathogenesis of AN is unclear. In patients with hyperinsulinemia, insulin may bind to insulin-like growth factor receptors in the epidermis, resulting in papillomatosis (thickening with folding). There are no successful therapies for AN, and the primary focus should be on treatment for the underlying condition.
