Confluent reticulated papillomatosis

Introduction to fusion reticular papillomatosis Confluent and reticulate papillomatosis (also known as cutaneous papillomatosis), Gougerot-Carteaud syndrome, first described by Gougerot and Carteaud in 1932, they divided the disease into three types: spotted papilloma , fusion reticular papillomatosis and coin-shaped fusion reticular papillomatosis. Occasionally in the double breast room, the skin lesions are flat, pigmented keratinized papules, partially fused into a network. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: pruritus

Causes of fusion reticular papillomatosis

(1) Causes of the disease

The cause is still unclear. It is thought to be related to Malassezia infection, but the antifungal treatment is not effective, or it is considered to be related to endocrine function changes, such as pregnancy, thyroid dysfunction, Cushing syndrome, etc., but most cases have no endocrine. The change is also considered to be a variant of acanthosis nigricans.

(two) pathogenesis

The pathogenesis is still unclear, and it is thought to be related to Malassezia infection, endocrine function changes, and also a variant of acanthosis nigricans.

Invasive reticular papillomatosis prevention

The disease is a viral infectious disease, and its preventive measures are mainly for the cause, improve the physical condition of the body, and intake of foods with high vitamin C content, which can reduce the risk of infection. For patients exposed to this disease, care should be taken to clean the skin after contact and reduce the risk of viral infection. Patients with existing infections should be actively antiviral therapy to reduce the incidence of complications.

Concomitant reticular papilloma complications Complications pruritus

The disease occurs in the double-breasted room, and the lesion is a flat, pigmented keratinized papule, partially fused into a network. Mainly caused by skin damage, patients can be scratched by skin itching, some patients feel aversion to repeated skin damage caused by papilloma infection, often cut with a nail clipper, if the disinfection is not strict, can cause tetanus infection of skin mucosa, Should be brought to the attention of clinicians.

Symptoms of fusion reticular papillomatosis Common symptoms Pimple round or oval dome... Itching

Occurs in adolescents, women are more common, skin lesions start from a reddish papule, diameter 1 ~ 2mm, hemispherical or flat, gradually increased, up to 0.5cm, grayish brown, slightly keratinized surface Similar to flat warts, the papules are constantly increasing, and they are fused into a sheet or a mesh.

Diagnosis and diagnosis of fusion reticular papillomatosis

diagnosis

According to the incidence of adolescents, pigmented keratotic papules are more common in the milk room, often merged into a network, which can be diagnosed.

Differential diagnosis
