Familial cutaneous papillomatosis, also known as confluent and reticulated papillomatosis, [OMIM|167900] is a rare skin disease characterized by flat, scaly, wart-like lesions.

Presentation

The lesions are about 1 to 2 mm in diameter at the onset, eventually attaining a size of 4 to 5 mm. They evolve in color from bright red to grey and brown. These lesions join up to form larger patches with a net-like pattern on the edges. The first lesions usually appear between the breasts and in the midline of the back and gradually spread over the breasts, to the neck, armpits and abdomen.

Lesions may also spread across the shoulders, in the pubic areas, and on the face. Lesions are mostly asymptomatic, although some patients may have mild pruritus (itching).

Eponym

Henri Gourgerot and Alexandre Carteaud originally described the condition in 1927, [Gougerot H, Carteaud A (1927). "Papillomatose pigmentee innominee". Bull Soc Fr Dermatol Syphilol. 34:719.] for which it can also be referred to as Gourgerot-Carteaud syndrome.
