Confluent and reticulated papillomatosis (Goujerot-Carteaud syndrome)

11 May 2012, by KOEPPEL M.-Ch.

Confluent and reticulated papillomatosis of Goujerot and Carteaud is a rare and benign disease that affects young people. It is characterised by the appearance of small, brownish hyperkeratotic papules. The lesions are asymptomatic and typically located in the intermammary and interscapular areas and may potentially spread to other locations.

The cause of confluent and reticulated papillomatosis is not known, i.e. keratinization disorder, abnormal response of the individual to follicular bacteria or to Malassezia (oval Pityrosporum) or to actinomyces.

There are many treatment options: antifungals, vitamin A derivatives, vitamin D derivatives, antibiotics. Cycline antibiotics appear to be the most effective treatment. The expected benefits of treatment must be weighed up against potential side effects. Relapses are possible despite good initial response to treatment.
