Confluent and Reticulated Papillomatosis With Linear Pseudo-striae: A Description of 20 Cases.

Confluent and reticulated papillomatosis, also known as Gougerot-Carteaud Syndrome, is a rare chronic disease typically affecting young adults. Of unknown etiology, the condition is characterised by oval grayish-brown or erythematous papules that coalesce to form a reticular pattern, usually on the trunk, especially in the intermammary or interscapular region and on the neck. Diagnosis is primarily clinical, based on the appearance of the lesions, the areas affected, and the response to treatment with minocycline. We report 20 cases of patients with histologically confirmed confluent and reticulated papillomatosis who presented linear pseudo-striae, a little known diagnostic sign.
