Confluent and reticulated papillomatosis is an uncommon but distinctive acquired ichthyosiform dermatosis characterized by persistent dark, scaly, papules and plaques that tend to be localized predominantly on the central trunk.

[3] Henri Gougerot and Alexandre Carteaud (1897 - 1980) originally described the condition in 1927.

[4] The cause remains unknown, but the observation that the condition may clear with Minocycline[5] turned attention to an infectious agent.

Actinomycete Dietzia strain X was isolated from one individual.

[6] Other antibiotics found useful include azithromycin, fusidic acid, clarithromycin, erythromycin, tetracycline, and cefdinir.
