Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud was first typified in 1927. With the help of electron microscopy, it has been elucidated that CRP arises due to aberrant keratinization. However, till date, there is no clear consensus on the etiologic trigger for CRP. Prevailing postulates include a bacterial trigger by Dietzia papillomatosis (type strain N 1280T), an exaggerated cutaneous response to Malassezia furfur, an endocrine basis stemming from insulin resistance, ultraviolet light-induced epidermal change, amyloid deposition, and a loss-of-function mutation in keratin 16. CRP typically presents as asymptomatic hyperpigmented papules and plaques with peripheral reticulation over the nape, axillae, upper chest, and upper back, occasionally with extension superior to the forehead and inferior to the pubic region. Dermoscopy may be used in the evaluation of CRP, but its diagnosis is made on clinical grounds given its nonspecific histopathological findings. Although successful treatment with topical keratolytics, retinoids, or antifungals has been reported, antibiotics, such as minocycline, at anti-inflammatory doses have emerged as a preferred therapeutic option. In this article, we review the diagnostic considerations in CRP and its therapeutic options.

Gougerot-Carteaud syndrome or confluent and reticulated papillomatosis (CRP), was first described by Gougerot and Carteaud as dermatosis. It is generally considered a rare condition. The eruption consists confluent, flat, brown papules localized primarily to the intermammary and interscapular regions with subsequent spread to the breast and abdomen; at the periphery, the papules spread out forming a pigmented reticulated pattern. At present, the aetiology of CRP remains unknown. The two prominent theories are an abnormal host response to fungi and a keratinization defect. Other hypothesis include photosensitivity, genetic factor, amyloidosis cutis and endocrinopathy.

“…9 Although several theories have been proposed as causal factors in CRP, the two most widely accepted ones are that CRP is an abnormal host reaction to M. furfur 13 or a keratinization defect. [2][3][4][5][6][7][8]14 Both theories are not incompatible, since CRP could be an abnormal keratinization disorder determined (or at least triggered) by an anomalous host response to M. furfur. 15 The 'fungal' theory was supported by the detection of M. furfur in cutaneous lesions and the favourable response to antifungal treatments.…”

Confluent and reticulated papillomatosis (Gougerot-Carteaud) successfully treated with tacalcitol

Confluent and reticulated papillomatosis (CRP) is a rare dermatosis of unknown aetiology whose relationship to Malassezia furfur is still debated. Antifungal agents, antibiotics, retinoids, and, more recently, calcipotriol have been successfully used as treatment. The authors report on a 14-year-old female with confluent and reticulated papillomatosis in whom M. furfur was found. Anti-fungal therapy eliminated the fungus, but did not achieve the disappearance of the lesions. Further treatment with tacalcitol was successful, supporting the theory that CRP might be a disorder of keratinization. To the authors' knowledge, this is the first patient treated with tacalcitol for this entity.
