Other differential diagnoses include maculopapular mastocytosis, postinflammatory hyperpigmentation, morphea, pityriasis rosea, Addison disease, hemochromatosis, arsenism, contact dermatitis, multiple fixed drug eruption, confluent and reticulated papillomatosis of Gougerot and Carteaud
, tuberculoid leprosy, and pinta.
Confluent and reticulated papillomatosis (CARP) of Gougerot and Carteaud
, also known as Gougerot-Carteaud syndrome, is an uncommon skin disorder of young individuals characterized by hyperkeratotic or verrucous brown papules or plaques that coalesce centrally and by a reticulated pattern peripherally.
Reticulate pigmentation, which is characterized by a mottled appearance and variation in the size and pigmentary content of lesions , is seen in reticulate acropigmentation of Kitamura, confluent and reticulated papillomatosis of Gougerot, and Carteaud
and other rare dermatoses.
Gougerot and Carteaud
papillomatosis: multiple hyperpigmented papules, brownish, 4-5 cm in size, hyperkeratosic, with the tendency of central confluation and peripheral reticular disposition, localized on the presternal area, interscapular area and upper abdomen.
Doisneau confeso entonces que la fotografia habia sido escenificada, pero no con los demandantes, sino con dos estudiantes de teatro, Francoise Bornet y su novio, Jacques Carteaud, a quienes habia contactado dias antes.
Ademas, Jacques Carteaud, que se separo de Bornet pocos meses despues de haber sido fotografiados, declaro que habian recibido un pago de 500 francos por posar, remuneracion que ambos consideraron justa en aquel momento.
In addition, it has been suggested that both PP and confluent and reticulated papillomatosis of Geougerot and Carteaud lie on a spectrum of one disease .
Clinical differential diagnoses include acute lupus erythematosus, dermatitis herpetiformis, linear immunoglobulin A disease, pigmented contact dermatitis, confluent and reticulated papillomatosis of Geougerot and Carteaud, Dowling-Degos disease, macular amyloidosis, and ashy dermatosis [3-5, 8].
Confluent and reticulated papillomatosis of Gougerot and Carteaud
(CRP) is a rare skin disorder characterized by benign blue-gray or brown hyperpigmented hyperkeratotic papules and plaques.
The distribution and morphology of our patient's cutaneous eruption was highly suggestive of confluent and reticulated papillomatosis (CARP) of Gougerot and Carteaud
, a rare dermatologic disorder characterized by epidermal changes (hyperkeratosis, scaling) and hyperpigmentation.
Conditions that can mimic acanthosis nigricans include postinflammatory hyperpigmentation; chronic eczema (especially in children with darker skin and secondary hyperpigmentation or lichenification); and confluent and reticulated papillomatosis of Gougerot and Carteaud
(the plaques in this condition are very similar to acanthosis nigricans, but are more reticulated and located on the chest and back).
