RESUMO
Mastocytosis is a rare disease characterized by proliferation and accumulation of mast cells in various organs. The maculopapular cutaneus mastocytosis is divided into three subtypes: papular/plaque variant, urticaria pigmentosa and eruptive macular telangiectasia perstans. Dermoscopic may help to better characterize the different forms of cutaneus mastocytosis. We report a 55 year-old female with urticaria pigmentosa and its dermoscopy.

A dermatoscopia pode ajudar a caracterizar melhor as diferentes formas de mastocitose cutânea. Relatamos um caso de paciente feminina de 55 anos com urticária pigmentosa e sua dermatoscopia.

Cutis laxa is a rare inherited or acquired disorder of elastic tissue characterized by inelastic and loose skin. Congenital cutis laxa may present with internal organ involvement, determining a worse prognosis. The authors present the case of a female patient with clinical manifestations suggestive of the hereditary form of the disease, with consanguineous parents (second-degree cousins) and a brother who died with a similar clinical presentation. The genetic study of the FBLN5 gene was important to confirm the diagnosis, define the prognosis, and provide genetic counseling to the family.

A Cútis laxa é uma doença rara, hereditária ou adquirida. Resulta da alteração do tecido elástico, tornando a pele frouxa e inelástica. A forma congênita tem geralmente acometimento sistêmico, com pior prognóstico. Os autores relatam o caso de uma paciente, com quadro clínico sugestivo da forma hereditária da doença, com pais consangüíneos (primos de 2º grau) e irmão falecido com clínica semelhante. O estudo genético do gene FBLN5 teve importância na confirmação diagnóstica, na definição do prognóstico e no aconselhamento genético familiar.
