Abstract
in English, Portuguese

Mastocytosis is a rare disease characterized by proliferation and accumulation of mast cells in various organs. The maculopapular cutaneous 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 cutaneous mastocytosis. We report a 55 year-old female with urticaria pigmentosa and its dermoscopy.

A mastocitose cutanea maculopapular divide-se em três subtipos: variante máculo-papular, urticária pigmentosa e telangiectasia macular eruptiva perstans. 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.
