ABSTRACT
Schistosomiasis is best known in its visceral form but it can attack the skin, its ectopic cutaneous manifestation being rare and clinically difficult to diagnose. It is characterized by isolated or coalescent papules, erythematous, pruritic or asymptomatic, with zosteriform distribution, often located on the trunk. The authors report a case of a 28-year-old female patient with lesions on the abdomen, with positive stool results for Schistosoma and absence of active symptoms of visceral disease. The case reveals rare exuberant cutaneous manifestation and the importance of the diagnosis of this entity in patients from endemic regions.

Poromas are uncommon benign neoplasms originating from the terminal ductal portion of the sweat glands, mainly characterized by skin-colored or pink pa pules or nodules, usually on the extremities. Due to their rarity, the pigmented form clinical hypothesis is hardly ever suggested and psychopathology is fundamental. We report a case of pigmented eccrine poroma in the right palmer area, a location considered atypical. We stress the importance of dermoscopy as a method for diagnosis of poromas, especially in the differential diagnosis with other pigmented nodular-popular lesions.
Os poromas são neoplasias benignas incomuns oriundas das porções ductais terminais das glândulas sudoríparas. Caracterizam-se principalmente por pápula ou nódulo cor da pele ou róseo, em geral nas extremidades. Devido à raridade, a hipótese clínica da forma pigmentada dificilmente é aventada, sendo fundamental a histopatologia. Relata-se caso de poroma écrino pigmentado na região palmar direita, localização considerada atípica. Ressalta-se a importância da dermoscopia como método auxiliar no diagnóstico do poroma e, principalmente, no diagnóstico diferencial com outras lesões pápulo-nodulares pigmentadas.
