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.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
