Generalized eruptive histiocytoma is considered an extremely rare subtype of non-Langerhans cells histiocytosis. In the literature, there are few reports of this disease that mainly affects adults. In this report, we present a case of generalized eruptive histiocytoma in an elderly patient who had presented symptoms for over two months. Multiple erythematous papules, asymptomatic and symmetrically distributed were observed on the trunk and limbs. Histological examination showed a dense mononuclear cell dermal infiltrate. In the immunohistochemical analysis, the cells were CD68 positive, but CD1a, S100 and CD34 negative. A diagnosis of generalized eruptive histiocytoma was established. The aim of our paper is to report a case of a very rare disease, whose subtype and affected age group are even more unusual.
Sporotrichosis is the most common subcutaneous mycosis. It is caused by the dimorphic
fungus Sporothrix schenckii, and the infection is usually acquired by traumatic
inoculation. We describe a case of sporotrichosis in an uncommon location with an
unusual mode of transmission. A 49-year-old female patient who lived in an urban area
of Rio de Janeiro presented with involvement of the left ear. No history of contact
with soil, plants or animals was elicited. The suspected source of infection was a
pair of handmade wooden earrings. The delay in the diagnosis and treatment resulted
in higher morbidity, unsightly scarring and loss of ear lobe.
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.
