Case Report: Ocular Sporotrichosis-A Seven-Case Series.

Ocular infections associated with sporotrichosis can present four clinical manifestations: granulomatous conjunctivitis, dacryocystitis, Parinaud oculoglandular syndrome, and bulbar conjunctivitis. The incidence of ocular sporotrichosis related to zoonotic transmission has significantly increased in endemic regions and is a frequently misdiagnosed cause of granulomatous conjuntivitis. Therefore, we present a series of seven cases of eye injury by Sporothrix strains, including clinical forms, therapeutic approaches, and laboratory procedures to alert health professionals who provide care to these patients.

Ossifying fibroma: an uncommon differential diagnosis for T2-hypointense sinonasal masses.

Ossifying fibroma is a benign fibro-osseous lesion that occurs most commonly in the mandible of female patients. In rare cases, it affects the nasal cavity. The magnetic resonance imaging features may vary depending on the amount of fibrous and bony tissue in its composition. In these tumors, T2-hypointensity is a feature described in the peripheral ossified areas of the lesion, but it may present diffusely, especially when the degree of ossification is extensive. In this scenario, this particular characteristic on T2-weighted imaging is superimposable to the commonly described appearance of other lesions, such as non-Hodgkin's lymphoma, melanoma, and other sinonasal neoplasms with high cellularity and high nucleocytoplasmic ratio. In the present study, we report a case of ossifying fibroma of the nasal cavity that presented as a diffusely and homogeneously T2-hypointense mass, a finding that may cause difficulty in the differential diagnosis with other expansive sinonasal lesions.
