Sporotrichosis must be considered in the differential diagnosis of granulomatous inflammation involving bones and joints. The organisms are difficult to demonstrate in direct smears and in histiologic sections, but they grow readily on routine fungal culture media. The cases of two patients, one with sporothrix arthritis and one with sporothrix arthritis and osteitis, are presented. The latter patient underwent ten surgical procedures over a period of 6 1/2 years and was treated for tuberculous arthritis without a definite diagnosis before fungal cultures were obtained and Sporothrix schenckii isolated.

is one of the leading etiological agents of sporotrichosis, a cutaneous and subcutaneous mycosis worldwide distributed. This organism has been recently associated with epidemic outbreaks in Brazil. Despite the medical relevance of this species, little is known about its virulence factors, and most of the information on this subject is extrapolated from .

This study explores the effectiveness of various antifungal drugs in treating sporotrichosis caused by Sporothrix schenckii, especially in non-wild-type (non-WT) strains. The drugs tested include enilconazole (ENIL), isavuconazole (ISA), posaconazole (POS), terbinafine (TER), and itraconazole (ITC). The study involved in vitro and in vivo tests on 10 WT isolates and eight ITC non-WT isolates.

Background: Conjunctival sporotrichosis is a rare fungal infection, typically presenting as granulomatous lesions. Its manifestations can be atypical, particularly in immunosuppressed patients. Here, we present a rare case of a Mooren's ulcer patient with bulbar conjunctival Sporotrichosis presenting as a salmon-pink tumor.

Granulomatous mastitis is a chronic inflammation of the breast, mostly of unknown etiology. The treatment would be definitive if the causative organism were isolated. It is characterized histologically by granulomas, formed mostly by polymorph nuclear neutrophils and central necrosis.

Sporotrichosis is caused by fungi belonging to the genus Sporothrix, and is generally acquired by traumatic inoculation. A 26-year-old man developed pustular lesions and a 6-kg weight loss after developing a lesion on his right hand 6 months previously. He was diagnosed with acquired human immunodeficiency syndrome (AIDS) and disseminated sporotrichosis cultures of bone and muscle biopsy and blood samples grew Sporothrix schenckii.
