Abstract:

A 59-year-old female patient, previously healthy, immunocompetent, presented left bulbar conjunctiva lesions and nodular-ulcerated lesions on the arms and cervical region, besides left cervical and retroauricular lymphadenopathy. She had previous contact with domestic cats that excoriated her face. The diagnosis was conclusive of disseminated sporotrichosis through clinical and epidemiological history and cultures of skin and ocular secretions. It evolved with good response to oral antifungal therapy.

A 59-year-old female patient, without any comorbidities, presented erythema, pain and burning sensation on bulbar conjunctiva (Figure 1) for 75 days. Two weeks later appeared nodules with an ulcerated center on upper limbs and cervical region, together with left cervical and retroauricular lymphadenopathy (Figure 2). After diagnostic hypothesis of sporotrichosis, laboratory tests were requested (hemogram, glucose level, hepatic and renal functions), which were all normal; anti-HIV serology, negative; thorax radiograph, without alterations. Cultures in Sabouraud agar, modified, of secretions from lesions on the arms and eyes showed cream-colored filamentous colonies that changed to brown-black (Figure 3). Microscopy of the colonies revealed thin hyphae, chambered, with daisy-shaped conidia characteristic of Sporothrix spp. The treatment was done with itraconazole 200mg per day for 60 days with complete symptom resolution.

Sporotrichosis is a subacute or chronic disease, more common in the 30 -60 years old; transmission may be by traumatic inoculation in the skin or subcutaneous tissue (more common) or inhalation with possible hematogenic dissemination.¹1 Ramos-e-Silva M, Vasconcelos C, Carneiro S, Cestari T. Sporotrichosis. Clin Dermatol. 2007;25:181-7.^,21 Ramos-e-Silva M, Vasconcelos C, Carneiro S, Cestari T. Sporotrichosis. Clin Dermatol. 2007;25:181-7. It is subdivided into cutaneous (lymphatic, localized and disseminated) and extracutaneous forms.²2 Morris-Jones R. Sporotrichosis.

A case of disseminated cutaneous sporotrichosis is here described in a woman at the expected age, with history of household contact with cats that eventually scratched her face. As the patient presented disseminated lesions, there possibly was hematogenic dissemination from the cutaneous trauma. The diagnostic was made from the clinical and epidemiologic histories associated with positive culture for Sporothrix spp. A total of 143 cases of disseminated sporotrichosis were found in global medical literature, 67 of which were in immunocompetent individuals.
