Abstract:
Disseminated sporotrichosis may present with inflammatory arthritis and cutaneous ulcerations that mimic noninfectious skin conditions such as pyoderma gangreonsum (PG). Sporotrichosis must therefore be ruled out before administering immunosuppressive agents for PG. Furthermore, dimorphic fungi such as sporotrichosis may grow as yeast in bacterial cultures, even before fungal cultures become positive. We present a case of disseminated cutaneous and osteoarticular sporotrichosis mimicking PG and describe the differential diagnosis and the diagnostic and treatment approach to this condition.
