Resumen

CHIRA, F E  y  STERNBERG, P. Interscapular sporotrichosis. Atypical case report simulating a keloid scar. Rev. argent. dermatol. [online]. 2020, vol.101, n.3, pp.41-50. ISSN 1851-300X.

Sporotrichosis is a subcutaneous mycosis caused by Sporothrix schenkii complex. Its clinical presentation is diverse, but the fixed cutaneous form has a polymorphic evolution, causing a diagnosis delay and wrong treatments that lead to complications. We present the case of a pediatric patient, with no history of traumatic inoculation. Came with a history of a sting-like nodular lesion in the interscapular region. Two months later it ulcerates in the central region and is covered with scabs. The patient self-medicates with a cream that contains betamethasone, clotrimazole and gentamicin, generating temporary remission of the lesion. Subsequently, the lesion reappears and is diagnosed as a keloid scar, treated with infiltration of corticosteroids. A month and a half later, it is also aggravated with pain and itching, and is treated with antibiotics. Without showing any improvement, she went to a dermatological clinic where, by culture, she was diagnosed with fixed granulomatous cutaneous sporotrichosis complicated with Candida spp overinfection. and Staphylococcus aureus.

Treatment with Itraconazole and Potassium Iodide is performed presenting clinical improvement.

The early diagnosis of cutaneous spotrichosis is essential to avoid atypical changes in the evolution of the lesion. The right treatment at the right time minimizes the physical and psychological sequelae in the patient.
