Resumo(s)
Cutaneous diseases in returning travelers encompass a wide spectrum of etiologies and often pose diagnostic challenges. We present the cases of a 50-year-old man and a 57-year-old woman who presented with a 3-month history of erythematous, ulcerated plaques with well-defined elevated borders and a necrotic center on the lower limbs that began 3 weeks after returning from vacation in Costa Rica. Cutaneous biopsy revealed epidermal ulceration and extensive caseating granulomas throughout the full thickness of the dermis. Giemsa staining revealed no amastigotes. Microbiological examinations identified Leishmania braziliensis and excluded mycobacteria and fungi. The diagnosis of cutaneous Leishmaniasis was established. Owing to clinical severity and antimonial unavailability, the man was treated with liposomal amphotericin B. The woman underwent surgical excision of the single lesion, along with oral fluconazole. Complete resolution was documented in both patients. These cases, which posed diagnostic and therapeutic challenges, highlight that cutaneous leishmaniasis, in all its versatile and often perplexing presentations, is a parasitic infection that should always be considered in dermatologic patients returning from vacation in endemic countries.
