Lymphangitic Sporotrichosis in a Florist: Clinical, Mycological and Therapeutic Correlation

Abstract

Sporotrichosis is a subcutaneous mycosis caused by fungi of the Sporothrix complex *Schenckii*, with a worldwide distribution and higher prevalence in the tropical and subtropical regions of the Americas, is commonly acquired through traumatic inoculation with contaminated plant material and can manifest as a nodular lymphangitic syndrome, characterized by subcutaneous nodules arranged linearly along the lymphatic vessels. The objective of this study is to describe a clinical case of cutaneous lymphangitic sporotrichosis, highlighting its clinical presentation, diagnosis, and treatment. A 44-year-old male patient, with Fitzpatrick skin phototype V/VI, presented with a dermatosis located on the dorsum of his right hand, characterized by a single ulcer and multiple erythematous nodules arranged linearly that extended to the axillary region. The diagnosis was confirmed by clinical, epidemiological, and mycological findings. Antifungal treatment was initiated, with a favorable clinical outcome. This case highlights the importance of considering sporotrichosis in the differential diagnosis of linear nodular lesions, especially in endemic areas, since early recognition and timely treatment allow for a satisfactory recovery.
