Area of Science:

• Medical Mycology
• Infectious Diseases
• Dermatology

Background:

• Sporotrichosis is a fungal infection caused by Sporothrix schenckii, often associated with soil and plant contact.
• The infection typically presents with skin lesions and can spread to the lymphatic system.

Observation:

• A 40-year-old man developed a finger lesion after swimming in Haiti, followed by forearm nodules and axillary adenopathy.
• Physical examination revealed an eschar on the finger and erythematous nodules on the forearm and antecubital fossa.
• Biopsy confirmed suppurative granulomatous dermatitis, with Sporothrix schenckii identified as the causative agent.

Findings:

• The patient's presentation, including the initial lesion, subsequent nodules, and lymphadenopathy, is consistent with lymphocutaneous sporotrichosis.
• Isolation of Sporothrix schenckii from the biopsy specimen definitively diagnosed the infection.
• The patient's recent travel to Haiti and swimming in the ocean were identified as potential exposure risks.

Implications:

• This case highlights the importance of considering sporotrichosis in patients with endemic exposures and characteristic skin lesions.
• Prompt diagnosis through biopsy and fungal culture is essential for effective treatment and preventing dissemination.
• Public health awareness regarding potential environmental exposures to Sporothrix schenckii in tropical and subtropical regions is warranted.
