Summary
Primary cutaneous cryptococcosis, a rare fungal skin infection, affects HIV-negative individuals. Early diagnosis and oral antifungal treatment lead to excellent outcomes.
Area of Science:
- Dermatology
- Infectious Diseases
- Mycology
Background:
- Primary cutaneous cryptococcosis is an uncommon skin infection resulting from direct inoculation.
- This case series focuses on HIV-negative patients diagnosed between 1990 and 1999.
Observation:
- The study included four HIV-negative patients with a mean age of 70.
- Risk factors included exposure to soil/birds (3 patients) and trauma (2 patients).
- Lesions presented as ulcerated nodules, abscess, or cellulitis, primarily on the hands.
Findings:
- Diagnosis was confirmed by cultural examination.
- Treatment with fluconazole, ketoconazole, or itraconazole resulted in healing within months.
- Underlying conditions included chronic lymphocytic leukemia, Waldenstrom's macroglobulinemia, and CD4 lymphopenia.
Implications:
- Altered immunological status is a key factor in developing primary cutaneous cryptococcosis.
- Clinical presentation often mimics papules or ulcerated nodules.
- Prompt treatment with oral azole antifungals ensures an excellent prognosis for skin lesions.
