Primary Cutaneous Cryptococcosis
The differential diagnosis upon initial examination may be wide. Patients generally present with a new skin lesion that proves to be refractory to conservative or traditional therapy. The upper extremities are the most common site of PCC. In almost all cases, a previous injury at the site of inoculation can be identified. Risk factors for exposure to Cryptococcus include residence in a rural area and contact with soil contaminated by avian droppings. The average time between skin injury and onset of symptoms has been reported as 2.5 days. Although rare, it is possible for a patient to present with multiple sites of infection in the absence of dissemination. This is almost exclusively seen in immunocompromised hosts.
Because of its widely variable clinical manifestations, PCC is a diagnosis made by culture and histology. Histopathology reveals numerous yeasts and a giant cell inflammatory process. In PCC, serology should not demonstrate Cryptococcus antigen, as the disease is localized to the skin. Patients diagnosed with PCC should undergo proper work-up to rule out the possibility of an underlying immunosuppressive condition, such as infection or malignancy.
Therapy for PCC can be solely medical or a combination of medical and surgical treatments. Surgical de-bulking in combination with 6-12 months of fluconazole is often used. Early treatment is essential, as cases of Cryptococcus dissemination secondary to PCC have been reported.
This patient's workup did not reveal any underlying immunodeficiencies. He worked with heating, ventilation and air condition (HVAC) in Spain. He was referred to infectious disease and admitted to the hospital for intravenous antifungal therapy.
