[Large crusted ulceration of the scalp: first manifestation of cryptococcosis in an AIDS patient].

BACKGROUND

Cryptococcosis is an infection caused by the yeast-like fungus Cryptococcus neoformans. It primarily occurs in immunocompromised hosts. Crytptococcosis is usually a systemic disease and may be serious if the lungs or the central nervous system are involved.

CASE REPORT

We describe a case of cutaneous cryptococcosis without systemic involvement occurring as the first manifestation of AIDS. The skin lesion in our patient consisted of a large crusted ulceration on the scalp. Fluconazole was successful.

DISCUSSION

This case is a new observation of primary cutaneous cryptococcosis in a patient with AIDS. Clinical appearance may be misleading; skin lesions may be the primary sign in immunocompromised patients. Rapid treatment and secondary prophylaxis are required.
