Primary Cutaneous Cryptococcosis in an Elderly Patient: A Case Report and Review of Literature.

This article reports an elderly male patient with nodules and ulcers on the face and behind the left ear after trauma. Primary cutaneous cryptococcosis was confirmed using pathological biopsy, special staining, tissue culture, and fungal sequencing. The patient received a therapeutic intervention involving the administration of the antifungal agent itraconazole. Substantial amelioration of cutaneous manifestations was observed after a 3-month course of treatment. After an elapsed interval, the patient was diagnosed with esophageal tumor. Moreover, the literature on 33 patients with primary cutaneous cryptococcosis published in the past 10 years was also reviewed.
