[Case of sycosis candidiasis on the upper lip].

A 72 year-old man was referred to our department with white curd-like material on the surface of his tongue as well as the mucosal surface of the lower lip, after unsuccessful treatment with itraconazole for 3 weeks. He also had a history of depression and had received topical steroid and/or antibiotics treatment for persistent oral aphtha and irritation of his upper lip for 4 years. A diagnosis of oral candidiasis was made through positive KOH direct microscopic examination and he was instructed to rinse his oral mucosal lesion with amphotericin B syrup. Although no significant eruption was observed on his upper lip at his first visit, he applied the steroid ointment for 4 weeks and came back to our clinic with his upper lip red and swollen. It was also covered with yellow crusty material mixed with a pustule. Histological examination of the lips revealed non-specific chronic inflammation in the mid to lower dermis. Hyphae in the cornea detected by PAS and Grocott staining. KOH direct microscopic examination from the pustule and crust showed positive pseudohyphae although no sign of parasitism to the hair was seen. Candida albicans and Candida parapsilosis were detected by culture from the crust and a biopsy sample. He was successfully treated with 2 courses of pulse therapy of oral itraconazole for sycosis candidiasis, accompanied by 2% miconazole gel for oral candidiasis.
