    Abstract:
    OBJECTIVE: To present a clinical report of palatal zygomycosis, its epidemiological, mycological features, and our treatment experience. DESIGN: Retrospective report. SUBJECTS AND METHODS: This is a 25-year long retrospective trial of clinically and mycologically proven cases of zygomycosis. Some patients underwent a biopsy of the palatal lesion and autopsy. This study reports the treatment experience with amphotericin B alone and in combination with itraconazole and fluconazole. RESULTS: Twenty-one cases (18.75%) of zygomycosis with palatal involvement were included in the study, from a total of 112 cases screened. Mean age was 36.5 years, with 18 adults and three children. The associated pre-disposing factors were: ketoacidotic diabetes (five type-1 and 15 type-2), and acute leukaemia in one patient. The clinical varieties were as follows: 19 cases of rhinocerebral (RC) involvement and two disseminated cases. Palatal ulcers occurred in 3/21 early cases (14.3%) and in 16/21 cases after the nasal involvement. All patients received amphotericin B; in four patients, it was combined with itraconazole and four with fluconazole. Clinical and mycological cure was achieved in 4/21 patients (19.04%). CONCLUSION: Zygomycosis with palatal involvement occurs in around 18% of cases, usually associated with RC modalities; it has an acute and generally lethal course.
