Rhinomaxillary mucormycosis in a renal transplant recipient: case report.

Objectives: Rhinomaxillary mucormycosis is a clinical manifestation of zygomycosis in solid-organ transplant recipients. Without proper diagnosis and treatment, rhino-orbital-cerebral zygomycosis, particularly a central nervous system disease, will develop with substantial complications.

Case Report: A 42-year-old man who had undergone renal transplant was admitted to our otolaryngology department with unilateral bloody nasal discharge.

Expression of Ki67 and P53 in primary squamous cell carcinoma of the larynx.

Unlabelled: We studied a series of untreated laryngeal carcinomas in an attempt to determine the relationship between Ki67 and p53 expression and clinicopathological findings. The relationship between expression of these markers in non-tumoral tissue was also evaluated in order to investigate the possible role of immunohistochemistry as a diagnostic aid in evaluating laryngeal biopsies.

Materials And Methods: Samples from 54 patients with laryngeal squamous cell carcinoma (SCC) were analyzed retrospectively.
