Sinusitis is a thing that occasionally comes to the pathologist. This article deals with nonspecific sinusitis, i.e. sinusitis without an identifiable cause.
- Sinonasal mucosa.
- Ciliated epithelium.
- +/-Squamous epithelium.
- Subepithelial glands.
- Inflammatory cells.
- Plasma cells - usu. predominant.
MIDDLE TURBINATE, LEFT, EXCISION: - INFLAMED SINONASAL MUCOSA AND BONE. - NEGATIVE FOR MALIGNANCY.
LEFT SINUS TISSUE, EXCISION: - SINONASAL MUCOSA WITH CHRONIC INFLAMMATORY CELLS (PREDOMINANTLY LYMPHOCYTES AND PLASMA CELLS). - NEGATIVE FOR MALIGNANCY.
The sections show mucosa with a ciliated epithelium and bland subepithelial glands. Abundant inflammatory cells, predominantly plasma cells and lymphocytes, are present. There is a lesser amount of neutrophils. Eosinophils are not significant component of the inflammation. There is no significant nuclear atypia. Mitotic activity is not readily apparent. Benign bone is present.
