Objectives:
Epithelial-myoepithelial carcinoma is a rare tumor of the salivary glands with an incidence of less than 1%. Most cases arise in the parotid gland. Extraoral location is exceptional. The purpose of this study was to describe a case with nasal location, which is exceptionally reported in the literature.
Materials And Methods:
We report a case of epithelial-myoepithelial carcinoma arising in the nasal cavity of a 54-year-old woman.
Results:
The woman presented with right recurrent epistaxis and on nasal endoscopic examination was found to have a polypoid tumor in the right nasal cavity. The CT-scan demonstrated a soft tissue mass without extension to the rhinopharynx or bony destruction. Histopathologic examination revealed the tumor to consist of a mixture of a solid, tubular, and trabecular structures with a double-layered arrangement of inner eosinophilic cells and outer clear cells. Dual differentiation toward myoepithelial and epithelial cells was confirmed immunohistochemically.
Conclusion:
The occurrence of epithelial-myoepithelial carcinoma in the nasal cavity is possible. In published cases, no recurrence or metastasis has been reported in this location.

Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
