A Case of Myoepithelioma of the Nasal Cavity
Abstract:
Myoepithelioma is a rare tumour of the salivary glands. Only 3 cases of myoepithelioma in the nasal cavity have been reported. A 29 year old male presented to us with epistaxis and nasal obstruction. There was a fleshy mass occupying the right middle meatus. Biopsy showed evidence of myoepithelioma and an endoscopic excision of the tumour was done. Histopathological examination of the resected tumour was consistent with myoepithelioma. Due to its rarity, the nature of the tumour is not known and regular follow-ups are needed for early detection of recurrence and malignancy.

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...
Classification of Epithelial Tissues: Simple Epithelium
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...
