[Myoepithelioma of the nose].

A 64-year old female, with no other history of interest, presented with anosmia and nasal obstruction which had evolved over several months. Diplopy had also appeared during the last month. On physical examination left-sided exophthalmos was observed. An endoscopy disclosed a tumour which completely obstructed the left nasal fossa. A biopsy of the lesion was performed, which caused moderate epistaxis that required anterior packing. The CT scan showed a large, extensive tumour in the left nasal fossa, spreading into the nasopharynx, which had reshaped the adjacent bone structures and caused ipsilateral pansinusal obstruction (Fig. 1A). The MRI disclosed a solid tumour, with internal cystic areas, well-defined contours, heterogenous in appearance and with no signs of intracranial invasion (Fig. 1B). Biopsy findings were of myoepithelioma with fusocellular components of salivary gland type. The nonaggressive nature of the tumour facilitated endoscopic resection and there were no complications. Histologically, the tumour specimen confirmed the presence of mixed stroma myoepithelial cells (Fig. 2A and B), tested positive for cytokeratin, vimentin and S-100 protein (Fig. 2C and D). Since the patient’s progress was good, it was decided to refer check-ups to the outpatient department.
