A 60-year-old woman presented with right sided nasal obstruction and epistaxis for three months. She complained of swelling in the right side of the face, diminution of vision in right eye and headache since last 15 days. The swelling was insidious, slowly progressive without any alleviating or relieving factor. History of pain, loss of appetite and weight loss was elicited. Pain was radiating to the right forehead. There was no history of fever, trauma or vomiting. On clinical examination, mild diffuse swelling was noted in the dorsum of the nose, more on right side measuring 3 cm across extending from midline to 1 cm of right zygomatic arch laterally and from lower orbital margin to right canine fosse inferiorly. Root of the nose, lip, columella and ala were normal. The swelling was tender. Overlying skin was unremarkable. It was firm to hard in consistency. There was no history of hypertension or diabetes and she did not reveal any history of major surgery or illness in the past. A clinical diagnosis of osteoma was suggested. CT scan revealed a mass in the right nasal cavity with erosion of the nasal bone and multiple cannon ball opacities in both lungs suggestive of a primary in the nasal cavity with metastasis to lung. Fine Needle Aspiration Cytology (FNAC) was performed by standard technique from the nose.
DisCussionEMC is a rare low grade malignant tumor of major SG accounting for 1% of SG tumors [1]. Rarely EMC occurs at other sites of seromucinous gland localization, like trachea, bronchus, lacrimal gland, breast, nasal cavity and paranasal sinuses.Flam et al., did a literature search of the previous cases of EMC of the nasal cavity, and found only nine published cases, which indicated that EMC had thus far been described as presenting only Epithelial-Myoepithelial Carcinoma (EMC) is a rare low grade epithelial malignancy of major Salivary Glands (SG). Though the histomorphology of this tumor is distinct, unusual location and clinical presentation may pose diagnostic difficulties especially when this lesion is first encountered at cytology. We report a case of 60-year-old female presenting with nasal obstruction of three months duration. At FNAC the diagnosis of EMC was suggested and it was confirmed on histopathology. We present this case highlighting the cytomorphologic attributes of this rare tumor occurring at an extremely uncommon location -Nasal cavity.[table/ Fig-1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
