“…5) In Korea, so far, a myoepithelioma in the sinonasal cavity has been reported only in the nasal septum and nasal cavity, and no cases in the maxillary sinus have been reported yet. 4,6,7) In this case, a myoepithelioma of maxillary sinus origin was reported for the first time in Korea.…”

“…3) The salivary glands are the most com-mon site of myoepithelioma, but it can also occur in other sites such as the external auditory canal, orbit, and nasal cavity. 4) Given that diagnosis is difficult even for pathologists because of diverse histomorphological and immunohistochemical characteristics, it is important to keep in mind the possibility of myoepithelioma. The occurrence of myoepithelioma in the sinonasal cavity is rare, and only 15 cases have been reported thus far.…”

“…The occurrence of myoepithelioma in the sinonasal cavity is rare, and only 15 cases have been reported thus far. 4) Furthermore, it is not easy to detect the occurrence of myoepithelial tumors in the sinonasal cavity. The growth characteristics of sinonasal myoepithelioma through imaging studies have not been reported yet.…”

Myoepithelioma is a rare tumor of the salivary glands. Occurrence of myoepithelioma in the nasal cavity is even rarer, and there has been no case wherein the change in the size of the tumor was confirmed by imaging. In this report, a 84-year-old female was found to have a rapidly enlarged tumor on the preoperative image, but she had shown no significant size change in a medical examination six months ago or in the paranasal sinuses view three months ago. The image showed a rapid increase in the size of the cystic component, so the endoscopic medial maxillectomy was performed. There was no recurrence of the tumor at follow-up six months after surgery. Although myoepithelioma is rarely found in the maxillary sinus of the sinonasal cavity, it is important to suspect myoepithelioma and consult a pathologist if it shows a similar pattern to the current case.

“…A recent review of English-language literature, published in 2019, revealed only 12 previous cases of sinonasal myoepithelioma, 12 and there have been no subsequent publications of case reports in the literature since this review. Patients present with chronic nasal obstruction without secondary symptoms and with a painless mass on examination.…”

Background Myoepithelioma is a rare benign neoplasm, most commonly derived from salivary glands, but there are limited cases of extra salivary gland involvement too. There is little knowledge on typical investigative findings and, instead, diagnosis relies on immunohistochemistry analysis. To our knowledge, this paper reports the 13th case of sinonasal myoepithelioma in the English literature. Case report This paper presents a 25-year-old man who complained of chronic nasal obstruction. A sinonasal mass was noted on examination that appeared benign on imaging. Biopsy revealed a grade 2 chondrosarcoma that was endoscopically resected; however, excisional margins were positive. On histopathological review at the multidisciplinary team meeting, the lesion was more in keeping with chondromyxoid fibroma, but immunohistochemistry analysis confirmed a myoepithelioma lesion. In light of this revised diagnosis, quorate opinion was for follow up with active monitoring. Conclusion Sinonasal tumours require a thorough history, examination and investigation before a treatment plan can be formulated. If there is diagnostic uncertainty, it is important to keep a wide differential list and seek a second specialist opinion where possible.
