Primary mucoepidermoid carcinoma (MEC) of thyroid is an uncommon tumour and reports on its' cytology are consequently scanty. A 46-year-old male presented with a thyroid nodule of nine months duration. Fine needle aspiration (FNA) cytology of the nodule showed features of a malignant tumor that was different from the usual types of thyroid carcinoma. Monolayers and syncytial clusters of round and spindle tumour cells with large vesicular nuclei and single macronucleoli were present. A diagnosis of carcinoma was given with the comment that this was unlike any of the usual types of thyroid cancer and that a metastatic malignancy should be ruled out. The cytological picture of MEC may not always be distinctive enough for accurate tumour typing. Nevertheless the cytological features are usually sufficiently different to rule out all of the usual types of thyroid carcinoma. This distinction may be important from the point of view of differing prognosis in MEC of thyroid (as compared to differentiated thyroid cancers) and the need to exclude a metastatic carcinoma, especially from a primary in one of the salivary glands.
We report a case of High grade Mucoepidermoid carcinoma of the middle ear. A 67 year old gentleman was referred to our centre for persistent otalgia associated with facial weakness for four months. Examination revealed a middle ear mass with House Brackmann Grade 3 Facial Palsy and ipsilateral lymhadenopathy. Biopsies suggested a squamous cell carcinoma of the middle ear, and he successfully underwent an Extended Temporal bone resection with External canal reconstruction and neck dissection. Postoperative Histopathology revealed that the tumour was in fact a High Grade Mucoepidermoid carcinoma. He received postoperative radiotherapy and is well one year post operatively.
We report an extremely rare case of mucoepidermoid carcinoma of the nasal septum. A patient with a history of right-sided nasal obstruction presented to our clinic. Clinical examination revealed a mass in the right nasal cavity originating from the nasal septum. Biopsy revealed a high-grade mucoepidermoid carcinoma. The patient was treated with surgical resection only. Surgery alone might be suitable for small tumors when direct inspection of the surgical site is feasible to detect early recurrence.
