RESUMO
Macrofollicular encapsulated papillary thyroid carcinoma (MEPC) is a rare variant of papillary carcinoma of thyroid with a favourable clinical course. It could be mistaken for a follicular neoplasm or a hyperplastic nodule. We report cytological and histopathological features of this rare variant of papillary carcinoma in a 22 year old female with brief review of literature.

Myoepitheliomas of intraoral minor salivary glands are rare and are usually of plasmacytoid type. Myoepitheliomas are considered difficult to diagnose without the aid of ultrastructural and histochemical studies. Here we present a case report of plasmacytoid type of myoepithelioma of palate that was diagnosed by light microscopic examination alone. Considering the non-specificity of ultrastructural and histochemical findings, it is important to pay attention to typical features of plasmacytoid myoepitheliomas to arrive at a diagnosis.
