t(1;22)(q23;q12) in myoepithelioma

[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 epi...

Myoepithelioma of Tongue

Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is...

Recurrent Benign Myoepithelioma of the Auricle

Myoepithelioma, a generally benign tumor comprised of myoepithlial cells, is an uncommon salivary gland tumor. Myoepithelioma originates primarily in the parotid gland, but several isolated cases have been described. Although myoepithelioma has a benign nature, but there is a potential risk of malignant change and recurrence in case of incomplete resection. We acknowledge that benign myoepithel...

Myoepithelioma of Soft Tissue and Bone

Intraosseous myoepithelioma: a rare, distinct tumor entity.

Primary musculoskeletal myoepithelial tumors (METs) are distinctly rare tumors and are being increasingly recognized as a result of improved diagnostic criteria and objective confirmation with immunohistochemical markers, including epithelial markers. Recent studies have unraveled distinct molecular mechanisms underlying these tumors. Herein, we present our second diagnosed case of an intraosse...
