Summary of "Cytomorphological Features of Adamantinoma like Ewing's Sarcoma in parotid Masquerading as Sialoblastoma in a pediatric patient."

The incidence of mesenchymal tumors in the salivary gland range from 0.3-1% . Adamantinoma like Ewing sarcoma (ALES) is an unusual variant of Ewing sarcoma with more incidences in the head and neck of young patients, however scarce in salivary gland .

Medical and Biotech [MESH] Definitions

A ubiquitous hnRNP protein found in the CELL NUCLEUS and the CYTOPLASM. Translocations that result in the formation of fusion proteins containing parts of RNA-binding protein EWS may play a role in neoplastic processes such as Ewing Sarcoma (SARCOMA, EWING'S).

A group of highly cellular primitive round cell neoplasms which occur extracranially in soft tissue and bone and are derived from embryonal neural crest cells. These tumors occur primarily in children and adolescents and share a number of characteristics with Ewing's Sarcoma (SARCOMA, EWING'S). They may arise from the chest wall, skin, orbit, kidney, and other structures and tend to be locally invasive or metastasize, although relatively benign forms may occur. Characteristic histologic features include a tendency to form Homer-Wright rosettes and to stain positively with neuron-specific enolase and vimentin. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2113; J Clin Oncol 1998 Mar;16(3):1150-7)

A trans-activator and member of the erythroblast transformation-specific family of transcriptions factors that contain a characteristic ETS MOTIF. It is required for PLATELET CELL ADHESION to the subendothelium and associates with CHIMERIC ONCOGENE PROTEINS in PROSTATE CANCER; EWING'S SARCOMA; and ACUTE MYELOID LEUKEMIA.

An autonomic disorder characterized by excessive sweating of the forehead, upper lip, perioral region, or sternum subsequent to gustatory stimuli. The auriculotemporal syndrome features facial flushing or sweating limited to the distribution of the auriculotemporal nerve and may develop after trauma to the parotid gland, in association with PAROTID NEOPLASMS, or following their surgical removal. (From Ann Neurol 1997 Dec;42(6):973-5)

Tumors or cancer of the PAROTID GLAND.
