Results: The tissue from 8 of the 18 patients were used for transcriptome analysis, the results of which were compared with data from public databases. (bvsalud.org)
Methods: Flow cytometric analysis of DNA pliody and S-Phase Fraction (SPF) was done in 50 fresh tumor tissue sections of SGTs which diagnosed as 15 benign and 35 malignant tumors. (researchgate.net)
The tumor is encapsulated by thick connective tissue, but portions may also extend into salivary tissue. (rdhmag.com)
Sometimes it can form in other parts of the body, including your skin, breast tissue, cervix or prostate gland. (indianvartha.com)
MRI gives the best soft tissue definition for salivary neoplasms. (oncologybuddies.com)
Daily adaptive radiotherapy (DART) makes the adjustment before each fraction, allowing for tighter planning of tumor volume margins and less collateral damage to nearby healthy tissue. (medscape.com)
Extraskeletal osteosarcoma (EOS) is a rare malignant soft tissue neoplasm. (researchsquare.com)
Extraskeletal osteosarcoma (EOS) is a malignant tumor of soft tissue origin comprising tumor cells that produce osteoid matrix. (researchsquare.com)
Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. (lookformedical.com)

Usually, in their early stages it is not possible to distinguish a benign tumour from a malignant one. (wikipedia.org)

In some countries, maxillofacial surgeons are also involved in the primary treatment of neoplasm involving the salivary glands. (medscape.com)
Site of the primary tumor was the parotid (7), sublingual (2), and submandibular (1) glands. (icr.ac.uk)
Notably, there are few reports on primary EOS in parotid gland and we report the highly malignant one. (researchsquare.com)

Capsular dissection without formal parotidectomy is a resonable alternative in selected cases due to the benign, non-recurrent nature of the tumor. (stubensaenger.de)

Contrasting information was derived through a literature review by Louredo et al, which indicated that in pediatric patients, most salivary gland neoplasms (75.4%) are malignant. (medscape.com)
A 12-year-old girl patient visited the Department of Pediatric Dentistry, Ataturk University, Erzurum, Turkey, complaining of the pain in maxillar left central incisor (no. 11) and mandibular left lateral incisor (no. 22). (9lib.co)
