Carcinosarcoma of Tongue with Predominant Osteosarcomatous Component

Carcinosarcoma of buccal mucosa: A case report

Carcinosarcoma is an extremely rare variant of squamous cell carcinoma characterized by biphasic histology defined by epithelial and mesenchymal components. Because of the aggressive nature, early risk of metastasis, and high mortality, this tumor is associated with poor prognosis. Surgery is considered as the main modality of treatment, although radiotherapy can be discussed in inoperable cases. The present paper describes a rare case of carcinosarcoma of buccal mucosa.

A Case Report of Carcinosarcoma of the Tongue Mimicking a Fibroma: An Enigmatic Lesion With a Diagnostic Dilemma

Carcinosarcoma of the tongue is a rare biphasic tumor composed of squamous cell carcinoma (SCC), either in situ and/or in invasive form, and a mesenchymal component but of epithelial origin. It is important to diagnose this variant because of its aggressive nature and tendency to metastasize early. The present report describes the case of a carcinosarcoma of the tongue in a 48-year-old male with a short history of 30 days, the clinical feature of which resembles that of an irritational fibroma. The diagnosis often represents a clinicopathological challenge where the study with immunohistochemical technique (IHC) is key to the histopathological diagnosis. We here present a case report of this rare tumor, with an unusual presentation, to contribute in part to better understanding and awareness of this rare malignancy.

A Case Report of Spindle Cell Carcinoma with Osteoid and Cartilage Formation in the Tongue

Spindle cell carcinoma (SCSCC) with osteoid and/or cartilage formation in the head and neck is rare; only one case was reported in the tongue. Herein, we report an SCSCC with osteoid and cartilage formation of the tongue developed in an 85-year-old man, and then review the report.
