Malignant fibrous histiocytoma (MFH) can occur as a rare mesenchymal neoplasm of the deep structures of the head and neck region. An unusual case of MFH of the tongue is described in a 61-year-old male. The primary tumour measured 90 X 50 X 30 mm. Treatment consisted of hemiglossectomy in continuity with a supra-omohyoidal neck dissection. The patient has been free from disease for 2 years. The...

Clear cell carcinoma of the base of the tongue is a rare minor salivary gland neoplasm, and to our knowledge, the MR imaging appearance of this entity has not been described. We present the MR imaging findings in such a case and review the differential diagnosis for tongue base masses in an adult.

Adenoid cystic carcinoma is a malignant neoplasm arising from the salivary glands. The most striking feature of this tumor is that it is locally aggressive, with perineural invasion, tendency to metastasize, high recurrence rates. The parotid gland is the most commonly affected site in the head and neck region, tongue being relatively rare. The current study presents a rare case of 6 years old ...

Granular cell tumor (GCT) is an infrequent and usually benign neoplasm which is found predominantly in the head and neck region. More than half of the head and neck GCTs originate from the tongue. It is most frequently seen in the fourth to sixth decades of life. We presented an interesting case of a giant GCT in a 2.5-year-old patient. It was located under the anterior tongue, filled the floor...

Spindle cell lipoma (SCL) is a benign lipomatous tumor predominantly occurring at the posterior neck and shoulder area. Face, forehead, scalp, cheek, perioral area, and upper arm are less common sites. In oral cavity, it is a relatively uncommon neoplasm, particularly in tongue, which is relatively devoid of fat cells. We present a case report of SCL located on the left lateral border of the to...

Chondrosarcoma of the head and neck is uncommon and reported to constitute between 1% to 12% of all chondrosarcoma cases.1, 2, 3 Extraskeletal chondrosarcoma of the tongue is an extremely rare type of neoplasm with only three previously reported cases. The underlying origin of chondrosarcoma arising in the tongue is controversial. We describe a case of a low-grade chondrosarcoma arising in the ...

Schwannoma is a rare benign neural neoplasm derived from Schwann cells of the peripheral nerve sheath. Schwannoma accounts for 25% to 48% of all neoplasm cases in the head and neck region. Oral Schwannoma is an uncommon soft tissue tumor comprising of 1% of all Schwannomas. Tongue is the most common location for oral schwannoma. Occurrence of gingival schwannoma is very rare and less than 10 ca...
