BACKGROUND Schwannomas are slow-growing benign tumors. They can arise from any peripheral nerve, including the cranial nerves (except the olfactory and optic nerves), spinal nerves, and autonomic nerves. Schwannomas of the head and neck account for 25-40% of all cases. However, intra-oral schwannomas account for only 1% of all head and neck tumors. Complete surgical excision is the treatment of...

A pronounced species variation in the organization of filiform papillae has been observed. Preliminary histologic studies of cat tongue revealed marked regional variations in size, shape and organization of filiform papillae. Therefore, a correlated light microscopic, transmission and scanning electron microscopic study of tissue samples of representative areas of the cat tongue was undertaken ...

BACKGROUND Successful tongue reconstruction after total glossectomy for advanced tongue or base of tongue cancer should restore swallowing, speech function, and cosmesis. METHODS The anterior lateral thigh flap sensitive myocutaneous (ALTF) with vastus lateralis muscle was used to reconstruct the oral defect in a patient undergoing total glossectomy with laryngeal preservation for T4 tongue c...

Tuberculous glossitis is a rare entity that has been described sporadically. Primary tuberculous glossitis, as described in this case report, is still exceptional. A 25-year-old male with no known immunosuppressive disorder presented with a tuberculoma at the base of his tongue. This was confirmed by tongue biopsy and a positive polymerase chain reaction response to the mycobacterium. The patie...

Schwannomas are slow growing, encapsulated neoplasms that arise from the nerve sheath. A vast majority of these benign neoplasms occur in the head and neck region, most commonly involving the 8th cranial nerve. Schwannomas arising from the base of tongue are very rare and, thus, can easily escape the list of differential diagnosis for a posterior tongue mass. A systematic approach is recommende...

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 ...

Osseous lesions of the tongue, also referred to as osseous choristomas, are benign growths of bony tissue. These lesions are not true neoplasms but rather represent growth of normal tissue at an abnormal location. Clinically, they appear as exophytic masses of the tongue, and they are treated by surgical excision. Lingual osseous choristomas are rare entities, with only 71 reported cases in the...

The extranodal malignant lymphomas occur mainly in the region of the head and neck, after the gastrointestinal tract. The most common site of the head and neck lymphoma is at the lymphatics ring of Waldeyer, followed by the nasosinusal region. Localization at the base of the tongue is extremely rare. The authors reported a case of a 50-year-old male with a non-Hodgkin's lymphoma, which develope...
