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 ...

Schwannoma is a benign tumour that arises from Schwann cells of the peripheral nerve sheath, and is a common tumour of the head and neck. However, intraoral location is very uncommon (only 1% of all head and neck schwannomas). We report a rare case of lingual schwannoma in a 20-year-old male patient who presented with a small, slow-growing mass over the right lateral border of the tongue with 1...

Neurilemmoma also known as schwannoma is benign nerve sheath tumor rarely occurring in the oral cavity. Only 1% of all extracranial schwannomas show that intraoral occurrence with tongue is the commonest site and retromolar region is the least common site. It presents as encapsulated, slow growing, solitary, smooth-surfaced, usually asymptomatic tumor. We report a case of 70-year-old male with ...

A complete understanding of the feeding structures is fundamental in order to study how animals survive. Some birds use long and protrusible tongues as the main tool to collect their central caloric source (e.g., woodpeckers and nectarivores). Hummingbirds are the oldest and most diverse clade of nectarivorous vertebrates, being a perfect subject to study tongue specializations. Their tongue fu...

We report our second case of fracture of a SMART self-expandable metallic stent (Cordis Endovascular, Warren, NJ) placed to treat biliary obstruction due to an unresectable common bile duct carcinoma. An 82-year-old man presented with jaundice. Computed tomography and ultrasonography on admission demonstrated a mass in the lower common bile duct. The mass was identified as a common bile duct ob...

Schwannoma is a benign encapsulated slow-growing tumor that originates from Schwann cells of the peripheral nerve sheath. It usually occurs in the head and neck; however, it is rare in the oral cavity. The tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. We report a rare case of schwannom...

Lipoma is a rare benign tumor of adipose tissue in the oral cavity. It accounts for 1 to 4% of benign neoplasms affecting predominantly the buccal mucosa, floor of mouth and tongue. We report a case of intraoral lipoma in buccal mucosa. The clinical presentation is a painless yellowish mass. The usual lesions consist of a well circumscribed, lobulated mass of mature fat cells. In other situatio...

Lipomas are common benign soft tissue neoplasms of mature adipose tissue. Most of lipomas develop in the subcutaneous tissues but deeper tissues may be involved as well; the oral cavity is not commonly affected. The overall incidence in the oral cavity is thought to be between 1% and 4.4% of all benign oral lesions. Oral lipomas can occur in various anatomic sites including the major salivary g...

Alveolar soft part sarcoma (ASPS) constitutes a rare soft tissue malignant neoplasm comprising less than 1 % of all soft tissue sarcomas. ASPS demonstrates a strong predilection for adolescents and young adults, with a female predominance reported. The head and neck region is the most commonly affected region in pediatric patients with the tongue and orbit affected most commonly. Herein we pres...
