Introduction  Squamous cell carcinoma is the most common malignancy of the head and neck, with the buccal mucosa being the most common site involved. Early locoregional metastasis is a hallmark of this disease, and early stage tumors may harbor metastatic nodes that are occult. Certain parameters can help identify high-risk patients for whom the pattern of occult nodal metastasis can be predict...

Urethroplasty may involve the use of tissue substitution including buccal mucosa graft (BMG), penile fasciocutaneous flaps, or skin grafts. Stricture recurrence and fistula formation are some uncommon complications that can result from surgery. The development of squamous cell carcinoma (SCC) after BMG substitution urethroplasty is a new complication that we encountered that has not been descri...

UNLABELLED Vascular lesions have been classified in two broad categories, hemangiomas and malformations. Encapsulated vascular lesions have not been reported in the oral cavity, but they were described in other sites, mainly in the orbit. Herein, we present a case of an oral encapsulated vascular lesion located in the right buccal mucosa of a 69-year-old male, including histological and immunoh...

Collagen fibre organisation and fibril size were studied in the buccal gingival and hard palate mucosa of Macacus rhesus monkey. Light and electron microscopy analysis showed connective papillae exhibiting a similar inner structure in the different areas examined, but varying in distribution, shape and size. Moving from the deep to surface layers of the buccal gingival mucosa (free and attached...

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...

OBJECTIVE To compare the degree of keratinization of buccal mucosa between nonsmoking menstruating and postmenopausal women without oral complaints whose iron status was established. STUDY DESIGN Samples collected from 26 nonsmoking, regularly menstruating women (mean age, 26 years) and 18 nonsmoking, postmenopausal women without oral complaints (mean age, 57 years) were stained according to ...

Reconstruction of long-segment tracheal defects requires a vascularized allograft. We report successful tracheal allotransplantation after indirect revascularization of the graft in a heterotopic position. Immunosuppressive therapy was administered before the operation, and the tracheal allograft was wrapped in the recipient's forearm fascia. Once revascularization was achieved, the mucosal lin...

Resection of buccal mucosa tumors may occasionally involve the labial angle and peripheral skin. Reconstruction is required when the resection involves more than one-third of the lip. We describe a single-stage reconstruction using a facial artery musculomucosal (FAMM) flap and a vermilion advancement flap after buccal mucosa resection including the labial angle. A 62-year-old woman with carcin...

Mucoadhesion can be defined as a state in which two components, of which one is of biological origin, are held together for extended periods of time by the help of interfacial forces. Among the various transmucosal routes, buccal mucosa has excellent accessibility and relatively immobile mucosa, hence suitable for administration of retentive dosage form. The objective of this paper is to review...

    Background: Azo is a synthetic dye used in batik industries. It can be toxic to the tissue when exposed via inhalation, swallowing, or direct contact. Expression of cytokeratin will change in hyperplastic and cancer of the oral mucosa. Expression of Cytokeratin 8, 18, 19 is strong in the epithelial cells that undergo excessive hyperproliferation and oral mucosal changes in le...
