In recent years, transoral robotic surgery (TORS) has been used for the removal of pharyngeal and laryngeal cancers with the objective to improve functional and aesthetic outcomes without worsening the survival. This prospective single-centre cohort study described TORS in selected tumours of the tongue base in order to assess safety, efficacy and functional outcome of the procedure. From Octob...

Pleomorphic adenoma also known as “mixed tumor” is the most common neoplasm in major salivary glands. It is a benign tumor arises from the parotid gland in 84% of cases and represents 45% of parotid gland tumors [1]. Only 6.5% are found in the minor salivary glands [2]. Salivary gland tumors occurring in ectopic sites are rare and poorly understood; sometime we can find heterotopic tissue arisi...

Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been pres...

GCT is a rare neoplasm and usually shows the benign character. GCT can occur in any body site and may be multifocal. The most common involved site is tongue which accounts for nearly 30% of all cases but skin and subcutaneous tissue are also affected frequently. Breast is an unusually involved site and accounts for 6% of all GCTs. The histiogenesis of GCT is still controversial but further inve...

Granular cell tumor (GCT) was first described by Abrikossof in 1926. This tumor is a benign neoplasm of unclear histogenesis that is generally believed to be of nerve sheath origin. GCT is not common and most often affects the tongue, skin, and soft tissue, although it may occur anywhere in the body. Gastrointestinal tract involvement, and especially that of the colon, is very rare. This usuall...

econstruction of the mandible presents unique challenges to the head and neck surgeon. Although mandibular defects can result from trauma, infection, congenital deformities, or osteonecrosis, it most commonly occurs following ablative surgery for the treatment of benign or malignant neoplasms. Primary intrabony mandibular carcinoma is rare; therefore, the involvement of the lower jaw is usually...

Diffuse large B-cell lymphoma (DLBCL) is a primary malignant B-cell lymphoid neoplasm. The bulk of the disease develops in the Waldeyer ring (palatine tonsils, nasopharyngeal adenoids, base of the tongue, and lingual tonsils). DLBCL accounts for more than 50% of all Waldeyer ring lymphomas, which in turn account for about 15% of all head and neck lymphomas and about 50% of all extranodal head a...

Adenoid cystic carcinoma is a rare neoplasm commonly originating from the minor salivary glands. The clinical findings typical of this tumor include slow growth, perineural invasion and high frequency of local recurrence. In this study, a patient presented with a tongue base lesion that was treated with surgical excision and additional postoperative external beam radiotherapy. However, local re...

background: clinical and epidemiological variation was seen between the colon cancer (cc) and rectum cancer (rc). so, there is not so much data available about the epidemiological and clinicopathological differences and prognostic factors regarding to cc and cr in iran, we aimed to perform this study. methods: all cases of cc and rc referred to oncology and gastroenterology wards of taleghani g...
