Cutaneous adenoid cystic carcinoma (CACC) is an extremely rare neoplasm of head and neck region, and is characterized by propensity for local recurrence and perineural invasion. Late distant metastases occur usually to lungs. Although patients with lung metastases from CACC cannot be cured, long-term survival may be possible due to its slow-growing malignancy. We report a case of a 69-year-old ...
Salivary gland tumours represent approximately 3% of all head and neck tumours. Warthin’s tumour, also known as Papillary cystadenoma lymphomatosum (PCL), is the second most frequent benign salivary gland neoplasm usually found in the superficial lobe of the parotid and is strongly associated with smokers. Here, we report a classical case of Warthin’s tumour of ten years duration in a 52year-ol...
Schwannoma (neurilemmoma) is a benign neoplasm originated from the neural sheath and occurring most frequently in the head and neck. Intraosseous schwannomas are rare. The mandible is the most common site of occurrence for these lesions. This article reports the case of an intraosseous schwannoma located in the mandibular symphysis of an 11-year-old boy. The lesion was surgically removed and no...
Background and aim: Head and neck cancers are the tenth most common cancers worldwide. Since these cancers can cause severe complications and mortality, early diagnosis and investigation of their prevalence in various regions may be life-saving. Therefore, this study evaluated the prevalence of head and neck cancer over a 10-year period in Gilan province, Iran. Materials and methods: This is a...
Solitary fibrous tumor (SFT) was first described in the pleura by Lietaud in 1767; later in 1870, Wagner described the localized nature of this type of tumor and Klemperer and Rabin classified pleural tumors into two types: diffuse mesotheliomas and localized mesotheliomas. Recent years have seen the redefinition of this neoplasm, due to better technology; it is now proven that this neoplasm ma...
Overall salivary gland tumours are rare, comprising of less than 3% of overall head and neck neoplasms. Parotid gland is the most common site for the benign salivary gland neoplasm. Usually they are painless slow growing lesion involving the superficial or deep part of the gland and can severely affect the facial nerve functioning. Treatment mainly comprises of surgical excision with preservati...
S19 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 2.7 ± 1.7 cm. Most patients were asymptomatic. The type of cystic lesions was intraductal papillary mucinous neoplasm (IPMN; n = 35), serous cystadenoma (n = 18), mucinous cystic neoplasm (MCN; n = 12), solid pseudopapillary epithelial neoplasm (SPEN; n = 9), cystic degeneration of other tumors (n = 4), simple cyst (n = 4), infec...
Background: Office workers spend a long period of time behind a computer during working hours. The relation between the posture of sitting during work with computer and neck pain is still debatable. Even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the FHP (forward head posture) has not always been associate...
Modern head and neck imaging has led to advances in both the diagnosis and treatment of head and neck cancers. Both computed tomography (CT) and magnetic resonance imaging (MRI) studies provide important information about the location and extent of neoplasm, particularly with respect to the interface of tumor with bone, fat, muscles and other soft tissues, air, blood vessels, dura, and brain. C...
Rhabdomyosarcoma (RMS) is a rare malignant soft tissue neoplasm comprised of cells derived from the primitive mesen¬chyme. About 35% of RMS arises in the head and neck, are are classified as parameningeal and non-parameningeal forms. These are the most common soft tissue sarcoma of the children, adolescents and young adults. Their etiopathogenesis and its molecular relevance have been emphasize...
