Lipoblastomas are benign neoplasms of white adipose which usually occupy the trunk and limbs in pediatric patients. They can seldomly involve head neck, as a lateral cervical mass. Magnetic resonance imaging is most useful modality for identifying these lesions. Treatment involves complete excision, patients followed with serial exams and/or recurrence more common neck. Here we present an excee...

Clear-cell hidradenocarcinomas are extremely uncommon sweat gland tumors with a predilection for the head and neck. In limited number of articles reporting breast involvement, primary focus concerns this entity's histological immunohistochemical characteristics. Since have potential to resemble carcinoma closely, diagnosis may be challenging. Therefore, authors report first case hidradenocarcin...

Lipomatous tumors originate from adipocytes, and represent the largest group of mesenchymal tumors. Lipomas are most likely under reported due to their insidious growth. About 13% of lipomas occur in the head and neck region. When they occur in the maxillofacial region, it is likely for the patients to be referred to the hospital for aesthetical reasons. In this multicenter study, data such as ...

Paragangliomas are tumors of the autonomic nervous system, arising from paraganglionic tissue. Paragangliomas of the head and neck region are very rare. In the head and neck, the most common sites of origin of this neoplasm are the carotid body, the jugular bulb and the vagal body. Paragangliomas of the nose and paranasal sinuses are very uncommon. The authors referred one case of nasal paragan...

The solitary fibrous tumor (SFT) is a mesenchymal neoplasm first described by Klemperer and Rabin in 1931. It involves primarily the pleura, but has been described in the urinary bladder, limbs, thorax and abdomen, lungs, kidneys, prostate, meninges, mediastinum, and head & neck. In the head and neck, this tumor may involve the orbit, salivary glands, soft tissues, eyelids, mouth and nose, naso...

Angiosarcoma of the head and neck is a rare malignant neoplasm. Approximately 50% of angiosarcomas occur in the head and neck; however occurrence of angiosarcoma in the oral cavity is extremely rare. This case report presents clinical, Computed Tomography (CT) and histopathological findings of a case of angiosarcoma of the soft palate. The malignant tumor occurred in a 56-year-old man who repor...

Squamous cell carcinoma of the head and neck (SCCHN) is the fifth most common neoplasm worldwide, with an estimated global incidence of more than 500,000 cases per annum (1). The UK incidence was 7745 cases per year in 2006 (2). SCCHN presents formidable challenges for therapeutic intervention and these are often secondary to the vulnerability of critical anatomical structures in the head and n...

Atrophy of the muscles of mastication is a well known indirect sign of damage to the mandibular division of the trigeminal nerve (V3). Because V3 motor palsy is difficult to diagnose clinically, computed tomography (CT) or magnetic resonance (MR) imaging of the head and neck often provide the only evidence of masticator space muscle atrophy (1). This finding, in turn, should alert the physician...
