Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely inv...

A case of epithelial myoepithelial tumour originating from the tracheal gland in a 57 year old woman is described. The tumour was removed by segmental tracheal resection and end-to-end anastomosis. Histologically, the tumour comprised clear cells and presented a monophasic pattern. Immunohistochemical analysis showed that the tumour cells were positive for both S-100 protein and smooth muscle a...

Patients with salivary gland disease most frequently present with complaints of oral dryness, swelling, or a mass in a gland. This chapter first reviews briefly the anatomy and physiology of the salivary glands and then outlines a diagnostic approach to the patient who has signs and symptoms that are suggestive of salivary gland dysfunction. The examination of a patient with dry mouth is descri...

Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region. Occurrences in the head and neck are mostly detected in the major salivary gland, oral cavity, pharynx and paranasal sinus...

PURPOSE We report two new cases of chondroid syringoma (CS) of the eyelid. Until 1961, this entity was known as pleomorphic adenoma or benign mixed tumour of the skin of salivary glands type. This tumour occurs most commonly in the head and neck regions. CASE REPORTS We describe two cases of CS with rapid growth, in the upper right eyelid, with no relation with the palpebral lobe of the lacri...

Salivary gland tumors are rare and account for 2-3% of tumors occurring in the head and neck. Pleomorphic adenoma is a benign neoplasm which is commonly encountered in the parotid gland and other major salivary glands. At times they can also develop in minor salivary glands of the palate. The majority of minor salivary gland tumors are malignant. This case report describes a case of mixed tumor...

Neoplasms of the major and minor salivary glands are morphologically and a clinically diverse group of neoplasms which lead the clinician to diagnostic and management challenges. This article aims to report a case of mucoepidermoid carcinoma in 83 - year - old woman who presented in the dermatology clinic with a tumour mass in the left auricular area.

Although parotid gland involvement with tuberculosis is the most common among salivary glands tuberculosis, tuberculous parotitis is rare. Parotis tuberculous is clinically indistinguishable from a parotid tumour and also diagnostic techniques may fail to reveal the diagnosis. We have been presented two cases with diagnosis of parotid gland involvement with tuberculous. We made fine needle aspi...
