Salivary gland tumors account for 3 to 6% of all head and neck neoplasms in adults. Some 70 to 85% of these lesions are found in the parotid. Carcinoid tumors, which represent a distinct and relatively uncommon subset of neuroendocrine tumors, are most commonly found in the gastrointestinal tract, although in rare cases they are known to occur in extragastrointestinal locations, including the l...

The antibody response of Macaca fascicularis in parotid saliva and serum to local immunization by two routes with Streptococcus mutans was studied and compared over 1 year. Antibodies were titrated and classified by indirect immunofluorescent staining using specific antiglobulin conjugates. Antiglucosyltransferase activity was assayed by an enzyme inhibition test. Animals were immunized first b...

Post-traumatic parotid sialocoele is a subcutaneous extravasation of saliva from the parotid gland secondary to traumatic disruption of its duct or parenchyma. Currently, there is no consensus regarding the best therapy for parotid sialocoele, as it is resistant to conservative management. The present paper puts forward a relatively simple, safe and effective technique for the treatment of paro...

Intra-parotid dermoid cysts are extremely rare. Clinically, they present like any other parotid lump and pre-operative diagnosis is rarely possible. A 62 years old Caucasian man presented with a painless lump in his right parotid region. The Magnetic Resonance Imaging (MRI) scan revealed a 3 x 3 cm mass in the parotid tail. Cytological examination was unhelpful. The patient underwent successful...

A 57-year-old man presented with a 16-month history of right parotid swelling since undergoing a transoral sialolithotomy of the parotid duct. An ultrasound and a computed tomography scan showed a 6 cm-long dilated parotid duct without evidence of sialolithiasis or tumor mass. The complete Stensen's duct stenosis that was found was managed by a surgeon-performed ultrasound-guided transfacial ne...

Parotid gland or duct injury can be caused by assault with a knife, bottle, or more rarely, gunshot. Post-traumatic parotid gland and duct injuries are not common.The low rate of occurence of parotid injury may account for the missed diagnosis of parotid and duct injury on admission and, after a varying period, sialoceles or fistulas. This report describes a case of a post-traumatic sialocele o...

Introduction: The parotid gland is the most common site for salivary gland tumors. 70-80% of salivary gland neoplasms occur in the parotid gland, of which 80% are benign, 20% are malignant of which 80% of the benign tumors are pleomorphic adenomas. Aims and Objectives: (1) To know the incidence of parotid gland tumors with respect to age and sex. (2) To study the various modes of clinical prese...

1. Rabbit antisera to purified rat parotid alpha-amylase were prepared. 2. The relationships between rat parotid-gland, pancreatic, serum and liver amylase were investigated by using the antisera in immunodiffusion, immunoelectrophoresis and immunoinhibition experiments. 3. Serum and liver amylase were identical, and very similar to parotid-gland amylase; pancreatic amylase was, however, quite ...

Abstract Background Pilomatrixoma is a rare benign tumor of the hair follicle. It more common in children and women. The cervical facial region are most frequent location for this type tumor. Due to its variable clinical presentations, it can sometimes be misdiagnosed as malignant surrounding tissues, described our case. diagnosis confirmation pathological. Case presentation We report case 34-y...

Congenital absence or rudiment major salivary glands, especially of the parotid glands, are a rare entity. Aplasia of parotid glands has been described alone or in association with abnormalities of other salivary glands, first branchial arch developmental disturbances and other congenital anomalies such as lacrimoauriculodentodigital syndrome, mandibulofacial dysostosis and ectodermal dysplasia...
