Parotid swelling is a common presentation in ENT clinic. Most of the cases involve pathology of the gland. There are not many reported cases about parotid duct pathology. We describe a case of a large parotid duct mucocele with a calculus. Excision of the mucocele and superficial parotidectomy was performed. The post-operative recovery was uneventful.

OBJECTIVE Assessment of benign and malignant lesions of the parotid gland, including metastatic lesions, is challenging with current imaging methods. Fluorine-18 FDG PET/CT is a noninvasive imaging modality that provides both anatomic and metabolic information. Semiquantitative data obtained from PET/CT, also known as PET/CT parameters, are maximum, mean, or peak standardized uptake values (SUV...

Background Lipoblastomas are rare benign neoplasms that arise from fetal white fat cells. They are typically found in children under the age of 3 and have been reported in the mediastinum, extremities, and infrequently in the head and neck. We present a rare case of a lipoblastoma arising from the parotid gland and the first known report of a parotid lipoblastoma in a teenager. Case presentat...

1. The liberation of ammonia from adenosine 5'-phosphate (AMP) and adenosine and the release of inorganic phosphate from AMP were investigated in homogenates of bovine and human parotid glands. 2. Adenosine phosphate deaminase (AMP deaminase) was purified from bovine and human parotid glands. The enzyme preparations obtained were free from adenosine deaminase and 5'-nucleotidase activities. 3. ...

Deoxyribonucleic acid (DNA) was extracted from parotid gland tumors with phenol. The injection of this DNA into 24-hour to 1-week-old AKR mice resulted in a 65 per cent incidence of parotid tumors and/or epithelioid thymomas. Oncogenic properties of the DNA preparation were abolished by incubation with deoxyribonuclease. Cell-free filtrates of the parotid tumors inoculated into suckling AKR mic...

ABSTRACT OBJECTIVES To find preoperative predictive signs for better surgical planning of the facial nerve in parotid tumors. METHODS Prospective study in patients with primary parotid malignancies. Patients with primary parotid malignant tumor were investigated for preoperative clinical signs in correlation with histological findings and surgical management of the facial nerve. OUTCOMES...

UNLABELLED Parotid gland parenchyma histology may be altered by local or systemic, pathological or nonpathological conditions. OBJECTIVE This paper aims to highlight the fatty degeneration of the parotid gland, a not well-known non-pathological condition. METHOD In a retrospective study, we collected a series of 6 patients which presented a swelling of the parotid, but even after extensive ...

Metastatic malignancy presenting as cardiac tamponade is not uncommon; however, hematogenous spread from carcinoma is rare. There are only three previously reported cases of parotid malignancy with pericardial metastasis. We report a case of parotid adenocarcinoma leading to cardiac tamponade in a 61-year old man. The patient presented with signs and symptoms of cardiac tamponade. The diagnosis...

Facial nerve palsy is usually associated with a malignant parotid neoplasm; it is highly unusual for it to result from a benign situation, such as inflammation or infection of the parotid gland. Surgery along with prompt medical treatment is the mainstay, and in the majority of the patients, nerve paralysis recovers in the follow-up period. We report a case of a 50-year-old non-diabetic non-hyp...
