A 57-year-old woman was first seen in the ENT clinic of Osaka University Hospital with a complaint of recent enlargement of a painless mass at the right parotid region of 35 years' duration. A smooth surfaced, elastic mass of about 5 × 6cm was palpated at the right subauricular area extending to the submandibular region. The mass was not adhered to the skin.

BACKGROUND The fissures of Santorini have long been known as a gateway for disease to pass from the external auditory canal to the periparotid and neck spaces. Although anatomically understandable, description of disease that originates in the parotid gland and extends through the fissures to the external auditory canal is rare. This is, in fact,the first presentation of such a patient at our i...

BACKGROUND AND PURPOSE Weak or absent CT enhancement in pleomorphic adenomas of the parotid gland has been observed immediately after i.v. contrast administration. This feature can result in poor lesion conspicuity relative to both normal parotid tissue and other parotid abnormalities. The purpose of this study was to document the delayed CT enhancement characteristics of parotid pleomorphic ad...

Lipomas are common benign tumors usually detected on the torso, neck, upper thighs, and upper arms. However, they are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. This report describes a rare case of a lipoma in the superficial lobe of parotid gland. A 71-year-old female patient adm...

PURPOSE To revisit and reintroduce sialography as an important tool for the assessment and diagnosis of salivary gland obstruction. PATIENTS AND METHODS A sample of 30 consecutive patients undergoing sialography was selected. Parotid sialography was performed in 22 patients (12 females and 10 males). The patients undergoing parotid sialography presented with bilateral or unilateral enlargemen...

Objectives: Hemangiomas account for 0.4%-0.6% of all tumors of the parotid gland and are extremely rare in adults. Changes in blood flow dynamics within hemangiomas result in thrombus formation and phleboliths. We present a case of cavernous hemangioma with multiple phleboliths of the parotid gland masquerading assialolithiasis in an adult patient. Methods: A 43-year-old woman visited our hospi...

OBJECTIVES/HYPOTHESIS Lymphoma of the parotid gland (LPG) is a rare disease. Clinical diagnosis is difficult, due to a lack of specific symptoms and findings. The aim of this study is to evaluate the diagnostic workup based on the analysis of our cases of LPG and to present the stage-dependent treatment outcome. STUDY DESIGN Retrospective case-control study. METHODS From 1992 to 2008, 697 p...

Introduction: Salivary gland cancer is an uncommon malignancy in the head and neck. The most common histopathologic type salivary malignancies mucoepidermoid carcinoma (MEC). Radiotherapy has a role malignancy, especially inoperable cases postoperative settings. Definitive or radiotherapy with without chemotherapy can improve locoregional control (LRC) patients parotid carcinoma. Case Presentat...

We report a case of a Calcium pyrophosphate dihydrate deposition disease (CPPD) presenting as a mass in the parotid and temporomandibular joint (TMJ) that simulated a parotid tumor. A 35 year-old man presented with pain in the left ear area. A CT Scan of the area showed a large, calcified mass surrounding the left condylar head, and extending into the infratemporal fossa. FNA of the mass showed...
