BACKGROUND Mucoepidermoid carcinoma of salivary glands usually metastasizes to the lungs, liver, bone, brain, and skin. We report a rare case of distant metastasis of high-grade mucoepidermoid carcinoma of the parotid to the ipsilateral bulbar conjunctiva of the eye. CASE PRESENTATION Sixty-year-old male of Kashmiri origin presented to our tertiary care referral cancer institute with exophyti...

Pleomorphic adenoma of the parotid gland with metastases to the liver is a rare etiology of focal liver lesions, and there are no described pathognomonic imaging features. We report a patient who presented with a newly diagnosed rectal cancer and multiple cystic liver lesions suspicious of mucinous synchronous liver metastases. Following chemotherapy no reduction in the number or size of the li...

BACKGROUND Salivary ductal carcinoma (SDC) of parotid gland is a rare and aggressive entity; accounting for 1-3 % of all malignant salivary gland tumors, 0.2 % of epithelial salivary gland neoplasms, 0.5 % of salivary gland carcinomas, and 1.1 % of parotid gland carcinomas. Here in we aimed to evaluate the clinico-pathological features and treatment outcomes of parotid gland SDC in Saudi popula...

BACKGROUND Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. The aim of this study was to determine geometric changes of parotid glands as function of...

Adenocarcinoma no otherwise specified (NOS) and polymorphous low-grade adenocarcinoma (PLGA), are malignant tumors of the salivary glands. Both types have potential for recurrence distant metastases. Rare cases metastases lead to absence standardized systemic therapy gland cancer. This case report aims expand literature regarding parotid adenocarcinoma. We a 54-year-old woman who complained rec...

BACKGROUND Orbital metastases are an uncommon finding, being present in just 9% deceased patients with metastatic cancer. Only a quarter of patients with choroidal metastases have bilateral disease. Parotid cancer is not a common form of head and neck malignancy. Bilateral multifocal metastases from adenocarcinoma ex pleomorphic of parotid gland have been documented just once before in the lite...

BACKGROUND This study was carried out to evaluate tumor recurrence following extracapsular dissection of pleomorphic adenomas of the parotid gland. METHODS We conducted a retrospective evaluation and clinical follow-up of the patients who underwent extracapsular dissection of a pleomorphic adenoma as primary surgery in the otolaryngologic department of the Erlangen University Clinics during t...

Introduction To observe the changes in the patients anatomy and the effects of these differences on dose distribution throughout the treatment in order to design an optimal adaptive plan and to find the optimal time for replanning in head and neck cancer patients who receive primary radiotherapy or chemoradiotherapy. Materials and Methods Fifteen head and neck cancer patients were evaluated pro...

PURPOSE To concurrently quantify the radiation-induced changes and temporal evolutions of parotid volume and parotid apparent diffusion coefficient (ADC) in nasopharyngeal carcinoma (NPC) patients treated by intensity-modulated radiotherapy by using magnetic resonance imaging (MRI). MATERIALS AND METHODS A total of 11 NPC patients (9 men and 2 women; 48.7 ± 11.7 years, 22 parotid glands) were...
