INTRODUCTION Acinic cell carcinoma is a rare form (2-4%) of parotid tumor. It is, however, the most frequent form of bilateral parotid tumor and the second most frequent form in children. CASE REPORT A 22-year-old man had several years' history of left parotid tumor, discovered to be acinic cell carcinoma. MRI found a synchronous contralateral tumor of the same histologic nature. DISCUSSION...

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...

We herein describe a case of accessory parotid gland tumor, including diagnosis and surgical approach. The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct empting into the Stensen's duct. The accessory parotid gland exists in 21-61 % of individuals. However, the appearance of an accessory parotid tumor is rare,...

Warthin’s tumor, also known as papillary cystadenoma lymphomatosum or adenolymphoma, is the second most common benign tumor of the salivary glands. It arises exclusively in lower part of the parotid gland and affects mainly male in sixth or seventh decades of life. Studies have shown that there is a close association between Warthin’s tumor and cigarette smoking. Preoperative fine needle aspira...

OBJECTIVE Facial nerve preservation and oncological safety are crucial in surgery of parotid tumors. An unexpected histopathologic diagnosis of a malignant parotid tumor, however, may unfavorably require a second, more radical surgery. The aim of this study was to find out whether the assessment of serological tumor markers in parotid saliva might have some diagnostic significance in the preope...

Sialolipoma is a rare benign neoplasm and was recently described as a histological variant of intraoral lipoma. In the current report, the case of a of a 65-year-old female with a slow-growing mass in the right parotid gland with recurrence is presented. The initial clinical diagnosis was a benign salivary gland tumor. The tumor was situated between the right parotid gland and the right massete...

Acinic cell carcinoma arising in salivary glands is a rare tumor, accounting for 2% to 5% of the primary neoplasms of the parotid gland. When these tumors are well-differentiated, the neoplasia has innocuous aspect, due to the similarity to normal parotid tissue. This makes the diagnosis difficult. Initially the malignancy of this tumor was uncertain; however, recent studies have declared it as...

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...
