BACKGROUND Pleomorphic adenoma in the parapharyngeal space either occurs de novo or as an extension from the deep lobe of the parotid gland. CASE PRESENTATION A rare synchronous occurrence of pleomorphic adenoma in the parapharyngeal space and submandibular gland of a 48-year-old Nigerian male is reported. CONCLUSION Pleomorphic adenoma concurrent in the parapharyngeal space and submandibul...

Myoepithelioma (ME) is a benign tumor, arising predominantly from major and minor salivary glands (SG). Clinically, it presents as painless mass with slow growth. In our case report, this lesion occurred in 51-year-old man, presented well-defined oval on the right parotid region. The magnetic resonance imaging study confirmed presence of features that was excised surgically by partial superfici...

Background: Salivary gland tumors (SGT) are rare lesions with uncertain histopathology. One of the major signaling pathways that participate in the development of several tumors is protein kinase A. In this pathway, glycogen synthase kinase β (GSK3β) and cAMP responsive element binding protein (CREB3) are two genes which are supposed to be down regulated in most human tumors. The expression lev...

Pleomorphic adenoma usually occurs in the salivary glands but rarely in the trachea or bronchi. A 71-year-old man had abnormal shadows on a chest X-ray. Chest CT revealed one tumor in the right basal segment of the lung and another, in the left main bronchus. Bronchoscopic biopsy of the right tumor revealed well-differentiated squamous cell carcinoma. Right lower lobectomy and lymph node dissec...

Pleomorphic adenomas originating from the minor salivary glands are rare in the nasal cavity. Total surgical excision is the preferred treatment for pleomorphic adenomas. Lateral rhinotomy, midfacial degloving, transpalatal surgery and endoscopic surgery are among the surgical approaches. Endoscopic tumor removal produces less morbidity, reduces blood loss during surgery, decreases hospital sta...

Basal cell adenocarcinoma (BCAC), a salivary gland tumor, has been theorized to originate either from monomorphic adenomas undergoing a malignant transformation or to arise de novo. Here we present the first case report of a BCAC tumor that arose within a pleomorphic adenoma.

We report a case of pleomorphic adenoma of the nasal septum in a 66 year-old male. The tumor was treated by subperichondral excision. The tumor was analyzed and guidelines for its clinical and histological (immunohistochemical) diagnosis and treatment are established.

OBJECTIVE The purpose of our study was to determine useful CT criteria for differentiating serous oligocystic adenomas of the pancreas from other similarly presenting neoplasms, such as mucinous cystadenoma and intraductal papillary mucinous tumor of the branch duct type. MATERIALS AND METHODS Forty-one patients with histologically confirmed macrocystic neoplasms of the pancreas were enrolled...

UNLABELLED A history of a recent rapid increase in long-standing swelling mass was presented in the right parotid gland of an 85-year-old male. The inadequate cytologic specimens contained few small clusters of three-dimensional malignant epithelial cells having hyperchromatic pleomorphic nuclei and prominent nucleoli, adjacent to a cluster of benign monomorphic myoepithelial cells. We first in...

BACKGROUND AND PURPOSE Pleomorphic adenoma is the most common parotid neoplasm. It has a relatively high rate of recurrence after surgery. Imaging features of recurrent parotid pleomorphic adenoma have been infrequently reported in the radiology literature. In the present study, we reviewed our institutional experience with imaging of recurrent parotid pleomorphic adenomas. MATERIALS AND METH...
