Warthin tumor is a well-defined benign salivary gland neoplasm consisting of both epithelial and lymphoid components. The tumor is the second most common benign tumor next to pleomorphic adenoma. We present a case of adenocarcinoma, not otherwise classified, arising in unilateral Warthin tumor of the parotid gland in a 63-year-old male patient. Carcinomas arising in or from the ...

Pleomorphic adenoma also known as “mixed tumor” is the most common neoplasm in major salivary glands. It is a benign tumor arises from the parotid gland in 84% of cases and represents 45% of parotid gland tumors [1]. Only 6.5% are found in the minor salivary glands [2]. Salivary gland tumors occurring in ectopic sites are rare and poorly understood; sometime we can find heterotopic tissue arisi...

Acinic cell carcinoma (ACC) is an uncommon salivary gland neoplasm that generally displays an indolent growth pattern. Most cases arise in the major glands, particularly the parotid. However, it can arise from minor salivary glands in the oral cavity and aero-digestive tract. Although ACC is generally a low-grade malignant tumor, poorly differentiated and high-grade transformed variants exhibit...

Pleomorphic adenoma or benign mixed tumor is the most common salivary gland tumor. It is most frequently located in the parotid gland, and is considered to be a benign neoplasm accounting for 70-80% of all benign tumors of the salivary glands [1]. Benign metastasizing pleomorphic adenoma is extremely rare, with only a handful of cases described. We report a case of a histologically benign mixed...

Myopericytoma (MPC) is a vascular neoplasm exhibiting differentiation towards perivascular cells. Variable cytoarchitechtural features are visible within MPC, and there is much overlap between MPC, myofibroma and glomus tumours. MPC have a local recurrence rate of 10-20% and malignancy has been described in a few published cases. Previously, superficial parotidectomy has been recommended for MP...

Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely inv...

Sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have been reported thus far in addition to the two new cases of sialolipoma arising in the major salivary glands in this study. Thirty-six cases of sialolipoma published in English language reports were analyzed considering...

Pleomorphic adenoma is the commonest type of all benign and malignant salivary gland neoplasm majority involving the parotid gland. It is a slow growing and benign tumour which can reach an enourmous size and may turn malignant if left untreated. Although uncommon, most cases of giant pleomorphic adenoma were reported before 1980’s, with few publications recently. This paper presents a rare cas...

OBJECTIVE To delineate the spectrum of salivary gland tumors in our setup. SETTING The Aga Khan University Medical Centre, Karachi. METHOD Tumors were analysed considering histological type, age and sex of the patients and anatomic location. The diagnosis of individual tumours was based on the 1991 World Health Organisation Classification. RESULTS During the span of eight years (1991-1998...

Carcinosarcoma ex pleomorphic adenoma is a rare malignant neoplasm, with most cases reported in the parotid gland. We herein report case of 75-year-old male referred to our hospital long-standing right lesion that was treated an outside by superficial parotidectomy. The patient painful, rapidly enlarging mass following excision. Histopathological examination showed proliferation epithelial and ...
