Purpose: Basal cell adenoma of the salivary gland is an uncommon type of monomorphic adenoma. The most frequent location is parotid gland. It usually appears as a firm, mobile and slow-growing mass. Originally the term "basal cell adenoma" is described as a benign salivary gland tumor comprised of uniform appearing basaloid cells which are arranged in solid, trabecular, tubular, and membranous patterns. But the myxoid and chondroid mesenchymal like component as seen in pleomorphic adenoma is lacking in basal cell adenoma. We report a case of basal cell adenoma of parotid gland with review of the literatures. Methods: The 59-year-old female patient was referred to our department with a painless palpable mass in the left preauricular region for about 1 year. Movable and nontender subcutaneous mass was palpable. There was no evidence of cervical metastasis in computed tomography and ultrasonography. On fine needle aspiration cytology, pleomorphic adenoma was suspected. Under general anesthesia, superficial parotidectomy including tumor was performed. The biopsy result was basal cell adenoma. Results: Long-term follow-up for 54 months showed favorable result without evidence of recurrence except for temporary facial nerve weakness right after the surgery. Conclusion: Basal cell adenoma is the third most frequent benign tumor of the salivary gland, following pleomorphic adenoma and Warthin's tumor, although the incidence is low. The typical clinical feature of the basal cell adenoma is slowly growing, asymptomatic, and freely movable parotid mass. Basal cell adenoma should be also considered as a differential diagnosis of the parotid gland benign tumor.

Pilomatrixoma is an uncommon tumor arising from hair follicles. Commonly occur in children and most frequently in the head and neck region. It can be mistaken for parotid gland tumor, dermoid cyst, or epidermoid cyst, especially when large lesions develop over the periauricular area, difficulty discerning them from lesion developing within the superficial lobe of the parotid gland may occur. We experienced two cases of pilomatrixomas mimicking parotid gland tumor. Although their histologic appearance is characteristic, they may be clinically misdiagnosed. However, combining clinical information with the distinct histologic features should lead to the correct diagnosis.

Angiosarcoma is a rare and highly malignant neoplasm which develops from the endothelium of blood vessels. A few cases of primary angiosarcoma of the parotid gland have been reported. However, there is no report of primary angiosarcoma of the accessory parotid gland. In this case, we report a primary angiosarcoma of the accessory parotid gland in a 45-year-old man with growing cheek mass. Ultrasonography revealed a $2.0{\times}2.6cm$ sized homogeneous hypoechoic mass and computed tomography showed a contrast enhanced homogeneous mass. Fine needle aspiration biopsy suggested a benign tumor. The mass was completely excised with a minimal vertical incision. The histopathology showed anastomosing vascular channels lined by atypical endothelial cells and many branching vessels with staghorn appearance with positive immunohistochemical staining for CD34, a highly specific endothelial marker. The patient underwent postoperative radiotherapy and was followed for 8 years without recurrence and metastasis.

이하선에 발생한 지방종은 과거에 적절한 진단방법의 부재와 낮은 발생빈도로 인하여 종종 양성혼합종이나 와르틴종양으로 진단되어 종물을 포함하는 이하선을 절제하여 왔다. 하지만 진단방법의 발달로 전산화단층촬영이나 자기공명영상을 통하여 술전에 지방종의 진단이 가능해져 다른종양들과 감별되므로 이하선의 실질을 보존하며 종물을 제거하는 것이 용이하게 되었다. 본증례에서는 이하선 천엽에 발생한 지방종을 전산화단층촬영을 통하여 진단하고 이하선절제술을 시행하지 않고 이하선의 실질의 손상을 최소화하며 종양을 제거하였다. 술후 3개월 후에 방사선 동위원소를 이용한 이하선의 기능검사를 통하여 이하선의 정상적 기능을 확인하였다.

Dermoid cysts are developmental anomalies that represent the simplest form of teratoma. They are the result of the sequestration of the skin along the lines of embryonic closure. These cysts of the head and neck are uncommon and account for 7% of all dermoid cysts. They are predominantly found in the orbit, floor of mouth, and nose. As a dermoid cyst of the parotid gland is extremely rare, it is often misdiagnosed preoperatively. By way of imaging modalities such as computed tomography, MRI and ultrasongraphy along with FNAB, it can be differentiated from many other cystic lesions of the parotid gland. We report a case of dermoid cyst of the parotid gland which masqueraded as lipoma before complete surgical excision.

Solitary fibrous tumors are commonly arise in the pleura and less commonly in extrapleural sites. In head and neck area, solitary fibrous tumors can occur in nose, paranasal sinus, soft palate, epiglottis, thyroid, parotid and submandibular gland. To our knowledge, this is the 5th case of solitary fibrous tumor arising from the parotid gland in English literature. We report a case of solitary fibrous tumor occurred in the superficial lobe of right parotid gland which was successfully treated by superficial parotidectomy with preservation of the facial nerve.

In branchial lymphoepithelial cyst (BLEC), which is also known as branchial cleft cyst, the remnants of a branchial arch develop into a cyst, causing swelling. The first case of BLEC in the parotid gland was reported by Hildebrant in 1895. Since then, BLEC in the parotid gland has continued to be reported, but in rare cases. A 45-year-old man presented to our hospital with a swelling of the left cheek of approximately 6 months' duration. The patient underwent a superficial parotidectomy and was pathologically diagnosed with BLEC. Of note, this was the first case of non-human immunodeficiency virus (HIV)-related BLEC of the parotid gland in South Korea. BLEC is a benign condition, but its treatment depends on the presence of HIV infection. In HIV-negative patients, BLEC does not require a further work-up to evaluate metastasis. Our case report describes the diagnosis and treatment of BLEC in a patient without HIV.

Intraductal papilloma is an extremely rare benign tumor especially when it arises from major salivary gland. Recently, we experienced a case of an intraductal papilloma arising from the parotid gland in a 51-year-old woman. The radiologic finding showed lobulated enhancing and cystic solid mass in the left parotid superficial lobe. Superficial parotidectomy was performed. Pathological findings showed papillary proliferations with fibrovascular cores lined with bland cuboidal or columnar epithelial cells, and immunohistochemical stain results were consistent with intraductal papilloma. We report a case of intraductal papilloma in parotid gland with a review of literature.

Purpose: Primary malignant lymphomas of the salivary glands are uncommon, representing only 1.7% to 3.1% of all salivary neoplasms and 0.6% to 5% of all tumors and tumor-like lesions of the parotid gland. Lymphomas of the parotid glands are usually manifestations of a systemic disease process but primary lymphomas of the parotid glands are rare. Most of these lesions are classified as extranodal non-Hodgkin's lymphoma. We report the clinicopathological features of primary malignant lymphoma of the parotid gland based on an analysis of our cases. Methods: The subject was a 48-year-old male patient with a malignant lymphoma originating in the parotid gland, which had been slowly increasing in size over previous 6 months. The diagnosis was established by MRI and a superficial lobectomy. After diagnosis, the patient was referred to an oncologist for staging and medical treatment. Results: The stage was IIIA. The patient was treated with chemotherapy following surgery with rituximab and CHOP (Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). The tumor was controlled successfully by chemotherapy. The patient was followed up for 1 year with no relapse. Conclusion: A case of primary non-Hodgkin's lymphoma of the parotid gland was treated with a superficial parotidectomy and chemotherapy. The disease was well controlled after a 1 year follow-up.
