Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of these tumors occurs in the minor salivary glands. especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, and obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic exarnminations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic exarnminations, dark-stained, small uniform basaloid cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

Salivary duct carcinoma (SDC) is a rare primary salivary gland malignancy characterized by histological features similar to those of ductal carcinomas of the breast. It is regarded as a high-grade malignancy associated with frequent local recurrences and early distant metastases that require aggressive treatment. The typical fine needle aspiration cytology (FNAC) findings in SDC include cellular smears showing tumor cells with eccentric pleomorphic nuclei and a granular cytoplasm arranged in flat sheets or cribriform patterns against a necrotic background. However, the presence of mucin-containing cells in SDC has been rarely described. We report the FNAC findings in a patient with histologically confirmed SDC that demonstrated numerous mucin-containing cells and was subsequently misdiagnosed as a high-grade mucoepidermoid carcinoma. Here we discuss the problems involved in distinguishing SDC from high-grade mucoepidermoid carcinoma on the basis of cytologic findings alone.

Mucoceles of the minor salivary glands are the most common cystic lesions affected the oral mucosa. They are believed to be the result of trauma to the salivary duct caused, for example, by biting the lip, cheek, or tongue. Surgical excision has been the most common treatment for these lesions, but occasional recurrences develop after excision because surgical trauma may damage the surrounding minor salivary glands Although various alternative nonsurgical approaches, such as steroid infection, application of gamma-linolenic acid, have also been reported, they are not used routinely, Lasers, particularly the carbon dioxide laser, have been used in the management of mucoceles. Although this treatment requires specialized equipment. Cryotherapy is another effective nonsurgical method for treating mucoceles. Clinically, cryotherapy has primarily been applied to the treatment of leukoplakia and hyperplastic, granulomatous, vascular, and pigmented lesions. Limited information, however, is available on the application of cryotherapy in salivary gland lesions, including mucoceles. A simple and easy cryotherapy to treat a mucocele on the lower lip is described. A 25 years old female patient with a mucocele on the lower lip was treated by direct application of liquid nitrogen with a cotton swab. The lesion was exposed to 4 or 5 cycles composed of freezings of 10-30 s and thawings of double the freezing times. No anesthesia was required. The lesion nearly disappeared without scar 10 days after the cryotherapy. Cryotherapy has become an established nonsurgical method, characterized by its simple application, therapeutic effectiveness, painless during the procedure and low incidence of secondary infection and hemorrhage.

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.

Mammary analogue secretory carcinoma (MASC) is a rare malignant tumor of the salivary gland, which was first described in 2010. In this case report, we describe a 62-year-old woman with a MASC of the parotid gland, who initially presented with an asymptomatic preauricular mass. At first, computed tomography (CT) and fine needle aspiration cytology were performed; these suggested a possible Warthin's tumor but also some suspicious malignant findings. For the main treatment, adequate parotidectomy was conducted via modified Blair incision to remove the tumor. Postoperative pathology report revealed a MASC of the parotid gland. Specific MASC findings were observed upon immunohistochemical examination.

Parotid gland plays the most critical role in saliva secretion in the oral cavity. Parotid gland injuries due to facial trauma can cause various complications such as formation of a fistula or sialocele. Thus, such saliva-related complications can interfere with wound healing and increase the risk of infection. Several previous studies have discussed the treatment of fistula or sialocele. Nonetheless, prevention of such complications is of utmost importance. We present a case of parotid gland injury due to trauma to the cheeks that was surgically treated, with early postoperative management involving oral administration of nortriptyline and closed drainage, without complications.

Basal cell adenocarcinoma is a rare, recently described neoplasm of the salivary gland. We have experienced three cases of basal cell adenocarcinoma of the parotid gland. The tumors from patient 1 and patient 2 showed intraparotid growth in superficial lobe without cervical lymphnode metastasis. So, patient 1 and patient 2 underwent only a superficial parotidectomy and subdigastric lymphnode dissection without any adjuvant therapy. They are alive without recurrence or distant metastasis. But that of patient 3 showed widely invasive growth with multiple cervical lymph node metastases. The CT scan showed a $8{\times}7cm$ sized huge mass replacing the parotid gland with irregular margin and multiple lymphnode enlargements along the internal jugular vein. Total parotidectomy with sacrifying the facial nerve and standard radical neck dissection were caried out. Microscopically, the tumor consisted of solid nest and sheet of uniform basaloid cells separated by a fibrous connective tissue stroma with the evidence of lymphovascular invasion. As a result of the lymphnode metastasis and invasiveness of the tumor, radiation therapy was given postoperatively. We thought that close follow-up would be mandatory in this patient because of high risk of possible local recurrence and distant metastasis.

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.

Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.
