Epithelial-myoepithelial carcinoma is a rate low-grade malignant salivary neoplasm that usually occurs in the parotid gland but can also arise in minor salivary glands. We report a case of a primary epithelial-myoepithelial carcinoma of the lung neoplasm. The patient was 48-year-old women who presented with dry cough of 1 month duration. A right middle lobe endobronchial lesion was identified bronchoscopically. The bilobectomy of RML & RLL was performed, the pathologic result was epithelial-myoepithelial carcinoma.

Purpose: Parotid neoplasia are relatively frequent, representing approximately 3% of all tumors in the head and neck regions. But incomplete resection and misdiagnosis of parotid gland is followed by multiple tumor invasion, tumor recurrence, and other iatrogenic tumor formation. In patients undergoing parotidectomy for confirmed or suspected malignancy, the traditional or modified rhytidectomy incision may prove suboptimal because it does not easily lend itself to a continuous neck dissection. Similarly, patients with tumors of the anterior accessory lobe or patients with large anterior tumors may also require the modified Blair incision for adequate surgical exposure. This report serves to revisit the topic of accessory and parotid gland neoplasms to emphasize proper management, particularly the surgical aspects, so that consequences of recurrence are avoided. Methods: This is a retrospective review of our experience with two cases of parotid tumors; one accessory parotid gland neoplasm and one parotid gland neoplasm. We report the case of parotid tumor and epidermal cyst in a 54-year old male patient and the case of case of recurrent parotid tumor with local invasion in 30-year old male patient. Results: All were removed through a modified Blair incision. Pathologic report notified that One was found pleomorphic adenoma and epidermal cyst, and the other one pleomorphic adenoma with subcutenous invasion. The patients recovered well without any complication such as infection, hematoma, facial nerve palsy, and necrosis of skin flap. Patients were discharge POD#7. Patients were followed up to for 1 year and they have no sign of recurrence. Conclusions: A high index of suspicion, prudent diagnostic skills(including fine-needle aspiration biopsy, CT, US), and meticulous surgical approach are the keys to a successful management of these lesions. We experienced two cases of parotid neoplasia, in the treatment of tumor reccurence & iatrogenic tumor arising from the parotid gland and are presented with the review of literatures.

The differential diagnosis of lesions in buccal area include lipoma, neurofibromas, epidermoid cyst, salivary ducts calculus, hemangioma, lymphadenopathy. Accessory parotid glands is defined as salivary gland tissue adjacent to the parotid duct, but separated from the body of parotid and it may be found in approximately 20% of human parotid glands. The appearance of an accessory parotid tumor is rare, with a reported frequency of 7.7% of all parotid neoplasm. Angiomyoma, which is also termed angioleiomyoma, is a rare solitary subcutaneous tumors arising from the vascular smooth muscle. It often occur in the extremities and is rarely found in buccal area. We present 2 cases of rare tumor in buccal mass and resected surgically without facial nerve palsy.

Initially described in 1929, Warthin's tumor is a benign neoplasm predominantly found in the parotid gland of the salivary glands. Warthin's tumor is synonymous for cystadenoma lymphomatosum, adenolymphoma, and cystadenolymphoma. This tumor usually causes minimal pain, but the patient may complain of tinnitus, pain in the ear, or deafness. The tumor is treated with surgical excision, which is easily performed due to the superficial location of the tumor. In our case, a 69-year-old man visited our clinic primarily complaining of swelling in the left parotid gland area. Computed tomography revealed well-defined margins of the tumor in the superficial lobe of the left parotid gland and heterogeneous contrast enhancement. We performed superficial parotidectomy, with the pathological examination confirming Warthin's tumor. We report a typical case of Warthin's tumor and a literature review.

Basal cell adenoma (BCA) is a rare, benign neoplasm that most frequently arises in the parotid gland. We treated a 54-year-old female patient with BCA that had developed in the deep portion of the left parotid gland. The patient presented with gradual facial swelling with no other symptoms. We performed a total parotidectomy to excise the mass, but we preserved the facial nerve. Histopathology revealed a well-encapsulated mass. The tumor was composed of islands of comparatively uniform, small, dark, basaloid epithelial cells in the stroma. Histologic and immunohistochemical studies concluded that the BCA tumors were mostly trabecular. Postoperatively, there was no facial nerve weakness, and the tumor did not recur during the 24-month follow-up period.

이하선에 생기는 전이성 다형태 선종은 매우 드문 질환으로서 조직학적으로는 양성이나 임상적으로는 전이를 일으키는 논쟁의 여지가 많은 병변이다. 저자들은 이하선의 다형성 선종으로 절제술을 경험한 57세 남자에게서, 4년 후에 흉막과 우측 폐, 종격동, 심낭, 늑간근의 다발성 전이를 진단하여 전이암 절제술을 경험하였기에 보고하고자 한다.

Parotid canalicular adenoma is a benign neoplasm that is predominantly composed of branching and interconnecting cords of single or double rows of columnar epithelium in a very loose stroma. There has been considerable confusion in the literature concerning the terminology of canalicular adenoma. However, thesedays it has been newly-recognized as a discrete entity of the monomorphic adenoma group. Canalicular adenoma has a remarkable predilection for occurrence in the minor salivary glands such as the upper lip, in contrast with basal cell adenoma that occurs predominantly in major salivary glands such as the parotid gland. We have experienced a case of canalicular adenoma of the parotid gland in a 65-year-old woman. The patient had a palpable mass on the preauricular area for the last 15 years and recently noticed a mild pain and discomfort on the mass. Neck ultrasonography showed a low echogenic mass of 1.0cm in diameter in the right parotid gland and a neck CT scan showed a well-enhanced rectangular-shaped mass. A superficial parotidectomy was performed for the lesion and the final pathologic diagnosis turned out to be 'multifocal canalicular adenoma'.

A lipoma is a benign tumor of matured adipose tissue that usually occurs at the shoulder, back, and abdomen. 13% of lipomas occur in the head and neck area. However, the incidence of lipoma in the parotid gland is very low, approximately 2.5%. A conservational surgical excision is recommended in cases of lipoma of the parotid gland, with only 1-2% of lipomas recurring. We report a case of a lipoma in the parotid gland that was removed by conservational surgical excision. The lesion was exposed by the pre-auricular approach and the tissue was detached. After the parotid gland envelop was exposed, a yellowish mass is observed that was easy to remove due to capsulation. Most authors recommend a surgical excision of the superficial lobe of the parotid gland as the treatment for a lipoma in the parotid gland. However, enucleation only may be a sufficient treatment when a lipoma occurs in the superficial lobe or around the parotid gland. A patidectomy is not needed when a lipoma is located at the superficial lobe of the parotid gland, and a conservational surgical excision is suitable. Therefore, a clinical diagnosis is important for reducing the damage to the facial nerve.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

Squamous cell carcinoma, which is a common primary head and neck malignant neoplasm that is usually restricted to the mucosal surfaces of the upper aerodigestive tract and skin, is very unusual in the major salivary gland. Among them, few cases are regarded as primary carcinomas. In this article, we present two cases of squamous cell carcinoma in the parotid gland, who first presented with painful mass on infraauricular area.
