Schwannomas are benign tumors arising from the nerve sheaths of peripheral, autonomic and cranial nerves. Between 25% and 45% of all schwannomas occur in the head and neck region but only 4% involve the nasal cavity and paranasal sinus. Moreover, schwannoma of the pterygopalatine fossa is extremely rare. We present a case of schwannoma of the pterygopalatine fossa in a 43-year-old woman. The patient was surgically managed with endoscopic transnasal approach combined with transantral approach. After 16 months, the patient shows no evidence of recurrence.

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.

Warthin's tumor (WT) is second most common neoplasm in the parotid gland and it can be accompanied by inflammation and necrosis. The chest wall inflammation may present a rapid and fatal clinical course and secondary to parotid abscess is extremely rare. An 81-year-old man came to emergency room complained of rapidly enlarged left parotid mass and inflammatory symptoms and signs around the upper lateral neck. We performed incision and drainage with adequate infection control. He was pathologically diagnosed as abscess. We report the unique and instructive clinical case with a literature review.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening one syndrome of excessive immune activation. This immune dysregulation disorder is prominently associated with cytopenias and combinations of clinical signs and extreme inflammation symptoms. For survival, it is important to diagnose early and treat appropriately. We report a case of 10 years old boy who was admitted to the hospital with a month history of fever and cervical lymph node enlargement. There were signs of hemophagocytic histiocytosis in the lymph node and bone marrow. The etiology, diagnosis, and treatment of hemophagocytic lymphohistiocytosis are reviewed.

Liposarcoma is a malignant tumor that occurs in adipocytes, accounting for 5% of all sarcomas. Generally, it has no symptoms and it occurs in any parts of the body. There are various types of liposarcoma. Of these, 40-45% are known as highly differentiated liposarcoma, and highly differentiated liposarcoma is also referred to as atypical lipomatous tumor. We report a case of an atypical lipomatous tumor on the left neck.

Myoepithelioma is a rare benign neoplasm that mostly arises in the major salivary glands and sometimes in the minor salivary glands, which account only for less than 1% of all salivary glands neoplasms. However, its extra-salivary involvement is even rarer and only a few cases of nasal cavity myoepithelioma were reported in the English-language literature so far. In this case report, we present a 40-year-old female with unilateral nasal obstruction diagnosed as myoepithelioma of the nasal septum and treated with endoscopic sinus surgery.

Lymphadenoma is a rare benign neoplasm of the salivary gland. Herein, we present a 67-year old woman with lymphadenoma in the parotid gland. Physical and radiologic examinations of parotid lymphadenoma are not specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that lymphadenoma may occur in the parotid gland mimicking the other more frequently observed lesions.

Mucinous adenocarcinoma (MAC) is a rare malignant neoplasm that occasionally occurs in the large intestine (colon), followed by the pancreas, ovary, lung, prostate, and breast. It is characterized by large amounts of extracellular epithelial mucin that contains tumor cell nests. We herein present a unique case of MAC originating from minor salivary gland, the second to be reported in literature in South Korea. We report a case of MAC in the tongue considered to be developed from minor salivary gland with a review of literature.

Papillary thyroid carcinoma frequently invades the lymph node, trachea, esophagus and perithyroid tissue. However, direct extension to posterior pharyngeal area is known to be rare. A 64-year-old male was referred to our clinic presenting as posterior pharyngeal mass during gastrofiberscopy. The neck CT scan showed soft tissue mass in retropharynx and lymph node in right level III with calcifications. We performed the total thyroidectomy with selective(level II, III, IV) and anterior compartment neck dissection. In operative findings, the right thyroid mass were connected to the retropharynx through the posterior portion of inferior constrictor muscle. Histopathologic findings revealed the papillary thyroid carcinoma extended to retropharynx. We report a unique case with a literature review.

The salivary gland consists of major and minor glands. The major glands are parotid, submandibular and sublingual glands. The numerous minor salivary glands are located in the mucosa of the upper aerodigestive tracts. Tumors of the salivary gland are relatively uncommon, and the incidence of the salivary gland tumor among the head and neck neoplasm is approximately 3%. Surgery is the primary treatment of choice for the most tumors of the salivary glands. Author reviewed the recent reports of salivary gland neoplasms of Korea and foreign institutes and suggest the guideline of managemnt of salivary gland tumors.
