  • The tumor in accessory parotid gland (APG) is rarely occurred and its incidence is about 7.7% of all parotid gland neoplasms, but has a higher frequency of malignancy than major salivary glands. The mucoepidermoid carcinoma is the most common malignancy in APG, while B-cell lymphoma is less than 2%. It is often appeared as superficial mass in mid-cheek area. This lesion requires differential diagnosis with epidermoid cyst, lipoma, neurogenic tumors, Stensen's duct stone, lymphadenopathy and hemangioma etc. The mucosa associated lymphoid tissue (MALT) lymphoma, which is also termed extra-nodal marginal zone B-cell lymphoma tends to be localized disease for long time and has a relatively indolent course. We recently encountered a 69-year-old man with superficial solitary mass on the right cheek area that finally diagnosed as MALT lymphoma in APG. We report the rare and unique case with brief literature review.

  • Adenoid cystic carcinoma(ACC) is a rare malignant tumor that occurs in exocrine glands such as major and minor salivary glands, lacrimal glands, ceruminal glands. It has a tendency for delayed distant metastasis and long clinical course. ACC of the lacrimal gland is generally found in adults and is usually managed by radical orbitectomy and supplemental external beam irradiation. The authors present two cases of recurrent lacrimal gland ACC with review of the literature.

  • Carcinoma ex pleomorphic adenoma is rare, aggressive, poorly understood malignancy that occurs in the salivary glands. The patient was 70-year-old male presenting ovoid elevated submandibular mass that has been present for 30 years and rapid growing for 6 months. The initial cytologic finding by fine needle aspiration biopsy showed highly malignant cells and the radiologic finding revealed a $3.6{\times}3.7{\times}4.8cm$ sized mass with cervical lymphadenopathy. After wide excision of submandibular gland and modified radical neck dissection, the histologic examination revealed that tumor was composed partly of a benign pleomorphic adenoma and partly of an adenocarcinoma component with areas of calcification and frequent angiolymphatic invasion. We present a rare case of adenocarcinoma ex pleomorphic adenoma with tumor thrombus in the submandibular gland.

  • Malignant oncocytoma(oxyphil cell adenoma) is a extremely rare malignant tumor of the salivary glands and almost occurs in the parotid gland. A case of malignant oncocytoma of the parotid gland occurring in a 63 year old man is reported. Establishing a diagnosis of malignant oncocytoma essentially requires the application of two sets of criteria to the tumor under examination. First, the tumor cells must be identified as oncocyte and second, malignancy must be determined. Histochemical stains are not as useful as generally believed. Electron microscopy confirms the diagnosis by demonstrating an abundance of mitochondria. The diagnosis of malignant oncocytoma depends on several additional criteria in addition to cellular and nuclear pleomorphism, including lack of encapsulation, local infiltration, perineural and intravascular growth, and regional and/or distant metastasis. Satisfactory results from surgical resection and postoperative radiotherapy in our patient serve as additional experience in the treatment of this rare malignancy.

  • Venous malformation with phleboliths is uncommon cause of unilateral parotid swelling. The clinical and radiographic appearance of venous malformation with phleboliths may masquerade as sialolithiasis. A 49-year-old female complained about unilateral parotid swelling for 6 years. Preoperative evaluation including computed tomography and sonography showed the suspicion of venous malformation with phleboliths. Superficial parotidectomy was performed. Pathological examination confirmed that the mass was venous malformation with phleboliths combined with sialolith in the parotid gland. We present the case of unilateral parotid swelling caused by a venous malformation combined with sialolithiasis.

  • Basal cell adenocarcinoma is 1 ~ 2 % of salivary gland carcinoma. It was recently classified as low grade malignancy. It is low grade malignant counterpart of basal cell adenoma. It has similar morphologic attributes with basal cell adenoma, but it has distinctive malignant potential including infiltrative growth into surrounding tissues and distant metastasis. Recently, we have experienced a case of basal cell adenocarcinoma arising from the bilateral parotid gland in a 38-year old woman who was previously operated on superficial parotidectomy due to pleomorphic adenoma. We report this rare case with a review of literature.

  • Mantle cell lymphoma (MCL) is a rare subtype of B-cell neoplasm and it accounts for about 3~6% of all non-Hodgkin's lymphomas. It occurs mainly in middle-aged or elderly man, involving the extra-nodal sites such as gastrointestinal tract, bone marrow and Waldeyer's ring. The incidence of the MCL in salivary gland is about 3%. The blastoid MCL is a rare variant and it has a very aggressive clinical course. It is extremely rare to be arising from the parotid gland. To our knowledge, similar case has not been reported in domestic literature, one case has been described in English literature. We experienced a rare and unique disease entity and report it with brief literature review.

  • Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a rare immunological small vessel disease which usually affects respiratory tract and kidneys. However, salivary gland involvement in GPA is rare as a primary manifestation. We report a case of GPA with the primary presentation of submandibular gland involvement. A 48-year-old female patient presented submandibular swelling with a skin defect that lasted for 1 month. Although the biopsy result was chronic inflammation, the skin defect did not heal for a month. Further imaging study revealed multiple lung and renal masses. More clinical manifestations such as gingivitis, ischemic change of finger joint and nasal tip skin, and positive c-ANCA test was presented. Additional biopsy was made at the submandibular gland, lung, and finger skin. The patient was finally diagnosed with GPA and treated with steroid pulse therapy and cyclophosphamide. The patient showed improvement of prior clinical symptoms.

  • Follicular dendritic cell sarcoma (FDCS) is rare lymphoid sarcoma occurs anywhere in body, mostly in lymph nodes. Sixty-two-year-old man presented left submandibular gland region mass for 5 months. Mass excision with submandibular gland resection was performed. Histopathology showed proliferation of spindle and ovoid cells with storiform arrangement which were positive for CD21, CD23, Vimentin, Ki-67, suggested FDCS in submandibular gland region lymph node. Tumor size was 3cm with no involvement of resection margin, nor cellular atypia and necrosis, so regular follow up was performed. After 4 years, new enhancing mass in left submandibular area was found. Wide excision of mass with neck dissection on left level I-III was performed. Histopathology confirmed recurrence of FDCS. The patient underwent radiation therapy from left mandible to hyoid area. After 2 years, new nodule was found in left lung upper lobe, and wedge resection confirmed metastasis of FDCS. The patient is on adjuvant chemotherapy.

  • Advances in medical procedures and utilization of medication have resulted in expanding aged population, which leads to increased aged patients with salivary hypofunction and its associated symptoms in dental clinic. The purpose of this study was to investigate clinical characteristics of patients with dry mouth and its correlation with their salivary flow rate. Forty dry mouth patients (7 males, 33 females, mean age 42.0 years) whose flow rate of unstimulated whole saliva was less than 0.15 ml/min were included and their gender- and age-matched controls (7 males, 33 females, mean age 42.9 years) who did not report any complaints, suggestive of salivary gland dysfunction and had the flow rate of greater than 0.20 ml/min were included for comparison. The salivary flow rate was measured in both unstimulated and stimulated conditions. Dry mouth-related clinical information including history, dry mouth associated symptoms, exacerbating and relieving factors, drugs, systemic diseases, and family history was investigated using questionnaires. The differences in distribution of patients and control subjects to each question and their relation to the salivary flow rate were analyzed and we came to following conclusions. 1. There were statistically significant differences in the distribution of patients and controls to the following questions: the period and frequency of suffering from dry mouth; severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods, severity of discomfort in usual life due to dry feeling; self-assessment of residual salivary volume; taking medications. 2. The patients had more stress-related medical histories including indigestion, insomnia, and gastritis compared with controls. The patients took many kinds of medications to control their systemic diseases. 3. There were statistically significant differences in the salivary flow rate between different groups of patients to following questions: severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one. 4. The salivary flow rate of patients taking medications was significantly less than that of patients who did not take medications. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one.
