The Mantle cell lymphoma(MCL) is a relatively rare subtype of malignant lymphoma characterized by chromosomal translocation t(11 ; 14)(q13 ; q32), positive response for CD5, and nuclear cyclin D1. It is account for an estimated 3-6% of all non-Hodgkin's lymphoma. The involvement of extra-nodal site is not uncommon, whereas salivary glands are rarely affected. It is more commonly occurred in men and old age and approximately 75% of cases are diagnosed with advanced stage. It is usually characterized by an aggressive clinical course, and the prognosis is poorer than other type of head and neck lymphoma. We recently encountered a 69-year-old female with mass in parotid tail and upper neck, and it was diagnosed as mantle cell lymphoma. We report the unique case with a review of literature.

The extranodal non-Hodgkin lymphoma is uncommonly occurred in larynx, accounting for less than 1% of all laryngeal neoplasm. In general, the laryngeal lymphoma is appeared as submucosal mass without mucosal ulceration and is most commonly found in supraglottis. The primary laryngeal lymphoma constitute a diagnostic challenge because they are characterized by absence of clinical and gross differential criteria, compared with squamous cell carcinoma (SCC). We encountered a 74-year-old man with hoarseness and lump sensation in the throat. On direct laryngoscope, multiple ulcerative and exudative mass in glottis and supraglottic areas were observed. The patient was finally diagnosed as large B-cell lymphoma through the laryngeal microsurgery. He received radiation therapy and there is no evidence of recurrence. Although the laryngeal mass has superficial mucosal change, primary laryngeal lymphoma must be included in the differential diagnosis.

The lobular capillary hemangioma (LCH) was previously known to pyogenic granuloma and is benign vascular lesion which grows rapidly on skin and mucosa. It arises from whole body, but oral and nasal cavities are most predilection sites in the head and neck area. The laryngeal LCH looks like a granulomatous lesion of posterior glottis and its common etiology are tracheal intubation and laryngopharyngeal reflux disease etc. The LCH in larynx can cause blood tinged sputum and lump sense. The lesions refractory to medical therapy or causing dyspnea may require surgical excision. A 74-year-old man who presented gradually aggravated dyspnea, lump sensation and hoarseness of one month came to our hospital. The stroboscopic examination revealed large well-margined glottic mass. It was excised with $CO_2$ laser and finally diagnosed as LCH. We present a rare unique case of glottic LCH with a review of literatures.

The pilomatricoma is a benign skin neoplasm arising from hair follicle matrix cells, and it comprises approximately 0.12% of all benign skin tumors. It occurs most commonly in head and neck. It usually tends to occur in childhood or school-age. Mainly, it exists in single subcutaneous or intradermal nodule and grows very slowly. The diagnosis is confirmed by histopathologic examination. Histopathologically, it is characterized by basaloid cells, enucleated shadow cells and calcifications in the shadow cell. However, it is rare to present extensive ossification in pilomatricoma. The treatment of choice is wide local excision. A 66-year-old man came to our clinic and he complained of two masses on right parotid tail and posterior neck. We performed excisional biopsy on posterior neck and partial parotidectomy. The pathology of former was pilomatricoma with extensive ossification. We report a rare unique case of pilomatricoma with brief review of literature.

The anterior mediastinal tracheotomy(AMT) facilitates resection of stomal recurrence after total laryngectomy and tumors involving the cervicothoracic trachea and esophagus. An 81-year-old-man came to our clinic due to the progressive dyspnea during three months. He received the total laryngectomy five years ago. We diagnosed as Sisson type I stomal recurrence and then performed the wide excision, both selective neck dissection, sternal manubrium resection and AMT. Before surgery, we planned the pectoralis major myocutaneous flap. Unluckily we could not fulfill this procedure because of patient's medical status during anesthesia. The tracheocutaneous fistula was observed in the second postoperative day. He expired due to the huge bleeding from the wound. When AMT is performed, exact manipulation of major vessels and adequate flap are mandatory these elevate the feasibility of AMT.

Salivary gland tumors comprise almost 5% of head and neck malignancies, and minor salivary gland tumor which account for 10-15% of all salivary gland neoplasm are infrequently malignant. The mucoepidermoid carcinoma (MEC) is second most common tumor in minor salivary gland. It usually presents as a painless, rubbery-hard or soft mass, which may be fixed or mobile into the underlying structure. The predilection sites of intraoral MEC are palate, cheek, mandible, lip, and tongue, etc. There are very few published reports of MEC occurred in retromolar trigone. Only one case has been reported so far. Recently, we experienced a-70-year old man with a mass in retromolar trigone, which was finally diagnosed as MEC. We report the unique case with literature review.

The extranodal nasal NK/T-cell lymphoma was formerly known as lethal midline granuloma due to its most common clinical pattern like a destructive midline facial tumor. It often spread to other extranodal sites, such as skin, soft tissue, testis, upper respiratory tract, and gastrointestinal tract etc. For this reason, the term of extranodal NK/T-cell lymphoma, nasal type is preferred. Its disease entity may have a prominent admixture of inflammatory cells and necrotic tissues, further causing difficulty in diagnosis. A 44-year-old man was visited to our clinic with complaints of dysphagia and odynophagia during six months. He underwent three times punch biopsies and then, two times incisional biopsies. Finally, He was diagnosed as extranodal NK/T-cell lymphoma, nasal type involving oropharynx and supraglottis. We report an extremely rare case of extranodal NK/T-cell lymphoma, nasal type occurred in oropharynx and supraglottis with a brief review of literature.

The most common cause of treatment failure in oral cavity cancer is when it is found to have local recurrence, usually occurring in the ipsilateral cervical lymph node. On the contrary, it is extremely rare to find local recurrence in soft tissue metastasis (STM) in the contralateral neck. Furthermore, lung cancer and malignant lymphoma are most commonly confined to their primary sites. The poor general condition increases the likelihood of STM, which indicates bad prognosis. A 72-year-old man with a hard and fixed mass on the right submandibular space visited our clinic. He had received a wide excision with local flapreconstruction for squamous cell carcinoma in the left corner of lower lip 18 months ago. We performed the wide excision with bilateral selective neck dissection (I-III), and he was finally diagnosed as STM from contralateral lip cancer. We report this unique and rare disease entity with a literature review.

Epidermal cysts are generally benign tumors that usually originate from the skin caused by inflammation of hair cortex and proliferation of epidermal cells within the dermis; however, for these cysts to occur in the bony external auditory canal (EAC) is rare. They are often present as a solitary, painless lesion and usually asymptomatic and the diagnosis depends on the results of the histological examination. In treatment, the cyst wall must be completely removed surgically. We recently encountered a 82-year-old male with a mass in the right EAC. An otoscopic examination showed a polypoid mass on the bony EAC, which was finally diagnosed as epidermal cyst after an initial misdiagnosis as EAC carcinoma. We report the rare, unique case with literature review.

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.
