The most widely accepted hypothesis about the origin of branchial cleft cysts (BCC) is developmental theory. The second most accepted is acquired inflammatory theory. A 57-year-old woman visited our department, presenting with a soft and well-margined round superficial mass in the lower midline neck. We performed an excisional biopsy to confirm the disease. The mass was located superficial to the sternohyoid without severe adhesion and abnormal communication. The pathology was proven to be BCC. We presumed that this is irrelevant to the established developmental theory, and a recurrent pharyngeal inflammation might lead to the transformation of aberrant epithelium into a cervical lymph node. We report rare and unusual type of BCC with a literature review. To the best of our knowledge, there have been two similar clinical cases that have been reported earlier.

The pilomatricoma is a benign skin neoplasm arising from hair follicle matrix cells, and it comprises approx-imately 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 ossifica-tion 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 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.

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.

Background and Objectives:Performing cochlear implantation is a difficult process for those patients who have received radical mastoidectomy due to chronic otitis media. However, we could perform a single stage operation successfully without external auditory meatus and mastoid complete obliteration. Materials and Methods:The authors performed 13 cases of cochlear implantation in open cavity mastoidectomy state patients without obliteration of mastoid or with the partial obliteration of mastoid from July 2011 to July 2015. Of these thirteen patients, eight patients received cochlear implantation in the site of open mastoid cavity and others in opposite site. The medical records and radiological findings were reviewed retrospectively. Results:Three of eight patients who had undergone open cavity mastoidectomy did not perform mastoid cavity obliteration during cochlear implantation. Another five patients with an open cavity mastoid had undergone the partial obliteration of mastoid during cochlear implantation. There were no postoperative medical complications such as infections of mastoid cavity, recurrence of cholesteatoma and necrosis of skin flap during following up periods except for 1 case of delayed electrode extrusion. Conclusions:The advantages for this procedure as the following. First, we could overcome the difficulty of radiological diagnosis for primary or recurrent cholesteatoma due to mastoid obliteration. Second, a single-stage procedure allowed the implantation as safe as two-stage procedures. At last, non-obliterative or partial obliterative procedures may replace the typical mastoid obliteration process during cochlear implantation for it allows a safe procedure for open cavity patients reducing complications such as electrode extrusion or infection.

Mucosa-associated lymphoid tissue (MALT) lymphoma, known as a distinctive type of non-Hodgkin’s lymphoma, is an extranodal marginal zone B-cell lymphoma. It most frequently occurs in the stomach but has also been described in various non-gastrointestinal lesions, such as the salivary glands, conjunctiva, thyroid, orbit, lung, breast, kidney, liver, and prostate etc. It occurs very rarely in buccal mucosa. The MALT lymphoma tends to remain localized for long periods and respond to locally direct therapy. We recently encountered an 80-year-old male presenting with a foreign body sensation in the oral cavity; he was finally diagnosed as MALT lymphoma. We report this rare and unique case with a review of literature.

Renal cell carcinoma (RCC) is known for its high propensity for early metastasis and one third of patients diagnosed with RCC present with metastatic disease at the time of diagnosis. RCC commonly metastasizes to the lung, bone, liver, brain, and skin by hematogenous spread, whereas metastasis to the head and neck region is rarer. In cases of head and neck metastasis, the thyroid accounts for a large percent. Parotid metastasis from renal cell carcinoma is an extremely rare finding. We recently encountered a 67-year-old man with left parotid mass and finally diagnosed as metastatic renal cell carcinoma. We report the rare case with a review of literature.

Background and Objectives The association between hearing impairment and cognitive function has been established in previous studies. The aim of this study was to compare the effects of conventional hearing aids and middle ear implants on cognitive function. Subjects and Method This study included 22 participants who underwent middle ear implantation between October 2013 and September 2016. Their mean age at surgery was 70 years. Using Pure tone audiometry (PTA), the Speech discrimination test (SDT), and the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, we compared audiologic benefits of three conditions [without hearing aids, with conventional hearing aids, or with Vibrant Sound bridge (VSB)]. Cognitive ability was evaluated using neuropsychological testings (Seoul Neuropsychological Screening Battery) at intervals of approximately eight weeks. Results The results of PTA showed a 7.96 dB HL gain with conventional hearing aids and a 10.00 dB HL gain with the use of VSB. SDT results showed a 4.10% gain with conventional hearing aids and a 10% gain with the use of VSB. Results of the APHAB questionnaire showed a significant increase with the use of VSB compared to conventional hearing aids. In the Korean Mini-Mental State Examination, a slight improvement was observed after middle ear implantation. In the Digit Span Test and Korean-Boston Naming Test, a significant improvement was seen with the use of VSB compared to conventional hearing aids. Conclusion The use of middle ear implants in rehabilitation of hearing communication in patients showed improvements in cognitive abilities, compared to the use of conventional hearing aids.

Liposarcoma is a malignant tumor originated from adipose tissue, accounting for 20% of all soft tissue sarco-mas. A 69-year-old man with anterior and posterior neck mass visited to our department and we performed an excisional biopsy in level Ι. Histopathological examination revealed liposarcoma, so we performed wide exci-sion in anterior and posterior neck, and adjuvant radiotherapy. We report a unique case of well-differentiated li-posarcoma on anterior and posterior neck with literature review. To our best knowledge, such case has not been reported earlier in Korea previously.
