This article discusses the diagnosis, anatomic consideration, and surgical management of masseter muscle hypertrophy. Surgical correction is advised for patients who have esthetic complaints. Esthetic improvement can be achieved by surgery and not by conservative treatment. Recently, the intraoral method, which leaves no scar on the face and minimizes the possibility of injury to the marginal branch of the facial nerve, has been supported by many surgeons. Patients who complained of marked swelling of unilateral or bilateral mandibular angle area and showed abnormal bony growth at the mandibular angle area and enlarged masseter muscle received mandibular angle shaving and excision of the inner layer of masseter muscle with intraoral approach. After operation, physiotherapy was done with EAST(eletrical acupuncture stimulation therapy) for encouraging the mouth opening and reducing the swelling. They showed early maximum mouth opening and reduction of swelling.

Glandular odontogenic cyst (GOC) is an intraoral cyst originated from serre remnants which has incidence of rare frequency. Only 111 cases have been reported since Gardener first introduced it in 1987. The clinical features are the following components: cortical bone thinning, locally aggressive root resorption, non-painful swelling. The following recurrences rate are 64.3% in conservative treatment, and 0% in wide excision for instance, segmental or marginal mandibulectomy. So, its prognosis is similar to that of odontogenic keratocyst and ameloblastoma. Therefore, periodic recall follow ups are essential to detect disease recurrence. Here, we will report the first case of GOC diagnosed in our department considering with references. And we share this treatment experience because these aggessive lesions may be misjudged for simple dental cyst.

Malignant lymphoma rarely occurs in the larynx and hypopharynx. Few cases of malignant lymphoma in the larynx were reported in Korea. However, malignant lymphoma in the hypopharynx had been not reported in Korea. A 68-year-old woman came to the outpatient clinic with a foreign body sensation in her throat. A round, smooth margin, bright pink-colored mass was confirmed by the laryngoscopy. The patient took neck computer tomography. A small bulging of mucosa was observed, but there was no peripheral infiltration or abnormally enlarged lymph nodes. We did excision using CO2 LASER. She was finally diagnosed with mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). After diagnosis, several image studies confirmed that there was no metastatic lesion. She got only radiotherapy after that and kept a complete response state for over 2 years.

A 74-year-old female presented with a complaint of dry mouth, continuous spontaneous burning sensation in the tongue, and asymptomatic submucosal soft tissue mass on both sides of the lower labial mucosa. She refused to undergo total excision of the mass due to concern about the possibility of complications such as nerve damage because of the large size of the mass. As her clinical features and magnetic resonance imaging indicated the possibility of Sjögren's syndrome, a biopsy of the minor salivary gland of the right lower lip was performed. Consequently, she was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma. Although the patient had typical signs and symptoms of Sjögren's syndrome, the histopathological result of MALT lymphoma made it impossible to determine whether the patient had a history of Sjögren's syndrome. For patients with risk factors for MALT lymphoma, such as Sjögren's syndrome, a biopsy of the labial minor salivary gland with immunohistochemical staining can be helpful in the diagnosis of not only Sjögren's syndrome but also MALT lymphoma.

To evaluate the role of radiation and chemotherapy after limb-saving operation in the management of soft tissue sarcoma, the authors analysed retrospectively 33 patients treated in department of Orthoaepdic Surgery and Radiation Therapy, Catholic University Medical College, in terms of survival rate, local recurrence rate and prognostic factors. There were 16 males and 17 females. The age distribution ranged from 16 to 81 years with mean age of 48. The follow-up period ranged from 2 to 10 years with average of 5.5 years. The histologic diagnoses were 9 liposarcoma(27.2%), 8 malignant fibrohistiocytoma(24.2%), 7 unclassifiable(21.2%), 3 rhabdomyosarcoma(9.1%), 2 malignant schwannoma, 2 synovral sarcoma, and 2 fibrosarcoma(6.1%) in orders. While marginal and intralesional margins were gained in 24 patients(72.7%), wide and radical margins were obtained only in 9 patients(27.3%). On postoperative 3 weeks, local irradiation of 5000-7000 cGy was delivered to all patients by shrinking field technique for 5-8 weeks. Of 33 patients, 16(45.5%) patients were received adjuvant chemotherapy in combination of adriamycin, cyclophosphamide & vicristine, or VP16 & ifosfamide based on histologic type and obtained surgical margin. The survival rates by direct method at 2 years and 5 years were 58% and 37% respectively. Local recurrences occured in 15 patients(45.5%) at average 16 months after operation. Survival rates at 2 years and 5 years were 37% and 22% in case of intralesional and manginal excision, 75% and 47% in case of wide and radical excision respectively with statistical significance(p<0.05). They were 25% and 17% in the presence of local recurrence, 67% and 42% in the absence of local recurrence respectively with statistical significance(p<0.05). Even though there was no statistical correlation between survival rate and tumor size(p>0.05), the authors considered tumor size as a significant prognostic factors as well as surgical margin and the presence of local recurrence.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.

Purpose: Contralateral reduction mammaplasty at the time of breast reconstruction using autogenous tissue gives aesthetically improved results in the patients with mammary hypertrophy or ptosis. It also reduces required flap size for reconstruction and permits discarding zones of poor perfusion, decreasing flap size-related problems such as partial flap loss or fat necrosis. Considering the high rate of bilaterality of breast cancer, it also provides a good opportunity for exploration and occult cancer diagnosis in such high risk group patients. Methods: We retrospectively reviewed 45 consecutive patients who underwent simultaneous breast reconstruction and contralateral reduction mammaplasty was performed about surgical technique, pathologic diagnosis, and subsequent treatment. Results: Three occult breast cancers were found in 45 patients(6.7%); one was microinvasive, and the other two were invasive carcinomas and their mean diameter was 1.2 cm. One patient underwent subsequent breast conserving mastectomy, adjuvant radiation and chemotherapy. The others underwent only radiation and hormone therapy. They were followed up for 10 to 42 months without evidence of recurrence or metastasis. Conclusion: Occult breast cancer diagnosed in reduction mammaplasty specimen will lead to good prognosis due to its early detection. Treatment options depend on pathologic finding, stage, marginal status, and the timing of diagnosis. We recommend adequate markings for orientation and margins, excision with sufficient margin, and confirmation by frozen biopsy for suspected lesions.

Ameloblastoma treatment varies based on the clinical, histopathologic, and radiographic characteristics. Aggressive surgical treatments, such as marginal or segmental resection, have traditionally been implemented, but some conservative surgical methods are also being introduced, including decompression, enucleation, or curettage. The aim of the present study was to evaluate the possibility of applying these conservative surgical treatments to ameloblastoma and to analyze the prognosis of the procedures and their healing aspects. Among all patients who visited our clinic (Department of Oral and Maxillofacial Surgery, Kyung Hee University Dental Hospital at Gangdong) from 2009 to 2017, three who had undergone conservative surgery were recruited. One of these three patients underwent both excision of the lesion and an iliac bone graft during the same procedure. In the other two patients, due to the size of the lesion, decompression was performed to reduce the size of the lesion, and then conservative surgical treatments followed. As shown in the cases of this study, patients were only treated with conservative surgical methods, such as decompression or enucleation. During the follow-up period, there were no recurrences. In conclusion, the use of conservative surgical treatment in ameloblastoma can be a reliable, safe, and successful method.
