Extraskeletal Myxoid Chondrosarcoma of Larynx / 대한이비인후과학회지

Primary cartilaginous tumors of the laryngeal lesion are rare and it accounts for only 1% of laryngeal tumor pathology. They are most commonly located on the endolaryngeal surface of cricoid cartilage, and it is extremely rare to find them in vocal muscle lesion. In most cases, treatment of choice is based on surgical excision, and postoperative radiotherapy is typically recommended. We experienced a case of a 22-year-old young woman without underlying disease, presenting extraskeletal myxoid chondrosarcoma of vocal cord, especially in the vocal muscle. The patient underwent mass excision through suspension laryngoscope and radiation therapy.

A Case of Primary Nodal Type Marginal Zone B-Cell Lymphoma of the Intra-Parotid Lymph Node Mistaken to Primary Benign Parotid Mass / 대한이비인후과학회지

Marginal zone B-cell lymphomas are indolent lymphomas that arise from the memory B cells in the marginal zone of lymphoid tissue. They include mucosa-associated lymphoid tissue lymphoma, splenic marginal zone lymphoma, and nodal marginal zone lymphoma. These three subtypes share morphologic and immunophenotypic features, but can be distinguished by primary site at presentation. Recently, we experienced a rare case of primary nodal marginal zone lymphoma that arose from an intra-parotid lymph node. So we report this case with a review of literature.

Prevalence of Laryngeal Disease in South Korea: Data from the Korea National Health and Nutrition Examination Survey from 2008 to 2011

PURPOSE: The aim of this study was to evaluate the prevalence of Benign Vocal Fold Lesion (polyp, cysts, nodules) and Leukoplakia in Korea. MATERIALS AND METHODS: The data from the 2008 to 2011 Korea National Health and Nutrition Examination Surveys, which were cross-sectional survey of the civilian noninstitutionalized population of South Korea. A survey team that included an otolaryngology residents, nurses, and interviewers moved with a mobile examination unit and performed laryngologic interviews and examinations of vocal folds using rigid telescopic laryngoscopy on survey participants over 19 years old (n=19636). RESULTS: Laryngoscopic examination revealed normal results in 19251 (98.04%) of those included in the survey. Abnormal laryngoscopic findings were observed in 1.96% of the population examined, and vocal cord nodules were the most common abnormal finding. The prevalence of vocal cord nodules was 0.99-1.72%, the prevalence of vocal cord polyps was 0.31-0.55%, the prevalence of vocal cysts was 0.04-0.17%, and the prevalence of vocal cord leukoplakia was 0.07-0.21%. There was no significant correlation of linear trend of prevalence by year, and there were no significant differences in prevalence between males and females. CONCLUSION: This is the first nationwide epidemiologic study to assess the prevalence of Benign Vocal Fold Lesion (polyp, cysts, nodules) and Leukoplakia by both the Korean Otolaryngologic Society and the Ministry of Health and Welfare. The results of this large epidemiologic study provide valuable information regarding the prevalence of voice disorders and the management of laryngologic diseases.

Metastatic thyroid C-cell carcinoma in a beagle dog / 대한수의학회지

An adult beagle dog was presented with a cervical mass detected by palpation and computed tomography. Fine needle aspirates revealed numerous epithelial cells with plasmacytoid appearance and frequent naked nuclei. Histologically, the mass consists of multiple packets of neoplastic cells and extensive areas of necrosis and fibrosis. Neoplastic cells were also found in submandibular lymph nodes. Immunohistochemistry showed that neoplastic cells were positive for calcitonin and negative for thyroglobulin. Based on these findings, the cervical mass was diagnosed as thyroid C-cell carcinoma. Almost one year after the surgical excision, the dog remains healthy without any symptom of recurrence or metastasis.

A Case of Solitary Angiokeratoma of the Oral Tongue Tip / 대한이비인후과학회지

Angiokeratoma is a rare, cutaneous disorder that typically manifests as multiple lesions and is often associated with a number of metabolic disorders. Although solitary cutaneous forms have been reported, localized lesions within the oral tongue have not been described so far. We report a 16-year-old male with a solitary pigmented lesion of his oral tongue tip. The lesion was a mixture of purple and white in color with a granulomatous appearance. Histopathological examination of the lesion obtained by excisional biopsy showed features consistent with angiokeratoma. We report a case of solitary angiokeratoma of the oral tongue tip and review the clinical and pathologic features of this unusual condition.

Penetrating Carotid Artery Injuries Treated by an Urgent Endovascular Stent Technique: Report of Two Cases / 전남의대학술지

Penetrating neck injuries are potentially dangerous and require emergent management because of the presence of vital structures in the neck. Penetrating vascular trauma to zone I and III of the neck is potentially life-threatening. An accurate diagnosis and adequate surgical intervention are critical to the successful outcome of penetrating trauma in the neck. We experienced some cases with externally penetrating injuries in neck zone II in which the patients were confirmed to have the presence of large vessel injuries in neck zones I and III. Here we report on the endovascular stent techniques used in two cases to address penetrating carotid artery injuries and review the literature.

A Case of Papillary Carcinoma in Thyroglossal Duct Cyst / 대한갑상선학회지

The malignant neoplasm of thyroglossal duct cyst (TGDC) is a rare tumor and is mostly revealed accidently in the course of histologic examinations after surgery. The most common histopathologic type is a papillary carcinoma. We experience a 25-year-old young woman of papillary carcinoma in thyroglossal duct cyst and the position of pyramidal lobe was unusual. She was treated by Sistrunk's operation with total thyroidectomy. We report this case with a review of literature.

Migration of Fish Bone Following Penetration of the Submandibular Gland Presenting as a Neck Mass / 대한이비인후과학회지

An ingested fish bone presenting as an unresolving inflamed neck mass is rare. The purpose of this article was to describe the clinical and microscopic features of a foreign-body granuloma in submandibular region that resulted from a fish bone embedded in the floor of mouth. A 45-year-old male patient complained of a hard mass in submandibular region. Computer tomography allowed that localize of the lesion and the fish bone penetrating a submandibular gland. We successfully operated on the patient to excise the mass. A microscopic examination showed a anewly-formed granuloma, composed of lympocytes and epithelioid cells, and some microabscess with neurophiles. The final diagnosis was a foreign-body granuloma with a fish bone. Even though foreign-body granulomas in submandibular region are rare lesions, surgeons should be familiar with their features and include them in the differential diagnosis of tissue masses.
