A Case of Anaplastic Carcinoma Arising in Thyroglossal Cyst / 대한이비인후과학회지

A thyroglossal cyst is a common midline mass, which is related to the hyoid bone, and it may show signs of inflammation. Carcinoma arising in the thyroglossal cyst is rare, accounting for less than 1% of all thyroglossal cysts. Papillary adenocarcinoma is the most common histologic type(75-85%), whereas anaplastic carcinoma arising in thyroglossal cyst is extremely rare and there has been only two reported cases of it. Its prognosis is not established due to its rarity. We experienced a case of anaplastic carcinoma that occured in a thyroglossal cyst in a 63-year-old man and report it.

Two Cases of Pilomatrixoma in Neck / 대한이비인후과학회지

Pilomatrixoma or calcifying epithelioma is a rare benign tumor arising from hair cortex cell or hair follicle of sebaceous glands. But because of it's characteristic clinical presentation, practitioners should be aware of it's clinical feature. Most frequently, the tumor presents as a superficial located solitary, rock hard and noninvasive cutaneous mass on the face, neck or upper extrimities, that is often accompanied by reddish-blue discoloration of the overlying skin. It usually occurs within the first two decades of life. Recently, we experienced two cases of pilomatrixoma in the head and neck, which was diagnosed by histopathologic examination. The tumor was successfully removed by complete resection. So we report two cases with a review of literature.

Hemostatic Efficacy of Topical Application of Cold Hydrogen Peroxide in Adenoidectomy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Adenoidectomy is one of the most common procedures in the field of otolaryngology, and various hemostatic agents and techniques have been used for stanching the wound of adenoidectomy site. The aim of this study is to evaluate the hemostatic efficacy of topical application of cold hydrogen peroxide in adenoidectomy. MATERIALS AND METHOD: We randomly divided 120 candidates (aged 3-14 years) for adenoidectomy into 4 groups, and 3% hydrogen peroxide (3+/-2degrees C), 3% hydrogen peroxide (20+/-2degrees C), 0.05% epinephrine solution (3+/-2degrees C) and 0.05% epinephrine solution (20+/-2degrees C) were applied topically to each group respectively. The time consumed for bleeding control, and the hemostatic findings of adenoidectomy wound at 5 minutes after curretage, 6 hours after operation of each group were compared. RESULTS: The use of cold hydrogen peroxide significantly reduced intraoperative time when compared with uisng other hemostatic agents. And in the adenoidectomy site, it is found that the incidence of oozing and active bleeding decreased when cold hydrogen was applied. CONCLUSION: Cold hydrogen peroxide is a useful agent for hemostasis in adenoidectomy.
