Primary lymphoma of the thyroid is a relatively rare malignant thyroid neoplasm. It is known to be frequently associated with Hashimoto's thyroiditis. The clinical presentation includes an enlarging neck mass, accompanied by dysphagia, dyspnea or hoarseness, with its most common histologic type being the diffuse large B cell non-Hodgkin's lymphoma. Recently, we experienced a case of a primary thyroid lymphoma associated with Hashimoto's thyroiditis in a 60-year-old woman, who presented with an anterior neck mass. We present this case with a review of the literature.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

A newly developed third generation enzyme immunoassay(Lucky HCD 3.0 EIA) for hepatitis C virus(HCV) antibodies was added with the envelope(E1E2)/NS4 fusion proteins and expanded NS5 proteins as well as the core/NS3 fusion proteins. Authors evaluated the HCD 3.0 EIA with the previously available second generation EIA(HCD 2.0) in 10,435 Red Cross blood donors. Among 10,435 donors who were screened for the presence of HCV antibodies by HCD 2.0 assay, 22(0.21%) sera were repeatedly reactive. All of these sera were tested for further testing. Only 13 of all tested sera were reactive by HCD 3.0 EIA, and nine sera were not reactive. Nine of 13 HCD 3.0 positive sera were reactive by recombinant immunoblot assay(Lucky-Confirm). Also seven of these 13 sera had detectable HCV genomic RNA by reverse transcriptase-polymerase chain reaction(RT-PCR). None of nine HCD 3.0 negative samples had detectable immunoblot assay and HCV genomic RNA. It is concluded that the new HCV EIA can decrease a significant false positivity of second generation EIA in a blood donor population. This new assay correlates well with detection of HCV-RNA by RT-PCR and identifies donors who are truly infected.

Fibrous histiocytomas (FHs) are skin or deep tissue tumor that include a heterogenous group of tumors. The common origin of these tumors are a histiocyte and these tumors are composed of fibroblasts and histiocytes. FHs commonly occurs in the sun-exposed skin and subcutaneous tissue, but its incidence in the head and neck is rare. We experienced a case of FH in the infratemporal fossa and parapharyngeal space in a 29-year-old woman. The patient showed hyperesthesia in the right chin and some facial swelling. We could successfully remove the mass without sacrifice of important structures by infratemporal fossa approach with osteotomy of mandible.

PURPOSE:Recently it became obvious that some early cancers which appeared to be polyp lesions had actually originated from depressed-type lesions. The aim of this study was to clarify both the characteristics of depressed- type early colorectal cancers compared with protruded- or flat-type ones and the significance of a subclassification of depressed-type early cancers. METHODS:The authors experienced 248 early colorectal cancers from 1996 to 2000. We classified those cancers into protruded, flat, and depressed types based on growth and development. Further, we used Kudo's classification to subclassify the depressed-type cancers into three sub-types, IIc, IIa+IIc, and Is+IIc. We analyzed the 248 cases with emphasis on size, type, sub-type, and submucosal cancer (sm) rate. RESULTS:The sm rate of the depressed cancers was 81.8% (18/22) and was significantly higher than those of the protruded (30.5%) or the flat (38.5%) types (P<0.05). The sm rate of the depressed lesions not larger than 10 mm was 70% (7/10) and that of the lesions from 11 mm to 20 mm was 91.7% (11/12); there were no depressed cancers larger than 20 mm in diameter. The sm rate of the type IIa+IIc plus type Is+IIc lesions was higher than that of type IIc lesions (93.3%, 14/15 vs. 57.1%, 4/7). Endoscopic resection was done in 74.2% of all early colorectal cancers. CONCLUSIONS:The sm rate of depressed-type early colorectal cancers was 82%, and no depressed cancers were larger than 20 mm in diameter, suggesting that by the time a depressed-type cancers had become larger than 20 mm in size, it had already progressed into an advanced cancer. Thus, it is very important to detect depressed-type cancers in an early stage. Moreover, it is imperative to differentiate type IIa+IIc and type Is+IIc from polyp lesions and to manage them cautiously because their sm rate is higher than that for type IIc lesions.
