ABSTRACT
Anisakiasis is a parasitic disease caused by an infection of Anisakinae larvae. It occurs when the live larvae are introduced to the human gastrointestinal tract by eating infected raw fish. The endoscopic features of the gastric mucosa adjacent to the worms include redness, edematous, which are sometimes hemorrhagic and erosive. Gastric anisakiasis forming submucosal tumor, due to unobserved endoscopy, larva is very rare. 2 cases of submucosal tumors caused by gastric anisakiasis were found by endoscopic examination. The well demarcated mass lesion was seen in the submucosal layer of the stomach using endoscopic ultrasonography, and confirmed by laparoscopic wedge resection.

Leptin, which is a plasma protein produced by the obese gene, is expressed and secreted by adipocytes. The clearance of lepdn from the circulation is unknown. But, markedly elevated serum leptin concentrations have recently been reported in patients with chronic renal failure. The purpose of the present study was to investigate plasma leptin concentration of patients with chronic renal failure and evaluate the factors affecting plasma leptin levels. Plasma leptin, insulin, and body mass index were determined in 34 patients with chronic renal failure and 55 control subjects. The plasrna leptin concentrations were not significantly different between patients with chronic renal failure and control subjects (9.4+/-11.8 vs 4.9+/-4.2ng/ml, P>0.05). The serum leptin concentrations were not significantly higher in both male and female CRF patients compared with control subjects (3.96+/-5.72 vs 2.48+/-1.65, P=0.1947, 17.07+/-14.02 vs 7.49+/-4.63ng/ml, P=0.07, respectively). And, there was no significant correlation between serum creatinine and plasma leptin. However, there was significant correlation between plasma leptin concentration and insulin level (P<0.05). We fit a multiple linear regre- ssion analysis with plasma leptin level as the dependent variable in CRF. Sex (male vs female) (P< 0.001) and insulin (P=0.004) were independently associated with plasma leptin level in CRF. These results suggested that plasma leptin level was regulated or affected by multiple factors inclu- ding sex and insulin resistance. Additional study is required to evaluate relationship between plasma leptin and insulin resistance in chronic renal failure.

Granular cell tumors (GCT), previously termed granular cell myoblastorna, was first described as a myoblastic myoma of the tongue in 1926 by Abrikossoff and has been reported in many different locations throughout the body. In 1931, Abrikossaff described the first granular cell tumor of the esophagus. The gastrointestinal tract is one of the more uncommon locations for granular cell tumors. Until recently, granular cell tumors had been considered rare but, the incidence of granular cell tumors has been slowly raising since endoscopy has been used more commonly as a diagnostic tool. In this study, we report three cases of esophageal granular cell tumors which were successfully diaganosed by an esophagoscopy and an endoscopic ultrasonography and confirmed using an endoscopic esophageal mucosal resection (EEMR).

Lipoma is a benign fatty tumor that can arise in any location of the body where fat is present. It is found most commonly in the upper half of the body, particularly the head and neck, shoulders, and back. A mass in the antero-inferior part of the neck may be initially thought to be thyroid masses and then other cervical masses should be considered. Ultrasongraphic examination of benign lipoma demonstrates solid and echogenic mass and may differentiate nonthyroid from thyroid masses. Although the location of tumors, its consistency, and its motion with deglutition, seperation from the thyroid on sonographic examination, all pointed to nonthyroidal origin, did not rule out a possible mass that isolated from the lobes of the thyroid. Fine needle aspiration and biopsy can provide clear answer.We herein report a case of anterior cervical mass in a 48-yr-old male patient presenting a non-tender, slightly hard and nodular mass slowly growing for several years and moved with swallowing, and diagnosed his case as benign lipoma using thyroid scan and ultrasonography. When we encounter patients with anterior neck mass, we should consider benign lipoma mimicking diffuse goiter.
