Primary malignant melanoma without melanosis of the colon: Nam Hee Yi, Sang Heon Lee, Sang Heon Lee, Ji Hyun Kim, Sam Ryong Jee, Sang Yong Seol; Intest Res 2019;17(4):561-564. Published online August 5, 2019; DOI: https://doi.org/10.5217/ir.2019.00020

Primary malignant melanoma (PMM) of the gastrointestinal tract is rare. Reported cases of PMM of the lower gastrointestinal tract typically describe anal and rectal involvement rather than colonic lesions. This report describes a rare case of a 50-year-old woman with PMM originating in the colon. The patient presented to Inje University Busan Paik Hospital with a 3-day history of blood-tinged stools. She underwent colonoscopy for a diagnosis of hematochezia. The colonoscopic examination revealed a large-sized semi-pedunculated sigmoid colon polyp with a reddish-colored mucosal surface. Endoscopic mucosal resection was performed, and the final histopathological findings were consistent with a diagnosis of malignant melanoma. Systemic work-up was performed for assessment of metastasis and to identify the primary tumor considering the high metastatic rate of gastrointestinal malignant melanoma; however, no other malignant lesion was detected. Thus, she was diagnosed with colonic PMM. She underwent laparoscopic low anterior resection and lymph node dissection and has been recurrence-free for > 2 years.

IBD

Duodenal amyloidosis secondary to ulcerative colitis: Seung Woon Park, Sam Ryong Jee, Ji Hyun Kim, Sang Heon Lee, Jin Won Hwang, Ji Geon Jang, Dong Woo Lee, Sang Yong Seol; Intest Res 2018;16(1):151-154. Published online January 18, 2018; DOI: https://doi.org/10.5217/ir.2018.16.1.151

Amyloidosis is defined as the extracellular deposition of non-branching fibrils composed of a variety of serum-protein precursors. Secondary amyloidosis is associated with several chronic inflammatory conditions, such as rheumatologic or intestinal diseases, familial Mediterranean fever, or chronic infectious diseases, such as tuberculosis. Although the association of amyloidosis with inflammatory bowel disease is known, amyloidosis secondary to ulcerative colitis (UC) is rare. A 36-year-old male patient with a 15-year history of UC presented with nausea, vomiting, and abdominal pain. He had been treated with infliximab for 6 years. At the time of admission, he had been undergoing treatment with mesalazine and adalimumab since the preceding 5 months. Esophagogastroduodenoscopy showed mucosal erythema, edema, and erosions with geographic ulcers at the 2nd and 3rd portions of the duodenum. Duodenal amyloidosis was diagnosed using polarized light microscopy and Congo red stain. Monoclonal gammopathy was not detected in serum and urine tests, while the serum free light chain assay result was not specific. An increase in plasma cells in the bone marrow was not found. Secondary amyloidosis due to UC was suspected. The symptoms were resolved after glucocorticoid therapy.

Clinical features of Crohn's disease in Korean patients residing in Busan and Gyeongnam: Eun Ji Lee, Tae Oh Kim, Geun Am Song, Jong hun Lee, Hyung Wook Kim, Sam Ryong Jee, Seun Ja Park, Hyun Jin Kim, Jong Ha Park; Intest Res 2016;14(1):30-36.

<b>Background/Aims</b><br/>

Crohn's disease (CD) is a chronic inflammatory bowel disease that presents with variable features and repeated disease aggravation. The incidence of CD is increasing in Korea. We evaluated the clinical features of CD in a study population in Busan and Gyeongnam, Korea.

Methods

A hospital-based analysis included 619 patients diagnosed with CD between March 1986 and February 2013 from seven tertiary care hospitals in Busan and Gyeongnam. Individual case records were reviewed with regard to age at diagnosis, sex, disease location, disease behavior, and medical and surgical treatments received during the follow-up period.

Results

The cumulative frequency of patients diagnosed with CD revealed a continued increase in the number of cases reported yearly. The male-to-female ratio was 2.5:1 and the median age at diagnosis was 24 years. At diagnosis, 114 (18.4%) had isolated small bowel disease, 144 (23.3%) had isolated colonic disease, and 358 patients (57.8%) presented with disease in the small bowel and colon. The number of patients presenting with stricturing or penetrating disease behavior was 291 (47%) at the final evaluation. In total, 111 (17.9%) patients underwent intestinal resections.

Conclusions

A continued increase in the number of patients diagnosed with CD was found in Busan and Gyeongnam as observed in other regions. We report results similar to that of other Korean studies in terms of sex distribution, age, and location of disease.

A Case of Mixed Hyperplastic-adenomatous Rectal Polyp with Composition of Invasive Adenocarcinoma: Hyo Rim Seo, Ji Hyun Kim, Soo Jin Jung, Yun Jung Choi, Choong Heon Ryu, Kwan Sik Park, Seoung In Ha, Eun Uk Jung, Sang Heon Lee, Sung Jae Park, Jung Sik Choi, Sam Ryong Jee, Youn Jae Lee, Sang Young Seol; Intest Res 2012;10(3):295-299. Published online July 31, 2012; DOI: https://doi.org/10.5217/ir.2012.10.3.295

Abstract PDF: Epithelial colon polyps are largely divided into hyperplastic and adenomatous polyps. Adenomatous polyps are premalignant lesions, whereas hyperplastic polyps are regarded as benign lesions. However, this histological classification has been blurred, as cases of malignant changes in hyperplastic polyposis, mixed hyperplastic adenomatous polyps (MHAPs), and serrated adenomas in the colon have been reported. Rare cases of MHAP have been reported, and are mainly found at the proximal colon with a relatively large size. MHAPs seem to be an intermediate stage of the hyperplastic polyp-adenoma sequence or a collision tumor. Here, we report on a case of a single polyp in the rectum diagnosed with a MHAP combined with an invasive adenocarcinoma. (Intest Res 2012;10: 0-299)

The Characteristics of Colonoscopic Findings in Differentiating Crohn's Disease from Intestinal Tuberculosis: In Soo Je, Sang Hyuk Lee, Eun Uk Jung, Myoung Joo Kang, Sang Won Park, Paul Choi, Ji Hyun Kim, Sung Jae Park, Sam Ryong Jee, Eun Taek Park, Youn Jae Lee, Sang Yong Seol; Intest Res 2007;5(2):158-164. Published online December 30, 2007

Abstract PDF: Background/Aims
The incidence of Crohn's disease (CD) is on the increase in Korea. The differentiation of Crohn's disease from intestinal tuberculosis (IT) is difficult. The aim of this study is to determine the characteristics of colonoscopic findings and factors that differentiate CD from IT. Methods: A total of 136 patients who were diagnosed with CD or IT at the Busan Paik Hospital from January 1995 to May 2005 were included in this study. We analyzed endoscopic findings, clinical characteristics and histological findings of 75 patients with CD and 61 patients with IT retrospectively. Results: For patients with IT, 18 (58.1%) of the patients had circular ulcers. For patients with CD, 27 (42.1%) of the patients had transverse ulcers, 18 (28.1%) of the patients had longitudinal ulcer, and 19 (29.6%) of the patients had both types of ulcers. The involvement of the ileocecal valve was noted in 18 (58.0%) of the patients with CD and in 37 (57.8%) of the patients with IT. The involvement of the rectum or anus was noted in 24 (51.5%) of the patients with CD and one (3.2%) patient with IT. Conclusions: According to previous studies, the presence of an ulcer was important to differentiate CD from IT. However, the presence of an ulcer was not a significant differentiating factor in our study. On colonoscopic findings, involved segments, an aphthous ulcer, cobblestone appearance, involvement of the rectum or anus and mucosal bridge should be observed carefully. (Intest Res 2007;5:158-164)
