A Case of Colonic Metastatic Malignant Melanoma of Unknown Origin / 대한소화기내시경학회지

A metastatic melanoma to the gastrointestinal tract is observed in 1.5~4.4% of all melanoma patients. However, colonic and rectal involvement is less common. A 72-year-old woman was admitted due to abdominal pain and poor oral intake for 20 days. She had a 3 x 4 cm-sized mass on her right inguinal area 4 month ago, which was diagnosed as a malignant melanoma of the inguinal lymph node on excision biopsy. A large exophytic mass with an irregular ulcerlated, whitish patch, erythematous surface was observed in the hepatic flexure during colonoscopy. A histology diagnosis of a metastatic melanoma was made by an optical microscopy examination of the biopsies obtained during the colonscopy, and palliative right hemicolectomy was performed on account of a potential intestinal obstruction. We report a case of a metastatic melanoma of the colon with a review of the relevant literature.

A Case of Turner's Syndrome(45,X/46,XX) Associated with Patent Ductus Arteriosus

We described a 65-year-old female of 45,X/46,XX Turner's syndrome associated with patent ductus arteriosus who was admitted due to exertional dyspnea and palpitation. This patient had not spontaneous mensturation and had a short stature without webbed neck and a sexual infantilism. Chromosomal aberrations cause primarily structural defects of cardiovascular system, and a variety of structural aberrations involving the X chromosome can cause partial or complete Turner's syndrome. In Turner's syndrome, bicuspid aortic valve or coarctation of aorta is frequently combined, also aortic root dilatation, partial anomalous venous drainage, hypoplastic left heart, ventricular septal defect, atrial septal defect has been reported. However, this patient had not abnormality in aortic valve and whole aorta. Patent ductus arteriosus in 45,X/46,XX Turner's syndrome have not been reported in Korea. We report this case with a brief review of the literature.
