RESUMEN
Primary colorectal choriocarcinoma is a rare neoplasm. Only 19 cases have been reported worldwide, most of which involved adenocarcinomas. The prognosis is usually poor, and the standard therapy for this tumor has not been established. A 61-year-old woman presented with constipation and lower abdominal discomfort. She was diagnosed with primary adenocarcinoma with focal choriocarcinomatous differentiation in the sigmoid colon and liver metastasis. Because the serum beta-human chorionic gonadotropin level was not significantly elevated, and because only focal choriocarcinomatous differentiation was diagnosed, we selected the chemotherapy regimen that is used for the treatment of metastatic colorectal adenocarcinoma. The patient survived for 13 months after the initial diagnosis. This is the first case in Korea to assess the suppressive effects of the standard chemotherapy for colorectal adenocarcinoma against coexisting colorectal choriocarcinoma and adenocarcinoma.

Acute appendicitis is common in all age groups. Although many patients with acuteappendicitis present with migrating abdominal pain, the initial presentation can be atypical and nonspecific. Unusual manifestations can lead to diagnostic delay, which is associated with increased morbidity and mortality. Colonoscopic findings suggestinga diagnosis of asymptomatic appendicitis include hyperemia and bulging at the appendiceal orifice area with surrounding mucosal edema, and drainage of pus from the appendiceal orifice. We report a case of asymptomatic perforated appendicitis and periappendiceal abscess that presented as a subepithelial sigmoid colon lesion at screening colonoscopy. On colonoscopy, a subepithelial lesion with pustular drainage surrounded by hyperemic mucosa was seen at the sigmoid colon. Computed tomography revealed appendicitis and a periappendiceal abscess with adjacent sigmoid colon wall thickening. The patient underwent an appendectomy, with a final diagnosis of a perforated appendicitis with a periappendiceal abscess.

We have experienced a case of dup (3q) syndrome in the neonate who had a multiple congenital anomalies of hypertrichosis, hypertelorism, upslanting palpaberal fissures, anteverted nostrils, long philtrum, micrognathia, downturned corners of the mouth, highly arched palate, short, webbed neck, clinodactyly, rocker-bottom feet, dermal sinus. Cytogenetic studies showed a duplication 3q21-->qter regions. Chromosome study of relatives is extremely important for counseling because only 25% of cases represented de novo duplications. We reported the case with the review of the associated literatures.
