Disseminated Cytomegalovirus Infection and Protein Losing Enteropathy as Presenting Feature of Pediatric Patient with Crohn's Disease / 대한소아소화기영양학회지

We report a pediatric patient admitted with abdominal pain, diffuse lower extremity edema and watery diarrhea for two months. Laboratory findings including complete blood count, serum albumin, lipid and immunoglobulin levels were compatible with protein losing enteropathy. Colonoscopic examination revealed diffuse ulcers with smooth raised edge (like "punched out holes") in the colon and terminal ileum. Histopathological examination showed active colitis, ulcerations and inclusion bodies. Immunostaining for cytomegalovirus was positive. Despite supportive management, antiviral therapy, the clinical condition of the patient worsened and developed disseminated cytomegalovirus infection and the patient died. Protein losing enteropathy and disseminated cytomegalovirus infection a presenting of feature in steroid-naive patient with inflammatory bowel disease is very rare. Hypogammaglobulinemia associated with protein losing enteropathy in Crohn's disease may predispose the cytomegalovirus infection in previously healthy children.

Endobronchial metastasis from testicular seminoma

To present a case of endobronchial metastasis from a seminoma mimicking a primary pulmonary mass on X-ray radiograph. Clinical Presentation and Intervention: A 27-year-old man presented with a 1-month history of hemoptysis. Thorax computerized tomography of the patient obtained at the level of the main right bronchi demonstrated a mass with a size of 7 x 6 cm and a peripheral lobulated nodule. Bronchoscopic examination showed narrowing and multiple nodules in the right upper and right intermediary lobar bronchi. Histopathological examination of bronchial biopsies and brushing confirmed endobronchial metastasis of the testicular seminoma. This case shows the prognostic significance of distinguishing endobronchial metastasis from primary lung carcinoma

Correlation of E - cadherin expression with clinicopathological parameters in breast carcinoma

To investigate the correlation between the E-cadherin [E-CD] expression and clinicopathological parameters including tumor grade, patient age, tumor size, necrosis, peritumoral lymphovascular invasion and lymph node status in breast carcinomas. The specimens were surgically obtained from 51 female patients with breast carcinoma between 1997 and 2001 in Karadeniz Technical University Medicine Faculty Farabi Hospital, Trabzon, Turkey. Histologic grading was according to the Bloom and Richardson methods. Tumors were classified as grade I [well differentiated], grade II [moderately differentiated] and grade III [poorly differentiated]. Necrosis was graded as [-], [+], [++] and [+++].Grade 1 breast carcinomas [n=17] showed greater immunoreactivity than grade 2 [n= 22] and grade 3 [n=12] carcinomas. None of the infiltrating lobular carcinomas expressed E-CD. Statistically, significant difference has been noticed between E-CD expression and the histological grade. In contrast, no association were found between E-CD expression and metastatic potential, tumor size, tumor necrosis and patients' age. Results in the present report suggest that E-CD expression in breast carcinoma is more related to histological type and differentiation grade than with metastatic potential, tumor size, tumor necrosis and patients' age
