Research paper thumbnail of Hypogenetic lung syndrome with anomalous venous return to the left inferior pulmonary vein: multidetector row CT findings

This is the first report of hypogenetic lung syndrome with anomalous venous return to the left inferior pulmonary vein.

Research paper thumbnail of Well-differentiated fetal adenocarcinoma of the lung: Cytomorphologic features on fine-needle aspiration with emphasis on use of β-catenin as a useful diagnostic marker

Diagnostic Cytopathology, 2006

Well-differentiated fetal adenocarcinoma (WDFA), also known as low grade adenocarcinoma of the fe... more Well-differentiated fetal adenocarcinoma (WDFA), also known as low grade adenocarcinoma of the fetal lung type, is a rare pulmonary neoplasm now considered to be a variant of lung adenocarcinoma rather than a type of pulmonary blastoma. Upregulation of the Wnt signaling pathway with subsequent aberrant nuclear/cytoplasmic beta-catenin expression has been recently described in these tumors providing a possible pathogenetic role for this gene in WDFA. We describe the cytomorphologic findings of a case of WDFA in a 36-yr-old female patient and emphasize the diagnostic utility of aberrant nuclear/cytoplasmic expression of beta-catenin as an adjunct to the correct preoperative recognition of this tumor on aspiration cytology.

Nineteen of 39 CVID patients (48%) had GI complaints. The most common symptom was chronic diarrhea (28%). In endoscopic examination of small intestines, 15 patients had no abnormal finding. Duodenal biopsy revealed villous atrophy in eight and nodular lymphoid hyperplasia in three patients. There was no statistically significant difference between patients with and patients without duodenal villous atrophy regarding the presence of chronic diarrhea, anemia, and absolute CD4 + T cells. In three patients, biopsies of the colon showed chronic noncrypt-destructive colitis. GI problems pose a high morbidity to CVID patients and are second only to respiratory complications. CVID patients are at increased risk of infectious and inflammatory conditions in the GI tract. Early diagnosis of these complications improves the quality of life and well-being of patients.
