Intussusception is the telescoping of a proximal segment of the gastrointestinal tract into an adjacent distal segment. This rare form of bowel obstruction occurs infrequently in adults. We report a case of small bowel intussusception in an adult male patient. We have also performed a literature review of this rare condition.

Sex steroids have been suggested to influence colorectal cancer (CRC) carcinogenesis. Also, exposure to exogenous hormones might contribute to its incidence. This study conducted to evaluate ER and PR expression as a prognostic factor in patients with CRC attending Sohag University Hospital (SUH) and Sohag Cancer Center (SCC). Materials and Methods: Tumor samples tested for Estrogen receptor (ER) / progesterone receptor (PR) expression using immunohistochemical staining (IHC). Association of this expression with overall survival (OS), disease-free survival (DFS) and progression-free survival (PFS) were evaluated. Results: Thirty out of 50 CRC tissues were evaluable for hormone receptor expression. Expression of both ER and PR was cytoplasmic. ER and PR expressions were 60% and 76.66%, respectively. There was a significant difference between loss of ER expression and depth of invasion (p= 0.01). Also, ER and PR negative expression cases were significantly at higher risk for progression (p= 0.03; 0.009 respectively). High levels of ER and PR expression were associated with higher cumulative PFS at one year and at the end of follow up time (p=0.01; 0..02 respectively); however this did not reach statistical significance on Cox proportional hazards regression analysis for progression or OS (p= 0.05; HR= 0.22; p=0.5; HR=0.67 respectively) for ER level and (p=0.07; HR=0.22; p=0.6; HR=0.72 respectively) for PR level. Conclusions: This study suggests that lower ER/PR expression levels were associated with more extensive CRC primary tumors and poorer prognosis. These data suggest that ER/PR expression might possess a prognostic value for CRC cases.

Chondroma is a benign cartilage-forming tumor which usually occurs in small bones of extremities but occasionally occurs in the brain. Usually, intracranial chondromas originate from skull base; however, chondroma of the falx cerebri is a very rare condition. We here report a rare case of falcine chondroma in a 19-year-old man who had normal physical examination without signs of any syndromic disorder. The neuroimaging findings were inconclusive, and the diagnosis was based on histopathological examination. The purpose of this paper is to raise attention about intracranial chondromas and suggest that chondroma must be ruled out in any patient presenting with masses arising from the falx.
