Which of the following statements about neoplasms is false?
sarcomas tend to spreads hematogenously
skeletal muscle in an uncommon site of metastasis
the spleen is a common site of metastasis
carcinoma tends to spread by lymphatic invasion
In - situ (borderline) epithelial cancers display the cytologic features of malignancy without;
invasion of the basement membrane

mitosis
It codes for a variety of growth factors, receptors, and signal relay or transcription factors which act in concert to control entry into the cell cycle.
protooncogenes
tumor suppressor genes
growth factors
bcl-2
A two year old male presented with a 2 inch sized pouch like mass 2 feet from the ileocecal valve. It consists of all 3 layers of the bowel wall, with normal gastric and pancreatic tissues. These ectopic tissues are most likely:
