Sweep 1.5 Flashcards
Fibroadenoma is the most common benign tumor of the female breast and usually appears in prepubertal girls and young women, with the peak prevalence in the third decade. They result from ———-. These tumors are ————– and comprised of both glandular epithelium and fibrous tissue. They usually appear as a solitary, discrete, freely movable nodule (1-10 cm in diameter). ———— is mandatory to verify its benign nature.

Carcinoma of the breast can be classified as ————- or ——— carcinoma (arising from glandular acini).
ductal carcinoma (arising from ductal epithelium)
lobular
Both ductal and lobular carcinoma have ——- precursor stages, termed ————- in which the neoplasm has not penetrated the ——— and thus has not invaded or infiltrated the ————–.

D. Portal hypertension
1. Increased pressure of portal blood flow can occur:
prehepatic (obstructive thrombi), intrahepatic (cirrhosis), and post hepatic (right sided heart failure).
D. Portal hypertension
- Consequences of portal hypertension:
1) ascites (excess fluid in peritoneal cavity-fluid is generally serous in nature), 2) esophageal varices, 3) splenomegaly, 4) hepatic encephalopathy, 5) hypogonadism.
