Metastasis is most common in ?
lymphatic & hematogenous (blood) spread.
LYMPHATIC SPREAD It occurs more commonly with ?
Carcinomas
Emboli drained by systemic veins are carried to ?
Right side of the heart
Emboli drained by the Portal vein are carried to ?
liver causing liver metastases
Spread occurs early by blood and rarely (10%) by lymphatics.
Sarcoma
Spread occurs early by lymphatics then later by blood,
Carcinomas
LYMPHATIC SPREAD It occurs more commonly with ?
Carcinomas

In Transperitoneal spread In females, carcinoma of stomach, colon is ?
bilateral ovarian metastases (Krukenberg tumor)
In females, carcinoma of stomach, colon leads to ?
bilateral ovarian metastases (Krukenberg tumor)
Carcinoma in situ (CIS) represents a preinvasive stage of cancer and is characterized by severe or high grade epithelial dysplasia affecting whole thickness of epithelium without invasion of the basement membrane ?
CARCINOMA IN SITU
What is the Fate of CARCINOMA IN SITU ?
Progression into invasive carcinoma
Direct spread to a surface (skin or mucosa) leads to ulceration ?
malignant ulcer
Direct spread from one hollow organ to another adjacent one causes a ?
malignant fistula
