Question 1#

A cutaneous malignancy of the anterior abdominal wall 2 inches above the umbilicus will drain to which lymphatic basin?

A. Umbilical
B. Axillary
C. Retroperitoneal
D. Inguinal

Correct Answer is B

The lymphatic drainage of the anterior abdominal wall is principally to the axillary nodal basin and the inguinal nodal basin. The area of demarcation is roughly the arcuate line (semilunar line of Douglas) at the level of the anterior iliac spine.
