A) Elephantitis
B) Chronic arterial insufficiency
C) Chronic lymphangitis

Ans: C
Feedback: The obstruction may be in the lymph nodes and the lymphatic vessels. Sometimes, it is seen in the arm after an axillary node dissection (eg, for breast cancer) and in the leg in association with varicose veins or chronic thrombophlebitis. In the latter case, the lymphatic obstruction usually is caused by chronic lymphangitis. Therefore options A, B, and D are incorrect.
