A patient presents in immediate care complaining of pain in his foot after stepping on a roofing nail "a couple of days ago." He is worried because he has a red streak running up his leg. The nurse suspects:
A) Cellulitis
B) A minor superficial skin irritation
C) Elephantiasis
D) Lymphangitis
Ans: D
Feedback: Lymphangitis is an acute inflammation of the lymphatic channels. It arises most commonly from a focus of infection in an extremity. Usually, the infectious organism is a hemolytic Streptococcus. The characteristic red streaks that extend up the arm or the leg from an infected wound outline the course of the lymphatic vessels as they drain. Option A is incorrect; cellulitis is caused by bacteria, which causes a generalized edema in the subcutaneous tissues surrounding the affected area. Option B is incorrect; a minor superficial skin irritation would not present with red streaks in the lymphatic channels. Option C is incorrect; elephantiasis is transmitted by mosquitoes, which carry a parasitic worm larvae. The parasites obstruct the lymphatic channels and this results in gross enlargement of the limbs.
