Anatomy
Upper Limb
You are asked to assess a 32 year old woman who presents with a five day history of fever and right arm swelling following a cat scratch. On examination you note she has supratrochlear lymphadenopathy. Regarding the supratrochlear lymph nodes, which one of the following statements is INCORRECT:
Answer:
The supratrochlear lymph nodes lie subcutaneously above the medial epicondyle, medial to the basilic vein. They drain the ulnar side of the forearm and the medial hand. Differential diagnosis for enlarged lymph nodes includes skin infections, skin malignancies and lymphoma.Supratrochlear and Infraclavicular Lymph Nodes

Supratrochlear Lymph Nodes
The supratrochlear lymph nodes lie subcutaneously above the medial epicondyle, medial to the basilic vein. They drain the ulnar side of the forearm and the medial hand. Differential diagnosis for enlarged lymph nodes includes skin infections, skin malignancies and lymphoma.
Infraclavicular Lymph Nodes
The 2 - 3 infraclavicular (deltopectoral) lymph nodes lie in the deltopectoral groove inferior to the clavicle, located superiorly and posteriorly to the axillary artery. They primarily drain the radial side of the upper limb. Lymphadenopathy here is highly suspicious for non-Hodgkin's lymphoma specifically, and for malignancy in general.
