[Lymphography of the upper limb in malignant melanoma].

Owing to its technical difficulty and to an imperfect knowledge of its semiology, lymphography of the upper limb is rarely used.

Its main advantage in patients with palpable lymphadenopathy is that lymph node excision can be avoided in many cases provided the subjects are regularly followed up.
