Ulcers associated with the swollen leg.

A number of disparate conditions may produce ulcers in swollen legs. The most frequent causative condition is venous stasis; other causal disorders are lymphatic obstruction, mixed vascular anomalies, benign and malignant neoplasms and a number of miscellaneous conditions. Careful attention to cutaneous signs of these conditions may be helpful in arriving at an accurate diagnosis and appropriate therapy.
