[Unilateral swelling of the leg].

Unilateral swelling of the leg is a common problem in general practice. The spectrum of underlying diseases is broad and does include venous and lymphatic disorders but also less frequent diseases such as Baker cysts and Sudeck's dystrophia. In the majority of cases a diagnosis can be made based on the patients history, the clinical findings and some specific laboratory and/or instrumental investigations. Selected cases however, require the attention of the vascular specialist.
