Case 1

A patient presented with chronic ulceration of the lower leg.

What is the diagnosis?

Venous ulceration.

What are the predisposing factors?

Ulcers in association with chronic venous insufficiency usually follow minor traum. Venous disease arises from calf muscle pump dysfunction. It is associated with prior deep venous thrombosis or cellulitis, incompetent (varicose) superficial or communicating veins and immobility.

What are the clinical features of this condition?

About 1% of the middle-aged and elderly population is affected by leg ulceration, most commonly in association with chronic venous sufficiency (45-80%).
Venous insufficiency results in aching, swollen lower legs that feel more comfortable when elevated. Signs may include:

Varicose veins
Chronic lymphoedema
Brawny stippled pigmentation
Stasis dermatitis (scratched, dry or weeping patches)
Atrophie blanche (scarring with prominent tortuous capillaries)
Lipodermatosclerosis (firm to hard induration)
Warty papillomatosis

A minor injury causes a punched-out ulcer that expands with an irregular brownish border. It may be painless or painful, dry or oozy. The most common site is the medial lower aspect of the calf especially over the malleolus. Multiple ulcers may occur.
