Foot of a man suffering from Hebra's sarcoma melanoides

Yetts, Walter Perceval

Watercolour drawing of the foot of a man subject of Hebra's sarcoma melanoides. The soles of the feet of the patient were uniformly roughened and scaly, and although somewhat dusky, did not show any papules or margined patches. At their borders it was as if he were wearing very low slippers the border being everywhere very definite and characterised by a number of small tubercules. Here the colour was almost black. It might be thought that the affected parts were contracted but this appearance was perhaps due to the oedema of the sound skin above which gave the latter an overhanging edge.
