Naevus on the top lip of a male patient

Watercolour drawing of a naevus which occurred on top lip of a male patient. Small multiple naevi occurred on various portions of the patient's body. There were others on the concha of the right ear, on the skin of the abdomen near the umbilicus, on the back of the left hand and several on the right foot and leg. There was also a large naevoid tumour in the popliteal space, which caused so much pain as to necessitate amputation through the thigh.
