Abstract :
The technique and results of surgery in 23 patients with skin dyspigmentation of the upper limb are presented. The study population was divided into two groups. Group A (n=15 patients) had hyperpigmented skin grafts in the palm or the palmar aspect of the digits. All patients underwent excision of the hyperpigmented grafts and coverage with split-thickness plantar skin grafts. The plantar grafts gave an excellent colour and texture match and all patients were satisfied with the result. Group B (n=8 patients) had post-burn hypopigmentation on the dorsal aspect of digits, hand or forearm. These patients underwent dermabrasion and thin split-thickness grafting harvested from the upper thigh or buttock. All grafts healed well with no residual hypopigmentation. However, the graft was slightly hyperpigmented when compared to the surrounding skin. Despite this complication, all patients were satisfied and considered this slight hyperpigmentation much better than the preoperative hypopigmentation. The pathogenesis of skin dyspigmentation and other treatment techniques are discussed.
