A regionwise comparative study of the extent of post punch graft surgical repigmentation in cutaneous achromia.

One hundred and ten cases of stable cutaneous achromia constituted the sample population, of which 67 were females and 43 males. Age ranged between 6 and 71 years. A total of 1742 grafts were placed over 177 lesions on 29 regions and the cases were followed up to a maximum period of 2 years. The extent of maximum pigment spread (MPS) was noted in different regions of the body. It was observed that exposed parts exhibited better outcome vis-a-vis covered and shadowed part. MPS ranged between 0 to 10 mm., with an overall average of approximately 5.5mm.
