Nevus Depigmentosus Treated with Suction Blister Grafting: Follow-up After 10 Years
A 15-year-old female student presented with a hypopigmented asymptomatic macule on the left half of the upper lip [] slightly extending to the left cheek, since birth. The lesion measured 2 × 5 cm. On pressing the lesional border, there was no disappearance of the hypopigmentation. Wood's lamp examination showed an off-white accentuation. Examination of other areas of the skin did not reveal any similar lesions or any other type of skin lesions and the other systems particularly the skeletal and nervous system were within normal limits. Her investigation revealed normal blood counts; liver function test (LFT), renal function test (RFT), clotting profile, and test for HIV were negative.\nIn March 2002, suction blister grafting was performed on her after taking informed consent. Multiple blisters were raised on the left thigh using a suction blister technique described by Gupta et al.[] The recipient site was dermabraded with the loop electrode of radiosurgery equipment. Then, the blister roof from the thigh was removed with the help of iris scissors, transferred on to a glass slide; the edges were trimmed to fit the shape of the recipient area and then applied on to the recipient ND site []. When the dressing was removed after 48 hours, the grafts were well taken. The patient was put on topical PUVASOL (Psoralen plus UltraViolet-A of SOLar origin) after the grafts fell off and the resultant pigmentation was satisfactory at a follow-up after 1 month.\nThe patient followed up in the clinic after a gap of 10 years in May 2012, and on examination, it was found that the pigmentation achieved with suction blister grafting was well maintained [], though there were a few areas of patchy hyperpigmentation toward the angle of the lip on the left side.
