Unusual Presentation of Post Viteriolage Depigmentation without Superficial and Deep Cutaneous Injury

Abstract

A 45 years old male patient was seen with 6 weeks duration of depigmented macules on his body. Examination revealed multiple patterned, circumscribed, depigmented macules involving trunk and limbs. A few punctuate and linear depigmented macules were present on the right knee and the leg due to close contact with a few drops of the same acid. The patient claimed appearance of lesions after a family quarrel, due to acid exposure. Different acids were patch tested such as dilute sulphuric acid, concentrated sulphuric acid, glacial acetic acid, hydrochloric acid, dilute acetic acid, muriatic acetic acid and sodium bisulphate. Among all the tested acids hydrochloric acid showed positive results.
