Sir,

We are grateful to our esteemed colleagues for their comments ^[1] on our article ^[2] and for the interest shown.

We would however like to assert that the patient described by us had an epidermolytic acanthoma of the vulva, a well-described entity, ^[3],[4],[5] in a linear pattern rather than an adult-onset verrucous epidermal nevus, as suggested, for the following reasons:

1. The articles cited ^[6],[7],[8] in the letter refer to adult-onset verrucous and inflammatory epidermal nevi and not to epidermolytic verrucous epidermal nevus. None of the reported cases had features of epidermolytic hyperkeratosis, a distinctive feature seen on histology in our patient. However, we agree that the clinical features were indistinguishable from verrucous and inflammatory linear epidermal nevi.
2. Epidermolytic verrucous epidermal nevus usually occurs at birth or in young children. ^[9],[10]
3. The onset in adulthood, the clinical features, site of occurrence and histologic features of the lesion seen in our patient were consistent with the diagnosis of epidermolytic acanthoma. ^[3],[4],[5] The linear pattern of presentation was unusual and hence the case was reported in the journal.
