Dr. Aakanksha, Dr. Nita Kumari, Dr. Upasana Chauhan*

ABSTRACT

ILVEN or inflammatory linear verrucous epidermal neavus is a rare form of epidermal naevus which manifests due to somatic mutations, reflecting genetic mosaicism. It consists of hyperplasia of the normal components of the epidermis. Porokeratosis is a group of genetic disorders characterized by clonal proliferation of keratinocytes. Linear porokeratosis is a heterogeneous disorder of keratinization which may have sporadic or AD inheritance. The following case report sheds light on how the patient was diagnosed as ILVEN on the first visit, but after HPE, it was proved that the disease was linear porokeratosis. Of all variants, linear porokeratosis is especially prone to malignant degeneration with an increased risk of transformation to squamous cell carcinoma. Thus, it is essential to diagnose and treat such cases at the earliest to prevent further complications.
