Genital involvement in porokeratosis (PK) is a rare occurrence even in disseminated forms. We encountered three patients who had porokeratosis affecting only the genital area. Two of them were male with involvement of the penis and scrotum and only the scrotum respectively. The lady with vulvar involvement is a hitherto unreported instance of porokeratosis confined to female genitalia. None of the cases were very easy to diagnose clinically but biopsies proved confirmatory. The male patients were advised light electrocautery under local anesthesia while the female patient underwent surgical excision. No malignant change has been reported in them till date.

Epidermolysis bullosa pruriginosa, a genetic mechanobullous disease, is characterized by pruritus, lichenified or nodular prurigo-like lesions, occasional trauma-induced blistering, excoriations, milia, nail dystrophy and albopapuloid lesions, appearing at birth or later. Scarring and prurigo are most prominent on the shins. Treatment is unsatisfactory. We report three such cases: two of them first cousins, are described with history of blisters since childhood, followed by intensely pruritic lesions predominantly on the shins, and dystrophy of toenails, but no albopapuloid lesions or milia. Intact blisters were present in one case, and excoriations were seen in the other two. All of them showed encouraging response to cryotherapy.

The true existence of naevoid psoriasis and inflammatory linear verrucous naevus as distinct entities has been a debatable issue. Each has been opined to be a variant of the other. Considerable clinical and histological resemblance is seen between the two conditions. We describe three cases which attempt to throw more light on this issue.
