MADAM, Acrokeratosis verruciformis (AKV) is a rare autosomal dominant or sporadic genodermatosis. Affected individuals demonstrate asymptomatic, flat-topped, skin-coloured papules on the dorsal hands and feet. On histological examination, AKV demonstrates marked compact orthokeratosis, hypergranulosis, mild regular acanthosis and variable 'church spire' papillomatosis, without viral cytopathic changes, parakeratosis, acantholysis or dyskeratosis. It has long been hypothesized that AKV is allelic to Darier disease. However, the literature contains just two reports of genetic analyses of patients with AKV, 1,2 only one of which documented mutations in ATP2A2, which is the gene defect in Darier disease. 1 That report included one family with a novel P602L mutation in ATP2A2.Here, we present the second report of ATP2A2 mutations in AKV, in this case resulting in an A698V codon change which has never been described in patients with either AKV or Darier disease. An 11-year-old Afghani boy presented with a 6-year history of asymptomatic bumps on the hands and feet. He had been diagnosed with verruca plana and treated with cryotherapy, cimetidine and topical tretinoin, imiquimod and salicylic acid, none of which resulted in significant improvement. Past medical history was unremarkable. There was no family history of similar lesions, Darier disease or consanguinity. Physical examination revealed 1-4-mm verrucous, flat-topped papules over the dorsal hands, wrists, feet and ankles (Fig. 1). The remaining physical examination was normal, including palms and nails. A shave biopsy from the hand taken 4 years earlier at an another institution, and a repeat shave biopsy (Fig. 2) from the hand both demonstrated marked hyperkeratosis overlying a slightly acanthotic epiderm...
