Follicular induction in a case of molluscum contagiosum: possible link with secondary anetoderma-like changes?

Molluscum contagiosum (MC) can rarely show follicular neogenesis as a result of proliferation of virus-infected basal cells. We report a case of molluscum contagiosum showing multifocal areas of primitive follicular induction involving the adjacent surface epidermis. The underlying dermis showed histological features suggestive of secondary anetoderma. The pathogenetic mechanisms behind development of these microscopic features and the putative link between follicular induction and secondary anetoderma are explored. Awareness of this unusual phenomenon will be helpful in avoiding a misdiagnosis of a superficial basal cell (trichoblastic) carcinoma in such cases.
