Granuloma annulare on herpes zoster scars in a Hodgkin's disease patient following autologous peripheral stem cell transplantation.

Various cutaneous lesions including granulomatous reactions may occur at sites of resolved herpes zoster infection. A 46-year-old man with Hodgkin's disease developed localized granuloma annulare lesions on herpes zoster scars 3 months after allogeneic peripheral stem cell transplantation. This is the first case of granuloma annulare localized on herpes zoster scars that developed following peripheral stem cell transplantation.
