title: Cutaneous and venous complications of pentazocine abuse.
abstract: A 55-year-old man with a two-year history of intramuscular pentazocine abuse had classical cutaneous findings as well as secondary venous thrombosis, which, to our knowledge, is previously undescribed. Histologic evaluation, including direct immunofluorescent microscopy, did not establish the mechanism of tissue destruction.
