Concurrently, his BP, characterised by blistering skin lesions, was managed with corticosteroids, azathioprine and methotrexate, though full control of disease activity was difficult. Following salvage RT and androgen deprivation therapy, his prostate-specific antigen (PSA) levels and BP improved significantly, leading to prostate cancer remission and near resolution of his BP.The patient continues methotrexate, with stable PSA and only minor localised BP activity. The temporal relationship between his prostate cancer and BP, including their simultaneous onset, recurrence and remission, suggests a possible paraneoplastic link.
