Bortezomib-Induced Superficial Vasculitis in a Kidney Transplant Recipient: A Rare Case.

Bortezomib is a frequently administered immunosuppressive agent in kidney transplantation. A 30-year-old male kidney transplant recipient developed an atypical reaction on the left hand in terms of spider-like extensions, indicating erythematous inflammation along the superficial veins after bortezomib intravenous administration. The inflammation spontaneously resolved after three weeks with a bortezomib dose reduction. Nephrologists must be familiar with the potential cutaneous bortezomib-induced adverse effects.
