Brentuximab vedotin (BV) is an antibody-drug conjugate, consisting of a CD30-directed antibody, conjugated by a protease-cleavable linker to a microtubule disrupting agent auristatin E (MMAE). Although the safety datasheet of BV does not warn of severe toxic effects of extravasation, we report a third case of a patient with anaplastic large cell lymphoma who developed severe epidermal necrosis after extravasation. The reason for what happened could be attributed to the fact that MMAE belongs to the group of vinca alkaloids so it should be handled like other tissue-necrotising chemotherapeutics. Reporting of all cases of extravasation involving new conjugated chemotherapeutic drugs is of the utmost importance to be able to develop updated guidelines. Hospital pharmacists can provide information on how to manage extravasation, assess the potential risk, and have a crucial role in drafting hospital protocols.
