Résumé
BACKGROUND: Sunitinib is an antiangiogenic tyrosine kinase inhibitor indicated in the treatment of metastatic renal cancer and gastrointestinal stromal tumours (GIST). We report a case of leg ulcer apparently triggered by this drug and we discuss the potential implication of the antiangiogenic effect of sunitinib in ulcer genesis. CASE REPORT: A 73-year-old woman with a history of deep venous thrombosis of the lower limbs was treated with sunitinib for renal cancer with hepatic and pulmonary secondaries. While on this treatment, she developed painful ulcers of the right lower limb, despite having never previously presented leg ulceration. On discontinuation of sunitinib, the lesions improved, and resumption of this drug, even at a lower dosage, resulted in relapse of her ulcers. DISCUSSION: Although questions may legitimately be asked about the contribution of the patient's venous condition, withdrawal of sunitinib followed by a positive rechallenge tend to suggest the role of this drug in recurrence of ulcers. Their recurrence despite the decreased dosage of the drug points to a nondose-dependent pathogenic mechanism.
