Chemotherapeutic agents may rarely cause discoloration and hyperpigmentation of the nails. We present a patient who developed blackish discoloration of nails also referred as melanonychia during six cycles of R-CHOP chemotherapy regimen (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) for the treatment of Non Hodgkin Lymphoma (NHL) follicular type. The patient developed blackish brown discoloration in all the nails. As suggested by previous literature evidence the melanonychia could be associated with cyclophosphamide and doxorubicin. According to the Naranjo causality assessment scale, we established that there was a 'probable' association of nail discoloration with the drug.
化疗药物很少会导致指甲变色和色素沉着过度。我们报告了一名在接受R-CHOP化疗方案(利妥昔单抗、环磷酰胺、多柔比星、长春新碱和泼尼松)六个周期治疗滤泡型非霍奇金淋巴瘤(NHL)期间出现指甲变黑(也称为甲下黑素沉着)的患者。该患者所有指甲均出现黑褐色变色。如先前文献证据所示,甲下黑素沉着可能与环磷酰胺和多柔比星有关。根据Naranjo因果关系评估量表,我们确定指甲变色与药物之间存在“可能”的关联。
