Docetaxel belongs to the taxane group of chemotherapeutic agents used in the management of various malignant diseases. Nail changes as a complication of such treatment are observed in about 44%. Subungual haemorrhages (SH), are very rare following docetaxel therapy and only a few cases have been previously reported.
An 80-year-old man suffering from prostate adenocarcinoma was treated with a 3-weekly cure of docetaxel started 3 months earlier. Nail changes occurred after the 5th cycle of docetaxel. Clinical examination revealed orange discoloration of the nail plates, subungueal haemorrhages (SH) and onycholysis involving nails of all the digits and toenails of both hands and feet. These features were highly suggestive of nail toxicity following docetaxel therapy.
Nail changes secondary to Taxane chemotherapy includes nail bed dyschromia, onycholysis, red or orange Beau's lines and subungueal hyperkeratosis. SH, as reported in this case, is related to the cumulative dose of docetaxel and should not be attributed to other systemic diseases. Clinicians should recognize this complication to avoid abusive treatment or investigations and inform the patients about the possibility of nail changes secondary to taxane drugs.
多西他赛属于用于治疗各种恶性疾病的紫杉烷类化疗药物。约44%的患者会出现指甲变化这种治疗并发症。甲下出血(SH)在多西他赛治疗后非常罕见,此前仅有少数病例报道。
一名80岁前列腺腺癌男性患者,3个月前开始每3周进行一次多西他赛治疗。多西他赛第5个周期后出现指甲变化。临床检查发现所有手指和脚趾甲的甲板呈橙色变色、甲下出血(SH)和甲分离。这些特征高度提示多西他赛治疗后的指甲毒性。
紫杉烷化疗继发的指甲变化包括甲床色素沉着异常、甲分离、红色或橙色博氏线和甲下角化过度。如本病例所报道的甲下出血(SH)与多西他赛的累积剂量有关,不应归因于其他全身性疾病。临床医生应认识到这种并发症,避免过度治疗或检查,并告知患者紫杉烷类药物继发指甲变化的可能性。
