Summary
Antineoplastic agents can cause nail changes like melanonychia and leukonychia. This study highlights less common leukonychia cases linked to chemotherapy, expanding understanding of drug-induced nail dyschromia.
Area of Science:
- Oncology
- Dermatology
- Pharmacology
Background:
- Nail dyschromia, specifically chromonychia, is a known side effect of antineoplastic agents.
- Melanonychia (nail pigmentation) is the most frequent type, often appearing as bands or diffuse pigmentation, commonly associated with adriamycin, cyclophosphamide, or polychemotherapy.
- Leukonychia (white discoloration of nails) is a less frequently reported nail alteration due to these agents.
Observation:
- This report details two cases of leukonychia observed in patients undergoing treatment with antineoplastic agents.
- The occurrence of leukonychia, while less common than melanonychia, represents a notable adverse effect of chemotherapy.
- These cases underscore the spectrum of nail color changes that can arise from cytostatic drug therapies.
Findings:
- Confirmed leukonychia as a potential, albeit less frequent, manifestation of drug-induced chromonychia.
- Contributes to the clinical understanding of nail side effects associated with various antineoplastic treatments.
- Highlights the importance of monitoring for diverse nail color changes during chemotherapy.
Implications:
- Broadens the differential diagnosis for nail dyschromia in patients receiving chemotherapy.
- Informs clinicians about the possibility of leukonychia as a side effect, prompting careful patient observation.
- Suggests further research into the specific mechanisms and incidence of leukonychia induced by different antineoplastic agents.
