Abstract
Nail toxicity is an uncommon cutaneous adverse effect of imatinib mesylate. Here, we have described a 45-year-old female, a diagnosed case of Philadelphia positive chronic myeloid leukemia, who was on imatinib mesylate for the past 3 months and developed bluish discoloration of the nails. This discoloration was related to the drug imatinib mesylate because the patient was only on imatinib and thyroxine medication. No any other skin-related diseases was present, which can lead to her nail changes.
