| Resumo: | Introduction: Mucocutaneous hyperpigmentation is a dermatological condition that may be related to chemotherapy treatments, such as therapies using hydroxyurea (HU). HU is a cytostatic drug widely used in myeloproliferative diseases and is the main line of treatment for essential thrombocythemia (ET). The present study aims to report a rare case of mucocutaneous hyperpigmentation in a patient with ET. Case report: Male patient, 68 years old, 89 kg, diagnosed with ET using HU 2 g/day. After three months of therapy, he presented hyperpigmented brownish-colored lesions on the hands and oral cavity (tongue). In a decision shared with the assistant physician, the patient chose to continue using the drug. After six years of follow-up, the lesions remain stable. Conclusion: Mucocutaneous hyperpigmentation associated with HU therapy is a benign event secondary to the use of the drug and does not require discontinuation of use, however, its withdrawal or dose reduction usually leads to the reduction or disappearance of the lesions. |
