Session: SUN 459-496-Thyroid Neoplasia & Case Reports
Poster Board SUN-486
Background: Tyrosine kinase inhibitors (TKI’S)can be considered as the standard option of treatment in patients with metastatic radioiodine refractory differentiated thyroid cancers 1. The cutaneous manifestations of Sorafenib include rash, desquamation, hand foot skin reactions, pruritus, alopecia and erythema2. We report the first case of depigmentation related to sorafenib therapy.
Case presentation: We report the case of a middle aged gentleman with metastatic papillary carcinoma of thyroid diagnosed in 2005. He was managed with total thyroidectomy, radioactive iodine and TSH suppressive therapy. Despite receiving radioactive iodine 530 mci cumulative dose, patient had persistant disease with lung metastasis. Therefore a TKI, Sorafenib, was started. He developed depigmentation of the skin more prominent on face 6 weeks after starting Sorafenib treatment.He also developed diarrhea, desquamation of hands and feet, hair loss over scalp, eye brows and moustache. Sorafenib treatment was discontinued. His diarrhea stopped in one week and after 4 weeks his skin became normalized whereas he regained his hairs in six weeks.
Conclusion: This is the first case reporting the Depigmentation as rare unknown side effect of Sorafenib therapy.
