In patient's history there total for multinodular goiter, performed 9 years previously at which well-encapsulated subcapsular adenoma left lobe also incidentally discovered. At 12 months follow-up, patient showed well wounds healed.Subcutaneous colonization seeding occurrence reported in literature both benign malignant pathologies; among ones, follicular carcinoma cells most frequent.
