The treatment of PTM is a clinical challenge. We herein report on a patient with PTM who achieved complete remission by multipoint subcutaneous injections of a long-acting glucocorticoid and topical glucocorticoid ointment application for a self-controlled study. A 53-year-old male presented with a history of GD for 3.5 years and a history of PTM for 1.5 years. Physical examination revealed slight exophthalmos, a diffusely enlarged thyroid gland, and PTM of both lower extremities. One milliliter of triamcinolone acetonide(40 mg) was mixed well with 9 mL of 2% lidocaine in a 10 mL syringe. Multipoint intralesional injections into the skin lesions of the right lower extremity were conducted with 0.5 mL of the premixed solution. A halometasone ointment was used once daily for PTM of the left lower extremity until the PTM had remitted completely. The patient's PTM achieved complete remission in both legs afteran approximately 5-mo period of therpy that included triamcinolone injections once a week for 8 wk and then once a month for 2 mo for the right lower extremity and halometasone ointment application once daily for8 wk and then once 3-5 d for 2 mo for the left lower extremity. The total dosage of triamcinolone acetonide for the right leg was 200 mg. Our experience with this patient suggests that multipoint subcutaneous injections of a long-acting glucocorticoid and topical glucocorticoid ointment application are safe, effective,and convenient treatments. However, the topical application of a glucocorticoid ointment is a more convenient treatment for patients with PTM. 展开更多
