Transcervical excision of thymoma and video-assisted thoracoscopic extended thymectomy (VATET) for ectopic cervical thymoma with myasthenia gravis: report of a case.
Myasthenia gravis is the most common disease associated with thymoma, but it is rarely accompanied by ectopic thymoma. We describe a 47-year-old woman who presented with an ectopic cervical thymoma with myasthenia gravis. She was admitted to our neurology department with ptosis, diplopia, and mandibular muscle fatigue, and was diagnosed with myasthenia gravis. The mass was located posterior to the right lobe of thyroid gland on computed tomography and was diagnosed as ectopic thymoma on fine-needle aspiration biopsy examination. Transcervical excision of thymoma and VATET were performed. The patient has been free of neurological symptoms and has displayed no evidence of recurrent thymoma for 2 years.
