A 47-year-old woman complained of a painless swelling on the right lateral neck, which grew slowly for 5 months after discovery. Weak pain radiating out the arm and the hand was experienced by palpation.
Examination revealed an about 5×7cm, firm, fixed mass with tumor vessels in the right supraclavicular region. There was also a palpable nodular lesion in the right lobe of the thyroid. Calcification on a plain film and a cold nodule in thyroid scintigram were evident.
A right hemithyroidectomy with radical neck dissection was performed for malignant struma and cervical metastasis. The nodular lesion in the thyroid proved to be a follicular adenoma, and the lateral neck tumor was a neurilemmoma of Antoni-A type, arising in the brachial plexus.
A 67-year-old man underwent incomplete resection of the right infraauricular tumor in a certain hospital, and ulcerative change and sialorrhea then appeared.
After twice sessions of cryosurgery, the tumor became a painful mass and he was introduced to our clinic.
A fixed mass of about 5×7cm was noted in the right infraauricular and submandibular region and there was an ulcerative lesion of about 3cm in diameter, bulging into the lumen of the pharynx. Examination revealed calcification on a plain film and abnormal accumulation of 67Ga citrate in scintigram.
Suspected of being a malignant tumor of the parotid gland, the patient underwent a total parotidectomy with facial nerve preservation, radical neck dissection and partial pharyngectomy. The pathology revealed a ganglioneuroma.
After 2 months, a firm, fixed, slightly tender tumor, about the size of the tip of the thumb could be palpated in the left supraclavicular region. Surgery revealed a neurilemmoma of Antoni-A type beneath the anterior scalenus muscle.
