Liposarcomas of the head and neck: a review of the literature and addition of four cases.

Liposarcomas of the head and neck are rare. There have been 25 previously reported patients in the literature. Four patients with head and neck liposarcomas, recently treated by the Head and Neck Surgery Service, Walter Reed Army Medical Center, are presented. Less than half of reported patients were noted to be living without evidence of disease. Prognosis generally corresponds to the cell type of the tumor. Intraoral, cheek and orbital tumors seem to have a worse prognosis compared to neck tumors. Wide local excision remains the treatment of choice. Advances in surgical techniques have allowed adequate therapy for most head and neck liposarcomas. Advanced lesions should be managed by conservative surgery and radical radiation therapy.

Simultaneous recurrent multiple chemodectomas.

We report a case of concomitant, recurrent carotid body tumor and recurrent bilateral glomus jugulare tumors, with extensive intrajugular-venous extension. The patient's family history confirms the previously reported familial occurrence of chemodectomas. The value of preoperative angiographich evaluation is emphasized in establishing a diagnosis and formulating a therapeutic approach. Recurrence of chemodectomas after appropriate therapy, although unusual, was present in all three previously treated sites in this patient.

The surgical management of recurrent parotitis.

Twenty-eight parotidectomies were carried out upon 26 patients with chronic parotitis. The lesion considered is chronic inflammation of the parotid gland associated with such intraglandular defects as sialadenitis secondary to ductal obstruction by calculi, cellular debris, stenosis or infiltrating lesions, that is, Mikulicz's or Sjögren's syndromes and sialoangiectasis, either primary or secondary to obstruction of the duct. Seventeen near total parotidectomies were done without significant complications or a recurrence of symptoms. Eleven superficial parotidectomies were performed in which symptoms recurred on the 12th postoperative day in one patient. No permanent weakness of the facial nerve occurred in any of the 28 parotidectomies. Based upon this experience, near total parotidectomy with removal of the parotid duct can be performed safely and should be the procedure of choice in patients with chronic, relapsing parotid sialadenitis.

Squamous cell carcinoma of the buccal mucosa associated with chronic oral polyvinyl chloride exposure: report of a case.

The following case report describes a 22-year-old healthy man, non-smoker, non-drinker, who developed a squamous cell carcinoma of the buccal mucosa. The appearance of this unusual tumor in an unexpected clinical setting was unexplained until it was discovered that the patient had a lifetime habit of chewing plastic materials containing polyvinyl chloride (PVC). The extent and chronicity of his intense oral exposure to PVC is believed to be related to his subsequent development of an oral neoplasm. Attention is again focused on PVC as an important environmental toxin and carcinogenic agent. Clarification of the content of PVC in consumer products is urged. Physicians must remain aware of possible environmental carcinogens in patients presenting with unexpected or rare malignancies. Detection of such exposure may well prevent subsequent development of additional unexplained neoplasms.
