Carotid Artery Resection and Reconstruction due to Benign and Malignant Head and Neck Tumors.

OBJECTIVE: Carotid resection for head and neck cancer is rare, and serious complications may arise since such cancer is frequently detected in advanced stages. The objective is to describe nine cases of carotid artery resection and reconstruction due to tumor invasion. METHODS: The clinical records of nine patients who underwent carotid resection and reconstruction at our hospital were retrospectively reviewed. Carotid body tumors were evaluated with the aid of a vascular team in case carotid resection was necessary at the time of surgery. CT angiography to determine the status of the circle of Willis was performed in all patients who might undergo carotid resection and reconstruction in case of failure to restore cerebral blood flow and thus reduce possible sequelae due to ligation. RESULTS: Of nine patients, 6 had carotid body tumors, 1 had a thyroid tumor of conglomerate lymph nodes, 1 had a larynx tumor of conglomerate lymph nodes, and 1 had a myofibroblastic tumor. There were no intraoperative cerebrovascular accidents. One patient (11.1%) had a cerebrovascular accident secondary to carotid hematoma in the intermediate postoperative period that required vascular graft removal. One patient (11.1%) died seven days after surgery following an ischemic cerebrovascular accident. Eight patients remain asymptomatic, and 1 patient with recurrence and metastasis. CONCLUSIONS: Carotid resection remains a controversial issue in the treatment of advanced head and neck cancer. However, carotid resection and reconstruction are required for disease control, and complications such as thrombosis or vascular accidents may arise. Fortunately, this is a rare condition. We recommend carotid reconstruction for all patients in whom resection is required for tumor control. Ligation should be a last resort, as seen in the management of one of our patients.

Transcervical Approach in a Thrice Recurrent Parapharyngeal Space Tumor.

Parapharyngeal space tumors are rare and account for 0.5% of all head and neck tumors. Most of them are benign (95%), of which pleomorphic adenomas of the salivary gland are the most common. Due to their anatomical location, gaining surgical access while avoiding postoperative morbidity is the main limitation. We present the case of a 35-year-old male with a history of three transcervical resections of benign pleomorphic adenomas in the parapharyngeal space within the deep lobe of the parotid gland. The patient has been followed for more than ten years and maintains an adequate quality of life.

Conservative Treatment with CO2 Laser for oral Mucosal Melanoma: A case Report.

Mucosal melanoma of the head and neck is a rare and aggressive malignancy with poor prognosis even after extensive resection. A 76-year-old male with melanoma of the hard palate underwent CO2 laser resection as a conservative treatment to preserve his quality of life. Six months after lumpectomy the patient was asymptomatic and had no tumor activity. Recurrence is the rule. Local or regional relapse occurs at any time and patients eventually die from distant metastasis.

Acrometastasis: The Tip of the Iceberg of Metastatic Disease from Thyroid Cancer. Two Cases Report.

Acrometastasis, especially in the hands and fingers, is a rare clinical condition resulting from primary cancers such as lung, breast, kidney, and, rarely, thyroid cancer. Acrometastasis tends to be the tip of the iceberg in patients with extensive systemic disease, which could be regional, pulmonary, skeletal, neurological, or all of them combined. Even though these tumors are clearly visible and symptomatic, the diagnosis is usually misleading because such distal metastatic disease is not thought of at first. In general, systemic treatments should be given to any patient presenting digital acrometastasis. We describe two cases of papillary thyroid carcinoma and digital acrometastasis as a sign of advanced disease.

Desmoid Tumor of the Posterior Neck: A Case Report.

Desmoid tumors are rare. They account for roughly 0.03% of all neoplasms and less than 3% of all soft tissue tumors. They are locally aggressive tumors with no known metastatic potential or dedifferentiation. A 29-year-old woman with no family history of neoplasms presented with a mass in the cervical region and moderate pain that had developed a year before. The patient underwent marginal resection of the bilateral posterior and lateral compartments of the neck. The histopathological report confirmed the diagnosis of desmoid tumor with nuclear positivity for beta-catenin. The patient received radiotherapy but did not show a favorable response; she has stable disease and takes colchicine at one-year follow-up.
