ABSTRACT
Fibrolipomas are benign lesions conformed by fat and connective tissue, classified as histologic variants of lipomas. They are rarely located in the head and neck and represent less than 0.6% of the benign tumors of the larynx and hypopharynx. Their clinical presentation depends on its location and size. We present the case of a 51-year-old male patient who reported progressive dyspnea, dysphagia and obstructive sleep symptoms with a duration of 3 months, without apparent cause. A pharyngolaryngeal fiberoptic endoscopy showed a smooth, rounded mass in the posterior wall of the hypopharynx, partially obstructing the laryngeal vestibule, creating a valve effect. Complete trans-cervical resection of the lesion was performed after the airway was secured by means of a tracheotomy. The final histopathology report was fibrolipoma. He is currently asymptomatic and without evidence of relapse one year after the procedure.
ABSTRACT
Angiosarcomas are malignant neoplasias of rapid growth that develop from endothelial cells. They represent 2% of all sarcomas and only 1-4% are located in the aerodigestive tract. Since 1977, only 16 cases have been reported.We present a 33-year-old male with spontaneous epistaxis that was refractory to cauterization. During physical examination, a smooth purplish tumor of 1.5 cm x 1.5 cm was identified. A CT scan showed a nonenhanced tumor in the left nostril on the uncinate process. A biopsy revealed an intermediate-grade angiosarcoma. Surgical removal followed by radiation therapy was performed with good result. Aerodigestive angiosarcomas have a better prognosis than angiosarcomas of other locations due to better cell differentiation and the presence of early symptoms. Recurrence can occur because of tumor tissue left during resection. Our patient continues tumor free after three years.
