A marked increase has recently been noted in the incidence of lymphoma in patients with AIDS. These lymphomas are generally high-grade, of B-cell origin, and often involve extranodal sites. Reported here are twenty patients with AIDS in whom symptoms and physical findings developed related to the head and neck region as a result of lymphoma. The tumor was observed in a variety of sites, including the nasopharynx, orbit, submandibular triangle, anterior and posterior cervical triangles, supraclavicular fossa, and the hypopharynx. Sixteen tumors were large cell nonHodgkin's B-cell lymphomas, three were small cell nonHodgkin's B-cell lymphomas, and one was Hodgkin's disease, mixed cellularity. All were treated with combination chemotherapy. A high degree of suspicion for lymphoma is required in treating any patient with AIDS who has a rapidly enlarging mass in the head and neck. If needle aspiration is nondiagnostic, excisional biopsy should be performed after a complete head and neck evaluation. Although the development of lymphoma associated with AIDS portends a grave prognosis, prompt diagnosis will allow an improved chance of remission of the lymphoma.

Concern over the rising cost of health care has created a trend toward outpatient surgery. Because adenotonsillec‐tomy is such a frequently performed procedure, there is pressure on many otolaryngologists to do this operation on an ambulatory basis. A prospective study was undertaken to evaluate the incidence and severity of postoperative hemorrhage, protracted emesis, and fever at specified times within the first 24 hours after surgery.Over a 1‐year period, 1000 tonsillectomy and/or adenoidectomy patients were studied. There was a 2.1% incidence of serious complications within the first 6 postoperative hours. The incidence of serious hemorrhage, fever, and protracted emesis was 0.7% each. The incidence of significant complications between the 6th and 24th postoperative hours was 1.7%. Hemorrhage occurred in 0.4% of the patients, fever in 0.7%, and protracted emesis in 0.6%. The total incidence of hemorrhage during this time period was 1.1%. There were no deaths.The greatest percentage of complications occurred within the first 6 postoperative hours. Based on this study, outpatient tonsil and adenoid surgery should be followed by at least 6 hours of postoperative observation before discharge. The choice to perform ambulatory tonsil and adenoid surgery depends on the professional judgment of the operating physician based on this and other recent studies, the sophistication of the physician's ambulatory surgery center, and the medical and social background of the patient.
