Carotid body tumors (CBT) are a rare entity that should be considered in evaluating every lateral neck mass. The objective of the study was to compare demographic data, complications and evolution of patients treated at our institution. A retrospective study was made of 66 patients with 69 CBT that were treated at our institution between 1982 and 2002. We reviewed the demographic characteristics, clinical features, surgical approach and complications. Women significantly predominated (96.9%) with a female:mate ratio of 31.2:1. Ages ranged from 18 to 94 (mean = 50.2). Fifty-four per cent of the patients lived at attitudes higher than 2200 m above sea level. The most common chief complaint was a painless neck mass (78.7%). No patient had any malignant tumors or a familial history of CBT. Both sides were similarly affected. There were four tumors grouped in Shamblin's class I, 24 in class II, and 35 in class III. Six tumors were of undetermined Shamblin's class as inferred from their medical records. Fifty-three patients received treatment: 46 (86.8%), surgery; 6 (11.3%), radiotherapy; 1 (1.9%), radiotherapy following surgery. Three patients (6.3%) underwent vascular reconstruction. In 23 (49%) patients neurological deficit was observed after surgery. Minor complications occurred in five (10.6%) patients. Median follow-up was 38 months, one patient died from a cause not related to the CBT, and the rest remain disease-free and asymptomatic. We found an overwhelming predominance of women, which opens the possibility that we are dealing with a different disease in female Latin populations. Most of the tumors were of Shamblin's class III CBT. Early surgical management is recommended to avoid neurological deficit due to a Shamblin's class III tumor. (C) 2004 Elsevier Ltd.
