To determine the incidence of metastatic cancer to the neck from asymptomatic primary tumors in thorax, abdomen or pelvis.
Two years term (January 1992 to December 1993) retrospective study.
Presentation of 57 patients with a neck mass which through puntion-aspiration (FNB), cervicotomy and biopsy confirmed any type of carcinoma.
In 39 cases (68.42%) a primary tumor either in the pharynx or mouth were affirmative of growth; in other 10 (17.54%) the site of the primary remainded unknown; and 8 cases (14.04%) the primary tumor even asymptomatic could be localized inside the thorax or abdomen (3 pulmonary, 2 kidney, 1 stomach, 1 prostate and 1 esophagus). In other 2 occurrences, a cervicofacial association existed (1 case a synchronic growth of the hypopharynx-prostate, the other one cavum pharyngis and lung).
Cases diagnosed as asymptomatic thoracic or abdominal tumors are commented and its bibliography reviewed. The same as diagnostic strategy in hidden primaries aiming to the probability of ascertain the sitting in each diagnostic stage.
确定胸部、腹部或骨盆无症状原发性肿瘤转移至颈部的癌症发生率。
为期两年（1992年1月至1993年12月）的回顾性研究。
57例有颈部肿块的患者，经穿刺抽吸（FNB）、颈部切开术及活检确诊为任何类型的癌。
39例（68.42%）患者的原发肿瘤位于咽或口腔，已确定有肿瘤生长；另外10例（17.54%）原发部位不明；8例（14.04%）原发性肿瘤即使无症状也可定位在胸部或腹部（3例肺部、2例肾脏、1例胃部、1例前列腺和1例食管）。另外2例存在颈部与面部的关联（1例为下咽-前列腺同步生长，另1例为咽腔和肺部）。
对诊断为无症状胸腹部肿瘤的病例进行了评论，并对其文献进行了综述。同样，针对隐匿性原发肿瘤的诊断策略旨在确定每个诊断阶段的病变部位。
