[Pseudoadenopathies].

The results of a study concerned with the etiology of some lymph node enlargement in 511 cases aged between 16-80 years, admitted to the III-rd Medical Clinic of Iaşi during the last 7 years are presented. A thorough investigation, by histopathological, cytological, haematological, biochemical, immunological, lymphographic, echographic, radiological examinations, has been done. In 44 cases, the results of the above mentioned investigations indicated that there was no lymph node enlargement, but some other masses sharing the same sites with the lymph nodes, which generated the misdiagnosis in outpatient practice. It is important to note that in 28 cases (63% of the 44 cases) the pseudoadenopathies were localized in the cervical area. The pseudoadenopathies, which are the clinical expression of some tumoral diseases, could be classified as follows: a.--single peripheral; b.--generalized, peripheral; c.--deep. The symptoms which permit the differential diagnosis between the true and pseudoadenopathies are analysed.
