title: Results of initial lymph node biopsy in homosexual men with generalized lymphadenopathy.
abstract: Persistent, generalized lymphadenopathy (PGL) is considered part of the acquired immunodeficiency syndrome (AIDS)-related complex. The clinical course is usually benign, although some patients may evolve to AIDS. Characteristic features on lymph node biopsy have been described. Recently, large series of PGL have been reported in which many study patients have not undergone initial diagnostic biopsy. The value of such biopsy has been questioned. We report the clinical, pathologic, and laboratory findings in six homosexual men initially considered as potential candidates for study of the natural history of PGL. They were excluded by initial lymph node biopsy, which revealed small-cleaved lymphoma in two, focal Kaposi's sarcoma in two, disseminated mycobacterium tuberculosis in one, and histoplasma encapsulatum in one. The clinical and laboratory data from these six patients were compared with those from 34 patients with biopsy-proven PGL; no statistically significant difference in any prebiopsy clinical parameter was found. We conclude that initial lymph node biopsy may reveal changes other than reactive hyperplasia in homosexual men with generalized lymphadenopathy.
