Lymphoglandular bodies in fine-needle aspiration cytology smears.
Lymphoglandular bodies (hyaline bodies or lymphoid globules), when found in cytology smears from fine-needle aspirates, have long been accepted as being diagnostic of lymphoid tissue. To investigate the validity of this association as it relates to malignant tumors, we examined cytologic smears from 132 fine-needle aspirates of malignant neoplasms. Three experienced observers independently scored Diff-Quik-stained smears as to cellularity and number and size of lymphoglandular bodies. Discrepancies were resolved by consensus. Results of the fine-needle aspiration biopsies revealed 6 of 104 nonlymphoid malignancies with easily identifiable lymphoglandular bodies (defined as > 2 lymphoglandular bodies per high-power field) and 3 with numerous lymphoglandular bodies (> 10 per high-power field). These tumors consisted of two cases of small-cell carcinoma, four non-small-cell carcinomas, one ganglioneuroblastoma, one melanoma, and one seminoma. The tumors had few, if any, lymphocytes. Of the 28 lymphomas, 5 had easily identifiable lymphoglandular bodies and 19 had numerous lymphoglandular bodies. Although lymphoglandular bodies in the background of cytologic smears taken from malignant tumors are useful in alerting the pathologist to the possibility of lymphoma, there are exceptions.
