Cytology and immunocytology of infectious mononucleosis in fine needle aspirates of lymph nodes.

Two cases of infectious mononucleosis with atypical clinical presentations were initially diagnosed by fine needle aspiration (FNA) of lymph nodes and subsequently confirmed by serologic studies. The cytologic features that allowed recognition included a high percentage of cells with relatively abundant cytoplasm that stained pale to deep blue using a Giemsa-type stain. Many of the cells had plasmacytoid features. The cells ranged in size from small lymphocytes to large immunoblastic forms. Other features included mitotic figures and occasional binucleated forms. Immunologic studies showed a mixture of B and T cells, with many of the cells having a cytotoxic/suppressor phenotype. The features seem to be relatively characteristic and distinct from those of malignant processes that could be aspirated in lymph nodes. Recognition of infectious mononucleosis by FNA in these cases allowed for confirmation by serologic studies, thereby avoiding the need for an excisional biopsy. These cases show that FNA of lymph nodes may shed light on the nature of the process underlying the lymphadenopathy in selected cases of clinically atypical infectious mononucleosis.

Fine needle aspiration cytology of neoplasms metastatic to the breast.

The fine needle aspiration (FNA) cytologic findings in 18 cases of metastatic neoplasms of the breast are reported. The cases were encountered in a combined series of 2,529 FNA breast biopsies, of which 666 were malignant; the metastatic neoplasms of the breast thus constituted 2.7% of all the malignant breast tumors. The series consists of 15 women and 3 men, with a mean age of 48 years (range of 11 to 73 years). Sixteen biopsies confirmed metastatic malignancy in patients with known extramammary primaries; the prebiopsy clinical diagnoses in six of the patients were benign breast lesions. In eight patients, the clinical differential diagnosis was either a benign or malignant primary breast lesion versus a metastatic malignancy. In two additional patients, the FNA biopsy identified metastatic neoplasms from unsuspected extramammary primaries. The metastatic neoplasms included three small-cell carcinomas of the lung, one squamous-cell carcinoma of the lung, two malignant melanomas, three ovarian malignancies, including a dysgerminoma, and one each of carcinoma of the fallopian tube, endometrial carcinoma, transitional-cell carcinoma of the urinary bladder, prostatic carcinoma, acute granulocytic leukemia, lymphoma, mycosis fungoides, hepatoma and neuroblastoma of the retroperitoneum. Recognition of unusual cytologic patterns raised the suspicion of, or confirmed the diagnosis of, malignancy in all cases, with no false-negative diagnoses. None of the cases were cytologically interpreted as a primary breast malignancy. Ancillary studies performed on the FNA material, including immunocytochemistry, contributed to a definitive diagnosis in three cases. FNA diagnosis of metastatic malignancy of the breast is essential in order to avoid unnecessary mastectomy and to ensure appropriate chemotherapy and/or irradiation treatment.

Fine needle aspiration cytology of benign lymph node hyperplasias. Diagnostic significance of lymphohistiocytic aggregates.

The fine needle aspiration cytomorphology and the number of lymphohistiocytic aggregates were correlated with five categories of benign lymph node histologies. Of 187 patients who had benign lymph node aspiration diagnoses made from 1975 to 1982 at the Medical College of Virginia, 26 had a subsequent lymph node biopsy. Excluded from the study were four cases with the biopsy site different from the aspiration site, three cases with evidence of metastatic carcinoma and one case of fistula at the site of biopsy. Of the remaining 18 cases, 13 (72%) had lymphohistiocytic aggregates on the aspiration slides. The mean number of lymphohistiocytic aggregates on the aspiration slides was greater in cases with histologic evidence of follicular hyperplasia (6.1) than in those with some other predominating benign histology (1.6).

Fine needle aspiration biopsy in the diagnosis of sarcoid of the head and neck.

The use of fine needle aspiration biopsy to confirm the clinical diagnosis of six cases of sarcoidosis with palpable disease in the head and neck area is reported. The procedure was simple and inexpensive, and the interpretation of the smears and identification of typical sarcoid granulomas was easy.

Fine needle aspiration biopsy of the thyroid. Differential diagnosis by videoplan image analysis.

Fine needle aspiration biopsy of cold thyroid nodules has become increasingly popular in determining neoplastic versus nonneoplastic conditions. The differential diagnosis between follicular adenoma and low-grade follicular carcinoma has not been consistently attainable, however; adenomatous goiter also may present problems in diagnosis, while papillary carcinoma seldom proves to be a difficult diagnosis. Image analysis, utilizing the Videoplan image analysis system, was performed on fine needle aspiration biopsy smears from these four types of nodules. The nuclear area, maximum diameter, minimal diameter and approximation to a circle were determined for 25 randomly selected cells with intact nuclei in each smear. These values were calculated with a range and standard deviation and were graphed for each parameter by case category. Cytoplasmic measurements could not be performed due to the absence of definite cytoplasmic boundaries. There was no significant difference in mean nuclear area between follicular adenoma, follicular carcinoma and adenomatous goiter. Papillary carcinoma was the only lesion to show any difference with this single parameter. The mean of maximum and minimum diameter and approximation to a circle were similar for all the types of thyroid masses examined in this study. The Videoplan image analysis system provided an efficient and accurate means of obtaining the nuclear measurements and calculating the statistics. These data illustrate that a differential diagnosis between follicular adenoma, follicular carcinoma and adenomatous goiter, while difficult by light microscopy, is not aided by image analysis of individual cell nuclei.

Spindle and giant cell carcinoma of the thyroid: cytologic diagnosis by fine needle aspiration.

Eight patients with spindle and giant cell carcinoma of the thyroid were seen between 1973 and 1977 at the Medical College of Virginia, representing 12% of all neoplasms of the thyroid in that period. The mean age at detection was 69.2 years. The mean survival was 5.3 months. Fine needle aspiration was performed in six of these eight patients In all six patients the diagnosis could be made cytologically. The cytologic characteristics of this lesion are presented, and the differential diagnosis is discussed.
