Fine needle aspiration cytology of "cold" nodules of the thyroid has proved to be of great value in their preoperative diagnosis. Most types of thyroid tumors are readily recognizable from characteristic cellular patterns in the smears of needle aspirates. But follicular neoplasms present some problems because the cytomorphology of the adenomas frequently is same as in carcinoma. For differentiation of benign from malignant follicular neoplasms of the thyroid we tested the usefulness of two objective parameters - nuclear area and perimeter - by morphometry. This study was made on fine needle aspirates from 30 cases with cytologic diagnosis of follicular neoplasm of thyroid. The histologic classification was follicular adenoma in 22 cases and follicular carcinoma in 8 cases. As a reference group we used seven caes with nodular hyperplasia. The smears of aspirates were stained by Papanicolaou method. On each slide 200 randomly selected cells with intact nuclei were measured. The mean value of nuclear area are $25.32{\pm}5.50{\mu}m^2,\;34.08{\pm}7.50{\mu}m^2\;and\;39.97{\pm}6.63{\mu}m^2$ in nodular hyperplasia, follicular adenoma, and follicular carcinoma, respectively. The mean value of perimeter are $19.48{\pm}2.26{\mu}m,\;22.95{\pm}2.65{\mu}m\;and\;24.78{\pm}2.23{\mu}m$ in nodular hyperplasia, follicular adenoma and follicular carcinoma, respectively. The mean nuclear areas and perimeters of cells from follicular adenoma were significantly larger than those from nodular hyperplasia (p<0.05). The mean nuclear areas and perimeters of cells from follicular carcinoma were larger than those from follicular adenoma but the differences are not significant statistically(p>0.05). Therefore, morphometric assessment alone is inadequate to predict malignancy in thyroid aspirates.

Metaplastic carcinoma of the breast is a morphologically heterogenous group of neoplasms characterized by ductal adenocarcinoma with extensive squamous differentiation, a spindle-cell pattern of growth, and/or heterologous mesenchymal elements. We experienced a case of metaplastic carcinoma diagnosed by fine needle aspiration(FNA) and confirmed by radical mastectomy in a 46 year-old woman. The FNA cytologic findings included atypical squamous cells with kertinization tying singly and in clusters in a necrotic background. In addition, scattered spindle cells with pleomorphic large nuclei and prominent nucleoli were present in a hemorrhagic and necrotic background. The histopathologic findings showed moderately differentiated squamous cell carcinoma and highly pleomorphic sarcoma with chondroid component. The immunohistochemical stain revealed focal positive reaction for cytokeratin as well as diffuse reactivity for vimentin in the sarcomatous area.

Patients with rheumatoid arthritis of any degree of severity or duration may develop necrotizing granulomatous pleuritis, a morphologic replica of the inflammatory reaction characteristic of rheumatoid synovitis and rheumatoid nodules. The principal feature is the background composed of granular, amorphous, particulate material or debris of various hues. The material is sometimes eosinophilic sometimes more cyanophilic, or even green in the Papanicolaou stain. Within this background are elongated, fibroblast-like epithelioid cells, numerous multinucleated giant cells and degenerating leukocytes. The combination of the debris, spindle epithelioid ceils, and multinucleated giant cells in fluid is pathognomonic for rheumatoid pleuritis. We experienced a hcase of rheumatoid pleuritis showing these characteristic cytologic findings. The patient was a 63 year-old man with positive rheumatoid factor. The pleual fluid specimen revealed elongated epithelioid cells and multinucleated giant cells on a background of amorphous granular material.
