Abstract PDF

It is difficult to distinguish nodular fasciitis (NF) from other neoplasm of the parotid gland, especially pleomorphic adenoma (PA) by fine needle aspiration cytology. A 39-year-old female noticed a mass in the parotid region. The aspirate material showed cohesive parts composed of the cells that had oval or spindle-shaped nuclei and relatively abundant cytoplasm and some cells with plasmacytoid features. The background substance was fibromyxoid. PA was diagnosed based on the cytologic findings. Subsequently, parotidectomy was performed and NF was diagnosed based on histologic and immunohistochemical findings. NF in the parotid region is rare and may be misdiagnosed as other benign or malignant tumors of the parotid gland. The clinical history of rapid growth and the presence of mitoses and inflammatory cells help to distinguish NF from PA. In addition, immunohistochemical stains for smooth muscle actin and CD68 are useful to confirm the diagnosis of NF.

Abstract PDF: The authors report 16 cases of mediastinal fine-needle aspiration cytology from Jan. 1985 to Mar. 1988 at the Seoul National University Hospital. Among them, diagnostic materal were obtained in fifteen cases, establishing the diagnosis of 7 thymomas, 2 germinomas, 2 neurogenic tumosr, 1 lymphoma, and 3 meastatic carcinomas. The 9 cytologic diagnoses could be confirmed by histologic examination in 8 patients and by another cytologic method in one patient, allowing concordance rate of 77%.

Abstract PDF: A statistical analysis of the diagnostic value for 244 aspiration biopsy cytology(ABC) among a total 1,043 cases from various sites was performed. ABC, using diagnostic terminology similar to that of a surgical pathology reports, was compared to the final tissue diagnosis. For the entire series, a sensitivity of 91.8%, a specificity of 99.3%, a positive predictive value of 98.9%, a negative predictive value of 94.8%, and an efficacy of the test of 96.3% were shown. There were 8 false negative and 1 false positive diagnosis. The diagnostic accuracy was 89.8%. Those results indicate that the ABC is a considerably highly accurate procedure that should be routinely employed.

Abstract PDF: It is well known that fine needle aspiration biopsy(FNAB) is very useful and has a high accuracy rate in the diagnosis of renal neoplasms. Although there is some indecision to perform the FNAB for a rare possibility of tumor seeding along the biopsy needle tract, it tends to be used increasingly. As in the cytologic diagnosis of metastatic lesion through out the body, renal cell carcinoma should nearly always be considered in the differential diagnosis, the precise understainding of cytologic features of renal cell carcinoma with various cell types and architectural patterns is necessarily required. In this report, we present three cases of primary renal cell tumors, two of renal cell carcinomas and one of oncocytoma, preponderantly emphasizing the cytologic differential points in the FNAB specimen.

Abstract PDF: A sex cord tumor with annnular tubules is a relatively rare ovarian neoplasm. The cytologic findings from a fine needle aspiration biopsy of neck metastasis of a sex cord tumor with annnular tubules are described. The origin of the neck metastasis was the right ovary, and the tumor was diagnosed six years ago. The cytologic findings were characterized by tumor cells arranged in solid or follicular patterns. The tumor cells formed rosette-like or complex tubular structures with central rounded or coalesced hyaline materials. It was difficult to distinguish this tumor cytologically from granulosa cell tumor, thyroid follicular neoplasm, Sertoli-Leydig cell tumor, and Brenner tumor, but complex tubular structures were helpful in discriminating between these tumors.

Abstract PDF: Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft tissue tumor. There have been only a few prior fine-needle aspiration (FNA) cytological reports. Recognition of this tumor is important because of its potential for metastasis despite its indolent nature and its deceptively bland cytologic appearance. A 60-year-old male presented with a slowly growing mass in the left calf detected 10 years ago. The patient underwent surgical excision. FNA cytology was performed directly on the mass. The smears showed low cellularity composed of hypercellular tissue fragments, hypocellular loose aggregates, and stripped nuclei. The cytoplasm was seen as either collagenous material or very thin fibrillary collagen strands. Tumor cells had spindle, ovoid, or irregular nuclei, fine chromatin, and small nucleoli. Focally slight degree of nuclear pleomorphism is noted. There were no mitotic figures. Blood vessels were frequently seen. Immunocytochemically, tumor cells were negative for S-100 protein, desmin, smooth muscle actin, and CD34. The diagnosis of LGFMS is rarely possible by cytology alone; however, LGFMS should be included in the differential diagnosis of spindle-cell tumors consisting of hypercellular and hypocellular components with some capillary-sized vessels arising in the deep soft tissue of the lower extremities, particularly the thigh. The immunocytochemical findings are of help in the differential diagnosis.
