摘要:

AbstractThe cytologic and histologic findings of seven cases presenting clinically as salivary gland swellings are described. These included two cases of pilomatrixoma of skin in the parotid region, two cases of neurilemmoma in the submandibular area, a case of Kimura's disease in the peri‐mandibular gland lymphoid tissue, a case of Castleman's disease in intraparotid lymph node, and a case of branchial cleft cyst in the parotid region. It is important to recognize lesions that masquerade as salivary gland tumors so that misdiagnosis and overdiagnosis on smears can be avoided and the patients can be treated appropriately. © 1992 Wiley‐Liss,

摘要:

AbstractFine‐needle aspiration (FNA) biopsy findings are presented in three cases of localized fibrous tumor of pleura (LFTP). Clinically, two of the tumors behaved benignly, although one showed frequent mitoses and foci of necrosis. The third tumor exhibited local aggressiveness as evidenced by rib destruction. Cytologically, these tumors exhibited a wide range of cellularity, composed mainly of small, bland oval to spindle cells with moderate numbers of stripped nuclei. Small bits of collagen were seen in the smears. In all cases, cell blocks were instrumental in making the diagnosis. Previous cytologic descriptions of the tumor are briefly reviewed and the cytologic differential diagnosis is discussed. The peripheral location of this uncommon tumor makes it an ideal target for FNA biopsy. © 1992 Wiley‐Liss,

摘要:

AbstractFine‐needle aspiration biopsy is a well‐established procedure in the detection of various neoplastic processes. However, there are only limited reports on the efficacy of this technique in nonneoplastic conditions. In this study, fine‐needle aspiration cytology findings of bone and soft tissue lesions in 11 patients with tuberculosis are reported. Spine, scapula, chest wall, flank areas, tibia, ring, and index fingers were the sites of fine‐needle aspiration biopsies. The age of the patients ranged from 21 to 65 years. Granulomatous reaction with or without caseation necrosis was seen in 73%. The aspirated material was acellular or predominantly composed of necrotic material and inflammatory infiltrates in 27%. Acid‐fast bacilli (AFB) could be demonstrated in 64%. Culture for Mycobacterium tuberculosis was positive in 83%. This study supports previous suggestions that fine‐needle aspiration biopsy is a simple alternative to open biopsy for the diagnosis of TB of bone and soft tissue lesions. © 1992 Wil

摘要:

AbstractFine‐needle aspiration (FNA) cytology of lymph nodes in malignant lymphoma is fraught with difficulty. In certain clinical situations, cytology has been documented to be useful in patients with malignant lymphoma. The intent of our investigation was to determine the accuracy of a multiparameter approach in diagnosing lymphoma. We reviewed the results of FNA cytology combined with the immunocytochemistry and, in some cases, the Southern blots of aspirated cell suspensions obtained from 86 suspected lymphoma patients who subsequently underwent surgical biopsy of the aspirated site. In four cases, in which FNA was unable to retrieve sufficient material for diagnosis, the histology showed extensive fibrosis. When the FNA diagnoses were compared with the histologic diagnoses, the diagnosis concurred in 69 cases (56 malignant lymphomas, 12 reactive, 1 atypical lymphoid proliferation). There was one false‐positive, six false‐negatives, and eight cases diagnosed as atypical lymphoid proliferation. Overall accuracy was 91%. There were two types of false‐negative cases: those in which a diagnosis of another malignancy or unspecified malignant neoplasm was made and those that were diagnosed as reactive when the histology showed lymphoma. In seven cases, the DNA rearrangement studies of the antigen receptor genes were successfully performed on the aspirated cells and were useful in establishing lineage and clonality of both B and T lymphoid cells.Our study indicated that the use of a multiparameter approach in the diagnosis of malignant lymphoma by FNA enhanced the accuracy of diagnosis of the non‐Hodgkin's lymphomas. In Hodgkin's disease, no benefit was derived from the approach. © 1992 Wiley

摘要:

AbstractA series of 15 cases of rhabdomyosarcoma diagnosed by fine‐needle aspiration biopsy (FNAB) and confirmed by histopathology is reviewed. Cytologically, the tumors were composed of a variable mixture of cells, which according to the degree of differentiation were categorized as early, intermediate, or late rhabdomyoblasts. Histologically, the tumors were divided into embryonal 9, monomorphic round cell 4, and alveolar rhabdomyosarcoma 2. Comparison of histological and cytological features revealed that embryonal types were composed mainly of early rhabdomyoblasts. Recognition of these patterns may be helpful in FNAB diagnosis of rhabdomyosarcoma. © 1992 Wiley‐Liss,

摘要:

AbstractThe fine‐needle aspirates of two cases of noninfiltrating papillary carcinoma (PC) and three examples of early invasive PC of the breast were examined. In three cases in which the tumors displayed cuboidal or polygonal cells the aspirates showed papillalike clusters of tumor cells with relatively “strong” cellular cohesiveness. Single and small aggregates of tumor cells as well as hemosiderin‐laden or foamy macrophages were also present. Aspirates from the two PCs predominantly consisting of tall columnar epithelial cells revealed only monolayered and multilayered epithelial fragments with folding in one case. In the other case large epithelial fragments and small tight clusters of polygonal tumor cells were present. No bipolar nuclei of myoepithelial cells were identified in all cases. No specific cellular features permitting the differentiation between noninfiltrating and early invasive breast PCs were identified in this small series. Staining for carcinoembryonic antigen using the peroxidase‐antiperoxidase technique was performed on aspiration smears of three cases. It revealed a positive cytoplasmic reaction in two cases. © 1992 Wiley
