    Description / Table of Contents: In the last few years, the primary diagnosis of soft tissue tumours has emerged as an important new target for fine needle aspiration (FNA). The purpose of this book is to facilitate the cytological evaluation of FNA smears from soft tissue tumours and to suggest cytological criteria for histotype diagnoses. Its primary aim is to describe and illustrate not only the most common types but also those rare tumours where cytological features have been largely described in case reports and in small series. The diagnostic use of ancillary methods is discussed and illustrated, and, in order to facilitate the diagnostic work-up in FNA samples, smears are also classified according to their principal microscopic patterns.The selection of entities presented, their diagnostic features and differential diagnostic considerations are mainly based on the experience with FNA in the primary diagnosis of soft tissue tumours in patients referred to the Musculoskeletal Tumour Centre at the University Hospital in Lund, Sweden over the last 30 years. The illustrations have mainly been culled from cases in the files of the Department of Pathology and Cytology, Lund University Hospital.Soft tissue tumours are relatively rare and often difficult to correctly diagnose in fine needle aspirates. Therefore, this publication should be welcomed by all cytopathologists involved in the FNA diagnosis of tumours as a valuable addition to their benchside textbooks

    Notes: Abstract Scintigraphic studies of the thyroid with thallium-201 chloride were performed in 46 patients in whom the final diagnosis was established by histology. In dynamic studies of 36 patients, sequential imaging was performed the first 40 min after injection. A single exponential, Cexp(-λt), was fitted to each of the curves generated from apparently pathological and from normal regions in each patient, as determined by earlier conventional scintigrams. To minimize the effects of normal individual variations, the relation between pathological (p) and normal (n) regions in the same patient was emphasized and quantified by two parameters, namely the extrapolated zero-time intercept (C p /C n ) and the time development $${\text{(}}\lambda _p - \lambda _n {\text{)}}$$ of the ratio of couting rates/unit area in the two regions. The turnover appears to be somewhat slower for pathological tissue than for normal tisue. Although this difference was significant on the 5% level for both cancer and adenoma as a group, only the relative disappearance rate $${\text{(}}\lambda _p - \lambda _n {\text{)}}$$ resolved cancer from adenoma and from goiter on the same level. All but one of the differentiated cancers had a increased uptake.

    Notes: Summary In the evaluation of soft tissue tumors primary sarcomas must be differentiated from other malignancies, such as cancer metastases, malignant lymphomas, as well as benign tumors and tumor-like conditions. As far as possible this should be done without open biopsy to avoid local spread. Fine needle aspiration biopsy as opposed to thick needle biopsy utilizes smaller needle diameters up to 0.8 mm with assumed negligible risks of local or distant tumor spread. Such a fine needle aspiration biopsy for cytodiagnosis was supposed to increase the reliability of the preoperative diagnosis. In a consecutive series of 187 patients referred to an orthopedic oncology group because of suspected malignancy fine needle aspiration biopsy was made. In 129 cases with histology and in 49 non-operated cases with at least 2 years of clinical follow-up the reliability of the method is analyzed. In 163 cases the aspirated material was sufficient for a diagnosis and 152 cytological reports were correct regarding the diagnosis of a malignancy contra a benign tumor or tumor-like condition. Thirty-five of 43 malignancies were primary soft tissue sarcomas, 28 of these with a correct cytologic diagnosis of sarcoma. Eight were malignant lymphomas or carcinomas. Fourty-nine patients with 48 benign and one malignant cytological diagnosis were not operated upon. At least 2 years of clinical follow-up confirmed a benign diagnosis in these cases. The total reliability is thus around 85%. Fine needle aspiration biopsy is considered to be a very valuable complement to other investigations in the diagnostic work-up of soft tissue tumors.
