    Abstract : Cysts, closed sac-like structures filled with fluid or air, can form anywhere in the body. In the majority of cases, cysts are benign (not cancerous). However, these structures can also be precursors of cancer, pointing to the location where cancer can originate. READ MORE

  4. 2. Fine needle aspiration diagnosis of spindle cell tumors of soft tissue, including the use of ancillary methods, and correlation with clinical data

    Author : Henryk Domanski; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patologi allmän ; patologisk anatomi; General pathology; pathological anatomy; spindle cell lipoma; soft tissue; spindle cell tumors; Medicine human and vertebrates ; Medicin människa och djur ; schwannoma; neurilemoma; leiomyosarcoma; immunocytochemistry; FNA; fine needle aspiration; dermatofibrosarcoma protuberans; elastofibroma dorsi; Cytology; electron microscopy;

    Abstract : Fine needle aspiration cytology (FNAC) is gaining increased popularity in the diagnosis of soft tissue lesions. FNAC used as a primary examination method to obtain a morphologic diagnosis, has been part of the diagnostic work-up of patients admitted to the Musculoskeletal Tumor Center of the Lund University Hospital since 1972.

  5. 3. Comparison of stereotactic fine needle aspiration biopsy and core needle biopsy in breast lesions

    Author : Karin Leifland; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Purpose: The purpose of this study was to evaluate the diagnostic value of two biopsy methods by comparing stereotactic fine needle aspiration biopsy (S-FNAB) with stereotactic core needle biopsy (S-CNB). The biopsies were performed by the same radiologist, in the same breast lesion on the same occasion, in order to establish which method that best can be recommended in different kind of mammographically detected lesions.

    Abstract : Fine needle aspiration (FNA) cytology is accepted for diagnosing malignant tumours in adults. However, it has been slow in gaining acceptance among paediatricians and has only been used at some centres in the routine diagnosis of childhood tumours. READ MORE

  7. 5. Electron Microscopy in Diagnostic Pathology with Reference to Mesenchymal Tumors

    Author : Birgitta Carlén; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; synovial sarcoma; Kaposi´s sarcoma; epithelioid sarcoma; parachordoma; alveolar soft part sarcoma; small cell malignant tumors of childhood and adolescence; cultured cells; surgical specimens; Transmission electron microscopy; fine needle aspiration; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Abstract : The experience acquired over a period of 15 years of diagnostic electron microscopy of fine needle aspirates and surgical specimens constitutes the base for this thesis. Some of the tumors analyzed represent rare soft tissue tumors, and consequently not very often ultrastructurally described. READ MORE
