This fascinating monograph on the technique of fine-needle biopsy was prepared by Dr. Söderström after ten years of experience in this method, and diagnosis of aspirations from 6,000 patients. The material included aspirates from effusions, lymphatic tissue, salivary glands, thyroid, breast, lung, spleen, liver, kidney, and prostate.
