[Possibilities of morphological diagnosis of amyloid in the subcutaneous adipose tissue biopsy specimens].

The SAT biopsy specimens are characterized by the minimal risk to a patient and by the easy way of sampling and are a frequent subject for screening biopsies. In addition to the type of amyloid, the volume, quality, and method of processing the biopsy specimen are responsible for the diagnostic value of SAT examination. The study of squashed native specimens stained with Congo red is most informative when using polarized light.
