Answer

Biopsies are normally not indicated for small subcutaneous lesions, because the entire tumor is usually removed. All imaging techniques have been combined with fine-needle aspiration (FNA); this combination increases the accuracy of diagnosis. Obtaining tissue samples from different tumor components is important, because it provides samples for histopathologic analysis by means of various techniques, including fluorescence in situ hybridization (FISH).
