Insulinoma Causing Liver Metastases 15 Years after Initial Surgery, Accompanied by Glomerulonephritis
Figure 1
(a) Microscopic features of the excised insulinoma. Histomorphologically, a solid pattern was predominated. Moderate sized tumour cells formed solid cellular sheets, poorly defined trabeculae and pseudoglandular structure (×200 magnification). (b) Tumour cells showed mild atypias with nucleolar enlargement a slightly increased nuclear/cytoplasmatic ratio and nuclear crowding. No mitotic activity was observed but the proliferative rate was found slightly increased (×400 magnification).
