Using cell size, cell density, and microscopic growth pattern, 20 duodenal stromal tumors were initially separated into benign and malignant categories. The 10 histologic benign tumors had uniform spindle cells, low cellularity, and an organoid pattern. All had round eosinophilic collagen blobs scattered among the spindle cells, were 4.5 cm or less in maximum diameter, and had two or fewer mitoses per 50 high-power fields (HPF). None metastasized or recurred during a median follow-up of 7 years… CONTINUE READING
