Özet
Although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, but nonneoplastic reactive processes may also involve the gastrointestinal tract and mesentery. Some more aggressive neoplasms located in same area, such as fibromatosis or gastrointestinal stromal tumors may be cause of diagnostic confusion. Reactive nodular fibrous pseudo tumor (RNFP) of the gastrointestinal tract and mesentery is a recently recognized entity. Here we present one such lesion in 71 years-old- man with a history of abdominal surgery. The tumor was firm, tan– white colored, ranged in size 19.5 cm in greatest dimension, and was grossly well circumscribed. Histologically it is composed of spindle-shaped cells resembling fibroblasts arranged haphazardly or in intersecting fascicles, embedded in a collagen-rich stroma with sparse intralesional lymphoid cells frequently arranged in aggregates. We present a case of this entity have largest tumor and also due to the rarity.
