Resumen

El tumor fibroso calcificante (TFC) es una inusual lesión benigna de origen mesenquimal que puede presentar características similares a otros tumores más comunes. El caso involucra a una mujer de 36 años con un tumor en el yeyuno proximal, inicialmente sospechoso de ser un tumor del estroma gastrointestinal (GIST). Se realiza una resección quirúrgica, revelando un nódulo bien delimitado en el borde antimesentérico con características microscópicas típicas de TFC. Las células tumorales presentaban positividad para CD34 y negatividad para demás marcadores, diferenciándolo de otras neoplasias. El TFC puede confundirse con tumores más comunes debido a su apariencia, pero un diagnóstico preciso respaldado por inmunohistoquímica es esencial. La extirpación quirúrgica completa suele ser curativa.

Abstract

Calcifying fibrous tumor (CFT) is a rare benign lesion of mesenchymal origin that may present similar characteristics to other more common tumors. We present the case of a 36-year-old woman with a tumor in the proximal jejunum, initially suspected to be a gastrointestinal stromal tumor (GIST). Surgical resection was performed, revealing a well-demarcated nodule at the anti-mesenteric border with microscopic features typical of a calcifying fibrous tumor. The tumor cells were positive for CD34 and negative for other markers, differentiating it from other neoplasms. Calcifying fibrous tumors can be confused with more common tumors because of its appearance, but an accurate diagnosis supported by immunohistochemistry is essential. Complete surgical excision is usually curative.
