[Interstitial cells of Cajal: another contribution to modern medicine]

The contributions of Santiago Ramon y Cajal to Modern medicine are innumerable. This large scientist and humanist, a man ahead of his time, spoke for the first time such concepts as angiogenesis, which represents one of the most innovative fields for oncology today, in addition to conducting experimental research on the degeneration and regeneration of the nervous system by which laid the foundation morphofunctional of neuroscience today. In this case, we wanted to remember the significance of the discovery of so-called <<interstitial cells of Cajal>>, which have been involved in multiple processes and digestive diseases we collect, and especially his recent relationship with gastrointestinal stromal tumors with the therapeutic implications this could bring.

[Meckel's diverticulum and gastrointestinal stromal tumor: an unusual association]

Meckel's diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract. Bleeding from Meckel's diverticulum is the most common clinical presentation, especially in childhood. In adults, manifestations include a broad spectrum of symptoms ranging from an incidental finding in surgery, iron deficiency anemia of unknown etiology, and acute abdomen due to mechanical complications of the diverticulum. Neoplastic transformation has been reported, but gastrointestinal stromal tumors are exceptional in this location. We report a case of gastrointestinal stromal tumor in Meckel's diverticulum, complicated by perforation.
