Popis:	We report a case of an intranodal schwannoma in a 79-year-old woman. The patient underwent a left colectomy for a colonic adenocarcinoma, with regional lymph node dissection. Macroscopic examination of the specimen revealed a well-circumscribed 4 cm nodule located in the pericolic fat. Macroscopically, it was interpreted as a metastatic lymph node. Microscopically, the nodule was composed of a proliferation of bland spindle cells, was immunohistochemically positive for S100 protein, and negative for smooth muscle actin, desmin, and cytokeratin. The pathological findings led to the diagnosis of a very rare case of primary schwannoma of the lymph node.
