[Ganglioneuroma of the duodenum]. / Ganglioneuroma del duodeno.

Ganglioneuroma is an exceptional benign tumour of the duodenum and only three cases have been described previously. We report the case of a 71-year-old male in whom this pathology was incidentally discovered, as it usually happens with this type of tumour. Within rare duodenal nonepithelial tumours, gangliocytic paraganglioma is a fairly well defined entity characterized by a proliferation of neurons, Schwann cells, and endocrine-like epithelial cells. Ganglioneuroma lacks this last type of cells and represents and even rarer finding within tumoral pathology of the duodenum. The histopathogenesis of this tumor is discussed and there are theories that defend an hamartomatous origin against a neoplastic nature.

[A chronic intrascrotal inflammation secondary to free foreign bodies in the tunica vaginalis]. / Inflamación crónica intraescrotal secundaria a cuerpos extraños libres en túnica vaginal.

We report a case of granulomatous reaction to intrascrotal foreign body (vegetable fibers) that presented as an inguinal mass in a patient who had been treated for perforation of the jejunum loop incarcerated in inguinal hernia. To our knowledge a similar case has not been reported in the literature.
