RESUMO
Intussusception is an infrequent cause of mechanical intestinal obstruction in the adult. We present herein two clinical cases of intussusception with different etiologies. In the first case, the underlying cause was a lipoma, and in the second, it was metastasis from melanoma. In both cases the intussusception was identified through computed tomography and treatment was intestinal resection. Pathologic anatomy provided the definitive diagnosis. Etiology is diverse and it is more common for obstruction to be due to organic lesions that are malignant at the level of the colon and benign at the level of the small bowel. Currently there are more preoperative diagnoses thanks to the advances made in imaging study techniques. Intestinal resection continues to be the treatment of choice in the majority of cases, because of the high percentage of malignant lesions as the underlying cause.

The desmoplastic small round cell tumor is infrequent.That mainly affects male youngsters and is normally located at the abdomino-pelvic cavity, being its clinic unspecific. The diagnosis is confirmed by the presence of a specific chromosomal translocation: t (11; 22), (p13; q12). As to its treatment, it is mostly recommended to follow a multimodal aggressive one. We present the case of a man, whose atypicality is due to his advanced age (63 years old) and the symptoms he presents (lumbar ache).
