RESUMO
The incidence of synchronous carcinoma of the colon and rectum is rising and ranges from 0.6 to 11% in the international literature. We present a study on 410 patients with colorectal cancer; 10 patients (2.4%) had synchronous carcinoma. The group of patients with synchronous carcinomas were older than the group with nonsynchronous carcinomas (70.5 versus 67.4 years). The choice of surgery depended on the involved portions of the colon and the distance between the lesions. For tumoral sites in 2 different segments was performed subtotal colectomy, in the other cases (cancers located on one segment) was performed segmental colectomy. The incidence of synchronous tumors is sufficiently high to suggest that the preoperative identification of lesions by either colonoscopy is important for the proper treatment of patients with carcinoma of the colon and rectum and moreover an so high incidence, more the risk of not recognising the disease, especially in the case of small lesions, emphasizes the importance of postoperative endoscopic and clinical controls.

The authors relate upon the so-called Boerhaave's syndrome or spontaneous perforation of the esophagus illustrating 2 cases recently observed. On the basis of their experience and of what has been reported by the literature on this subject the etiopathogenetic and pathophysiologic problems as well as the adequate treatment are debated. Particularly the nature of the lesion, which is a barotrauma lesion, the urgency of the surgical treatment, and the severity of the prognosis are pointed out.

Estrogen and progesterone receptors were studied in 70 cases of human colorectal cancer by a cytochemical technique. 28.5% of the cases were estrogen-receptor positive and 42.8% progesterone-receptor positive. There was no difference between the sexes for estrogen receptors but the women had more tumours with progesterone receptors than men. The presence of receptors is unrelated to the differentiation of the tumor. More colon tumours were positive than those of the sigma and rectum. The concentration of cells with receptors in positive cancer cases tended to be low or medium-low.
