Abstract
A-56-years-old male patient with carcinoma of the right tonsil was treated initially by irradiation, Linac x-ray 7, 000 rads, being combined with administration of anticancer drugs, Endoxan, Mitomycin-C and FT-207. But about 14 months after irradiation, the recur-rence of the carcinoma of the hypopharynx was found clinically. A few days later since the recurrence was observed, he suddenly complained of severe abdominal pain and dis-tension. At emergency operation, it was revealed that his complaints were caused by an acute diffuse suppurative peritonitis due to the perforation of the duodenal ulcer, from which he had never been suffered.
Fortunately, a month after the laparotomy, the ulcerated tumor in the right hypo-pharynx had disappeared macroscopically. Therefore he had been discharged without treatment regarding to the tumor of the hypopharynx.
However, nine months later he complained of difficulty of swallowing because of the recurrence of the tumor. And then total laryngectomy and excision of the tumor of the hypopharynx was performed.
We presumed that the tumor had regressed for nine months because his immunological reactivity was increased by the severe inflammation, namely, an acute diffuse suppurative peritonitis.
