Reinfection Diagnosed by Endoscopic and Histologic Recurrence in a Patient with Gastric Mucosa-Associated Lymphoid Tissue Lymphoma.

infection is a major cause of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Successful eradication can induce a complete remission (CR); however, it takes a long time. In this case, the recurrence of gastric MALT lymphoma was observed by endoscopic and histologic findings during a 11-year follow-up and due to reinfection twice.

[A case of a gastrointestinal stromal tumor of the rectum effectively treated with continuously-administered regorafenib after failure of imatinib and sunitinib].

Regorafenib is recommended as a third-line treatment for unresectable gastrointestinal stromal tumors (GIST). It is usually administered in a repeating cycle of three-weeks on and one-week off. We describe a patient with an unresectable GIST in the pelvic cavity who complained of pelvic pain while taking the one-week break from regorafenib administration.
