Obinutuzumab is used for the treatment of chronic lymphocytic leukemia. So far there are no data of using this for retreatment in patients who have received it previously. We introduced obinutuzumab for the retreatment in a chronic lymphocytic leukemia patient, who had first achieved partial remission with it and eventually relapsed over a course of 2.5 years. After retreatment with single-agent obinutuzumab, the patient achieved a partial remission again within one cycle and continues to maintain the response status. This case is a platform for considering obinutuzumab as a viable option for retreatment of chronic lymphocytic leukemia patients who have received it before, similar to the pattern of use for other anti-CD20 monoclonal antibodies in this disease, including rituximab.

Phlegmonous gastritis is an uncommon acute bacterial infection of the stomach that carries a fatal prognosis in spite of the advent of antibiotics. A high index of suspicion is required in patients with risk factors. An immunocompromised state is identified as one of the most important risk factors. We hereby report a case of successful antimicrobial treatment of phlegmonous gastritis in a patient who was receiving intensive chemotherapy for acute myelogenous leukemia. We have also carried out a review of literature over the past ten years. Streptococcus pyogenes is identified as the most common causative organism, and patient presentation is usually nonspecific. Conservative treatment with prompt institution of antibiotics can lead to rapid resolution in the majority of patients.
