Concurrent Gastric and Pulmonary Mucosa-Associated Lymphoid Tissue Lymphomas with Pre-Existing Intrinsic Chronic Inflammation: A Case Report and a Review of the Literature

Herein, we report a rare case of concurrent gastric and pulmonary mucosa-associated lymphoid tissue (MALT) lymphomas. A 65-year-old man who had been diagnosed with Helicobacter pylori-positive gastric MALT lymphoma received eradication therapy and achieved complete remission. During follow-up, he developed de novo pulmonary MALT lymphoma as a sequela of pulmonary tuberculosis, accompanied by recurrent gastric MALT lymphoma. Polymerase chain reaction (PCR) products of the CDR3 region of the immunoglobulin heavy chain gene showed an overall polyclonal pattern with bands at 400 base pairs (bp) and 200 bp predominant in the pulmonary tissue, as well as two distinctive bands in the gastric tissue at 400 bp and 200 bp. This case suggests that multiorgan lymphomas are more likely to be independent from each other when they are far apart, involve different organ systems, and have independent precipitating factors.

A case of cystic change of pelvic retroperitoneal Schwannoma misdiagnosed as an ovarian tumor / 대한산부인과학회잡지

Retroperitoneal Schwannoma is relatively rare and benign tumor originating from Schwann cell. Schwannomas arising in the retroperitoneum are infrequently reported. The majority of Schwannoma is found incidentally and misdiagnosed for other benign conditions both clinically and radiologically. We report a case of a benign retroperitoneal pelvic Schwannoma which was preoperatively misdiagnosed as an ovarian tumor with brief review of literatures.

A case of ovarian remnant syndrome following total abdominal hysterecomy with bilateral salpingoophorectomy / 대한산부인과학회잡지

Ovarian remnant syndrome is a rare condition which develops when functional ovarian tissue is left in situ after intended bilateral oophorectomy. It produces clinically significant syndrome, namely chronic pelvic pain and dysmenorrhea. Although the true incidence of this syndrome is unknown, an apprant increase in incidence has been reported. We have experienced a case of ovarian remnant syndrome showing chronic pelvic pain and palpable abdominal mass after difficult gynecologic operation. So, we report this case with a brief review of literatures.

A Case of Pseudomyxoma Peritonei / 대한산부인과학회잡지

"Pseudomyxoma peritonei is a clinical entity in which the peritoneal surface and omentum are involved with gelatinous, mucinous implants, and often massive gelatinous ascites. Most cases originate from ruptured ovarian mucinous cysts or appendiceal mucoceles, and involve only the intraperitoneal cavity. But there is much confusion about its etiology, clinical manifestation, treatment, and prognosis. We experienced a case of pseudomyxoma peritonei originating from the mucinous cystic tumor of borderline malignancy in unilateral ovary with rupture. A case of pseudomyxoma peritonei is reported with a brief review of the literature."
