Malakoplakia is a rare chronic granulomatous disease found in the genitourinary tract, mainly. It is considered to be related to immunosuppression and/or infectious processes. We would like to present an operative case of cecal malakoplakia in a patient with a history of surgical resection and chemotherapy for cervical cancer. A 74-year-old female patient visited our hospital for 1-year follow-up after operation and chemo-radiotherapy for cervical cancer. An infiltrative mass of 6 cm, between the cecal base and the right psoas muscle, was observed on computed tomography. An ileocectomy was performed for diagnosis. Histopathologic examination revealed cecal malakoplakia. After surgery, based on previous reports, antibiotics therapy was added. Then the patient was discharged and treated in the outpatient clinic. To our knowledge, a rare case has been described of cecal malakoplakia during observation after surgery and chemo-radiotherapy for cervical cancer. Malakoplakia is known to be related to immunosuppressive condition. Therefore, our case suggests that close observation should be made in patients on immunosuppressive condition, such as chemotherapy.

Background: Although sarcopenia has been reported to predict survival in cancer patients, its impact on patients who received immune checkpoint inhibitors (ICIs) has not been thoroughly investigated. This systematic review aimed to assess the long-term oncologic impact of sarcopenia on patients who received ICIs. Methods: A systematic review of studies indexed in the PubMed, Embase, and Cochrane databases, up to April 1, 2021, was conducted. Studies that reported hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) based on sarcopenia in patients treated with ICIs were included. The inverse variance method was used with a random-effects model for data analysis. Results: A total of 1284 patients from 14 studies were included. Among the patients who received ICIs, patients with sarcopenia had a significant increase in overall mortality compared to patients without sarcopenia in univariate analyses (HR = 1.66, 95% CI = 1.20–2.29, p = 0.002) and in adjusted HRs (HR = 1.55, 95% CI = 1.15–2.10, p = 0.004). The same results were obtained for PFS by both univariate analysis (HR = 1.75, 95% CI = 1.37–2.23, p < 0.001) and adjusted HRs (HR = 1.63, 95% CI 1.28–2.09, p < 0.001). Conclusions: Sarcopenia appears to be an effective biomarker for predicting long-term oncologic outcomes in patients receiving ICI therapy and hence plays an important role when making treatment decisions. However, the fundamental role of this association with survival should be further investigated in large cohorts and clinical trials.

Introduction Leiomyomatosis peritonealis disseminata is a very rare benign condition of the peritoneal cavity that may mimic peritoneal carcinomatosis or metastatic leiomyosarcomas. It mainly develops in association with pregnancy, but is also rarely associated with endometriosis. Case presentation A 31-year-old Asian woman presented to our hospital with abdominal pain in the right lower quadrant. Her abdominopelvic computed tomography scan showed a 1.2cm-sized nodule at the appendiceal tip, but no other abnormal findings. We suspected acute appendicitis and performed an exploratory laparoscopy. Her appendix was enlarged at the tip portion. Also noted were blood-colored fluid collections in her pelvic cavity and bilateral ovarian cysts. Additionally, several small whitish firm solid nodules, ranging from 0.5 to 1.0cm in size, were present on her pelvic peritoneum. Her histological examination confirmed that the endometriosis of her appendix coexisted with leiomyomatosis peritonealis disseminata. Conclusions We report a case involving a 31-year-old woman with acute symptoms of endometriosis of the appendix associated with leiomyomatosis peritonealis disseminata. Appendiceal endometriosis with leiomyomatosis peritonealis disseminata presenting as acute appendicitis is extremely rare. To the best of our knowledge, this is the first such case reported in the literature.

This report describes an 18-year-old woman presenting with abdominal distension, left flank pain, and hypertension. She had a huge abdominal mass, diagnosed as a mesenteric desmoid-type fibromatosis, causing compression of the left external iliac vessels and ureter, as well as elevated renin concentration and hypertension. After surgical removal of the mass, all signs improved including hypertension.

병합임신이란 자궁강내 임신과 자궁외임신이 동반되는 것으로 정의된다. 자연발생률은 1/30,000 정도로 매우 낮으나 보조생식술을 시행한 경우 1/7,000 정도로 발생 위험이 증가하므로 보조생식술을 시행하였을 경우에는 반복적인 초음파 관찰을 통해 조기 진단하는 것이 중요하다. 치료로는 수술적, 약물적 방법이 있고 이 중 안전하게 자궁내임신을 유지시키면서 효과적으로 치료하는 방법이 늘어나는 추세이다. 저자들은 보조생식술을 시행한 환자에게서 발생한 자궁각 임신을 동반한 병합임신에서 자궁각내 염화칼륨을 주입하여 선택적으로 태아감축술을 시행한 후 정상 자궁내임신을 유지하여 만삭분만에 성공한 증례를 경험하였기에 간단한 문헌고찰과 함께 보고하는 바이다.

Objective: Aromatase is the key enzyme for the conversion of C19 steroids into estrogen in certain human tissues. We studied to evaluate the aromatase expression in eutopic endometirum and endometriotic lesion and its relationship to clinical and laboratory parameters. Methods: The study included 78 cases of endometriotic lesion and 14 cases of eutopic endometrium and 30 cases of normal uterine endometrium obtained through laparoscopic surgery and curettage. The frozen tissue specimens were examined by immunohistochemistry using aromatase. Clinical symptoms, laboratory findings, and operative findings were analyzed and compared in according to aromatase expression. Results: We observed positive immunohistochemical expression for aromatase in endometriotic lesion from 46/78 patients (59.0%). Aromatase expression was elevated in comparison to eutopic endometrium (5/14 patients, P=0.032) and the difference was more pronounced when eutopic endometriums from patients with endometriosis were compared with those of healthy controls (2/30 patients, P
