Background: Diffuse uterine leiomyomatosis is a rare disease in which countless, poorly defined, and small nodules are present in most parts of the uterine myometrium. It frequently occurs in fertile women and causes infertility. A deep, median, longitudinal incision of the uterine corpus with the opening of the endometrial cavity, "extensive myomectomy," is required to restore fertility. However, myomectomy may also be a risk factor for perinatal complications. We present a rare case of adhesive small bowel obstruction after extensive myomectomy for diffuse uterine leiomyomatosis., Case: A 37-year-old primigravida presented with sharp epigastric pain and vomiting at 21-week gestation. The patient had a history of extensive myomectomy for diffuse uterine leiomyomatosis. Abdominal radiography revealed moderate air fluid levels in the small intestine, and the patient was diagnosed with adhesive small bowel obstruction. The patient was also diagnosed with placenta previa. Bowel rest with intestinal tube was continued until delivery. Cesarean section was performed at 32-week gestation due to (i) prolonged fasting and total parenteral nutrition for conservative treatment and (ii) fear of sudden massive bleeding from placenta previa. Because the ileum was strongly adherent to the uterine scar from the previous myomectomy, adhesiolysis and enterectomy were performed. The placenta was uncomplicatedly delivered and the hemorrhage was well-controlled., Conclusions: Pregnancy with a history with extensive myomectomy for diffuse uterine leiomyomatosis should be carefully monitored because of the occasional occurrence of adhesive small intestine obstruction during pregnancy., Competing Interests: The authors declare no conflicts of interest related to this manuscript., (Copyright © 2022 Yuri Suminaga et al.) more...

Aplastic anemia is a rare blood disorder characterized by pancytopenia and hypocellular bone marrow. In patients with aplastic anemia, pancytopenia sometimes worsens during pregnancy, and relapse of aplastic anemia in pregnancy is common. Nevertheless, only supportive care with blood products is the mainstay of treatment of aplastic anemia in pregnancy. Thus, the obstetric management and treatment of aplastic anemia in pregnancy is extremely challenging. We herein report the first case of a pregnant woman complicated with aplastic anemia who was successfully treated with eltrombopag, a thrombopoietin receptor agonist. A 27-year-old primigravida woman who had a history of aplastic anemia refractory to immunosuppressive therapy and was treated with eltrombopag became pregnant. Eltrombopag treatment was continued after weighing the benefits and potential risks. Throughout pregnancy, the woman's pancytopenia did not progress, and she delivered a 2336 g baby vaginally at 38 weeks of gestation. Her postpartum outcome was uneventful, and the neonate did not develop thrombocytosis. Since the efficacy and safety of eltrombopag in pregnancy has not yet been established, its routine use should be avoided. However, if limited to refractory cases and with adequate maternal and fetal monitoring, including neonatal blood examinations, the use of eltrombopag for patients with aplastic anemia during pregnancy may be acceptable and result in favorable maternal and fetal outcomes., Competing Interests: No author claims financial conflicts of interest., (Copyright © 2022 Yuri Suminaga et al.) more...

We report a case of torsion in an otherwise-normal ovary with a giant hematosalpinx. A 23-year-old woman presented with complaints of abdominal pain and nausea. At initial visit, there was few abnormal findings of imaging tests, and we made a diagnosis of ovarian hemorrhage. Three days later, she came back with increased symptoms, and we detected the mass of a complex solid cystic structure with a unilocular cyst much larger than solid component. A diagnostic laparoscopy was performed immediately, and we could make a diagnosis of torsion in an otherwise-normal ovary with a giant hematosalpinx. We performed a salpingectomy and could preserve her ovary. This is the first case of torsion in an otherwise-normal ovary with a giant hematosalpinx which enlarged to a greater extent than the ovary., Competing Interests: The authors have no conflicts of interest relevant to this article., (Copyright © 2021 Sae Yu et al.) more...

Ovarian tumors can get extremely giant to occupy the whole abdominal cavity. We report a case of 36 kg solid ovarian tumor, which was the largest ovarian solid tumor that have been ever reported. A 54-year-old woman presented to our hospital with a chief complaint of markedly distended abdominal wall. Preoperative imaging examinations revealed that most of the tumor was uniform and its density was like that of subcutaneous fat. Pleural effusion was detected in the right thoracic region. We organized a multidisciplinary team and successfully resected the right adnexa. The patient had an uneventful postoperative course, and she was discharged on the 7 th postoperative day and diagnosed with a fibroma of the ovary with Meigs syndrome. A comprehensive literature search revealed 48 cases of extremely giant ovarian tumor in these 20 years. Six out of 48 cases are solid. Twelve out of 48 cases are malignant or borderline malignant, and patients' age and tumor size/weight were not related to the frequency of malignancy/borderline malignancy. As many as 4 out of 48 patients died before their first hospital visit or early after surgery. Clinicians should consider a considerable high mortality and frequency of severe surgical complications when planning the treatment strategy for extremely giant ovarian tumors., Competing Interests: The authors declare that there is no conflict of interest regarding the publication of this article., (Copyright © 2021 Miyu Tanaka et al.) more...

A well-known typical feature of ectopic pregnancy is an evident gestational sac structure outside of the uterus. However, some cases show atypical appearance that is described as a heterogeneous hypervascular mass. We report two cases of ectopic pregnancy that presented heterogeneous findings mimicking gestational trophoblastic diseases but were correctly diagnosed as ectopic pregnancies on MRI. The first case was an interstitial pregnancy in which the patient underwent surgical treatment. The second case was a cesarean scar pregnancy that was treated conservatively but showed spurious enlargement of pregnancy-related lesions after the treatment. Both cases lacked myometrial invasion on MRI, and the patients were diagnosed with ectopic pregnancies. Invasive findings on MRI may discriminate ectopic pregnancy from trophoblastic tumors and avoid unnecessary hysterectomy., Competing Interests: The authors declare that there is no conflict of interest regarding the publication of this article., (Copyright © 2020 Haruka Suzuki et al.) more...

The pregnancies of childhood cancer survivors who have received uterine irradiation are associated with a high risk of several obstetrical complications, including placenta accreta. The present case was a 26-year-old pregnant woman with a history of myelodysplastic syndrome treated with umbilical cord blood transplantation following chemotherapy and total body irradiation at the age of 10. Despite every possible measure to prevent preterm labor, uterine contractions became uncontrollable and a female infant weighing 892 g was vaginally delivered at 27 +4 weeks of gestation. Under the postpartum ultrasonographic diagnosis of placenta accreta, we selected to leave the placenta in situ . Although emergency bilateral uterine artery embolization was required, complete resorption of the residual placenta was accomplished on the 115 th day postpartum. Our experience highlighted the following points. (1) The expectant management of placenta accreta arising in an irradiated uterus may not only fulfill fertility preservation, but may also reduce possible risks associated with cesarean hysterectomy. (2) Due to extreme thinning of and a poor blood supply to the myometrium, reaching an antepartum diagnosis of placenta accreta in an irradiated uterus is difficult. (3) The recurrence of placenta accreta in subsequent pregnancies needs to be considered after successful preservation of the uterus., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2019 Nanayo Sasagasako et al.) more...

Esophageal cancer rarely coincides with pregnancy, and only five cases have been reported thus far. The management of esophageal cancer during pregnancy is extremely challenging due to its aggressive nature. We herein report a case of recurrent esophageal cancer in pregnancy. A 41-year-old multigravida with a history of esophageal squamous cell cancer treated with esophagectomy and perioperative chemotherapy was diagnosed with local recurrent carcinoma of the residual esophagus at 16 weeks of gestation. The patient strongly desired to continue the pregnancy, and concurrent chemoradiation therapy (CRT) consisting of 50.4 Gy of radiation, cisplatin, and 5-fluorouracil was carried out from 19 weeks of gestation. CRT was dramatically effective, and the recurrent lesion disappeared. At 38 weeks of gestation, she underwent cesarean section and delivered a healthy female baby. Both maternal and fetal courses were satisfactory, and the patient has been free of disease for 12 months. This is the first case of recurrent esophageal cancer in pregnancy in which CRT was completed without reducing treatment intensity and led to a complete response. Nevertheless, little is known regarding the safety and possible adverse effects of CRT on the fetus. Therefore, deliberate selection of patients and long-term follow-up of the child are necessary. more...

Pulmonary edema caused by severe preeclampsia can be an indication for pregnancy termination. We aimed to investigate whether noninvasive positive-pressure ventilation (NPPV) was useful for preeclampsia-induced pulmonary edema. Three cases of preeclampsia-induced pulmonary edema managed with NPPV in our institute were reviewed retrospectively. A literature review was conducted regarding NPPV usage during pregnancy. NPPV was initiated at 30, 20, and 24 weeks of gestation in the 3 cases. In all cases, NPPV slowed the progression of pulmonary edema and succeeded in delaying pregnancy termination by 17 days on average. Maternal outcomes were positive, and no intubation was required. Between 1994 and 2017, there were 11 articles describing 12 cases in which NPPV was applied for pulmonary edema during pregnancy. However, there has been no case of NPPV management of preeclampsia-induced pulmonary edema thus far. Maternal and fetal outcomes were positive in these 12 cases. NPPV may contribute to prolonging pregnancy in patients with poor oxygenation due to preeclampsia-induced pulmonary edema. However, patients should be closely monitored, and the decision to intubate or terminate the pregnancy should be made without delay when the maternal or fetal condition worsens. more...

Pneumonia in pregnancy is associated with adverse maternal and foetal outcomes, and intensive treatment with appropriate antibiotics is essential. However, cases caused by pathogens that are resistant to antibiotics suitable for the developing foetus are challenging. We herein report a case of macrolide-refractory Mycoplasma pneumoniae pneumonia in pregnancy. A 40-year-old multigravida with twin pregnancy complained of cough and fever at 13 weeks of gestation and was diagnosed with pneumonia. Even though empiric treatment with ceftriaxone and oral azithromycin was started, her condition deteriorated rapidly. The findings of chest computed tomography suggested Mycoplasma pneumoniae pneumonia. Since azithromycin did not work, this strain was considered to be macrolide-refractory. Garenoxacin, an oral quinolone, was selected and was dramatically effective. The use of quinolone could be justified with the emergence of drug-resistant bacterial/atypical pneumonia and in the maternal life-threatening condition. more...

Pneumocystis pneumonia (PCP) is a life-threatening opportunistic infection that sometimes occurs in immunocompromised patients with human immunodeficiency virus (HIV). Here, we report two extremely rare cases of PCP in non-HIV pregnant women who underwent chemotherapy for malignant lymphoma. Case  1 is a 34-year-old primigravida who was diagnosed with Hodgkin's lymphoma. She received ABVD chemotherapy and developed PCP at 37 weeks of gestation. After the onset of PCP, emergent cesarean section was performed due to a nonreassuring fetal status. Case  2 is a 31-year-old multigravida with diffuse large B-cell lymphoma who was administered R-CHOP chemotherapy. At 34 weeks of gestation, she complained of dyspnea and developed PCP. She delivered her baby vaginally immediately after the onset of symptoms. Both patients were treated with sulfamethoxazole-trimethoprim (ST) and recovered shortly thereafter. The babies' courses were also uneventful. PCP remains a serious cause of death, especially in non-HIV patients, and, therefore, appropriate prophylaxis and a prompt diagnosis are imperative. more...
