RESUMEN
Lymphangioleiomyomatosis (LAM) is one of the presentations of perivascular epithelioid cell neoplasm that is frequently complicated by tuberous sclerosis complex (TSC). Here, we report an uncommon case of uterine LAM treated with everolimus, which is a mechanistic target of rapamycin (mTOR) inhibitor. A 42-year-old female patient (gravida 0) with a history of TSC presented with abdominal pain. Pelvic magnetic resonance imaging showed multiple masses in the uterine myometrium, suggesting tumors that may contain internal hemorrhagic components. The lesions were suspected as the root cause of her symptoms. After everolimus was administered for a previously diagnosed renal angiolipoma, her uterine tumors temporarily decreased in size. Subsequently, laparoscopic hysterectomy and bilateral salpingectomy were performed since she could not tolerate everolimus for a long period due to the medication's side effects. Furthermore, the patient was diagnosed with LAM through histopathological examination after surgical resection. Therefore, it is advisable to suspect and investigate uterine LAM when a patient with a history of TSC presents with irregular genital bleeding or abdominal pain. Moreover, mTOR inhibitors may be a treatment option, in addition to surgery, in cases of uterine LAM exacerbation.
RESUMEN
Chronic active Epstein-Barr virus (CAEBV) infection characterized by persistent infectious mononucleosis-like symptoms can lead to cardiovascular diseases. We encountered two pregnant women with CAEBV histories complicated with cardiovascular diseases. A 36-year-old woman with a history of myocardial infarction due to CAEBV and coronary artery bypass grafting became pregnant. Her left ventricular ejection fraction (LVEF) decreased, and cesarean section was performed at 36 weeks of gestation. Her LVEF recovered after delivery. A 32-year-old woman with a history of CAEBV and chronic hypertension was diagnosed with mild pulmonary arterial hypertension (PAH) after conception. She strongly desired to continue the pregnancy. She became complicated with severe superimposed preeclampsia at 31 weeks of gestation, and cesarean section was performed. Her PAH did not deteriorate during pregnancy or the postpartum period. Women treated for CAEBV, even with complete remission, require a preconception evaluation focused on the cardiovascular system and careful management of their pregnancy.

OBJECTIVE: The treatment strategy for vaginal intraepithelial neoplasia (VaIN) 2-3 has not been established. This study aimed to investigate the efficacy of imiquimod in VaIN 2-3. METHODS: Electronic databases (PubMed, EMBASE, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials) were searched from their inception until October 2019 and articles reporting imiquimod treatment for VaIN 2-3 were extracted. Additionally, the clinical records of women with VaIN 2-3 who had been treated with imiquimod in Shizuoka General Hospital from January 2016 to May 2020 were investigated. The data from the systematic search and the data from our hospital were analyzed, and a pooled complete response (CR) rate and response rate of imiquimod treatment for VaIN 2-3 were estimated. As a subgroup analysis, the CR rates and response rates were compared between women with and without a history of hysterectomy, and the rate ratio was calculated. RESULTS: Five articles described 28 women with VaIN 2-3 who underwent imiquimod treatment, and nine women with VaIN 2-3 were treated with imiquimod in our hospital. The discontinuation of the treatment was required in only one patient of the reported cases. The pooled CR rate and response rate of imiquimod, regardless of a history of hysterectomy, was 0.76 (95% CI, 0.59-0.87) and 0.89 (95% CI, 0.71-0.97), respectively. In the subgroup analysis, the CR rate in patients with hysterectomy was 0.98 (95% CI, 0.11-1.0) and in those without hysterectomy was 0.60 (95% CI, 0.30-0.84), and the rate ratio was 0.83 (95% CI, 0.48-1.19). The pooled response rates with and without a history of hysterectomy were not estimated, and the rate ratio was 0.83 (95% CI, 0.54-1.09). CONCLUSION: Imiquimod can be an effective treatment for vaginal intraepithelial neoplasia 2-3.

Vaginal intraepithelial neoplasia (VAIN) is a rare disease associated with human papillomavirus infection. High-grade VAIN is typically treated with either excisional or ablative therapy. However, recurrent VAIN lesions are common and these treatments cause vaginal scarring. Recent studies have indicated that 5% imiquimod is an effective treatment for VAIN. The present report describes a case of a woman diagnosed with recurrent VAIN 3 who was treated with a 5% topical imiquimod cream and achieved a complete response after excision and CO2 laser vaporization. A 53-year-old, gravida 5, para 2 postmenopausal woman who was diagnosed with papillary squamous cell carcinoma by biopsy underwent conization, total abdominal hysterectomy and bilateral salpingo-oophorectomy. A histological examination revealed grade 3 cervical intraepithelial neoplasia with free surgical margins. At 3 years after the hysterectomy, the vaginal smear revealed atypical squamous cells, leading to a pathological diagnosis of VAIN 3. Partial vaginectomy was performed, and VAIN 3 was detected in the lesion with positive margins. At 4 months into follow-up, the vaginal smear revealed a high-grade squamous intraepithelial lesion (HSIL), and subsequent biopsy during colposcopy revealed a pathological diagnosis of VAIN 3. At 3 months after CO2 laser vaporization, the vaginal smear revealed HSIL with suspected recurrence and imiquimod treatment was initiated. One sachet of 5% imiquimod cream (0.25 g) was placed in the entire vagina three times per week for 14 weeks with no apparent complications. At 3 years after the treatment, there has been no recurrence. This case demonstrated that topical imiquimod with careful follow-up is an effective treatment for VAIN and is well-tolerated. Further clinical evidence of the effectiveness and safety of imiquimod in patients diagnosed with VAIN is required.
RESUMEN
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 115th 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.
