In vitro fertilization outcomes in women with surgery induced diminished ovarian reserve after endometrioma operation: Comparison with diminished ovarian reserve without ovarian surgery

OBJECTIVE: To compare the in vitro fertilization (IVF) outcomes between women with diminished ovarian reserve (DOR) after endometrioma operation and women with DOR without ovarian surgery. METHODS: This retrospective case-control study included 124 women aged under 40 and had DOR (serum anti-Müllerian hormone level <1.1 ng/mL or antral follicle count ≤6). They participated in fresh first and/or second IVF cycles between March in 2010 and December in 2015. Basal characteristics and IVF outcomes were compared between 47 cycles (32 women) with surgery-induced DOR and 119 cycles (92 women) with DOR without ovarian surgery. RESULTS: Basal characteristics were similar in both groups except that the median ages were lower in the surgery-induced DOR group compared to the DOR group without ovarian surgery. The data regarding the controlled ovarian stimulation and IVF cycle outcomes showed similar result in both groups. Also, clinical pregnancy and live birth rate were not different significantly between two groups. CONCLUSION: In the same condition of DOR, clinical pregnancy and live birth rate were not different significantly between two groups regarding etiology of DOR.

Clinicopathologic evaluation of myofibroblastoma: A study in two hospitals

OBJECTIVE: To report various anatomic locations and clinical characteristics of pathologically proven myofibroblastoma in Koran patients. METHODS: Pathologic reports of patients who underwent surgeries at two centers between April 2003 and March 2016 were retrieved from the electronic medical record system of the hospital. Pathologic reports were included after performing a search using the keyword “myofibroblastoma”. RESULTS: The cohort consisted of 11 subjects and included eight female and three male individuals. The patients' ages ranged from 9 to 66 years. Tumors were located in the vagina in three patients and presented in the breast in seven patients. One case presented with an abdominal mass. The tumors ranged in mean size from 4.0 to 53.0 mm. Despite a relatively long-term follow-up, no case had evidence of tumor recurrence. CONCLUSION: We evaluated the various anatomic locations of pathologically proven myofibroblastoma in Korean patients. As an extremely rare tumor, physicians should pay special attention to differential diagnosis. Surgical resection is the preferred method for a cure, and the recurrence rate is extremely low.
