    We encountered a very rare case of fulminant necrotizing enterocolitis (F-NEC) in a preterm male baby. The course of NEC and sepsis in this case was clearly different from the usual course. After onset at 14 days of life, catheter-related bloodstream infection was first assumed, and antibiotics and γ-globulin administration were started. However, 12 hours after onset, the baby’s abdominal distension increased remarkably, and his entire abdominal wall turned red to purple. Escherichia coli were isolated from the blood culture, but the catheter tip culture was negative. Exchange transfusion was performed 32 hours after onset, but no significant changes were observed in the baby’s general condition, and he died 46 hours after onset. The acute phase reactants of CRP and α1-acid glycoprotein increased, but haptoglobin did not. Although IL-1β and TNFα increased as expected with sepsis, IL-6, IL-8, IL-10, and G-CSF however increased to a greater extent than expected. From the above, we diagnosed the development of intestinal necrosis as a result of widespread intestinal ischemia, and that sepsis was associated with this poor condition.

    Struma ovarii is a rare taratoma that accounts for 0.5-1% of all ovarian tumors. It is sometimes difficult to differentiate struma ovarii from ovarian carcinoma. We encountered a case of struma ovarii that was suspected to be malignant due to the accumulation of massive ascites and an elevated CA125 level. It was successfully treated with laparoscopic surgery.

    A 37-year-old nulliparous woman consulted a local physician with a chief complaint of abdominal distention. Computed tomography (CT) of the abdomen revealed a pelvic tumor with a large amount of ascites. She was referred to our department. Contrast-enhanced magnetic resonance imaging (MRI) and CT showed bilateral ovarian tumors with multicystic and solid components. CA125 level was markedly elevated. Two cytological examinations of ascites showed no malignant cells. Preoperatively, malignancy was strongly suspected, but considering the possibility of a benign ovarian tumor, laparoscopic surgery was scheduled. During laparoscopic surgery, 4,850 mL of ascites were aspirated, and the left adnexa was removed. Intraoperative rapid pathology suggested struma ovarii with no evidence of malignancy. Postoperative pathology showed mature teratoma and struma ovarii.

    Although struma ovarii is benign in 90-95% of cases, there have been scattered case reports in which suspected malignancy led to unnecessary or excessive surgery. We propose that appropriate preoperative imaging and accurate intraoperative rapid pathology can prevent excessive surgery, conservative or laparoscopic excisions should be considered.
