Pelvic malakoplakia presenting as endometrial cancer: a case report

Malakoplakia is a rare granulomatous, inflammatory disease generally manifesting as ulcers of the urogenital tract, especially in the bladder, but it can occur in any part of the body. Because of its varied clinical presentations, malakoplakia is considered for differential diagnosis upon suspicion. The final diagnosis is confirmed by the presence of Michaelis-Gutmann bodies. We report a case of pelvic malakoplakia accompanied by left lower quadrant pain that was misdiagnosed as endometrial cancer with pelvic mass based on imaging studies. The patient underwent dilatation and curettage, and the pathology report revealed no malignancy. Because of persistent pain and septic shock, she underwent a debulking operation to remove the mass. Histopathologic examination revealed malakoplakia. For postoperative management, she received broad-spectrum antibiotics, but abdominal pelvic computerized tomography performed on postoperative day 9 revealed pelvic mass recurrence. To the best of our knowledge, this is the only rare case report of pelvic malakoplakia mimicking endometrial cancer.

A case of anaphylactoid reaction to nonionic contrast agent, Iodixanol (Visipaque(R)) during coronary angiography / 대한내과학회지

Radiocontrast agent infusion is the most common cause of non-IgE mediated anaphylactoid reaction in the modern medical procedures. The newer lower-osmolar nonionic contrast agents cause significantly lower adverse reactions than the high-osmolar ones. However, anaphylactoid reaction to nonionic contrast agent can cause life-threatening events and even death has been rarely reported. Iodixanol (Visipaque(R)) is a nonionic, dimeric contrast agent, which is currently used in cardiac catheterization. Here we report a case of anaphylactoid reaction to Iodixanol, a nonionic radiocontrast agent, during cardiac catheterization. A 45-year-old male patient underwent cardiac catheterization for evaluation of substernal pain during exercise. Five minutes after this contrast injection to the left coronary artery, he complained itching and dizziness. Subsequently, generalized urticaria, cyanosis and hypotension were developed. His coronary angiogram showed normal findings. He was treated with intravenous fluids, intravenous diphenhydramine, sucutaneous epinephrine and sympathomimetics and one hour later he recovered. This case suggests that anaphylactoid reaction to a radiocontrast media, iodixanol, should be considered in the list of differential diagnoses for cardiopulmonary arrest during cardiac catheterization.

A Case of Amoxicillin-induced Segmental Hemorrhagic Colitis / 대한소화기내시경학회지

Clinically, we often encounter patients who have symptoms of loose stool or diarrhea due to the use of antibiotics. Psuedomembranous colitis is the most frequent, but hemorrhagic colitis is rare. Penicillin-like-antibiotics-induced hemorrhagic colitis was infrequently reported in abroad, but in Korea, quinolone-induced colitis was reported. We found a case that the patient had the hematochezia after use of amoxicillin for eradication of H. pylori. Colonoscopic abnormalities showed superficial ulceration and mucosal edematous change without pseudomembrane on the ascending and transverse colon. We diagnosed the amoxicillin-induced hemorrhagic colitis by clinical course, colonoscopic findings, histologic findings and other laboratory results for differential diagnosis. This disease is rare but rapidly recovered after the withdrawal of the antibiotics and has a good prognosis. Therefore, we should differentiate this disease from hemorrhagic colitis of other causes by history taking.

A Case of Cushing's Syndrome Complicating Pregnancy Adrenalectomized after Delivery / 대한내분비학회지

Pregnancy is rare in women with Cushing's syndrome, as the associated infertility is related to excess cortisol and/or androgen. However, approximately 100 such cases have been reported, with 50% due to an adrenal cortical adenoma. Establishing a diagnosis and cause can be difficult. Clinically, striae, hypertension and gestational diabetes are common features in pregnancy, with hypertension and diabetes being the most common signs of Cushing's syndrome in pregnant women. Furthermore, biochemically, a normal pregnancy is associated with a several fold increase in plasma cortisol, as the increased cortisol production rate also increases the cortisol binding protein. Untreated, the condition results in high maternal and fetal morbidity and mortality. An adrenal or pituitary adenoma should be excised, but a metyrapone, which is not teratogenic, has been effective in controlling many cases of excess cortisol. Here, a case of Cushing's syndrome, complicating a pregnancy due to an adrenal cortical adenoma, with thorough obstetric and medical management, including a metyrapone, which was adrenalectomized after delivery, is reported.
