[A Case of Ectopic Pheochromocytoma between the Abdominal Aorta and Inferior Vena Cava].

We report a case of ectopic pheochromocytoma which is relatively rare. A 50-year-old man was found to have an abdominal tumor on a medical examination, and contrast-enhanced computed tomography showed a retroperitoneal tumor between the abdominal aorta and the inferior vena cava. As a result of close examinations, an ectopic pheochromocytoma was suspected. He was asymptomatic and suspected infiltrating into great vessels, but possibility of a malignant neoplasm could not be ruled out for the tumor had a tendency to enlarge, the resection of the tumor was performed. During the operation, the invasion of the tumor into the great vessels was denied and the tumor was completely resected. Large fluctuation of the blood pressure was not observed during the operation. Histopathological evaluations of the resected specimen revealed the ectopic pheochromocytoma. A pheochromocytoma was newly defined as a tumor with malignant potential for metastasis in all cases by the WHO classification published in 2017. He was diagnosed as moderately malignant by GAPP score, therefore the careful follow-up was considered necessary in the future.

[A Case of Metastatic Breast Cancer with BRCA1 Mutation after Breast Reconstruction and Pregnancy].

We present the case of a 31-year-old woman with a chief complaint of a left breast mass. The patient visited our department for an evaluation of this left breast mass. Left breast cancer(cT1cN0M0, cStage Ⅰ, triple negative type)was diagnosed, and left partial mastectomy and sentinel node biopsy were performed. Although the pStage was the same prior to surgery, a BRCA1 mutation was identified on genetic testing. After administration of postoperative adjuvant chemotherapy (epirubicin, cyclophosphamide, and paclitaxel), consorted mastectomy, tissue expander insertion, and breast reconstruction with silicone implant were performed. Spontaneous pregnancy occurred 1 year and 10 months after the first operation. She had an uneventful delivery with a normal course of labor 2 years and 6 months after the surgery. Two years and 11 months after the first operation, she visited our institution with complaints of headache, dizziness, and difficulty eating. Upon assessment, brain, lung, liver, and bone metastases were identified on contrast-enhanced computed tomography. Concentrated glycerin and fructose, steroid administration, and whole-brain irradiation improved the symptoms due to cerebral edema. Thereafter, olaparib was started, and treatment was continued while maintaining partial response(PR).

[A Case of Laparoscopic Distal Gastrectomy for Gastric Cancer with an Adachi Type â ¥ Group 24 Vascular Anomaly].

We report a case of successful laparoscopic distal gastrectomy for gastric cancer with an Adachi type Ⅵ group 24 vascular anomaly. A male in his 60s exhibited a type 0-Ⅱa plus Ⅱc lesion at the lesser curvature of the gastric angle by esophagogastroduodenoscopy and was diagnosed with tub2. He was referred to us for surgical treatment. The clinical diagnosis was cT1bN0M0, and cStage Ⅰ. Preoperative multidetector-row computed tomography(MDCT)showed an Adachi type Ⅵ group 24 vascular anomaly. At laparoscopic surgery, we dissected No. 8a lymph nodes with exposure of the surface of the portal vein because the common hepatic artery was absent. The left gastric artery and splenic artery formed a common trunk. As there are various kinds of vascular anomalies of the celiac artery branch, we must understand the arterial running pattern prior to gastric surgery. This technique is more useful in laparoscopic surgeries where tactile sensation is limited. To prevent perioperative and postoperative complications, we must recognize the anomaly pattern prior to surgery using MDCT.

[A Case of Laparoscopic Low Anterior Resection and Adrenalectomy for Rectal Cancer and Adrenal Tumor].

A 70-year-old woman had consulted a doctor at a former clinic because of bloody stool and colonoscopy revealed a type 2 tumor of the rectum. She was referred to our hospital for further examinations and treatment. Preoperative blood examination showed an elevated HbA1c level of 10.2%. Abdominal CT showed a 25mm tumor in the left adrenal gland. The patient was diagnosed with adrenal Cushing's syndrome based on low ACTH levels, disappearance of circadian variation in blood cortisol levels, lack of inhibition by dexamethasone loading, and high urinary cortisol levels. Laparoscopic adrenalectomy for left adrenal tumor and low anterior resection for rectal cancer were performed. The pathological findings were rectal cancer, pap, pT1b(SM), pN0, cM0, fStageⅠof rectal cancer, and adrenal cortical adenoma. The postoperative course was uneventful with steroid replacement therapy. The ileal stoma was closed 4 months after surgery. Surgery in hyperadrenalism requires perioperative steroid replacement therapy because of the risk of postoperative acute adrenal failure. In addition, when diabetes is poorly controlled, we should be careful about risk of leakage and susceptibility to infection.

[A Case of Appendiceal Mucinous Adenocarcinoma Detected with a Bladder Tumor].

A 74-year-oldwoman hadconsultedthe department of urology in our hospital because of microscopic hematuria. Cystoscopy revealeda urinary bladder tumor, suspectedas an adenocarcinoma basedon biopsy. MRI showeda cystic tumor of the appendix with vesical fistula; therefore, she underwent an operation with a diagnosis of appendiceal cancer invading the urinary bladder. During the operation, we found that the appendix sunk into the urinary bladder with right adnexa. Therefore, we performed ileocecal resection, partial resection of the urinary bladder, and right adnexectomy. Macroscopically, the bladder was filled with a large number of mucus lumps. A papillary tumor, 4 cm in size, growing in the lumen of the bladder was detectedat the invasion site. Microscopically, proliferating carcinoma cells in a papillary form were observedin the lumen of the appendix with mucus production, invading the wall of the urinary bladder at the fundus of the appendix. Thus, the patient was diagnosed with mucinous adenocarcinoma of the appendix(V, type 1, 45×30 mm, muc, pT4b[SI, urinary bladder], int, INF c, ly0, v0, pN0, cM0, pStage II ). Primary appendiceal cancer invading the urinary bladder is very rare; herein, we report a rare case of appendiceal mucinous adenocarcinoma detected with a bladder tumor and present a literature review.

Successful Treatment of a Case of Necrotizing Fasciitis due to Vibrio vulnificus in a Cold Climate in Japan.

Vibrio vulnificus infection often occurs in warm regions, frequently leading to necrotizing fasciitis, sepsis, and death. We herein report a rare case presenting in a cold climate region in northern Japan, Aomori district, of a V. vulnificus infection complicated by necrotizing fasciitis and septic shock. The patient's prior history of injury and typical clinical course were helpful clues to the diagnosis of V. vulnificus infection, and early initiation of antimicrobial treatment saved his life. V. vulnificus infection should be considered even in cold regions, particularly if patients have risk factors.

Nutrient intake of highly competitive male and female collegiate karate players.

Nutrient intake of 29 male (M Group) and 16 female (F Group) highly competitive collegiate karate players were compared. The results were also compared with the daily energy expenditure (DEE), Japanese recommended dietary allowances (RDAs) or adequate dietary intakes (ADIs). Dietary information was collected using a 3-weekday diet record. Although the M Group showed significantly higher mean %RDAs or %ADIs in iron, vitamin B1, phosphorus, magnesium, and sodium than the F Group, many of the mean %RDAs or %ADIs were below RDAs or ADIs in both groups. The subjects who skipped meals tended to show lower mean %DEE, Japanese %RDAs or %ADIs in minerals and vitamins than the subjects who did not skip in both M and F Groups. The consumption of green and other vegetables and milk and dairy products in both M and F Groups were low. It is concluded that the male and female highly competitive karate players studied in the present study may be at risk of sub-optimal nutrient intake, which increases the potential for nutrient deficiency. The subjects were advised not to skip meals, and to consume a balanced high-carbohydrate, moderate-protein, low-fat diet with increasing green and other vegetables and milk and dairy products to increase mineral, vitamin and dietary fiber intakes.
