Retroperitoneal desmoplastic small round cell tumor:Pediatric patient treated with multimodal therapy

World Journal of Gastroenterology 2009年第33期15卷 4212-4214页

作者： Yong Seok Kim Seong Jae Cha Yoo Shin Choi Beom Gyu Kim Sung Jun Park in taik chang Department of Surgery College of MedicineChung-Ang University

A desmoplastic small round cell tumor (DSRCT) is a rare, aggressive mesenchymal neoplasm. Although a DSRCT can develop at various sites, the intraabdominal site is the most common location. These tumors are found most commonly among young adolescents and the prognosis is extremely poor. Multimodal treatment with surgery, chemotherapy and radiotherapy is very important for these rare cases, and this treatment can improve patient survival. In this report, we describe the case of an 8-year-old boy diagnosed with DSRCT located in the retroperitoneal space. The patient has undergone surgical resection and adjuvant chemoradiation therapy, and is currently alive without disease recurrence.

Transanal excision of a malignant fibrous histiocytoma of anal canal:A case report and literature review

Malignant fibrous histiocytoma, which is composed of spindle-shaped cells arranged in a pleomorphic and storiform pattern, is rarely found in the colorectum. Although complete surgical excision remains the main stem of therapy, an optimal treatment strategy according to the stage has not been elucidated. We report a case of a 63-year-old woman with an ulcerative lesion in the anorectal junction and a final diagnosis of malignant fibrous histiocytoma. We introduced an access for transanal local excision and adjuvant radiotherapy because the patient refused abdominoperineal resection. No local recurrences or distant metastases were observed 15 mo after the operation. To our knowledge, this is the first case reported in the English literature of a malignant fibrous histiocytoma treated with the transana local excision and adjuvant radiotherapy. This report showed that this approach is selectively reserved for early-stage malignant fibrous histiocytoma and for those patients who refuse radical surgery because of the risk in a permanent colostomy.

Intrauterine midgut volvulus without malrotation:Diagnosis from the 'coffee bean sign'

引用

World Journal of Gastroenterology 2008年第9期14卷 1456-1458页

作者： Jun Seok Park Seong Jae Cha Beom Gyu Kim Yong Seok Kim Yoo Shin Choi in taik chang Gwang Jun Kim Woo Seok Lee Gi Hyeon Kim Department of Surgery College of MedicineChung-Ang University Seoul 156-755Korea Department of Obstetrics and Gynecology College of Medicine Chung-Ang UniversityKorea Department of Radiology College of Medicine Chung-Ang University Seoul 156-755Korea

Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a 'coffee bean sign'. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention.

Locally recurrent penile apocrine carcinoma initially diagnosed as metastatic adenocarcinoma of colon

引用

Chinese Journal of Cancer Research 2013年第6期25卷 777-780页

Apocrine carcinoma is a rare malignant adnexal neoplasm. The differential diagnosis between apocrine carcinoma and cutaneous metastasis is often difficult. Here, we report a case of locally recurrent penile apocrine carcinoma initially diagnosed as metastatic adenocarcinoma of the colon. A 75-year-old man with a history of surgical resection due to sigmoid colon cancer and penile metastasis two years prior to this study presented with a nodule at the left penile base. He underwent a wide local resection of the penile mass under a suggested preoperative diagnosis of extra-mammary Paget＇s disease （EMPD） associated with previous sigmoid colon cancer. However, the previously and currently resected penile masses were identified as primary apocrine carcinoma upon hematoxylin and eosin （H＆E） staining and immunohistochemical staining. Although the incidence is extremely rare, both clinicians and pathologists should be alert to the possibility of synchronous double primary apocrine carcinoma in cancer patients with malignant cutaneous lesions.

为提高微细凹版胶印中油墨转移率,对两分离平行版之间的液体转移过程进行了实验研究。一版固定,另一版垂直移动,附着于版上的液滴被一分为二。因为两液滴的容积比随接触角而变化,所以在本研究中需特别关注两版上液滴的表面接触角。改变表面接触角的方法有化学处理、等离子体表面改性和介质电润湿等,通过图像分析可观测表面接触角和测量液滴体积。同时研究了液体转移过程及其相关现象,如液滴与平行版接触区域内卫星式液滴的产生及变化。实验结果有助于确定微细凹版胶印中印版滚筒、橡皮滚筒及基材的最佳表面能。
