Retrospective investigation was performed on 16 patients with lymphoid tumor in mesentery operated in Viet Duc Hospital from 1991 to 2001. Diagnosis signs of clinical value included: abdominal pain (93%), loss of body weight (56,2%), tumor palpable in abdomen (75%), mobile tumor (58,33%). 12/16 patients undergo an ultrasonic examination and in 4/12 ganglion tumor, 2/12-mesenterial tumor, 6/12 undefined tumor in the abdomen were detected. The operation must be considered to solve the complications (11/16 patients) and determine the phase of disease. Once the result of pathological anatomy is concluded, a post-operation chemiotherapy must be realized systematically

Nodular lymphoid hyperplasia is a reaction of the intestinal lymphatic tissue to specific inflammatory stimuli and may be probably of no clinical significance, but it may evolve to primary gastrointestinal lymphoma in more severe cases. Recently, several cases of nodular lymphoid hyperplasia complicated by primary gastrointestinal lymphoma have been reported, and which suggested that nodular lymphoid hyperplasia could not be considered as simple benign colon disease any more. We also experienced a case of primary jejunal malignant lymphoma associated with nodular lymphoid hyperplasia, and report this case with a brief review of relevant literatures.

We report herein on a case of primary mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland in a 57-year-old woman with coexisting Hashimoto's thyroiditis, and we include its characteristic imaging, histopathologic and immunohistochemical findings.

Malignant lymphoma involving the testis is a rare disease with poor prognosis and the most common type of testicular malignancy after 60 years of age. But the origin of this tumor is controversial in an organ supposedly devoid of lymphoid tissue, so it is difficult classifying testicular involving as primary or secondary without prolonged observation of the patient. We report a case of malignant lymphoma of the testis developed in a 56 years old man and the relevant literature has been reviewed.

Based on a review of the literature, this paper provides an update on surgical treatment of middle and low rectal cancer and discusses issues of debate surrounding that treatment. The main goal of the surgical treatment of rectal cancer is radical resection of the tumor and surrounding lymphatic tissue. Local excision of early rectal cancer can be another treatment option, in which the patient can avoid possible complications related to radical surgery. Neoadjuvant chemoradiation therapy (CRT) has been recommended for patients with cT3-4N0 or any T N+ rectal cancer because CRT shows better local control and less toxicity than adjuvant CRT. However, recent clinical trials showed promising results for local excision after neoadjuvant CRT in selected patients with low rectal cancer. In addition, the "wait and see" concept is another modality that has been reported for the management of tumors that show complete clinical remission after neoadjuvant CRT. Although radical surgery for middle and low rectal cancer is the cornerstone therapy, an ultralow anterior resection with or without intersphincteric resection (ISR) has become an alternative standard surgical method for selected patients. Many studies have reported on the oncological safety of the ISR, but few of them have addressed the issue the functional outcome. Furthermore, an abdominoperineal resection (APR) has problems with high rates of tumor perforations and positive circumferential resection margins, and those factors have contributed to its having a high rate of local recurrence and a poor survival rate for rectal cancer compared with sphincter-saving procedures. Recently, great efforts have been made to reduce these problems, and the total levator excision or the extended APR concept has emerged. Surgical management for low rectal cancer should aim to radically excise the tumor and to preserve as much of the sphincter function as possible by using multidisciplinary approaches. However, further prospective clinical trials are needed for tailored treatment of rectal cancer patients.

Lymphoepithelial cyst of the pancreas is a rare benign cystic tumor which is histologically characterized by cyst containing keratin, lined by mature squamous epithelium surrounded by lymphoid tissue, often with prominent follicles. Cystic lesions of the pancreas are more often detected because sensitive abdominal imaging tests are used for multiple indications, but preoperative differential diagnosis is difficult despite the advancements of imaging technologies. We herein report a case of lymphoepithelial cyst incidentally found on routine abdominal ultrasonography which showed characteristic findings on endoscopic ultrasonography preoperatively and discuss the radiologic features of lymphoepithelial cyst.

The etiology of the primary (congenital) lymphedema is as an unknown abnormal development of the subcutaneous lymphatic tissue itself. Lymphedema is expressed at different ages, and may be sporadic or inherited. Congenital lymphedema are rarely isolated to the external genitalia, but rather have lower extremity involvement. Isolated congenital lymphedema of the external genitalia is also extremely rare; to our knowledge, there has been no case report in the Korean literature. Our experienced case was that of a 17 year old male patient, who was treated surgically (scrotal reconstruction), with a relatively good result.
