We describe an interesting single case of TBL managed by a combined multimodal approach with a review of the literature. Case Report: A patient aged 69-year-old male, newly hypertensive, who presented with a twelve-month history of right testis progressive painful scrotal swelling, which worsens following a motorbike accident. Clinical examination revealed a large tender mass in an erythematous right scrotal bursa. A scrotal ultrasound showed a right heterogenous intra-testicular mass. The patient underwent unilateral (right) radical orchiectomy. Histopathological examination revealed presence of monomorphic lymphoid cells, with moderate to increased size, dissociated inconstantly by macrophages consistent with a Burkitt’s-like non-Hodgkin Lymphoma. After surgery, the patient was transferred to oncologist for adjuvant chemotherapy. Conclusion: A testicular mass is a usual circumstance for the discovery of a primary tumour of the testicle. Burkitt’s testicular lymphoma is a rare tumour whose diagnosis is based on histological findings. There are non-consensual etiological or predisposing factors. The treatment depends imperatively on the stage of the disease. Therapeutic modalities relay on in surgical excision, chemotherapy and radiation therapy but the accurate procedures are not standardized.展开更多

The effects of deguelin on the growth of Raji cells were studied by 3-（4, 5-dimethyl-2-thiazolyl）-2,5-diphenyl-2H-tetrazolium （MTT） assay. Apoptosis was detected through Hoechst 33258 staining. The effect of deguelin on the cell cycle of Raji cells was studied by a propidium iodide method. The expression levels of cyclin D1, P21 and pRb were examined by using Western blotting. The results showed that the proliferation of Raji cells was inhibited in the de guelin-treated group, with a 24-h IC5o value of 21.61 nmol/L and a 36-h IC50 value of 17.07 nmol/L. Proliferation in Raji cells was inhibited significantly by deguelin, while little change was observed in PBMCs. Deguelin induced G2/M arrest in Raji cells. The expression of cyclin D1, P21 and pRb was dramatically down-regulated by deguelin in a dose-dependent manner. It was concluded that deguelin could inhibit the proliferation of Raji cells by arresting the cells at GE/M phase and inducing the cell apoptosis. Moreover, deguelin selectively induced apoptosis of Raji cells with low toxicity to PBMCs. The antitumor effects of deguelin were related to the down-regulated expression of cyclin D1, P21 and pRb proteins.展开更多

The effects of TSA on the growth of Daudi cells were studied by 3-（4, 5-dimethyl-2-thiazolyl）-2,5-diphenyl-2H-tetrazolium （MTT） assay. The effect of TSA on the cell cycle of Daudi cells was assayed by a propidium iodide method. Immunochemistry and Western blot were used to detect the expression of hGCN5. The proliferation of Daudi cells was decreased in TSA-treated group with a 24 h IC50 value of 415.3979 μg/L. TSA induced apoptosis of Daudi cells in a timeand dose-dependent manner. Treatment with TSA （200 and 400 μg/L） for 24 h, the apoptosis rates of Daudi cells were （14.74±2.04） % and （17.63±1.25） %, respectively. The cell cycle was arrested in G0/G1 phase （50, 100 μg/L） and in G2/M phase （200 μg/L） by treatment with TSA for 24 h. The expression of hGCN5 protein in Daudi cells was increased in 24 h TSA-treated group by immunochemistry and Western blot （P〈0.05）. It was suggested that TSA as HDACIs could increase the expression of hGCN5 in Daudi cells, and might play an important role in regulating the proliferation and apoptosis of B-NHL cell line Daudi cells.展开更多

A six years old boy was admitted to our emergency department with complaint of colicky abdominal pain and bilious vomiting for the last month. He was operated due to 3 cm intussusception at ileocecal part. A mass which is about 6 cm in diameter, hard, partly mobile and invaginate the intestine at its posterior aspect was found. Pathology was reported as Burkitt lymphoma. He received two cycles of chemotherapy at post-operative period. He is still event free for the last two years. One must remember that lymphoma can be the lead point in intussusception especially in elderly children.展开更多
