CONTEXT Solid pseudopapillary tumor of the pancreas is a rare neoplasm which affects young women. On the other hand, pancreas divisum is an anomaly which develops at 7 weeks of gestation. Here, we report a case of a solid pseudopapillary tumor of the pancreas with concomitant pancreas divisum. CASE REPORT A 26-year-old woman was diagnosed as having a pancreatic tumor with solid and cystic com...
BACKGROUND Its considerable size at the time of diagnosis and low grade of malignancy are typical features of the solid-pseudopapillary tumor, which has a tendency to predominantly affect young females. A relationship to the long-term intake of oral contraceptives is discussed. Invasive tumor growth or metastases have been observed only rarely until now. METHODS The 53-yr-old female patient w...
Evolutionary mechanisms in cancer progression give tumors their individuality. Cancer evolution is different from organismal evolution, however, and we discuss where concepts from evolutionary genetics are useful or limited in facilitating an understanding of cancer. Based on these concepts we construct and apply the simplest plausible model of tumor growth and progression. Simulations using th...
pleuropulmonary blastoma [ppb] is a very rare, highly aggressive and malignant tumor that originates from either the lungs or pleura. it occurs mainly in children aged less than five or six years. it has poor prognosis with three different subtypes: cystic [type i], combined cystic and solid [type ii] and solid [type iii]. ppb is treated with aggressive multimodal therapies including surgery an...
The objective of this study is to investigate the anti-tumor effect of Ginkgo biloba exocarp extracts (GBEE) on B16 melanoma bearing mice and its related molecular mechanisms. The B16-F10 melanoma solid tumor model was established in C57BL/6J mice. The tumor-bearing mice were treated with GBEE (50, 100, 200 mg/kg), taking cis-Dichlorodiamineplatinum (Ⅱ) (DDP, 3 mg/kg) as pos...
We report on a 13-year-old girl with a solid cystic tumor of the pancreas. She was referred to our hospital with abdominal pain in the left upper quadrant. Physical examination revealed a firm mass in the abdomen. Ultrasonography showed a clearly demarcated round mass with a mixture of solid and cystic components. Computed tomography confirmed that the mass measured 5 x 5 cm with low density in...
Recently, the US Food and Drug Administration (FDA) approved the first chimeric antigen receptor T cell (CAR-T) therapy for the treatment CD19-positive B cell acute lymphoblastic leukemia. While CAR-T has achieved remarkable success in the treatment of hematopoietic malignancies, whether it can benefit solid tumor patients to the same extent is still uncertain. Even though hundreds of clinical ...
Nanocarrier-based anti-tumor drugs hold great promise for reducing side effects and improving tumor-site drug retention in the treatment of solid tumors. However, therapeutic outcomes are still limited, primarily due to a lack of drug penetration within most tumor tissues. Herein, we propose a strategy using a nanocarrier-based combination of vascular disrupting agents (VDAs) and cytotoxic drug...
Castleman’s disease, giant lymph node hyperplasia, is a kind of benign lymphoproliferative disease with gentle behavior. Its etiology and prevalence are unclear. This rare disease is usually found in mediastinal area asymptomatically and incidentally. It is also rare to see this tumor in the retroperitoneum. In this study, we have introduced a 34-year-old woman who referred just with occasional...
when considering a patient with dysphagia, an attempt should be made to determine whether the patient has difficulty only with solid boluses (suggestive of mechanical dysphagia) or with liquids and solids (suggestive of a motility dysphagia). lesions such as an oesophageal tumor and external pressure effect from a lung tumor or aberrant vessel can lead to mechanical dysphagia. endoscopy and / o...
