Bioimaging and therapeutic agents accumulated in ectopic tumors following intravenous administration of hybrid nanocrystals to tumor-bearing mice. Solid, nanosized paclitaxel crystals physically incorporated fluorescent molecules throughout the crystal lattice and retained fluorescent properties in the solid state. Hybrid nanocrystals were significantly localized in solid tumors and remained in...

Introduction: Solid pseudopapillary tumor is a rare entity considered to be a tumor of low malignant potential and therefore proper evaluation and diagnosis is important. Case Series: We report two cases of solid pseudopapillary tumor with special emphasis on cytomorphology, histopathology and immunohistochemistry. Preoperative image guided cytopathology is helpful for correct identification of...

Ovarian fibroma is the commonest benign tumor of the ovarian stroma. The cellular subtype accounts for around 10% of ovarian fibromatous tumors. The cellular fibroma is a tumor of uncertain malignant potential that may recur or be associated with peritoneal implants. Usually these are solid tumors, sometimes with small areas of cystic degeneration. This case is reported to highlight an unusual ...

CONTEXT Solid-pseudopapillary tumor of the pancreas is a rare tumor which usually affects young females in their second and third decade of life. Metastasis is very rare after a resection of curative intent. CASE REPORT We report a case of a 65-year-old white female who presented with metastasis to the liver four years after Whipple's resection for a solid-pseudopapillary tumor of the pancrea...

Solid pseudopapillary tumor of the pancreas is a rare pancreatic tumor that predominantly occurs in young non-Caucasian women. Although most tumors show benign behavior, malignant degeneration may occur. A case of solid pseudopapillary pancreatic tumor in a Caucasian woman is presented that was investigated by endoscopic ultrasonography (EUS), computed tomography, magnetic resonance imaging and...

Solid-pseudopapillary tumor of the pancreas constitutes a very rare benign or low-grade malignant lesion occurring most commonly in young women and girls. It was first described by Frantz. Local infiltration, distant metastasis and recurrence are very rare. Until today, the histogenetic origin of the tumor cell remains to be elucidated. In 1996, solid-pseudopapillary tumor of the pancreas was i...

BACKGROUND Solid pancreatic tumors such as pancreatic ductal adenocarcinoma (PDAC), solid pseudopapillary tumor (SPT), and pancreatic endocrine tumor (PET) may occasionally manifest as cystic lesions. In this study, we have put together our accumulated experience with cystic manifestations of various solid tumors of the pancreas. METHODS From 2000 to 2006, 376 patients with pancreatic solid t...

Chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. It is more common in older age and often affects the axial skeleton. We report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. A 40 yr woman presented with decreasing visual acuity and headache. Magnetic resonance (MR) image revealed a cystic sellar and suprasellar...

BACKGROUND Typical aneurysmal bone cysts (ABCs) are osteolytic, multicystic lesions with parietal sclerosis and blood-filled cysts. In rare instances, the cystic components may be completely absent. Such solid variants in ABC (s-ABC) exhibit a solid architecture; making the clinical, radiological, and histological differentiation from other solid bone tumors like osteosarcoma (especially giant ...

To evaluate the in vivo antitumor activity of cleistanthin B in Ehrlich's ascites carcinoma (EAC) and Dalton's ascites lymphoma (DAL) cell lines induced malignant ascites mouse models and DAL cell line induced solid tumor mouse model. All animals were injected with 2 × 106 EAC/DAL cells i.p./s.c. to induce malignant ascites and solid tumor and treated with 5-fluorouracil (5-FU) 20 mg/kg or clei...
