Inflammatory myfibroblastic tumor (IMT), also known as inflammatory pseudotumor is unusual, benign solid tumor. This tumor is commonly reported in the lungs but can be present in extrapulmonary sites as well. We present the case of a 7-year-old girl with IMT in an unusual location. The patient was admitted with abdominal pain, and ultrasound showed a solid mass in the abdomen. She was operated ...

CONTEXT We report the imaging features of pancreatic schwannomas, a rare benign type of pancreatic tumor. CASE REPORT A 66-year-old woman was admitted to our hospital with a pancreatic tumor indicated in medical examinations. Computed tomography (CT), magnetic resonance imaging (MRI) and endoscopic ultrasonography (EUS) revealed a solid and cystic tumor, 3 cm in diameter, within the body of t...

BACKGROUND Solid pseudopapillary tumor of the pancreas (Frantz tumor) is a rare, low-grade malignant neoplasm. Laparoscopic pancreatoduodenectomy is a good approach for tumors located in the pancreatic head. We present two successful cases in young women. CASE REPORT A 19-year-old woman was admitted to Department of Digestive Surgery due to epigastric pain, nausea, and vomiting. Computed tomogr...

Solid tumors are characterized by an abnormal stroma that contributes to the development of biomechanical abnormalities in the tumor microenvironment. In particular, these abnormalities include an increase in matrix stiffness and an accumulation of solid stress in the tumor interior. So far, it is not clearly defined whether matrix stiffness and solid stress are strongly related to each other o...

Nevoid melanoma is a rare tumor with the origin in melanin-producing cells called melanocytes. The main particularity of this is
 resemblance benign tumor, compound intradermal nevi, despite malignant behavior and aggressivity. On usual stain, we generally observe tumoral proliferation solid architecture, organized nests. cytological atypia observed high power fields; pagetoid migration co...

Tumor lysis syndrome (TLS) is a potentially life-threating complication of tumors or chemotherapy treatment. TLS commonly occurs in hematological malignancies, but it is very rare in patients with a solid tumor. In cases of solid tumors, TLS usually occurs spontaneously and after the initiation of anticancer therapy, and it has a high mortality rate. We present the novel case of a 62-year-old w...

CONTEXT Solid pseudopapillary tumor of the pancreas is a rare neoplasm, predominantly observed in young women and with greatest incidence in the second and third decade. Although large at the time of diagnosis, it has clinically good behavior. The occurrence of infiltrating varieties of solid pseudopapillary tumors is very rare. CASE REPORT We report the case of a 48-year-old man with a giant...

Kaposi's sarcoma-associated herpesvirus is the causative agent of primary effusion lymphoma (PEL), which arises preferentially in the setting of infection with human immunodeficiency virus (HIV). Even with standard cytotoxic chemotherapy, PEL continues to cause high mortality rates, requiring the development of novel therapeutic strategies. PEL xenograft models employing immunodeficient mice ha...

Recent strategies for the treatment of cancer, other than just tumor cell killing have been under intensive development, such as anti-angiogenic therapeutic approach. Angiogenesis inhibition is an important strategy for the treatment of solid tumors, which basically depends on cutting off the blood supply to tumor micro-regions, resulting in pan-hypoxia and pan-necrosis within solid tumor tissu...

•Tumor lysis syndrome is rare in solid tumors.•Tumor lysis syndrome is an oncologic emergency.•We present two cases of spontaneous tumor lysis syndrome arising in uterine cancer.
