Targeted delivery of cytotoxic drugs to tumour tissue has great importance for successful chemotherapy. Legumain is an asparaginyl endopeptidase that is highly up-regulated in a number of solid tumours. The aim of this work was to prepare a novel hyaluronic acid (HA) based legumain sensitive nanogel
BACKGROUND
SMARCA4-deficient thoracic sarcoma is a recently proposed entity of soft tissue tumors associated with an extremely poor prognosis. Its cytologic features have not been well described in the literature yet.
METHODS
A woman in her early 30s who presented with chest pain was found to have a
Three human gastric cancer cell lines, NU-GC-2, NU-GC-3 and NU-GC-4 were established in vitro from the cancer tissues obtained from 3 patients during surgery. The pathological findings of the gastric tumors of these cases revealed poorly differentiated adenocarcinoma (and partial signet-ring cell
Tumor promoters such as phorbol 12-tetradecanoate 13-acetate (TPA), mezerein, teleocidin, aplysiatoxin, and benzoyl peroxide, although structurally unrelated, induce similar, profound changes in morphology in differentiated epithelial Madin-Darby canine kidney (MDCK) cell colonies. The alteration is
Docetaxel is a first-line chemotherapeutic agent for treating advanced breast cancer. The development of chemoresistance or multidrug resistance (MDR), however, results in breast cancer chemotherapy failure. This study aims to explore the molecular mechanisms underlying docetaxel-resistance in
A malignant gastrointestinal neuroectodermal tumor (GNET), a distinctive entity covering the characteristics of clear cell sarcoma (CCS) of gastrointestinal tract described recently, arising primarily in the ileum of a 33-year-old woman is reported. Histologically, the neoplasm involved the full
BACKGROUND
Malignant gastrointestinal neuroectodermal tumor (GNET) is an extremely rare entity that was first described by Zambrano et al. in 2003 as "Clear cell sarcoma-like tumor of the gastrointestinal tract". It shares some of the histological features of clear cell sarcoma (CCS) but lacks the
Malignant gastrointestinal neuroectodermal tumor (GNET), is a rare soft tissue sarcoma. Here we report a case of GNET arising in the intestine of a 33-year-old female, who had been treated for gastric adenocarcinoma with surgery and chemotherapy at the age of 19, in 2001. Since then, she underwent
Malignant gastrointestinal neuroectodermal tumors (GNETs) are rare aggressive malignant neoplasms that exclusively occur within the wall of the gastrointestinal tract. The GNET was first described as an 'osteoclast-rich tumor of the gastrointestinal tract with features resembling clear cell sarcoma
The rare case of a stromal Leydig cell tumor of the ovary occurring in a 21-year-old woman who developed signs of virilization during pregnancy is reported. Serum androgen levels were markedly elevated. At cesarean section, a slightly hypotrophic, but otherwise normal, female infant was delivered
Apocrine hidradenomas (AH) once believed to harbor myoepithelial cells are now considered pure epithelial neoplasms. They are categorized separately from adenomyoepitheliomas which consist of apocrine epithelial and myoepithelial components. Reports of myoepithelial tumors arising in AH have
A sclerosing stromal tumor is a very rare benign sex cord-stromal tumor of the ovary. Because its clinical presentation and imaging findings are similar to those of borderline or malignant epithelial tumors and other sex cord-stromal tumors, accurate preoperative clinical diagnosis can be difficult.
We report a new case of granular cell tumor (GCT) is a benign neoplasm in the esophagus (a rare location of which there are only described 80 cases. The tumor was diagnosed in a man aged 55 by endoscopy (asymptomatic from the esophagus point of view) during a chronic liver disease survey. The
OBJECTIVE
To investigate the clinicopathological characteristics of large cell calcifying Sertoli cell tumor (LCCSCT) of the testis.
METHODS
We studied a case of LCCSCT by light microscopy, Western blotting and immunohistochemistry, reviewed relevant literature, and analyzed the clinical,
Metastases to the breast are uncommon, accounting for 0.5% of breast tumors, and most of them are originated from lymphoma, melanoma and carcinomas of various organs. Alveolar soft part sarcoma (ASPS) is a very rare neoplasm that is usually found in the lower extremities. Lungs are the common site
