The localized type of tenosynovial giant cell tumor usually occurs on the palmar side of fingers and toes. Tenosynovial giant cell tumors of the tendon sheath are rarely intra-articular. We report a giant cell tumor of the tendon sheath arising from femoral attachment of the anterior cruciate ligament and its treatment with arthroscopy in a 28-year-old man.

Tumor-associated antigen was found by reacting sera from two patients with giant cell tumor of bone with cells derived from their tumors, using autologous serum as intermediate reactant and fluorescein-conjugated goat anti human IgG as final reactant. Approximately 40% of the plump, spindle-shaped cells that formed the background stroma of these tumors possessed the antigen; however, it was not...

We report a case of giant cell tumor originating from the anterior arc of the rib. The tumor and the surrounding chest wall were completely resected, and the chest wall defect was covered with Marlex mesh. Giant cell tumor of the bone usually originates from the epiphysis of long bones. Even when the tumor occur in ribs, it usually occur in the posterior aspect. However, giant cell tumor should...

We report the case of a 74-year-old female patient diagnosed with a giant cell tumor of the sternum. The clinical and radiological presentation was indicative of a primary tumor of the sternum. The patient underwent complementary tests and surgery. The pathological examination confirmed the diagnosis. Commonly observed in the long bones of the appendicular skeleton, this type of tumor is charac...

intra-abdominal desmoplastic small round cell tumor is a rare entity with a few reports worldwide. this tumor commonly occurs in children and adolescent and occurrence in adult age group is very rare. here, we describe an adult male with symptoms of intestinal obstruction due to abdominal mass, located in splenic flexure. after resection, the diagnosis of intra-abdominal desmoplastic small roun...

MicroRNAs (miRNAs, miRs) are small endogenous non-coding RNAs that regulate the expression of protein-encoding genes at the post-transcriptional level. Several studies have described the role of miRNAs in T-cell acute lymphoblastic leukemia (T-ALL), including tumor suppressor and oncogenic miRNAs. Down-regulation of miRNA expression is a prominent feature of human malignancy. This down-regulati...
