Desmoplastic Fibroblastoma (Collagenous Fibroma) of the Knee: A Case Report and Literature Review.

Background/aim: Desmoplastic fibroblastoma, also known as collagenous fibroma, is a rare benign mesenchymal neoplasm that primarily arises in the subcutaneous tissue of upper extremities and limb girdles. The knee is an uncommon location for desmoplastic fibroblastoma. Recent studies have demonstrated the presence of immunoreactivity for FOS like 1 (FOSL1) and rearrangements of FOSL1.

Intramuscular Hybrid Nerve Sheath Tumor of the Thigh: Case Report and Literature Review.

Background/aim: Hybrid nerve sheath tumor (HNST) is a benign peripheral nerve sheath tumor with combined features of more than one histological type, such as schwannoma, neurofibroma, and perineurioma. It remains under-recognized in routine clinical practice. Herein, we describe an unusual case of intramuscular HNST of the thigh.

Giant Cell Tumor of the Acromion: Case Report and Literature Review.

Background/aim: Giant cell tumor of bone (GCTB) is a locally aggressive neoplasm that typically occurs in the ends (epiphyses) of long bones of young adults. Flat bones are uncommon sites of involvement. Herein, we describe an unusual case of pathologically proven GCT of the acromion.

Biology and Management of Deep-seated Atypical Lipomatous Tumor of the Extremities.

Adipocytic neoplasms are frequently encountered in clinical practice. Atypical lipomatous tumor (ALT) is a locally aggressive but non-metastasizing adipocytic neoplasm that primarily occurs in the proximal extremities of middle-aged to older adults. Histologically, ALT is divided into adipocytic (lipoma-like), sclerosing and inflammatory subtypes.

Superficial Angiomyxoma of the Wrist: Case Report and Literature Review.

Background/aim: Superficial angiomyxoma (SAM) is a rare benign soft-tissue tumor that usually occurs in the trunk, head and neck, and lower extremity of middle-aged adults. Herein, we describe an unusual case of SAM of the wrist, which was initially diagnosed as a ganglion cyst on imaging.

Case Report: The patient was a 71-year-old man with no history of trauma who presented with a 2-year history of a palpable mass in the left wrist.

Overexpression of microRNA-5100 decreases the aggressive phenotype of pancreatic cancer cells by targeting PODXL.

Metastasis is the main cause of cancer-associated death, and metastasis of pancreatic cancer remains difficult to treat because of its aggressiveness. MicroRNAs (miRNAs) play crucial roles in the regulation of various human transcripts, and many miRNAs have been reported to correlate with cancer metastasis. We identified an anti-metastatic miRNA, miR-5100, by investigating differences in miRNA profiling between highly metastatic pancreatic cancer cells and their parental cells.

CD146 attenuation in cancer-associated fibroblasts promotes pancreatic cancer progression.

Cancer-associated fibroblasts (CAFs) are heterogeneous cell populations that influence tumor initiation and progression. CD146 is a cell membrane protein whose expression has been implicated in multiple human cancers. CD146 expression is also detected in pancreatic cancer stroma; however, the role it plays in this context remains unclear.

Characteristics and surgical outcome of HCC patients with low platelet count.

Background/aims: Hepatocellular carcinoma (HCC) patients often have low platelet count (LPC). The aim of this study was to determine unique features of HCC patients with LPC.

Methodology: HCC patients who underwent surgery were divided into two groups: LPC group (platelet count ≤100,000/mm³, n=84) and control group (platelet count >100,000/mm³, n=240).
