Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths. Protoporphyrin IX (PPIX) has been used for photodynamic therapy. Mesenchymal cancer cells adapt to tumor microenvironments for growth and metastasis possibly in association with miRNA dysregulation. In view of the effect of PPIX on cancer-related genes, and its potential to inhibit tumor growth and migration/invasion, t...

 Abstract Liver neoplasm is not an uncommon disease in Asian countries. Liposarcoma is a rare mesenchymal malignant tumor which usually originates in the retroperitoneum and extremities. From 1973 till now about 10 cases of primary liver liposarcoma have been reported. We present the eleventh case in a young adult female with uncommon presentation. She suffered from a huge mass in the right por...

Gastric liposarcoma is very rare such that only a few cases have been reported to date. We present a case of a 62 - year - old diabetic man who presented with epigastric pain, vomiting, constipation and melena. The physical examination was unremarkable. By computed tomography (CT), a large mass with low attenuation value was seen in the left abdominal cavity. Histologic examination of a ga...

Gastrointestinal Stromal Tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract and most commonly affects the stomach, while fibromatosis is a rare locally aggressive fibrous tissue neoplasm. There have been reports of GIST and fibromatosis occurring in same individual and in most of them fibromatosis occurs within the abdomen. In 75% of patients fibromatosis occurs aft...

UNLABELLED Solid tumors are generally composed of two major components: heterogeneous malignant cells and non-malignant stromal part. The latter comprises several types of non-malignant cells of mesenchymal, endothelial and immune origin and together with the extracellular matrix significantly affects the biological properties of the tumor. This minireview is focused on recent advances in the u...

introduction: malignant mesenchymal tumors of the larynx are rare. one type of malignant mesenchymal tumor is synovial sarcoma with unknown histogenesis, which occurs predominantly in the lower extremities of young adults. the head and neck region is a relatively rare location. there are few cases of malignant mesenchymal tumors with laryngeal localization in literature.  case report: in this r...

primary rhabdomyosarcoma (rms) of the kidney is a rare malignant mesenchymal tumor with an aggressive clinical course. adult renal rms is typically a pleomorphic histologic subtype and only a few cases have ever been reported. we herein present a new case of renal rms of the embryonal histologic subtype in a 26-year-old woman.
