Abstract Synovial sarcomas are rare malignant mesenchymal soft tissue tumors. We presented the case of a 53-year-old woman patient presenting with acute deep vein thrombosis, later diagnosed as synovial sarcoma femoral wall. The tumor was identified through cross-sectional magnetic resonance angiography and computed tomography, followed by ultrasound-guided core biopsy. report emphasized import...

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...

 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...

RATIONALE Solitary fibrous tumor (SFT) is a rare benign soft tissue mesenchymal neoplasm. There have been a few reports of extrapleural SFTs although it can occur anywhere in the body. PATIENT CONCERNS A 30-year-old male presented with an anterior neck mass since one month. DIAGNOSES Based on physical and radiologic examination, preliminary differential diagnosis was thymic neoplasm or intr...

A case is reported of a primary rhabdomyosarcoma occurring in the right subfrontal region of a 16 year old girl. The patient suffered from dull frontal headache and proptosis for three months before hospitalization. The circumscribed and demarcated neoplasm involved the dura mater, and invaded the frontal sinus and roof of the orbit on the same side. The pathogenesis of the tumour is thought to...

The light microscopic, immunohistological and ultrastructural findings in two cases of malignant fibrous histiocytoma arising in salivary glands are presented and the features of seven previously reported cases are reviewed. This neoplasm is extremely rare in this site and may pose problems in diagnosis. It has to be distinguished from other spindled cell tumours, in particular from epithelial ...

Malignant fibrous histiocytoma (MFH) can occur as a rare mesenchymal neoplasm of the deep structures of the head and neck region. An unusual case of MFH of the tongue is described in a 61-year-old male. The primary tumour measured 90 X 50 X 30 mm. Treatment consisted of hemiglossectomy in continuity with a supra-omohyoidal neck dissection. The patient has been free from disease for 2 years. The...

BACKGROUNDS Angiomyofibroblastoma (AMFB) is a rare histopathologic finding of the female lower genital tract. This tumor belongs to the group of mesenchymal tumors. Mesenchymal neoplasms of the modified genital skin and mucosa are uncommon. The majority of these lesions are seen in females and, collectively, they form a family of vulvovaginal soft tissue tumors. This family includes fibroepithe...

Rhabdomyosarcoma (RMS) is a high-grade, malignant mesenchymal neoplasm. These tumors represent the most common soft tissue sarcomas of children and adolescents. RMS is uncommon on the lip and it is rarely seen in adults. Here, we report a rare case of primary RMS, embryonal type, occurring on the upper lip in a 27-year-old female.

Aggressive angiomyxoma is a locally mesenchymal, benign, and rare neoplasm. The vulva, perineum, and pelvis are the most common sites of involvement. The preoperative diagnosis is postulated by CT, sonography, MR image and angiography. The immunohistochemical study reveals the definitive diagnosis. The therapy is only surgical, and because of its tendency to recur locally, the excision has to b...
