Three fibrous histiocytomas, primary in skin, were studied by light and electron microscopy and by frozen section histochemistry. The term malignant was applied to cutaneous tumors which demonstrated aggressive multinodular local growth, including angioinvasion and/or extension into bone, muscle, and fascia. Metastases were not found. Strongly positive reactions for hydrolytic enzymes, particul...

A 48-year-old man with a solitary fibrous tumor of the pelvic underwent resection, but recurrent tumor was found 4 years later. Recurrent solitary fibrous tumor of the pelvic with malignant progression is rare. Solitary fibrous tumor of the pelvic often has an indolent clinical course, so postoperative surveillance may necessitate long-term follow-up because of the potential adverse biological ...

Malignant fibrous histiocytoma is one of the most common sarcomas that occur in soft tissue, it usually develops in old age individuals and the incidence is similar between the genders. We report here on a case with invasive local recurrence after surgical resection of a malignant fibrous histiocytoma that occurred in the left psoas muscle of a 69-year-old male patient. The patient was first ad...

Malignant Fibrous Histiocytoma (MFH) is the most common soft-tissue sarcoma which predominantly surfaces in the retro-peritoneum and extremity. MFH of lung is a very rare condition. The diagnosis is essentially through histologic examination. However, the invasion of the chest wall or other organs might help establish the malignant nature.We report a case of a 77-year-old man who had been prese...

A malignant solitary fibrous tumor arising from the omentum is extremely rare. To our knowledge, this is the first case of a malignant solitary fibrous omentum tumor coexisting with uterine corpus cancer. A 62-year-old woman presented to our hospital with vaginal discharge. Endometrioid adenocarcinoma was diagnosed by endometrial curettage. In addition, a solid tumor in front of the uterus was ...

BACKGROUND A malignant fibrous histiocytoma is a soft tissue tumor that most commonly occurs in the extremities, but rarely involves the liver. The clinical characteristics and therapeutic experiences of primary hepatic malignant fibrous histiocytoma are still limited. METHODS Two cases of primary hepatic malignant fibrous histiocytoma were analyzed retrospectively, and all the literature con...

Background: Intracranial solitary fibrous tumor was rare. However, most intracranial solitary fibrous tumors are benign, cerebral solitary fibrous tumor with malignant transformation was even more unusual. Case present: Herein, we presented a 55 year-old-male who was diagnosed intracranial solitary fibrous tumor five years ago. Partial tumor excision was performed via the pterional craniotomy. ...

INTRODUCTION Malignant fibrous histiocytoma is a very common subtype of soft-tissue sarcoma in middle and late adulthood. However, malignant fibrous histiocytoma of the testis is very rare in adolescents. CASE PRESENTATION We report here the case of a 14-year-old Han Chinese boy, who presented with left scrotal mass lasting for 20 days along with distending pain for 5 days. A physical examina...

OBJECTIVE In this study, 22 cases of locally recurrent urological malignant fibrous histiocytoma were reviewed considering therapeutic options, follow-up and prognosis. PATIENTS AND METHODS In the available literature on this topic we identified 19 cases of locally recurrent genitourinary malignant fibrous histiocytoma. Three additional cases are discussed, primarily arising from the kidney, ...

This report concerns a case of primary de-novo origin malignant fibrous histiocytoma of breast in a 32 years young lady involving almost the entire right breast. Fine needle aspiration cytology of the breast mass suggested a malignant spindle cell lesion. Then she was treated by simple mastectomy followed by chest wall irradiation. Histopathology together with immunohistochemistry confirmed the...
