Solitary fibrous tumors (SFTs), are a group of rare, spindle-cell derived fibrous neoplasms most commonly found in the thoracic (pleural) cavity (80%). However, it has been described that SFTs can affect a wide range of anatomic sites outside the pleura, including retroperitoneum, meningeal, nasal cavity and others (20%). Solitary fibrous tumors are usually described in patients between 40 and ...

Multiple adenomatous colon polyps. An adenomatous polyp is an area where the normal cells that line the inside of the colon and begin to make mucous and form a mass on the inside of the intestinal tract. Benign (noncancerous) tumors, including: sebaceous cysts (closed sac filled with liquid found under the skin) epidermoid cysts (lumps in or under the skin often filled with liquid) fibromas (fi...

PURPOSE To correlate fundus autofluorescence (FAF) patterns in choroidal melanocytic lesions with changes present on the surface of such lesions, including lipofuscin, hyperpigmentation, drusen, and fibrous metaplasia, and to describe the effect of treatment on FAF. METHODS Retrospective chart review of 23 consecutive patients with choroidal nevi and melanoma who underwent FAF photography. Th...

Extrapleural solitary fibrous tumors are being increasingly reported. The retroperitoneum, deep soft tissues of the proximal extremities, abdominal cavity, trunk, head and neck are among the most common extraserosal locations reported. A recurrent solitary fibrous tumor involving the vagina of a 25-year-old woman is reported. Microscopically, the tumor was hypercellular and composed of mitotica...

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...

We report a case of pancreatic hamartoma-like solitary fibrous tumor which was differentiated from pancreatic hamartoma with the detection of NAB2-STAT6 fusion, a specific mutation for solitary fibrous tumors. A pancreatic well-demarcated solid nodule, 21 × 17 mm, of 82-year-old man was surgically enucleated. Microscopic findings were close to a pancreatic hamartoma that consisted of sparsely d...

Solitary fibrous tumors are neoplasms of mesenchymal origin that may occur virtually in any body part, most commonly arising from the pleura. Solitary fibrous tumor of the kidney is exceptionally rare, and limited clinical knowledge regarding its behavior makes prognosis of the neoplasm difficult. We report a case of solitary fibrous tumor of the left kidney and describe its clinical, imaging, ...

Cranial malignant fibrous histiocytomas are rare tumors. Most are hypervascular, destructive masses that are similar to other malignant lesions and to malignant fibrous histiocytomas found elsewhere in the body. We describe a myxoid malignant fibrous histiocytoma of the temporal bone, possibly of dural origin, with features that more closely resembled a meningioma at CT, MR imaging, and angiogr...

INTRODUCTION Solitary fibrous tumors of the central nervous system usually present as dura-based masses and clinically resemble meningiomas. There are very few reported cases of intra-ventricular solitary fibrous tumors, particularly in the fourth ventricle. CASE PRESENTATION Our patient was a 52-year-old African-American man, who presented to our facility with a two-month history of progress...
