Figure 2 Bone Fibrous osteodystrophy in a male F344/N rat from a chronic study (same animal as in Figure 1). There is replacement of cortical bone by fibrous connective tissue.

Background: Solitary fibrous tumor (SFT) is a mesenchymal tumor which is most commonly seen in the pleura; however it can be seen in other organs such as the meninge, gastrointestinal tract, soft tissue, bone, and skin. SFT should be differentiated from other mesenchymal tumors in these organs. Immunohistochemistry plays a pivotal role for the histopathologic diagnosis...

macrodystrophia lipomatosa is a rare congenital form of localized gigantism characterized by an increase in all mesenchymal elements, particularly fibroadipose tissue. mr imaging can be used to examine the soft tissue and detect the fibrous and fatty hypertrophy that characterizes this condition and also diagnose an associated fibrolipomatous hamartoma of the median or plantar nerve. we describ...

INTRODUCTION Calcifying fibrous pseudotumor is a rare benign soft-tissue lesion composed of fibrous tissue with abundant hyalinized collagen and dystrophic and often psammomatous calcifications. The cause of the disease is unclear but, usually, complete resection of the well-circumscribed tumor is sufficient to avoid recurrence of the disease. Here, we report an unusual case of this rare tumor ...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...
