fibroma

[fī′brō·mə]
(medicine)
A benign tumor composed primarily of fibrous connective tissue. Also known as fibroid tumor.

Fibroma

 

a mature benign tumor of connective tissue, which can occur in any part of the body. Fibromas may be diffuse or encapsulated, depending on the nature of their growth. Fibroblasts are the source of fibromas, hence their other name, fibroblastomas. The symptoms and the course of a fibroma depend on the site and the rate of growth. Malignant degeneration sometimes occurs. Fibromas are treated surgically.

Because stains for ana-plastic lymphoma kinase-1 and [beta]-catenin were negative in all the above subtypes, there seemed to be no correlation between testicular/paratesticular fibrous pseudotumour and inflammatory myofibroblastic tumour or fibromatosis seen in other organs.[sup.5] Historically, fibrous pseudotumours have been referred to by multiple names including fibromatous periorchitis, nonspecific paratesticular fibrosis, nodular fibropseudotumour, reactive periorchitis, fibroma, fibrous pseudotumour, pseudofibromatous periorchitis, proliferative funiculitis and several others.[sup.2,5,6] However, because some lesions lack inflammatory component and are not nodular, the less specific term "fibrous pseudotumour" was preferred.[sup.5]
