Fibroadenoma(redirected from Fibroadenomatosis)
Also found in: Dictionary, Thesaurus, Medical.
a mature benign tumor of connective and glandular tissues. A fibroadenoma develops in organs with a glandular structure, such as the breast and the prostate. It grows slowly, is clearly demarcated from the surrounding tissues, and is often encapsulated. The symptoms depend on the site: moderate tenderness of the breast if the mammary gland is affected and difficulty of urination, including acute retention of urine, if the prostate is involved. Malignant degeneration is possible. Fibroadenomas are treated surgically.
