    Early studies mentioned prevalence in obese postmenopausal women. However, current literature demonstrates that Dercum disease is present in more women than men of all body types; the average age for diagnosis is 35 years. [20] Benign symmetric lipomatosis (Madelung disease) is another

    A hamartoma is a mostly benign, [3] local malformation of cells that resembles a neoplasm of local tissue but is usually due to an overgrowth of multiple aberrant cells, with a basis in a systemic genetic condition, rather than a growth descended from a single mutated cell (monoclonality), as would typically define a benign neoplasm/tumor. [4]

  8. Fibroadenoma - Wikipedia

    en.wikipedia.org/wiki/Fibroadenoma

    Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...

    The lipomas are well-encapsulated, slow-growing, benign fatty tumors. The distribution is defined as being focused in the trunk of the body and extremities. [2] Familial Multiple Lipomatosis can be identified when multiple lipomas occur in multiple family members that span different generations. [2] Some people may have hundreds of lipomas ...
