Virchow describes and recognizes an hereditary fibromatousdisposition, and he alludes to an instance of the occurrence of multiplesubcutaneous fibromata in members of the same family in three con-secutive generations. Symptoms and. Diagnosis.—The growth of a fibroma is alwaysslow. A simple, uncomplicated fibroma attains a certain limited sizeand then remains stationary. The large cystic fibroids described insome of the older text-books were sarcomata, as it is often stated thatthe tumor reached the size of a childs head in a year or less. Fibromanever pursues such a rapid course. Uterine myofibromata grow morerapidly than simple fibroids, are more vascular, and the muscular fibres.

The tumor issmooth and is always well encapsulated, hence movable unless restrainedby adjoining firm resisting tissues. A fibroma of the breast can be movedamong the tissues between two fingers without moving the gland—animportant point in the differential diagnosis between fibroma and carci-noma. The tumor displaces, but does not infiltrate, the adjoining pressure of a periosteal fibroma frequently results in great displace-ment of the bone by bending and by pressure-atrophy. If the tumoroccupies a cavity, it may interfere with important functions. A fibromaof the nasal cavity interferes with respiration, and, when it reaches thepharynx, with speech and deglutition. A fibroma of the uterus, ifsubmucous, causes hemorrhage; if subserous, it may by its
