Plexiform Neuroma.—Plexiform neuroma is always tumor may not be detected at the time of birth, but it is alwaysfound in children and young adults, and the clinical history frequentlydates back to early infancy. In most of the cases that have been ex-amined carefully the mass of the tumor was composed of fibrous tissuein which the nerves were found imbedded. Bruns found in some speci-mens a marked increase of nerve-fibres. The tumors are found mostfrequently in the temporal region, the neck, and the side of the face,but they may affect almost any part of the body. Christot reportstwo cases in which the tumors were located upon the cheek and theneck. Czerny observed a case in which the tumor involved the lumbarplexus. In this case the patient was also the subject of a very largecongenital fibroma of the skin. He found in the tumor, besides fibrous.

Campbell de Morgan metwith a plexiform neuroma of the musculo-spiral nerve and its branches(Fig. 378). The patient was a young lady. The tumor, which was notpainful, had undergone myxomatous degeneration. Plexiform neuromata are painless tumors which grow slowly, butwhich may attain large size. The affected nerves become tortuous,because they increase in length as well as in circumference. The rami-fications correspond with the directions of the branches of the nervesthat become successively involved. Thorough excision of the tumoris the only proper surgical treatment. Vulva.—Neuroma of the vulva is a pathological curiosity. In onecase reported by Simpson the tumor appeared as a painful nodule nearthe urinary meatus. Another case is reported by Kennedy.
