In the specimen the villi are considerably hypertrophied, giving the surface a plush-like aspect. The patient died in the
CASE 881.—Autopsy: The only point which attracted attention was the condition of the intestinal canal. The solitary follicles throughout the ileum were enlarged, and there was slight thickening of the patches of Peyer, several of which presented one or more minute ulcers. The colon was closely studded with minute follicular ulcers about the size of pin-pricks.
Nos. 600 and 601, Medical Section,
The plate facing page 302 is a reproduction of a photograph of No. 600, which represents it of the natural size. The mucous surface of the piece is marked by a number of transverse rugæ, which are the imperfectly-developed valvulæ conniventes. The hypertrophy of the villi gives the whole mucous surface a plush-like appearance which is exceedingly characteristic, and which can be studied advantageously with a lens. A number of enlarged solitary follicles the size of pin-heads project slightly above the mucous surface as rounded elevations. In the lower half of the specimen there is a Peyer's patch two inches and a half long by three-quarters of an inch wide at its broadest part. The position of this patch is plainly indicated by the absence of the transverse rugæ above referred to, which terminate rather abruptly at the margins of the patch. The surface of the patch, which is not materially elevated above the surrounding mucous membrane, is marked by irregular narrow transverse broken lines, on which are seated numerous hypertrophied villi similar to those of the surrounding mucous membrane; between these are narrow irregular areas on which there are no villi, and which, hence, appear somewhat depressed below the general surface. The general effect of this arrangement is to give the surface of the patch a somewhat reticulated appearance. At the center of the patch there is a shallow oval ulcer an eighth of an inch in diameter. A little more than half an inch below this, near the right-hand margin of the patch, is another similar ulcer, and a third smaller one will be noticed at the upper extremity of the patch.
