Fig. 6. Old Retained Hydatiform Degeneration

No. 323. Xl.25.

No. 323

(1) V. Van Williams, Baltimore, Maryland.

(2) A 120X90x65 mm.

(4) The specimen was brought fresh to the laboratory and was found to be composed of enlarged villi and vesicles, most of which measure 5 mm. and a few fully 20 mm. in diameter. On one end the specimen is fibrous, and from there the villi extend into a bloody mass.

(5) The latter villi are very irregular in form, the mesqderm being hyaline, with numerous spindle-shaped nuclei. Between the villi there are great masses of necrotic trophoblast, some blood, and occasionally small masses of leucocytes. A few of them contain irregular clefts with cells, a clear fluid, and some coagulum.

(6) Slight infiltration and decided hydatiform degeneration.
