Lesions of toxoplasmosis in the perirenal adipose tissue of aborted kids

Extract

Madam:—During July of 1986, a number of aborted Angon kids were received in our laboratory for routine diagnosis on the cause of abortion and they were diagnosed pathologically and serologically as being due to toxoplasmosis. Apart from classical microscopiallesions in the brain, lung, myocardium, liver and kidney of the aborted kids and the placentae of the does, we noted a prominent steatitis and periarteritis in the perirenal adipose tissue. These lesions were multiple and random in distribution and were characterised by infiltrations of mononuclear cells (Fig. 1). The changes were consistently present in the perirenal fat of all aborted foetuses in which Toxoplasma infection was established. Occasionally, Toxoplasma pseudocysts could be found in association with these inflammatory foci (Fig. 1.). In addition, pseudocysts and occasional groups of tachyzoites were found in the other tissues.
