These men mutants fell into two groups: group I, in which the nutritional requirement was satisfied either by o-succinylbenzoic acid or by 1,4-dihydroxy-2-naphthoic acid; and group II, comprising those capable of(More)
Mixed mesodermal tumors are uncommon outside the uterus. Nine extrauterine mixed mesodermal tumors (eight ovarian and one extragenital) were selected for histochemical and immunoperoxidase study. In eight cases, both epithelial and mesenchymal elements were malignant (chondroid in six, rhabdomyoid in four, and osteoid in two). One ovarian tumor was an(More)
Blastocystis hominis is a unicellular organism the pathogenic potential of which in humans remains unclear. It may be identified during a workup for gastrointestinal symptoms, usually in stool examined for ova and parasites. We describe a case in which B hominis was identified by cytologic examination in a patient with Crohn's disease who underwent(More)
