Only one case of endometrial transitional cell carcinoma (TCC) has bee
n previously reported in the literature, We report a second case, In b
oth the previously reported case and in this case there was a separate
focus of TCC in the adnexa, Both patients were treated with adjuvant
whole pelvic radiation and are alive and without evidence of disease a
t 5 years and 15 months, respectively, Study of more cases of endometr
ial TCC is needed to determine whether this type of endometrial carcin
oma has a more favorable response to radiation therapy than other type
s of endometrial carcinoma with extrauterine spread. (C) 1996 Academic
