A third case of a low-grade endometrial stromal sarcoma with a t(7;17)(p14∼21;q11.2∼21)

Cytogenetic analysis of a low-grade endometrial stromal sarcoma of the uterus in a 52-year-old woman revealed the karyotype 46,XX,t(7;17)(p14∼21;q11.2∼21),der(7)t(7;16)(p14–15;q22)t(7;9) (q22;q22), der(9)t(7;9)(q22;q22),del(16)(q22). The t(7;17) was identical to an aberration observed in two other cases of endometrial stromal sarcomas, thus confirming the idea that it constitutes a non-random aberration for this type of tumor.
