A t(X;10)(q22;q23.2) translocation was detected as the only chromosoma
l aberration in primary short-term cultured cells from on angiomyoma o
f a 58-year-old woman; 6p, 13q, and 21q rearrangements have been previ
ously demonstrated by others in two cases of angiomyoma. This type of
translocation has not been reported in other benign tumors including l
eiomyomas and angiomyomas, although it has been defected in an ependym
oma. This is thought to be a third case of angiomyoma showing karyotyp
ic abnormalities.
