An angiomyoma with t(X;10)(q22;q23.2).

A t(X;10)(q22;q23.2) translocation was detected as the only chromosomal aberration in primary short-term cultured cells from an angiomyoma of a 58-year-old woman; 6p, 13q, and 21q rearrangements have been previously demonstrated by others in two cases of angiomyoma. This type of translocation has not been reported in other benign tumors including leiomyomas and angiomyomas, although it has been detected in an ependymoma. This is thought to be a third case of angiomyoma showing karyotypic abnormalities.
