BACKGROUND/AIM: Myofibroblastoma of the breast is a rare benign mesenchymal tumor whose morphology is similar to that of spindle-cell lipoma. The few hitherto genetically investigated mammary myofibroblastomas have been shown to have had loss of material from chromosome 13, changes that are also common in spindle-cell lipoma. Our aim was to add to the existing knowledge of genetic aberrations in mammary myofibroblastoma by investigating another such tumor.
MATERIALS AND METHODS: Cytogenetic and array comparative genome hybridization (aCGH) analyses were performed on a surgically removed mammary myofibroblastoma from a 76-year-old man.
RESULTS: Short-term cultured cells from the tumor showed the karyotype 45,XY,-13[3]/44~45,idem,add(19)(q13)[cp2]. aCGH detected loss of one entire chromosome 13 and heterozygous loss from 19q between sub-band 19q13.12 and 19qter.
CONCLUSION: These findings add to the evidence that loss of 13q material is typical of mammary myofibroblastomas.
