Translocation (2;11)(q31;q12) is recurrent in collagenous fibroma (desmoplastic fibroblastoma).
Collagenous fibroma (desmoplastic fibroblastoma) is a rare, benign tumor composed of spindle and stellate-shaped fibroblasts and myofibroblasts in a densely collagenous background. A t(2;11)(q31;q12) has been reported in one case of collagenous fibroma and a rearrangement of the 11q12 breakpoint in a second case. In the present study, we detected a t(2;11) identical to that previously described in a collagenous fibroma arising in the supraclavicular fossa of a 55-year-old man. This finding confirms the nonrandom association of t(2;11)(q31;q12) with collagenous fibroma.
