title: Cytogenetic analysis of a hemosiderotic fibrolipomatous tumor.
abstract: Hemosiderotic fibrolipomatous tumor is an extremely rare, nonencapsulated, fatty lesion with a consistent histologic appearance that was originally considered reactive in nature. To our knowledge, there are no previous reports on the cytogenetics of this lesion. Reported here is a case of hemosiderotic fibrolipomatous tumor arising within the subcutaneous tissue of the right foot, dorsal aspect, of an otherwise healthy 35-year-old woman. Subsequent cytogenetic analysis revealed a clonal reciprocal translocation between chromosomes 1 and 10, with a further rearrangement involving this derivative chromosome 1 and chromosome 3. This, in addition to its characteristic morphology and immunophenotype, supports the neoplastic nature of this tumor and may aid in its diagnosis.
