Abstract
Chondroid lipoma is a rare, benign tumor that may mimic soft-tissue sarcoma clinically. Its histopathologic features may resemble hibernoma, myxoid liposarcoma, myxoid chondrosarcoma, and other lipomatous or chondroid neoplasms. In this study, a chondroid lipoma was analyzed by fine-needle aspiration cytology, histopathology, electron microscopy, chromosome banding, and metaphase fluorescence in situ hybridization. The results demonstrate that chondroid lipoma exhibits a characteristic pattern by fine-needle aspiration cytology, including a mixture of benign adipose tissue with lipoblastlike cells, and chondroblastlike cells with a fibrochondroid matrix. Cytogenetically, a three-way rearrangement between chromosomes 1, 2, and 5 was found,... (More)
Chondroid lipoma is a rare, benign tumor that may mimic soft-tissue sarcoma clinically.

The results demonstrate that chondroid lipoma exhibits a characteristic pattern by fine-needle aspiration cytology, including a mixture of benign adipose tissue with lipoblastlike cells, and chondroblastlike cells with a fibrochondroid matrix. Cytogenetically, a three-way rearrangement between chromosomes 1, 2, and 5 was found, together with an 11;16 translocation with a breakpoint in 11q13, approximately 1 Mb proximal to the MEN1 region shown to be rearranged frequently in hibernoma. The presence of a karyotype of low complexity, but without any of the genetic aberrations characteristic for other types of soft-tissue tumors, indicate that chondroid lipoma develops along a unique pathogenetic pathway.
