| An
incidental finding of chondroid lipoma at total hip arthroplasty.
J Surg Orthop Adv. 2004 Spring;13(1):42-3.
Chondroid lipoma is a
rare benign lipomatous soft tissue tumor which presents as a painless lump.
This case report presents the incidental finding of such a tumor at total
hip replacement and briefly reviews the literature regarding the
histopathological features of this recently described neoplasm.
Diagnosis of chondroid lipoma
by fine-needle aspiration biopsy.
Arch Pathol Lab Med. 2001 Sep;125(9):1224-6.
Chondroid lipoma is a
rare, recently described soft tissue tumor that mimics extraskeletal
chondrosarcoma and myxoid liposarcoma. Reports regarding its cytologic and
radiological features are sparse. In this report, we describe the cytologic
features of this unusual tumor, which include mixed mature lipocytes and
lipoblast-like cells embedded in chondromyxoid matrix. We also describe the
"target sign appearance" of this tumor in magnetic resonance imaging
studies, resembling a neurogenic tumor. More importantly, we demonstrate
that a definitive diagnosis of this unusual tumor can be made by fine-needle
aspiration biopsy. The usefulness of cell block in fine-needle aspiration
biopsy diagnosis of soft tissue tumors is emphasized. |
