Abstract

Extraskeletal chondroma is a benign soft tissue tumor which is composed of hyaline cartilage but arises from the fibrous stroma rather than from mature cartilaginous or osseous tissue. Extraskeletal chondroma is relatively rare and occurs most frequently in the soft tissue around the joints of hands and feet. We present one case of extraskeletal chondroma in a finger of a young woman.

Keywords: extraskeletal chondroma, finger

Figure 3.

Ultrasonograph shows an ovoid-shaped non-echoic lesion in right 5^th finger middle phalanx, which measures 0.3×0.3×1.0 cm. (A) Axial view, (B) Saggital view.

Figure 4.

MRI shows a well demarcated ovoid mass of T1 low to intermediate and T2 intermediate signal intensity. There was marked diffuse heterogeneous enhancement throughout the lesion following the administration of intravenous contrast.

Figure 5.

Photographs show a gray-whitish, nodular soft tissue mass. The tumor rested upon the digital nerve.

Pathologic features of extra-skeletal chondroma. (A) The tumor consists of the circumscribed lobules of mature hyaline cartilage. The chondrocytic tumor cells are identified in lacunae (Hematoxylin & Eosin, ×200). (B) The tumor cells of the extraskeletal chondroma are positive with S100 protein as with normal chondrocytes (Immunohistochemistry, ×200).
