Abstract

Extraskeletal chondromas are benign soft tissue tumor of hyaline cartilage. These tumors are rare and the pathogenesis is unclear. They are usually involves the hand or feet. We report the case of extraskeletal chondroma arising from subungual region of the finger with nail deformity and review of the literature.

Keywords: Chondroma, Finger

Figures and Tables

Fig. 1

Clinical photograph of the right fifth finger. A mass lesion can be seen arising from lunula. Nail deformity and discoloration in nail plate observed.

Fig. 2

Anteroposterior radiographs of both hands. The distal phalanx deformation of the right fifth finger observed

Fig. 3

T1-weighted sagittal image revealed a well-demarcated mass in subungual region with low signal intensity.

Fig. 4

After total nail extracted, white and firm mass showed without connection to underlying bone.

Fig. 5

Low power photomicrograph shows a well-demarcated mass with lobules of abundant hyaline cartilage matrix (Hematoxylin and Eosin stain, ×40).

Fig. 6

On high power section, the hypercellular hyaline cartilage is composed of chondrocytes which have uniform small round nuclei and finely granular, eosinophilic cytoplasm. Binucleation and slight cellular atypia of chondrocytes are focally seen (Hematoxylin and Eosin stain, ×200).
