“…In fact, periosteal chondromas involving finger phalanges were confused with primary subcutaneous or skin tumors at initial presentation [3, 4]. Clinicians should therefore be aware of the possibility of periosteal chondroma when evaluating subcutaneous lesions in the fingers.…”

“…It is usually small, measuring less than 3 cm in diameter, and can erode the underlying cortex without penetrating into the medullar cavity. Patients with periosteal chondromas of the fingers are usually asymptomatic and they complain only focal swelling or palpable masses [3, 4]. The pathogenesis of periosteal chondroma is poorly understood, but isocitrate dehydrogenase 1 ( IDH1 ) mutations have been identified in 71% of cases [5].…”

Periosteal chondroma is a rare benign hyaline cartilage neoplasm that occurs most commonly in the metaphases of long tubular bones. We present a unique case of periosteal chondroma arising in the proximal phalanx of the left index finger in a 12-year-old boy. Physical examination revealed a slightly protuberant, subcutaneous mass. Plain radiographs and computed tomography scans showed a periosteal lesion producing saucerization of the cortex and subjacent cortical sclerosis, without internal matrix calcification. On magnetic resonance imaging, the lesion exhibited intermediate signal intensity on T1-weighted images and high signal intensity on T2-weighted images. Contrast-enhanced fat-suppressed T1-weighted images demonstrated peripheral and septal enhancement. The patient underwent a marginal excision with curettage of the underlying bone cortex. Histological examination confirmed the diagnosis of periosteal chondroma. There has been no evidence of local recurrence eight months after surgery. Periosteal chondroma can protrude into the subcutaneous soft tissue causing a palpable mass. Recognition of the typical radiological features can lead to an accurate diagnosis of this rare condition.

“…Chondrome können auch als periostale oder juxtakortikale Chondrome meta-oder diaphysär am Humerus auftreten, selten treten sie als Weichteiltumor an den Fingern auf (Yildirim 2011). Sie stammen wahrscheinlich aus bindegewebigem Stroma und treten dominant an Händen und Füßen, bei 80 % an den Fingern auf.…”
