CASE PRESENTATION: A 15-year-old male was found to have a primary right distal femur osteosarcoma with multiple additional bony sites of disease. A <em>POT1</em> splice site variant (c.949+1G>C) was identified both somatically and in the germline consistent with POT1-TPD. Despite extensive multifocality, the tumor displayed marked chemosensitivity to standard of care therapy and long-term remission was achieved. DISCUSSION: Evidence suggests that hereditable alterations in telomeric function including <em>POT1</em> are enriched in sarcoma susceptibility. Furthermore, hereditary tumor predisposition syndromes often increase osteosarcoma risk including a recent report of five patients with POT1-TPD.
