Subungal squamous cell carcinoma of the thumb – Implications for patient setup and radiotherapy planning

Abstract

Subungal squamous cell carcinoma (SSCC) is a rare malignancy of the nail bed. We present the case of a woman diagnosed with a SSCC of the right thumb. Initial management consisted of surgically excision followed by adjuvant radiotherapy due to a positive bone margin. We describe the patient set-up, immobilisation technique, target volume delineation, radiotherapy planning, fractionation schedule, image guidance and patient outcomes.
