title: Subungual squamous cell carcinoma: A case study.
abstract: The purpose of this case study is to describe a dosimetric delivery of radiation to a superficial disease process involving the skin and bone of the distal finger. A 76-year-old male patient presented with a subungual squamous cell carcinoma (SCC) of the left distal index finger with bony involvement. The patient refused conventional surgical treatment but agreed to external beam radiation therapy (EBRT). There is a gap in the current literature describing how to successfully immobilize fingers and which EBRT modality is dosimetrically advantageous in treating them. The construction of a simple immobilization method with the patient in a reproducible position is described. The use of photons and electrons were compared ultimately showing photons to be dosimetrically advantageous. Long-term efficacy of the treatment was not evaluated because of patient noncompliance.
