title: Amyloid deposition in basal cell carcinoma: a cause of apparent lack of sensitivity to radiotherapy.
abstract: We describe a patient with a large nodular basal cell carcinoma (BCC), which was excised following apparent failure to respond to radiotherapy. Histological examination of the fully excised lesion demonstrated a solid mass of amyloid, which stained positively for cytokeratins, but there was no residual BCC.
