Nh. Cox et al., Amyloid deposition in basal cell carcinoma: a cause of apparent lack of sensitivity to radiotherapy, CLIN EXP D, 26(6), 2001, pp. 499-500
We describe a patient with a large nodular basal cell carcinoma (BCC), whic
h was excised following apparent failure to respond to radiotherapy. Histol
ogical examination of the fully excised lesion demonstrated a solid mass of
amyloid, which stained positively for cytokeratins, but there was no resid
ual BCC.
