Abstract
Introduction: The rate of squamous cell carcinoma spontaneous regression (SR) remains unknown because incidences are rare and underreported. Case Report: We present a case of a 92 - year-old Caucasian female who was found to have a 1 cm lesion on her nose. Pathologic evaluation supported the diagnosis of a moderately-differentiated squamous cell carcinoma. The patient refused treatment and returned with no clinical evidence of disease several months later. The lesion spontaneously regressed without excision. Discussion: Frequency of SR of malignancies has been estimated to occur 1 in 80,000 to 100,000 cases [1]. The biologic mechanisms of SR in malignancies remain unclear. Further inves tigations into the mechanisms of SR may identify potential treatment strategies for cancer.
