Advanced Invasive Extramammary Pagets Disease Concomitant with Cecal Cancer Possessing Rare Variant of TP53 Single Nucleotide Polymorphism

摘要

Patients with invasive extramammary Paget's disease have an increased risk of secondary malignancy, mostly occurring colorectal carcinoma. TP53 is a regulator of apoptosis, cell cycle arrest, and DNA damage response pathways, and has been reported as one of the genetic biomarkers for colorectal carcinoma. In this report, we describe a case of advanced invasive EMPD concomitant with cecal cancer with a rare variant of TP53 single nucleotide polymorphism (rs121912665). To our knowledge, there is no English report that presents EMPD concomitant with cecal carcinoma.
