Abstract: Chronic papillomatous dermatitis (CPD) is a stoma site complication due to chronic irritant contact dermatitis. Papillomatosis can also arise in the setting of Human Papillomavirus (HPV) infection or chronic lymphedema (elephantiasis). Herein, we report the case of a 57-year-old female who presented with a papillomatous growth surrounding a loop ileostomy suspected to be recurrent ovarian serous carcinoma. Excisional biopsy demonstrated nevus sebaceous (NS)–like organoid hyperplasia with koilocytes overlying a dermal scar that exhibited lymphangiectases. Polymerase chain reaction and sequencing for HPV DNA detected HPV 16. In situ hybridization for high-risk HPV DNA showed punctate nuclear pattern in the keratinocytes populating the NS-like hyperplasia indicating integrated HPV 16 DNA. No recurrence has been observed 11 months postexcision. Reports of CPD have documented a spectrum of reactive epidermal hyperplasias including pseudoepitheliomatous, verrucous, papillomatous, syringofibroadenomatous, and rudimentary follicular hyperplasias. HPV DNA has been detected in 3 of 4 CDP cases tested to date and in authentic NS. We postulate that localized lymphedema secondary to scarring coupled with chronic epidermal irritation and inflammation allowed for latent HPV infection to manifest as CPD with NS-like cutaneous hyperplasia.
