Abstract Background Porocarcinoma (PC) is a rare cutaneous adnexal tumor with variable metastatic potential. Given the paucity of data, guidelines and specific recommendations for PC are not yet well‐established. In this study, we evaluate disease‐specific characteristics outcome often underestimated tumor. Materials method A retrospective study epidemiological, clinical, dermoscopic among cases histopathologically diagnosed PC, collected from database two skin cancer clinics in Italy (Firenze, Pistoia) 2000 to 2020, was conducted. Results Among 52 patients 53 tumors, 31 were men (59.6%) 21 women (40.4%) an age range 49–96 years (median 82 years). The most common locations head/neck region (34% vs. 17% women) lower limb (17% 9% men). Forty‐eight (91%) underwent local excision. Of these patients, (4%) experienced recurrence, one (2%) developed second on different anatomical site 1 month after primary tumor's Lymph node metastases present three (6%). Two them have been treated surgically adjuvant radiotherapy (both disease‐free 2‐year follow‐up period), whereas third case visceral followed by PC‐related death. Conclusions This tumors covering period more than 5 years, shows less aggressive behavior 4% 6% nodal metastases, 2% mortality.
