Background: Eccrine porocarcinoma (EPC) is rare malignant cutaneous adnexal tumor. Since 1998, many EPC cases has been reported in Korea. All previous studies were limited to case report and none has comprehensively reviewed multiple cases. Objectives: To clinicopathologically review all EPC cases from our institutions as well as case reports in Korea. Methods: The patients were retrospectively selected from skin biopsy registry from our institutions. Available histopathological slides were re-examined by an experienced dermatopathologist. EPC cases reported in Korea before June 2019 were retrieved by searching PubMed, Google scholar, KoreaMed, and KoMCI. Results: Nine EPC cases from our institutions were included in the study. In addition, we found 27 reports of 28 EPC cases from Korea. In total of 37 EPC cases, there were 19 males (M:F ratio 1.06:1), and the mean age at diagnosis was 65.6 years. The most common site of primary tumor was head and neck (29.7%). Wide excision was the most common (78.4%) treatment method. Metastasis was confirmed in 21.1%. Conclusion: EPC is rarely reported cutaneous carcinoma in Korea. EPC usually affects old age patients with no sexual predilection. Due to possible metastasis, careful diagnosis and appropriate metastasis work up is warranted in EPC.
