Abstract: Objective: To report two cases of pigmented eccrine poroma (PEP) and to review the related literatures. Methods: Twenty three patients with PEP in the reports in the last 30 years were analyzed. Results: PEP showed a higher prevalence of female patients without evident predilection sites. Clinically, PEP usually presents as a solitary, well-defined, partially blackish papule or nodule. The histopathological characteristics are monomorphic basaloid cells with poroid differentiation, and colonization of melanocytes and melanin. Conclusion: PEP has different clinical characteristics with eccrine poroma, including gender and location. It is clinically confused with pigmented skin tumors, thus the diagnosis usually depends on the histopathological examination.
