Abstract：Objective To summarize the clinical characteristics of eccrine poroma(EP)and to analyze the causes of misdiagnosis.Methods From August 2022 to November 2023,the clinical data of 10 patients who were initially misdiag-nosed as other skin diseases were retrospectively analyzed.Results Among the 10 patients,there were 4 males and 6 females aged 26-83 years,and the course of disease ranged from 2 months to 30 years.One patient had a history of scald before onset,and there were 3 cases of pigment type and 7 cases of non-pigment type.The initial diagnosis was pyogenic granuloma in 2 oat-ients,verruca vulgaris in 2 patients,cutaneous squamous cell carcinoma in l patient,pigmented nevus in 1 patient,unspeci-fied rash in 1 patient,unspecified skin mass in 1 patient,epidermal cyst in 1 patient,and basal cell carcinoma of the skin in 1 patient.All patients were ultimately confirmed as EP through histopathological examination.The misdiagnosis for 10 patients lasted approximately 1 week to 1 month.All patients were followed up for 8 months to 2 years after surgical resection,and there was no recurrence.Conclusion EP exhibits diverse clinical and dermoscopic manifestations with low specificity,requi-ring histopathological examination for definitive diagnosis.Clinicians should be familiar with the clinical features of EP and perform histopathological examination early when necessary to improve the diagnostic accuracy.
