Objectives: Malignant eccrine poroma is a rare cutaneous malignancy. This study was a review of a series of patients with malignant eccrine poroma who underwent surgical treatment conducted in order to evaluate the management techniques and outcomes of treatment modalities.
Methods: All cases of surgically excised malignant eccrine poroma performed in a single clinic between 2012 and 2018 were included in the study. The details of patient age, gender, anatomical location of the tumor, histopathological features, and treatment modalities were analyzed.
Results: The average tumor size was 2.53 cm (range: 0.3-7 cm). The average tumor thickness was 3.06 mm (range: 2.5-4 mm). The mean clean tumor margin after the first excision was 1.28 mm and the mean tumor margin after the second excision was 8.83 mm. No recurrence or distant metastasis was detected in any of the patients during the follow-up period.
Conclusion: Unlike frequent skin cancers, rare skin cancers, like malignant eccrine poroma, don't have definite treatment algorithms constituted from randomized trials. The findings of patient series are very useful to guide physicians in these cases.
Keywords: Eccrine porocarcinoma; malignant eccrine poroma; skin cancer.
