Results of Surgical Treatment of Patients with Malignant Eccrine Poroma

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.

Malign ekrin poroma’ da cerrahi tedavi sonuçlarýnýn deðerlendirilmesi

Giriþ: Malign ekrin poroma nadir görülen bir deri malinitesidir. Bu çalýþmada malign ekrin poromasý olan ve cerrahi olarak tedavi edilmiþ olan hastalarýn tedavi sonuçlarý deðerlendirilmiþtir.
Metot: 2012 ve 2018 yýllarý arasýnda malign ekrin poroma nedeniyle opere olmuþ hastalar çalýþmaya dahil edildi. Yaþ, cinsiyet, anatomik lokalizasyon, histopatolojik özellikler ve tedavi yaklaþýmlarýna göre hastalar deðerlendirmeye alýndý.
Sonuçlar: Ortalama tümör çapý 2.53 cm (0.3-7 cm) ve ortalama tümör kalýnlýðý 3.06 mm (2.5-4 mm) olarak bulundu. Ortalama cerrahi tümör marjini 1. eksizyon sonrasý 1.28 mm ve 2. eksizyon sonrasý 8.83 mm olarak bulundu. Takip döneminde nüks veya uzak metastaz saptanmadý.
Tartýþma: Sýk rastlanan deri kanserleinin aksine malign ekrin poromalarýn randomize çalýþmalar ile belirlenmiþ tedavi algoritmalarý bulunmamaktadýr. Bu hastalarýn tedavi sonuçlarýnýn planlanmasýnda hasta serilerinin sonuçlarýnýn cerrahi tedavisinin planlanmasý noktasýnda çok önemli olduðunu düþünüyoruz.
