Porocarcinomas are rare malignant eccrine sweat gland-derived tumors that are less than 0.005% of all malignant epithelial cutaneous tumors. These tumors, which are mostly seen in the lower extremities, are mostly seen in old age. They were first described in 1967 and until 2017, only 453 cases were reported in the world population.(1) There is no consensus on the natural course and definitive treatment methods of these tumors, which have a high likelihood of locoregional and lymph node metastasis.
In this study, we aimed to present four cases of porcarcinoma with different initial pathologic diagnoses (3 patients with punch Bx, 1 patient with incisional Bx confirmed by pathologic diagnoses) that were referred to our clinic between 2020 and 2022 and to review the existing literature on the management of this rare patient population. We aimed to contribute to the literature by answering the question of whether porocarcinoma cases, which are known to be extremely rare according to the literature, are actually more common than the rate stated in the literature or whether the diagnosis of porocarcinoma is missed due to misdiagnosis in our clinic in a short period of 3 years (between 2020-2022). A secondary aim of this study is to prevent misdiagnosis of this malignant tumor that can show rapid progression and to emphasize the importance of determining the appropriate surgical and adjuvant treatments.
