The recurrence risk of 'pushing' eccrine porocarcinoma is significantly lower than for 'infiltrative' eccrine porocarcinoma. Based on these considerations, a decisional algorithm might be proposed: first step, excisional biopsy of the primary eccrine porocarcinoma and identification of the histological subtype; second step, infiltrative or pagetoid porocarcinoma should be excised with an additional modified micrographic Mohs procedure, while no additional surgery is needed for 'pushing' eccrine porocarcinoma if the first excisional biopsy is complete. Although demonstrated in a limited case series, the histological subtype might guide the surgical management of primary eccrine porocarcinoma.

Neoadjuvant chemotherapy can be considered as a new criterion for better selection of candidate patients for lung metastasis surgical resection. This would also avoid useless surgical procedures in rapidly progressive disease and give information on the chemosensibility of the metastatic disease. This study needs further confirmation, particularly with chemotherapy regimens that have demonstrated better objective responses.
