Minor trauma-induced eccrine porocarcinoma of the toe in a patient on long-term carbamazepine: a case report and literature review

This case highlights the importance of considering rare malignancies like Eccrine Porocarcinoma in the differential diagnosis of non-healing acral ulcers. An early biopsy is crucial. The long-term use of carbamazepine in this context is noted, and its potential role as a co-factor in tumor development, possibly interacting with local chronic inflammation, is discussed. Further investigation into the influence of systemic medications on the pathogenesis of such rare tumors is warranted.
