  ABSTRACT: Recurrent eccrine syringomatous carcinoma is an extremely rare adnexal tumor predominantly found in the head and neck region. We present a case of a 75-year-old woman with a 7-year history of recurrent syringoid eccrine carcinoma in the scalp and auricle. She had undergone five previous oncologic resections and declined further oncologic ablation of the auricle, including temporal bone and external ear canal resection. We performed five sessions of palliative photodynamic therapy using topical aminolevulinic acid HCL 20% (ALA) and between 25 and 33 pulses of Intense Pulsed Light (Quantum) with an intensity of 30 Joules. The ALA incubation time was 3 hours, while the time between each session was 4 weeks. This treatment helped to control ulceration, pain, and swelling. We saw the patient 1 month after the last treatment, by that time she moved and we lost contact.
