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.
