Eccrine syringomatous carcinoma of the skin

Abstract

S356reports of practical oncology and radiotherapy 1 8 ( 2 0 1 3 ) S355-S358 metastases 2 months after treatment. Secondly, we report a 79-year-old man with an ulcer in the left ear. It was excised. Pathology showed EP with close surgical margin; it was widened. Workup showed no distant metastases. In February 2010 conformational 3-D RT was administered (30 sessions). Treatment volumes: PTV1:tumor bed (TD: 60 Gy); PTV2(TD: 54): left preauricular and cervical lymph node levels II-III. PTV1 was treated with a direct field (6 MeV electrons). The patient had acute toxicity: RTOG G1 dermatitis and alopecia and is in complete remission (2-year follow-up). Conclusions. EP diagnosis and management is difficult. Optimal treatment remains unknown. Early diagnosis and wide local excision show best results. Adjuvant RT can help achieve local control in EP with adverse factors, and in local and locoregional recurrences.http://dx.
