RESUMO
Nasopharyngeal adenoid cystic carcinoma is a rare tumour. Compared with others nasopharyngeal tumours, it is characterised by slow evolution but it is locally aggressive and has a high tendency to recurrences. Due to the rarity of cases, no consensus exists about treatment approaches. We report the case of 45-year-old-man with a locally advanced adenoid cystic carcinoma. The patient received concurrent chemoradiation and had a good objective response. After one year, he developed a paucisymptomatic lung metastasis. The follow-up showed local recurrence after 3 years. One cycle of chemotherapy was given but poorly supported. Carbon ion radiotherapy was proposed. The aim of this work is to review the literature concerning this rare malignancy and discusses treatment approaches in initial situations and during recurrences.
