[Simultaneous presentation of actinomycosis and metastatic pharyngeal carcinoma].

Although actinomycosis frequently presents as a pseudotumoral syndrome, the simultaneous diagnosis of actinomycosis and cancer is exceptional. Actinomycosis can occur as an opportunistic infection secondary to the antineoplastic treatment and even the cancer itself can act as facilitating factor. We report a patient who was diagnosed simultaneously of advanced oropharinx cancer (T4-N1-M0) and actinomycosis associated to the tumoral mass. This exceptional association and the importance of its early diagnosis justify the communication of the case.
