[Actinomycosis sub-masseter abscess, simulating a parotiditis. Review of case and revision of literature].

We present one case of a pluripathologic female patient who has developed an submaseterin abscess secondary to an actinomyces mandibular osteomielitis. The initial presentation seems an acute supurative parothiditis. We describe its presentation, evolution, special tests done for its diagnostic, as also the discussion of the type and duration of the treatment. And we include also a differential diagnosis between the two diseases, with a similar form. We do also a bibliographic revision of the few similar cases published.
