A Rare Case of Luc's Abscess in an Immunocompromised Female Patient.

Although Luc's abscess represents a rare complication of otitis media, it is an important complication to be considered by clinicians, by which infection spreads from the middle ear and can result in subperiosteal collection beneath the temporal muscle. Because of its rare occurrence, the diagnosis and treatment might be delayed. Here, we report the case of a 48-year-old female with Luc's abscess with the involvement of the mastoid bone and discuss its clinical presentation and successful management.
