ABSTRACT
Actinomycosis is a rare infection of the middle ear. Actinomyces is an anaerobic, filamentous bacterium causing granuloma formation and suppurative infection. We present a young male with a nine-month history of unilateral, yellow-coloured otorrhoea and hearing loss. Swabs showed no growth, with the infection not responding to oral or topical antibiotics. Computed tomography of temporal bones was consistent with cholesteatoma and ossicular disruption. Surgical exploration revealed a yellow, cystic mass within the middle ear. Cortical mastoidectomy and washout were performed. Histological diagnosis confirmed Actinomyces clusters with positive gram stain. Actinomycosis of the middle ear typically presents as chronic otitis media. It likely reaches the middle ear via the eustachian tube. It is often misdiagnosed due to culture insensitivity; however, clinical suspicion can aid labs in providing an optimum culture environment. Tympanomastoidectomy allows for histopathological diagnosis. Surgical resection should be followed by a prolonged course of antibiotics.
ABSTRACT
We present the case of a 23-year-old woman with aggressive fibromatosis of the oropharynx that was initially treated elsewhere as a peritonsillar abscess. We discuss the characteristics of this rare tumor and review the literature, stressing the importance of postoperative follow-up for peritonsillar abscesses to avoid missing other important diagnoses, such as the one described here.
