A Non-Classical Presentation of Oral Pyogenic Granuloma with Actinomycosis

ABSTRACT

Introduction: Pyogenic granuloma is a rather confusing reactive lesion of the oral mucosa, considering it is neither a bacterial infection nor does it produce any pus. In fact, even histologically, there is no formation of granulomas to substantiate the name. Intraoral actinomycosis is another interesting lesion due to its unique ability to masquerade itself as a swelling, abscess, or even a neoplasm. The occurrence of the two lesions separately is common in the oral cavity, however, their co-existence is extremely rare. Case Presentation A 65-year-old female patient was referred from a private dental clinic with the chief complaint of a growth on her left posterior region of mouth, at the occlusal level of 15, 18 tooth regions for past 1 month. Conclusion: Clinicians should be aware about the occurrence of such rare combination of intraoral lesions, in order to make an accurate diagnosis and in turn, tailor a correct treatment protocol for these patients.
