🦷 Oral Pathology Challenge Case

47-year-old patient with a destructive mandibular lesion.
The panoramic radiograph and histopathology picture are attached. 👇

So… what do you think this lesion is? 👀
What differentials would be on your list?
And which IHC markers would you ask for to confirm the diagnosis? 🧪

Waiting for your opinions 👇

Thank you all for your insightful comments and great engagement on the previous post 🙏

As many of you correctly identified, the three gingival swellings correspond to the following histopathological entities:

🔹 Pyogenic Granuloma (EG)
Characterized by a lobular proliferation of capillaries lined by plump endothelial cells, often with an edematous and ulcerated surface. It is typically triggered by local irritation or hormonal influences.

🔹 Peripheral Giant Cell Granuloma (PGCG)
Distinguished by the presence of multinucleated osteoclast-like giant cells within a hemorrhagic fibrous stroma, frequently with hemosiderin deposition. A helpful radiographic clue is the classic “cupping” resorption of the underlying bone.

🔹 Peripheral Ossifying Fibroma (POF)
Shows a fibrous connective tissue stroma containing calcified or ossified material—this is the key diagnostic feature. It commonly arises from the interdental papilla and carries a notable recurrence risk if not excised down to the periosteum.

Excellent work to everyone who participated 👏

Differentiating Fibrous Dysplasia from other fibro-osseus lesions is crucial as management differs!

Diffuse borders + ground-glass appearance + no ri***ng

Correlation is the key 🔑
