The microscopic appearance of a pyogenic granuloma consists of highly vascular granulation tissue. This granuloma formation induces chronic inflammation. Presence of myxoid structures in the pyogenic granuloma may be the main cause of recurrence. The name "pyogenic granuloma" is misleading as it is neither pyogenic or a true granuloma. The characteristic morphological element is the tuberculous granuloma (caseating tubercule). Treatment for periapical granuloma is initially treated with a nonsurgical procedure. Your doctor will likely be able to diagnose a pyogenic granuloma based on its appearance. It is a type of inflammatory reaction known to pathologists as a "necrotizing granuloma". The lungs become inflamed, with granuloma formation. Talcum powder is dangerous if inhaled since it may cause aspiration pneumonia or granuloma. Bacteria inside the granuloma can become dormant, resulting in latent infection. The dot appears as a small granuloma which is composed of lymphocytes and macrophages. A fibrin ring granuloma may be seen. However, spines that remain embedded may cause inflammatory granuloma.
