Granulomatous reaction triggered by foreign bodies.
They are the most common granulomatous diseases.
Trauma: After foreign bodies have penetrated the skin (milking granuloma, barber's granuloma, pilonidal sinus, sea urchin sting)
In the course of medical treatments (paraffin, sutures, silicone)
Body's own products: Gout (urate crystals), necrotic fatty tissue (lipophagic granuloma).
There is the expression of a granulomatous reaction, in the sense of a disorderly accumulation of macrophages with foreign body giant cells.
Skin-coloured, derb-palpable, well-defined nodules and plaques.
Different dermatopathological patterns are possible (sarcoid, necrobiotic granuloma, zirconium granuloma). The foreign bodies are detectable by polarisation optics.
