Looks like a foreign body reaction with cystic formation. Figure 3 shows vacuoles similar to silicon and the next figures shows calcified material and some pigments I don´t know what they are. I would ask if the patient was submited to any cosmetic procedure.

Foreign body granulomatous reaction to an injectable filler material. Could be silicone but I have seen silicone granulomas before, they tend to form vacuoles of variable sizes and shapes..

I think these round spaces of similar shape and size are not adipocytes but polymethylmethacrylate microspheres and this is Artecoll-related granuloma.

I agree with PMMA. Their microspheres are monomorphic and shows translucent non-birefringent material.

This is a a foreign body reaction to keratin flakes, seen in image 5 (presumed previously ruptured epidermoid cyst of long standing hence the dystrophic calcification). In an HIV positive patient receiving anti-retroviral drugs who has lipoatrophy (note uniform size of fat cells and lack of refractile or foreign material).

Thanks to Dr Nick Tiffin for sharing this wonderful case with me!!
