Foreign body granulomas can occur after the injection of dermal fillers, showing various clinical and histologic features depending on the type of injected filler. The reported incidence of foreign body granulomas after filler injection varies. Hyaluronic acid and collagen are the most commonly used filler materials.

2022年8月5日 · Epithelioid granuloma: loose or discrete aggregates of eosinophilic histiocytes / macrophages with variable giant cell formation and variable central caseation / necrosis; usually small, focal and nonnecrotic; often paratrabecularly located; many subtypes; characteristic features for certain causes but not specific

Four histologic patterns were found: (i) Artecoll, (ii) Dermalive, and (iii) New-Fill granuloma, all three of the classic giant cell granuloma type, differing in respect of foreign particles; and (iv) Liquid Silicone granuloma, which featured a cystic and macrophagic type.

Foreign body granuloma is a reaction to exogenous materials (talc, suture material, parasites, oil droplets, wood, metals, silica, silicon) or endogenous (hail shafts, keratin, cholesterol, urates / goutous tophi), which are immunologically inert.

Foreign body granulomas can occur after the injection of der-mal fillers, showing various clinical and histologic features de-pending on the type of injected filler. The reported incidence of foreign body granulomas after filler injection varies. Hyaluronic acid and collagen are the most commonly used filler materials.

Histology of subcutaneous foreign body granuloma formed by implantation of particles of prosthetic biornaterials, showing the associated heavy macrophage and macrophage polykaryon...

2015年3月1日 · The objective of this case report is to describe the successful treatment of foreign body granulomas caused by polymethylmethacrylate microspheres using allopurinol, an innovative therapy for...

2015年3月15日 · Foreign body granulomas may occur after the administration of any dermal filler. Factors such as the volume of the injection, impurities present in the fillers, and the physical properties of fillers affect granuloma formation. The formation of granulomas involves five phases: protein adsorption, macrophage adhesion, macrophage fusion, and ...

The authors report 2 cases of foreign body inflammatory giant cell reaction in patients who underwent orbital fracture repairs with porous polyethylene implants. Porous polyethylene is commonly used in the orbit for fracture repair and anophthalmic reconstruction; it reportedly has a good safety profile and integrates well into host tissue.

Histology and immunohistology was conducted for assessment of the foreign body reaction. Regular and modified TPU threads showed a significant reduction of incision into the tissue surrogates...
