Granuloma Types
Types of Granulomas Treated at Kare Plastic Surgery
Granulomatous inflammation occurs when the immune system mounts a sustained response to a material it cannot clear through normal phagocytosis — forming organized aggregates of macrophages, epithelioid histiocytes, and multinucleated giant cells. In a cosmetically active population like Los Angeles, foreign body granulomas from aesthetic procedures are among the most common presentations Dr. Sierro evaluates at Kare Plastic Surgery.
Silicone Liquid silicone injections — legal or illegal — trigger lipogranulomatous inflammation that can develop years after injection
Filler Delayed hypersensitivity to HA, CaHA, PLLA, or permanent fillers — nodules forming weeks to years post-injection
Allergic Immune-mediated granulomatous reaction to topical agents, metals, medications, or biologic treatments
Foreign Body Tattoo pigment, suture material, paraffin, or other implanted materials triggering granulomatous encapsulation
Sarcoidal Cutaneous sarcoidosis — non-caseating epithelioid granulomas requiring systemic workup and coordinated management
Important: Nodules, lumps, firmness, redness, or swelling appearing at a prior filler or silicone injection site — especially when developing months or years after the original procedure — should be evaluated by a board-certified dermatologist. These presentations can represent granuloma formation, biofilm infection, or other delayed complications that require biopsy confirmation before treatment. Empiric treatment without a confirmed histopathological diagnosis risks missing an underlying infection, malignancy, or systemic condition. Call Dr. Sierro at (310) 998-5533.
Silicone Granuloma
Among the most challenging granuloma presentations in Los Angeles — a city with a high volume of both historical illegal liquid silicone injections and modern silicone implant procedures. Silicone granulomas develop when injected silicone or implant-leaked silicone triggers a lipogranulomatous foreign body reaction. They present as firm, sometimes tender nodules that may enlarge, coalesce, or develop overlying skin changes. Biopsy demonstrates the characteristic vacuolar lipogranuloma pattern. Management ranges from intralesional steroid injection to surgical excision with the plastic surgery team at Kare Plastic Surgery.
Dermal Filler Granuloma
Delayed hypersensitivity granulomas can develop to any type of dermal filler — including hyaluronic acid (Juvederm, Restylane), calcium hydroxyapatite (Radiesse), poly-L-lactic acid (Sculptra), and permanent fillers. They typically present as firm nodules or indurated erythematous plaques at the injection site, appearing 2 weeks to 2 years post-injection. Hyaluronidase can dissolve HA filler granulomas. Non-HA granulomas are managed with intralesional steroids, 5-fluorouracil, or surgical excision depending on response and severity.
Granuloma Annulare
Granuloma annulare is a benign inflammatory skin condition characterized by ring-shaped dermal papules and plaques — most commonly appearing on the hands, feet, elbows, and ankles. It is not caused by a foreign body but by an immune-mediated palisading granulomatous reaction. Granuloma annulare can be localized, generalized, or associated with systemic conditions including diabetes and thyroid disease. Dr. Sierro evaluates granuloma annulare at Kare Plastic Surgery with dermoscopy and biopsy when indicated, and treats with topical or intralesional steroids.
Cutaneous Sarcoidosis
Sarcoidosis can manifest in the skin as non-caseating sarcoidal granulomas presenting as papules, plaques, subcutaneous nodules, or lupus pernio — indurated violaceous plaques on the nose, cheeks, and ears. Cutaneous sarcoidosis requires biopsy confirmation and systemic workup including chest imaging, pulmonary function testing, and ophthalmologic evaluation. Dr. Sierro performs biopsy and coordinates the full multidisciplinary workup for patients with suspected cutaneous sarcoidosis at Kare Plastic Surgery.
Tattoo Granuloma
Tattoo pigment — particularly red, purple, and yellow pigments — can trigger delayed granulomatous reactions within specific color areas of a tattoo, presenting as raised, indurated, or inflamed zones within the tattooed skin. Tattoo granulomas may be isolated or may represent a cutaneous manifestation of systemic sarcoidosis triggered by tattoo pigment. Biopsy is essential to distinguish between allergic tattoo granuloma and sarcoidal tattoo granuloma, as the management differs significantly between these two entities.
Infectious Granuloma
Certain bacterial, fungal, and mycobacterial infections produce granulomatous skin reactions — including Mycobacterium chelonae and Mycobacterium abscessus infections, which have been associated with contaminated cosmetic filler and mesotherapy products. Infectious granulomas require culture, sensitivity testing, and extended antibiotic therapy rather than steroid injection — which can worsen infectious granulomas significantly. Dr. Sierro's systematic biopsy approach ensures infectious granulomas are correctly identified before any treatment is initiated.
Dr. Sierro's Granuloma Diagnostic Treatment Approach at Kare Plastic Surgery
Dermoscopy & Clinical Evaluation
Every granuloma evaluation at Kare Plastic Surgery begins with a comprehensive clinical history — procedure type, material used, injection volume, time since treatment, and symptom progression — followed by dermoscopic examination of the lesion. Dermoscopy reveals vascular patterns, surface architecture, and pigmentary features that help Dr. Sierro narrow the differential diagnosis before biopsy. A detailed history of cosmetic procedures, medications, and systemic symptoms is essential context that many granuloma patients have not been asked to provide in prior consultations.
In-Office Biopsy with Histopathology
Skin biopsy is the diagnostic cornerstone of granuloma management at Kare Plastic Surgery. Dr. Sierro performs punch or excisional biopsy under local anesthesia — most commonly in the same consultation visit — and submits the specimen for hematoxylin and eosin staining, special stains for organisms (PAS, GMS, AFB, Fite), and polarized light microscopy for foreign material identification. The histopathological report from a board-certified dermatopathologist directs the entire subsequent treatment plan. Biopsy incisions are closed with minimally scarring fine suture technique.
Intralesional Injection Therapy
Inflammatory granulomas — including most dermal filler granulomas, granuloma annulare, and some silicone granulomas — respond to intralesional triamcinolone acetonide injection, administered in precisely calibrated concentrations to the center of the granulomatous tissue. Refractory cases may benefit from intralesional 5-fluorouracil either alone or in combination with steroids. Dr. Sierro tailors injection concentration and interval to each patient's response, monitoring for steroid atrophy and adjusting protocol accordingly. Hyaluronidase injection is added for confirmed HA filler granulomas.
Surgical Excision & Coordinated Care
Large silicone granulomas, permanent filler granulomas refractory to injection therapy, and granulomas causing significant cosmetic deformity or functional impairment are candidates for surgical excision. Dr. Sierro coordinates excision procedures with the board-certified plastic surgery team at Kare Plastic Surgery — ensuring that the excision is planned with optimal margin, tissue handling, and closure technique to minimize scarring and achieve the best possible cosmetic outcome. This integrated dermatology-plastic surgery approach is a defining feature of granuloma care at Kare Plastic Surgery.

Call (310) 998-5533. Located at 804 7th Street, Santa Monica, CA 90403.
What is a silicone granuloma and how is it treated?
A silicone granuloma is a chronic foreign body inflammatory reaction to injected silicone — forming firm nodules or plaques at or near the injection site, sometimes months or years after the original procedure. Biopsy reveals characteristic lipogranulomatous inflammation with vacuolar spaces surrounded by histiocytes and multinucleated giant cells. Treatment options include intralesional steroid injection for smaller lesions and surgical excision for larger or refractory granulomas. Dr. Sierro at Kare Plastic Surgery performs biopsy-confirmed diagnosis and comprehensive management. Call (310) 998-5533.
Can dermal filler cause a granuloma and how is it treated?
Yes. Any dermal filler — HA, CaHA, PLLA, or permanent — can trigger a delayed granulomatous reaction, typically presenting as firm nodules weeks to years after injection. Hyaluronic acid filler granulomas may respond to hyaluronidase. Non-HA granulomas are treated with intralesional steroid injection, 5-fluorouracil, or surgical excision for refractory cases. Dr. Sierro at Kare Plastic Surgery provides biopsy-confirmed diagnosis and individualized treatment. Call (310) 998-5533.
Why is a biopsy necessary to diagnose a granuloma?
Clinical examination cannot reliably distinguish between silicone granuloma, filler granuloma, infectious granuloma, cutaneous sarcoidosis, and other granulomatous conditions — each of which requires a different treatment approach. The histopathological pattern on biopsy is the only definitive method of confirming the granuloma type and directing treatment. Treating without a biopsy — particularly with steroids — risks significantly worsening an underlying infectious granuloma. Dr. Sierro performs in-office biopsies at Kare Plastic Surgery, most often during the same consultation visit. Call (310) 998-5533.
