Mercury Granuloma
A mercury granuloma is a type of granuloma that forms in response to the presence of mercury in the tissues. Granulomas are small areas of inflammation caused by a collection of immune cells known as macrophages. These cells attempt to wall off substances that they perceive as foreign but are unable to eliminate.
Pathophysiology
Mercury granulomas occur when mercury, often from amalgam dental fillings or other sources, becomes embedded in the skin or other tissues. The body recognizes the mercury as a foreign substance and mounts an immune response. This response involves the aggregation of macrophages and other immune cells, forming a granuloma.
Clinical Presentation
Patients with mercury granulomas may present with localized skin lesions that are often firm and nodular. These lesions can be painful or itchy and may vary in color from red to purple. The skin overlying the granuloma may become ulcerated in some cases.
Diagnosis
The diagnosis of mercury granuloma is typically made based on the clinical appearance of the lesions and the patient's history of exposure to mercury. A biopsy of the lesion can confirm the diagnosis by revealing the characteristic granulomatous inflammation and the presence of mercury deposits.
Treatment
Treatment of mercury granulomas involves the removal of the source of mercury exposure, if possible. Surgical excision of the granuloma may be necessary in some cases. Topical or systemic corticosteroids may be used to reduce inflammation and alleviate symptoms.
Prevention
Preventing mercury granulomas involves minimizing exposure to mercury. This can include using alternative materials for dental fillings and taking precautions when handling mercury-containing substances.
