Systemic argyria with severe anemia (hemoglobin 2.4 g/L)

Area of Science:

• Internal Medicine
• Toxicology
• Hematology

Background:

• Argyria is a rare condition caused by chronic silver exposure, leading to silver granule deposition and characteristic skin discoloration.
• It can mimic other conditions, necessitating careful diagnosis to differentiate from diseases like pseudocyanosis.
• Silver accumulation can also lead to secondary health issues, such as anemia.

Observation:

• A 68-year-old woman presented with severe anemia and generalized slate-gray skin discoloration.
• She reported a 7-year history of daily oral colloidal silver consumption.
• Hematologic tests revealed severe iron-deficiency anemia (hemoglobin 2.4 g/dL) with low ferritin.

Findings:

• The patient's symptoms and history were consistent with argyria secondary to colloidal silver intake.
• Iron-deficiency anemia was confirmed, with no evidence of copper deficiency or ceruloplasmin abnormalities.
• The skin discoloration was attributed to silver deposition, a hallmark of argyria.

Implications:

• This case underscores the critical importance of inquiring about and counseling patients regarding their use of nonprescription supplements.
• Accurate diagnosis is vital, as argyria can present with symptoms mimicking other serious conditions.
• Physicians should consider environmental and supplemental exposures when evaluating unexplained anemia and skin changes.
