Extensive silicone lymphadenopathy after breast implant insertion mimicking malignant lymphadenopathy

Silicone implants are widely used in aesthetic and reconstructive breast surgery. Silicone lymphadenopathy is a well-known rare complication of implant insertion. Silicone leakage from a rupture or silicone bleeding can accumulate in lymph nodes. Foreign body reactions in the affected lymph nodes may be misdiagnosed as metastasis or malignant lymphadenopathy upon initial presentation if silicone lymphadenopathy is not considered in the initial diagnosis. We report a case of siliconoma with extensive involvement of multiple Lymph nodes mimicking malignant features to emphasize that clinicians should carefully evaluate each patient's medical history and disease status during differential diagnosis.
