A Rare Case Report of Siliconoma in Contralateral Axillary Lymph Node After Silicone Implant Rupture

Breast reconstruction with silicone implants has become very popular after mastectomy in breast cancer patients. Rarely implants rupture and leak may spread to to ipsilateral axilla causing silicone lymphadenopathy. We present a rare case where silicone implant leak was complicated by axillary lymphadenopathy to the contralateral side. This rare phenomenon occurs due to the presence of aberrant lymphatic channels. Understanding the pathophysiology of this condition can enrich the discussion about contralateral axillary metastasis (CAM) in breast cancer, and if they should be considered a locally advanced disease rather than metastatic disease.
