We present the case of a 53-year-old woman with silicone breast implants who underwent excision of an abdominal melanoma and sentinel lymph node biopsy. Two lymph nodes were excised; both lying in the breast parenchyma adjacent to the intact right breast capsule. The lymph node histology revealed a subcapsular melanoma deposit along with silicone lymphadenopathy in the sentinel node. This case highlights that sentinel lymph nodes can be located in alternative locations to the common lymphatic basins and, therefore, the importance of preoperative lymphoscintigraphy. We also discuss subclinical breast implant rupture as a causative factor for silicone lymphadenopathy.
