Supraclavicular lymphadenopathy: an unexpected consequence of breast implant rupture.

Supraclavicular lymphadenopathy is a rare manifestation of silicone lymphadenopathy, a complication arising from breast implant rupture. We present a case of a 39-year-old woman with a history of bilateral breast augmentation using Poly Implant Prothèse implants who developed left breast swelling and progressive supraclavicular lymphadenopathy. Imaging revealed rupture of the left implant with silicone migration to supraclavicular lymph nodes, confirmed by the characteristic "snowstorm" sign on ultrasound. Surgical intervention involved bilateral implant removal and partial capsulectomy, with histopathological evaluation showing benign findings. Silicone lymphadenopathy, though typically associated with axillary nodes, can extend to cervical region posing diagnostic challenges. This case highlights the importance of considering silicone lymphadenopathy in patients with unexplained cervical lymphadenopathy and a history of breast implants. Diagnostic imaging and patient-centered management strategies remain crucial in addressing this rare but significant condition.
