Case report: Management of infiltrative basosquamous carcinoma of the sternum.

Introduction And Importance: Basosquamous carcinoma (BSC) is a rare cutaneous cancer defined as a basal-cell carcinoma that has differentiated into a squamous-cell carcinoma. It is aggressive and infiltrative, and known for its multiple recurrences and risk for metastasis.

Case Presentation: This article describes the case of a 78-year-old man who presented with a several-year history of an infiltrative BSC of his chest-wall invading into his sternum.

Clinical Discussion: He was subsequently treated surgically with a chest-wall wide-local excision and sub-total sternectomy, reconstructed with titanium plates and a musculocutaneous anterolateral thigh free-flap.

Conclusion: This case highlights a surgical approach to advanced chest-wall BSC.
