Soft Tissue and Lower Limb Muscle Metastases from Breast Carcinoma: An Unreported Entity

Soft tissue metastasis from carcinoma breast is rare, and still rarer is metastasis to skeletal muscles. So far, soft tissue metastasis from breast carcinoma has been reported only in a small number of case series and case reports. To the best of our knowledge, no case of breast cancer metastasizing to the lower limb muscles has been reported. It is important to differentiate soft tissue metastasis from primary soft tissue malignancy, as the management and prognosis of these differ markedly. Here, we present a case of breast cancer metastasizing to the soft tissue at multiple sites including the right thigh muscles.
