Occult Breast Carcinoma Presenting as Scalp Metastasis

Breast cancer is the most common tumor among women, and approximately 6% of the patients have de novo metastatic breast cancer. Occult breast cancer accounts for only 0.1–0.8% of the cases and most commonly presents with axillary lymphadenopathy. Scalp metastases are rare and have been described as a sign of progression or widespread metastatic disease. Here, we describe a rare case of de novo metastatic breast cancer to the scalp as the single site of spread and without an identifiable primary breast tumor.
