Abstract
The most frequent reason for cutaneous metastases is breast cancer in females. Breast cancer patients can present with cutaneous manifestations of breast disease at the time of their initial diagnosis; however, cutaneous metastases more often present well after the initial diagnosis and treatment of the breast disease. We described three cases of carcinoma of breast metastasis to the skin of the breast and the chest wall, each with a unique dermatological presentation. A 52-year-old woman presented with a cutaneous erythematous papule for the past month. She underwent a modified radical mastectomy one year before. On presentation, she was diagnosed to have erythematous papule near the operative scar and surrounding chest wall and referred to the dermatology outdoor department, where a skin biopsy was done, which confirmed erysipeloides carcinoma. The second case includes a 38-year-old premenopausal lady who was diagnosed with carcinoma of the right breast with a locally advanced stage. She was treated with neoadjuvant chemotherapy (NACT) followed by modified radical mastectomy and subsequently presented with biopsy-proven multiple skin nodules on the chest wall at the same side. She was discussed in a multidisciplinary tumor board and planned for palliative chemotherapy followed by hormonal therapy. In the third case, a 42-year-old perimenopausal woman diagnosed with locally advanced left breast carcinoma presented in the surgical oncology outdoor patient department (OPD) with multiple skin erythema over the left breast. Biopsy was done from the skin erythema site showing metastasis to the skin. She was discussed in a multidisciplinary tumor board and planned for systemic chemotherapy followed by assessment for surgery. Skin erythema and erythematous papules are rare manifestations of cutaneous metastasis in patients with carcinoma of the breast; typically, patients present with a chest wall nodule. Careful examination and early detection of these uncommon skin lesions can lower morbidity and slow the progression of diseases in these patients.
