Abstract
Cutaneous metastasis from breast cancer has varied clinical presentations. Herein, we present the case of a middle-aged female with a large erythematous patch and an itchy bluish-red papular eruption on the left side of the breast. The patient had a history of ductal breast carcinoma at age 40. Histology from one of the red papules revealed an atrophic epidermis and emboli of carcinomatous cells in the dermal and subcutaneous blood vessels. The morphology of the tumor cells was similar to that of the primary ductal carcinoma of the breast. The diagnosis of telangiectatic metastatic breast cancer was reached.
Highlights
Breast cancer is the most common cause of cutaneous metastasis in women
The patient was successfully treated by mastectomy and axillary lymph node clearance followed by adjuvant chemotherapy and local radiotherapy for infiltrating stage IIIB ductal breast carcinoma
Telangiectatic carcinoma with angiokeratoma-like lesions is a rarity in clinical practice and may be overlooked
Summary
Breast cancer is the most common cause of cutaneous metastasis in women. Considering the medical history, cutaneous breast carcinoma metastasis was suspected. A skin biopsy obtained from one of the red papules revealed an atrophic epidermis and emboli of carcinomatous cells in the dermal and subcutaneous blood vessels (Fig. 2a). A 42-year-old female presented herself to our department with a three-month history of a large erythematous patch and an itchy bluish-red papular eruption on the left side of the breast. The patient was successfully treated by mastectomy and axillary lymph node clearance followed by adjuvant chemotherapy and local radiotherapy for infiltrating stage IIIB ductal breast carcinoma. The patient passed away while on the chemotherapy, five months after the initial diagnosis of cutaneous metastasis
