Telangiectatic cutaneous metastasis from breast carcinoma

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.

Clinical, Pathological, and Molecular Features of Breast Carcinoma Cutaneous Metastasis

“…The telangiectatic pattern may appear as an erythematous patch with prominent telangiectasias or as a lymphangioma circumscriptum-like pseudovesicular lesion [ 32 ]. It is characterized by papules, plaques, or purpuric nodules, and it is often accompanied by pruritus [ 33 , 34 , 35 ]. Telangiectatic presentation occurs with an incidence of 8–11% among patients [ 15 , 17 ].…”
