  • Title: Clinicopathological correlation of cutaneous metastatic breast carcinoma using lymphatic and vascular markers: lymphatics are mainly involved in cutaneous metastasis.

    Abstract:
    Precise clinicopathological correlations of the clinical features of metastatic breast carcinoma with lymphatic-specific markers are rare. We classified 28 patients with metastatic breast carcinoma according to their clinical features. Immunohistochemical staining was performed using D2-40, CD31 and CD34. Of the 28 patients, 8 (28.6%) had inflammatory metastatic carcinoma, 6 (21.4%) had the telangiectatic type, 5 had the nodular type, 3 had the en cuirasse type, 3 had alopecia neoplastica, and 3 had a combination of features. D2-40 staining revealed dilated lymphatic channels (lymphangiectasia) in the upper dermis of all patients; in addition, 13 patients (46.4%) had intralymphatic tumour-cell emboli, which were common in those with the inflammatory and telangiectatic types. Intratumoral lymphatic invasion in the main tumour nodule was seen in 12 patients (42.9%). Our results suggest that cutaneous metastatic breast carcinomas have various clinical presentations, and that lymphatic vessels play an important role in all types of cutaneous metastasis.
