Resumen

PECANHA, Francilene M. et al. Pigmented cutaneous metastasis of breast carcinoma: florid case with zosteriform distribution. Port J Dermatol Venereol. [online]. 2024, vol.82, n.2, pp.126-129.  Epub 17-Abr-2024. ISSN 2795-501X.  https://doi.org/10.24875/pjdv.23000096.

This case report presents a rare manifestation of a pigmented cutaneous metastasis of breast carcinoma with a zosteriform distribution. A 77-year-old woman, previously diagnosed with invasive ductal carcinoma of the breast, exhibited pigmented lesions resembling shingles on the left thoracodorsal region. Dermoscopic and histopathological examinations confirmed invasive carcinoma of mammary origin associated with melanocytic colonization. The zosteriform pattern, though rare, has been reported in cases of cutaneous metastasis from breast cancer. Treatment options include addressing the primary tumor and direct approaches such as surgery or radiotherapy for skin lesions. This report highlights the importance of clinical suspicion, histopathological evaluation, and immunohistochemical examinations for accurate diagnosis, enabling timely and appropriate treatment for improved patient outcomes.
