A case of solitary breast metastasis from malignant melanoma of the nasal cavity

Abstract

Abstract. Metastatic breast tumors are rare; however, malignant melanoma is one of the primary tumors most commonly reported to metastasize to the breast. Among these, the primary tumors typically associated with metastasis to the breast are cutaneous melanomas. We present, herein, a very rare case of solitary metastasis to the left breast from malignant melanoma of the nasal cavity, which represents less than 1% of all malignant melanomas. The patient, a 78-year-old woman, was treated using a combination of surgery and radiotherapy. In the absence of therapeutic efficacy, disease progression was very rapid. No previous studies have described malignant melanoma of the nasal cavity with solitary breast metastasis. This case report aims to increase awareness of the need to establish treatment strategies based on an understanding of the etiology and pathophysiology.

Microbial influences on hormesis, oncogenesis, and therapy: A review of the literature

“…There is also evidence that breast metastasis could be coming from malignant melanoma in the nose which makes S. aureus and many others, once more, viable culprits (Tanaka et al, 2012). Following this logic it may be rather easy to associate certain cancers with the bacteria that follow the same patterns of niche colonization.…”
