Metastatic cutaneous carcinoma - Skin
Cutaneous metastases usually indicate a very poor prognosis, with patients often succumbing to their disease within 3-6 months. Patients may be any age but are typically older. The interval between detection of the primary tumor and development of cutaneous metastases may be on the order of years, or skin metastases may be the first manifestation of an internal malignancy.
In addition to the skin lesion(s), patients with previously undiagnosed cancer may also notice a palpable mass, pallor, or weight loss. A personal history of previous carcinoma provides an important diagnostic clue.
