A rare form of metastatic breast carcinoma mimicking lymphangioma circumscriptum.

Cutaneous metastasis is rare but may indicate an advanced internal malignancy or a recurrence of a previously treated one and is usually associated with a poor prognosis. They may also pose a diagnostic problem as the clinical manifestations are variable and non-specific, which could mimic other benign conditions. We report a case of a 48-year-old female who presented with a 4-year history of erythematous papules and vesicles on the trunk mimicking lymphangioma circumscriptum.
