Three Cases of Cutaneous Metastatic Carcinoma from Internal Malignancy

ABSTRACT

Cutaneous metastases from internal malignancy are relatively rare. Three cases of cutaneous metastases, two from lung cancer and one from breast cancer are reported. Case 1-cutaneous metastasis from bronchioloalveolar carcinoma of the lung, where four erythematous to pinkish pea sized smooth surfaced nodules on the scalp were noticed for 2 years in a 48-year-old man. Case 2-cutaneous metastasis from adenocarcmoma of the lung, where two hard tender freely movable subcutaneous nodules, about 3 cm in diameter on the lateral chest wall were noticed for 6 months in a 61-year-old woman. Case 3-cutaneous metastasis from infiltrating ductal carcinoma of the right breast, where a hand, violaceous, non-tender plaque (8×6.5 cm) on the right areolar area was noticed for 4 months in a 47-year-old woman.
