Subcutaneous metastasis from an atypical pulmonary carcinoid tumor

We report the case of a 71-year-old woman with a longstanding history of primary atypical pulmonary carcinoid tumor who presented with a new tender cutaneous nodule. Immunostaining of the nodule was consistent with metastatic atypical carcinoid tumor of the skin including positive staining for neuroendocrine markers chromogranin and synaptophysin. Dermatologists should consider cutaneous neuroendocrine metastasis when evaluating new nodules in patients with stable pulmonary carcinoid tumors or in those with concomitant concerning respiratory symptoms.
