AI Article Synopsis
- Pulmonary carcinoid tumors are rare neuroendocrine tumors that typically don’t spread to the skin.
- A case involving a 71-year-old woman revealed a new tender skin nodule linked to her previous primary atypical pulmonary carcinoid tumor.
- Immunostaining showed the skin nodule matched characteristics of metastatic atypical carcinoid tumor, suggesting skin metastasis in patients with existing carcinoid tumors may be overlooked.
Article Abstract
Pulmonary carcinoid tumors are uncommon neuroendocrine tumors that rarely metastasize to the skin. 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.
