Small-cell carcinoma of the lung with inguinal lymph node metastasis at initial presentation

Groin node metastases are predominantly seen in primary malignancies of infradiaphragmatic location. However, sparse cases of inguinal metastases from tumors above the diaphragm have been reported in the medical literature. Here, we report a case of small-cell carcinoma of the lung with metastatic inguinal lymph node at the initial presentation in a 57-year-old man. The case was diagnosed and managed congruously as per the stage of the disease, which was metastatic. However, the patient was died due to disease progression after 8 months of diagnosis. This case edifies to a clinical oncologist's knowledge that patients with commodious and disseminated malignancies of supradiaphragmatic location may present with lymph nodes in the inguinal region.
