Double Trouble – Synchronous Primary Malignant Neoplasms: A Case Report

Synchronous primary malignancy (SPM) is rare. We herein present a case of gastric carcinoma (GC) and renal cell carcinoma (RCC) to highlight the fact that the occurrence of RCC as a synchronous tumor along with GC is rare and that a high index of suspicion of SPM should be considered before declaring it as a metastasis. A 60-year-old male presented with abdominal pain and vomiting for 4 months, and a mass was incidentally found in the lumbar region. The patient was diagnosed with SPM of the GC and RCC. Chemotherapy was given, followed by total gastrectomy; radical nephrectomy was performed. The patient is currently on follow-up. Complete history taking and thorough physical examination of patients with malignancy is instrumental in ruling out metastasis and other synchronous lesions, especially in GC. Synchronous malignancies should be treated with the multidisciplinary team, as there is no consensus in the treatment protocol
