Description
Summary:Background/Aim: Primary small cell neuroendocrine carcinoma (SCNEC) of the adrenal gland is extremely rare with limited reports in the literature. There remain no definitive treatment guidelines, largely due to the rarity of the malignancy. Case Report: We present the case of a 62-year-old Caucasian male who presented with low back pain and was found to have a large retroperitoneal mass arising from the left adrenal gland, measuring 18.3 × 12.2 centimeters (cm). Biopsy was consistent with small cell carcinoma/high grade neuroendocrine carcinoma. Staging workup including CT chest and bone scan was negative. The patient was treated with chemotherapy, radiation therapy, and surgery; complete pathological response of the left adrenal tumor was achieved. Surveillance imaging every three months continued to show no evidence of recurrent disease. Conclusion: Primary SCNEC of the adrenal gland is rare and lacks standard treatment guidelines. Our case represents a possible treatment approach that may provide better clinical outcomes, however, further investigations are necessary to help define ideal treatment guidelines.
