Metastatic Extrapulmonary Small Cell Carcinoma Presenting as Obstructive Jaundice

Extrapulmonary small cell carcinoma (EPSCC) is a rare cancer with a poor prognosis. It can arise from almost any site and is usually associated with extensive metastasis at the time of diagnosis. Due to the rarity of this cancer, very limited data is available in the literature and most of the recommendations for its evaluation and treatment are based on retrospective studies and expert opinion. This case report shares one such presentation of EPSCC. A 78-year-old male was admitted to the hospital with presenting symptoms of abdominal pain and discoloration of the eyes and urine for 2 months. Initial laboratory investigation revealed obstructive jaundice and leukocytosis. His infectious workup was negative. An ultrasound abdomen was performed, showing multiple liver deposits. He received a computed tomography chest, abdomen, and pelvis with contrast also showing multiple liver deposits highly indicative of metastatic disease. No other obvious abnormality or mass in other visceral organs was reported. He underwent endoscopy and endoscopic retrograde cholangiopancreatography, showing normal pancreatic-biliary ducts. A plastic stent was deployed to help with biliary drainage. A liver biopsy was performed and showed poorly differentiated small cell carcinoma of extrapulmonary origin. His abdominal pain improved after stent placement; however, liver tests continued to worsen. During his hospital stay, he was seen by oncology and given metastatic disease; he was offered palliative ...
