Primary retroperitoneal serous cystadenoma (PRSC) is an extremely uncommon lesion of retroperitoneum. Very few case reports of this entity have been described in the literature. The pathogenesis is not well understood, although one of the proposed hypotheses considers it to be an embryological remnant of the urogenital apparatus with epithelial and mesothelial tissues. 1 These cysts oftentimes attain very large size before becoming symptomatic. Our case review is focused on the diagnostic, therapeutic, and pathological findings of this rare entity. Case PresentationA 79-year-old female presented to the emergency room with confusion, agitation, and visual hallucinations after sustaining a fall. Although the patient was a poor historian, her family members did not report prior history of abdominal complaints including trauma, fever, weight loss, abdominal mass, or surgery. Abdominal examination revealed soft, nontender, palpable fullness in the paraumbilical region. Gastroenterology service was consulted for a nontender AbstractPrimary retroperitoneal serous cystadenomas (PRSCs) are rare cystic lesions whose pathogenesis is currently not well understood. Although the vast majority of tumors are benign, early recognition and resection is necessary to avoid malignant transformation, rupture, and secondary infection. Here we present the case of a 79-year-old woman who presented with confusion, visual hallucinations, and a history of fall. As part of the work-up for abdominal distension, computed tomography scan of the abdomen and pelvis was performed, which revealed a right-sided retroperitoneal cystic lesion measuring 26.6 Â 16.7 cm in size. The lesion was resected laparoscopically, and the surgical specimen measured 28 Â 17 cm. Histology revealed a serous cystadenoma. The postsurgical course was uneventful, and no radiological recurrence was noted on 3 months follow-up. Very few primary retroperitoneal cystic lesions have been reported in the literature. Most lesions are benign and predominantly occur in females. They may remain asymptomatic for long periods of time and are usually discovered when they reach very large in size. In rare cases, these lesions may have malignant potential. Diagnosis of PRSC should be considered in the differential diagnosis of all retroperitoneal cysts.

The use of herbal and dietary supplements is rising in the United States. Turmeric has been one of the most popular supplements recently, used widely for various conditions such as arthritis, digestive disorder, and liver conditions. Although rarely reported, hepatotoxicity can happen with turmeric use. Here, we present 2 cases of drug-induced liver injury due to turmeric use with the complete resolution after cessation.
