Xanthomas are well-circumscribed skin lesions that are commonly seen in patients with familial hypercholesterolemia (FH). The aim of this report is to present a rare case of multiple large tuberous and tendinous xanthomas. A 17-year-old female patient in this report presented with multiple asymptomatic and papulo-nodular masses in both sides of palms, elbows, buttocks, knees, and Achilles tendons. Surgical removal of the masses was carried out in combination with lipid-lowering therapy. A following up of 3 months showed all wounds were healing well, and no recurrence of masses was observed. Therefore, for patients with xanthomas related with familial hypercholesterolaemia, lipid-lowering therapy has reportedly reduced the size of masses, but surgical treatment may be essential for large xanthomas caused pain or limitation of daily activities.

The triad of diabetic ketoacidosis, hypertriglyceridemia, and acute pancreatitis is a rare presentation of diabetes mellitus type 2 in adults. We report a case of a 41-year-old male who presented at the emergency department with a sudden onset of severe abdominal pain. Diagnosis of diabetic ketoacidosis, hypertriglyceridemia, and acute pancreatitis was made. Triglyceride level was 6056 mg/dL and glycated hemoglobin was 12.6%. Vigorous fluid therapy and continuous infusion of insulin were started, but due to maintained symptoms, a single plasmapheresis session was performed, with significant clinical improvement. This case emphasizes the diagnostic challenges of the triad and highlights the potential role of plasmapheresis in rapidly reducing triglyceride levels.
