A case of spontaneous tumor lysis syndrome in an adolescent with abdominal pain.

Tumor lysis syndrome (TLS) is an acutely life threatening, must-not miss, oncological emergency that infrequently presents to the emergency department (ED). This diagnosis is typically a complication of chemotherapy, however, TLS can also occur spontaneously as the first presentation of malignancy. This case discusses the rare presentation of an otherwise healthy adolescent male who presented to the ED with abdominal pain and lethargy and was subsequently found to be in acute renal failure and pancytopenic with the associated lab derangements of hyperkalemia, hyperphosphatemia, and hypocalcemia.

Lactation ketoacidosis induced by breastfeeding while on a ketogenic diet.

Lactation ketoacidosis is a very rare cause of metabolic acidosis in breastfeeding patients. We present a case of a 34-year-old female, 8-weeks postpartum, who was breastfeeding while also on the ketogenic diet. She developed dyspnea, chest pain, nausea, vomiting, and an inability to tolerate oral intake for several days.
