Popis: Abstract Background Tumor lysis syndrome is an oncologic emergency that classically occurs following cancer therapy, although spontaneous tumor lysis syndrome can also occur in malignancies, albeit rarely. Spontaneous tumor lysis syndrome has previously been reported in some hematologic malignancies, but it rarely happens in solid tumors and seems to be associated with a higher mortality rate. This is the first case of adrenal adenocarcinoma that developed spontaneous tumor lysis syndrome. Case presentation We present a rare case of spontaneous tumor lysis syndrome occurring in a patient previously diagnosed with adrenal adenocarcinoma. The patient was a 64-year-old Persian man with abdominal pain, hypersomnia, and fatigue who was previously diagnosed with right adrenocortical carcinoma and had undergone right adrenalectomy with regional lymph nodes resection 5 months previously. On physical examination, the patient had abdominal distension and mild tenderness at the right upper quadrant. Pitting edema was detected bilaterally in the lower extremities. Initial imaging revealed multiple and large lesions suggestive of liver metastases. The laboratory data showed hyperkalemia, hyperuricemia, hyperphosphatemia, and elevated serum creatinine level indicative of spontaneous tumor lysis syndrome in the patient. Despite immediate and intensive care with antibiotics, hydration, treatment with a hypouricemic agent, and renal replacement therapy, the patient ultimately died from multiorgan failure. Conclusions Tumor lysis syndrome in solid tumors has high mortality. Patients susceptible to spontaneous tumor lysis syndrome must receive aggressive treatment immediately, which is crucial for preventing morbidity and mortality. Spontaneous tumor lysis syndrome may be underdiagnosed, and a high degree of clinical suspicion is needed to make the diagnosis and proceed with required interventions. Therefore, clinicians should be aware of this rare phenomenon.
