A 16-year-old girl presented with a high fever that had persisted for more than 4 weeks. Computed tomography revealed a 4-cm mass in the left adrenal gland. Clinically, there were no obvious symptoms of adrenal hormone excess; however, serum interleukin-6 (IL-6) and C-reactive protein levels were significantly elevated. After laparoscopic left adrenalectomy, the fever subsided, and her IL-6 level normalized. The tumor was pathologically diagnosed as adrenocortical carcinoma (ACC), with a Weiss score of 5/9. The tumor cells were immunoreactive for IL-6. To our knowledge, this is the first case report of symptomatic IL-6-producing ACC that initially presented with a persistent fever.

Introduction: Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis, limited treatment options, and high recurrence rates. Surgery and mitotane-based chemotherapy remain the standard of care, and new treatment strategies are needed. Iron oxide nanoparticles (IONPs) offer promise as theranostic agents due to their modifiability for selective uptake and imaging.

Background: Adrenocortical carcinoma (ACC) is a rare and highly aggressive malignancy, ranking as the second most aggressive endocrine tumor after anaplastic thyroid cancer. ACC typically presents symptoms caused by the tumor mass and less often with signs of excess hormones. Due to its rarity, the diagnosis and management of ACC pose significant challenges, with limited clinical guidelines, a lack of large-scale randomized studies, and a paucity of treatment experience.

Introduction: Pulmonary mucinous epithelioid carcinoma (PMEC) is a rare malignancy that typically progresses slowly and has a favorable prognosis. In contrast, adrenal sarcomatoid carcinoma (ASC) is an aggressive and uncommon cancer with poor outcomes. The coexistence of low-grade PMEC and metastatic ASC is exceedingly rare and presents unique clinical challenges, with limited treatment options and poor prognosis.

Oncocytic adrenocortical carcinoma (OACC) is a rare variant of adrenocortical carcinoma composed predominantly of oncocytic cells. We present the case of a 45-year-old female with a large, non-functional left adrenal mass diagnosed as OACC. Imaging revealed a well-defined, vascular, heterogeneously enhancing mass without metastasis.

Adrenocortical carcinoma is a rare, aggressive endocrine malignancy with limited effective systemic therapy options and an overall poor prognosis for unresectable or metastatic disease. Chemotherapy and mitotane are the traditional systemic therapies of choice. More recently, as drug development in oncology has shifted away from chemotherapy, a host of therapeutic approaches targeting novel mechanisms of action has been studied in adrenocortical carcinoma.
