Recurrent Hypoglycemia in a Non-diabetic Female: A Case Study on Doege-Potter Syndrome.

Solitary fibrous tumors (SFT) are mesenchymal cell tumors that may arise from any site throughout the body. A small percentage of patients with SFT develop non-islet cell tumor-induced hypoglycemia (NICTH), eponymously termed Doege-Potter Syndrome (DPS). DPS is characterized by severe, refractory hypoinsulinemic hypoglycemia. Diagnosis of SFT is dependent on histologic findings and immunohistochemistry (IHC). NAB2-STAT6 gene fusions are pathognomonic for SFT but may be difficult to identify in routine cytogenetic studies. STAT6 IHC is a highly sensitive and specific surrogate for the NAB2-STAT6 gene fusion. Total resection of the tumor remains the gold-standard definitive treatment of SFT of the pleura. Palliative tumor debulking is recommended if total resection is not feasible. We here report a case of DPS in a 73-year-old female, managed with palliative care.

Relapse of Graves' disease following SARS-CoV-2 infection: A case report and brief literature review.

The interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and autoimmune thyroid disease is an emerging phenomenon. The present study describes the case of a 28-year-old female who experienced a relapse of Graves' disease following SARS-CoV-2 infection. She was biochemically euthyroid for 2 years prior to COVID-19 infection. However, she began experiencing palpitations, increased sweating and tremors of the hands 9 days after being diagnosed with COVID-19-related pneumonia. In addition to presenting this case, a comparison is made of this case to similar reports and the possible mechanisms underlying the association between SARS-CoV-2 and Graves' disease are discussed. One is a direct result of viral uptake by thyroid cells, while another is a result of the hyperinflammatory 'cytokine storm' and its effects on the hypothalamic-pituitary-thyroid axis and T-cell immunity.

Incomplete Kawasaki Disease in an Adult South Asian Patient.

Kawasaki disease is an acute multisystemic vasculitis occurring predominantly in children and rarely in adults, with sequelae of potentially life-threatening coronary artery aneurysms. "Incomplete" Kawasaki disease is a novel concept and considered a diagnosis of exclusion as it alludes to patients with fever lasting ⩾5 days and 2 or 3 clinical criteria without another reasonable explanation for the illness. The multidisciplinary team should be vigilant for this oligosymptomatic clinical presentation, specifically within this subgroup despite age and ethnicity, and the syndrome should be considered as a differential diagnosis in challenging cases presenting as infectious or autoimmune disease.
