Pancytopenia, Cholestatic Jaundice, and Pulmonary Hypertension: Rare Extrathyroidal Manifestations of Graves' Disease.

Pancytopenia, cholestatic jaundice, and pulmonary hypertension are rare but serious complications of thyrotoxicosis. It is uncommonly seen in patients with hyperthyroidism and may result in treatment-related dilemmas as bone marrow suppression and drug-induced liver injury are known complications of anti-thyroid treatment.  We describe a case of Graves' disease presenting with all three manifestations of pancytopenia, cholestatic jaundice, and pulmonary hypertension during a relapse of thyrotoxicosis.

New-onset Thyroid Eye Disease after COVID-19 Vaccination in a Radioactive Iodine-Treated Graves' Disease Patient: A Case Report and Literature Review.

Autoimmunity associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been well-described as the mechanism of development of thyroid dysfunction following Coronavirus Disease 19 (COVID-19) infection and SARS-CoV-2 vaccination. However, the occurrence of thyroid eye disease (TED) after SARS-CoV-2 vaccination is scarcely described. The postulated mechanisms include immune reactivation, molecular mimicry and the autoimmune/inflammatory syndrome induced by adjuvants (ASIA).

Lessons of the month 1: A diagnostic dilemma: thyroid abscess or subacute thyroiditis?

Thyroid abscess is rare but potentially fatal, whereas subclinical thyroiditis is a self-limiting condition that is more commonly seen. The clinical features of both diseases can be overlapping but the treatment approach differs. We report a case of a painful left thyroid nodule not responding to conventional therapy for thyroiditis or thyroid abscess.
