Acute suppurative thyroiditis presenting as a painless thyroid swelling

Acute suppurative thyroiditis is a rare disorder. We saw a 24 year old man with this condition that present atypically. The patient had a non-tender thyroid enlargement associated with fever and leukocytosis. FNA cytology clinched the diagnosis. The abscess was associated with Klebsiella pneumoniae septicemia and required surgical drainage after failing antibiotic therapy.
