== Clinical History==
45 year old woman who presented to her primary care physician with fever for 5 months (Tmax of 102F), night sweats, and neck pain. She stated that she had pain with swallowing and felt as though her heart was racing. She denies any other associated symptoms.
===Past Medical History===
No medical problems
===Procedures and Past Surgical History===
* Upper endoscopy
* Appendectomy
* Vaginal delivery
===Allergies and Medications===
* Allergy to penicillin (rash)
* Hydroxyzine
* Omeprazole
* Fenofenadine
===Physical Exam===
* Temperature: 98.5 F
* Blood Pressure: 90/60
* Heart Rate: 102bpm
* Weight: 43.27 kg
* Height: 62.5 inches
* Neck: Mild sub-maxillary and anterior cervical lymphadenopathy. In the left thyroid lobe a 1.0 x 0.5cm mass was palpated. This nodule was tender to touch and did not have any associated erythema.
* The remainder of the exam was within normal limits.
==Radiology==
===Ultrasound===
*Right lobe measured 4.5 x 1.5 x 1.3cm. Multiple nodules were identified in the right lobe and the largest measured 2.0 x 1.5 x 0.7cm.
*Left lobe measured 4.6 x 2.0 x 1.1cm. This lobe was largely replaced by a single nodule measuring 3.3 x 2.1 x 2.0cm.
===Management===
The patient is sent home with instructions to follow up in a week.
==Follow Up Appointment==
One week later the patient returns and complains of continued fever and night sweats.
===Lab Results===
* Free T4 2.62 mg/dL (normal range 0.62-1.57 mg/dL)
* TSH 0.035 mcIntUnits/mL (normal range 0.350-5.500 mcIntUnits/mL)
* Anti-TPO <63 units (normal is <100 units)
* An uptake scan is performed, and shows decreased uptake in the presence of hyperthyroidism. This is called consistent with subacute thyroiditis.
===Plan===
Repeat thyroid function tests and biopsy the large nodule in the left lobe with the labs normalize.

===Resident Questions===
* <spoiler text="Benign or malignant?">
These groups of cohesive spindled epithelioid cells are also known as granulomas. Granulomatous thyroiditis is a benign entity.
</spoiler>
* <spoiler text="With these cytologic findings what should be included in our differential diagnosis?">
When we see granulomas in a thyroid we should always think of an infectious process, sarcoidosis, Hashimoto's thyroiditis, palpation thyroiditis, and granulomatous thyroiditis. The other entity that you should think of when you see epithelioid giant cells is papillary thyroid carcinoma.

==Diagnosis==
===Cytology===
'''Benign aspirate, see comment'''.
'''COMMENT''':
'''There are non-necrotizing granulomas, benign follicular cells, macrophages, colloid, lymphocytes, and multinucleated giant cells; consistent with granulomatous thyroiditis'''.
==Case Discussion==
Granulomatous Thyroiditis is also known as deQuervain or subacute thyroiditis. It is a postviral syndrome. Usual presentation is in a young woman who has just gotten over a cold.
Patients present with painful thyroid, fever, fatigue, chills. Diagnosis is usually made clinically, therefore FNA biopsy is usually not performed. The disease is usually self-limiting.
If an aspirate is performed it may be scantly cellular due to pain and fibrosis. If material is gathered you may see non-caseating granulomas, colloid, chronic inflammation, and multinucleated giant cells.
