Rt: 2.0x1.0cm sized ill defined low echoic lesion, 0.4cm sized isoechoic nodule Lt: diffuse heterogeneous echogenicity, 1.3x1.3cm sized low echoic lesion multiple lymph node at bilateral level VI No suspicious lymph node on bilateral lateral neck 검사실 소견 CRP; 30.4mg/L (0.1~6.0) TSH receptor Ab; 1.24 IU/L (0~1.75) T3; ng/dL (71~161) Free T4; 2.0 ng/dL (0.8~1.7) TSH;<0.01 mIU/mL (0.86~4.69) Anti-TPO Ab; 19.5 IU/mL (5~13.6) Anti-thyroglobulin Ab; 18.4 IU/mL (10~124.2)

3 Cellular smear

4 염증세포가 background에 흩뿌려져 있고 핵이 주변 염증세포보다 큰 세포들이 모여 있는 것이 콜로이드와 함께 관찰되었습니다.크

5 콜로이드와 follicular cell과 epitheliod histiocyte가 loose granuloma를 형성하고 있습니다.

6 follicular cell과 epitheliod histiocyte가 loose granuloma를 형성

7 Multinuleated giant cell
핵은 uniform하고 small round to oval sharp nuclear membrane finely granular chromain 하나정도의 micronucleoli Cytoplasm을 abundant granular. 올라와 있는 사진 끝

17 Thin prep 에서는 background의 염증세포는 많이 관찰되지 않았습니다.
Follicular cell들이 약간 핵이 커져 있고 nucleoli가 보이는 activated Follcular cell들이 sheet 형태로 관찰되었습니다.

18 여러 개의 multinucleated giant cell이 관찰되었습니다.

19 Histologic findings Cellular smear
Multinucleated giant cell around colloid Aggregation of epithelioid histiocytes Sheets of mildly atypical follicular cells No oncocytic cells A few colloid Some lymphocytes and histiocytes Few neutrophils and no plasma cells A few spindle stromal cells

20 Multinuclear giant cells in thyroid FNA
Nodular goiter or Thyroid neoplasm with cystic change (Foreign body histiocytic type) Variable in size Nuclei uniform and usually small in numbers Cytoplasm dirt, granular, ± hemosiderin Subacute thyroiditis (Multinucleated foreign body type) May be present in large numbers Enourmous in size with multiple, uniform nuclei in tens and hundreds Often seen in the vicinity of blobs of colloid, forming granulomas ± epithelioid cells Spindle shaped stromal cells Hashimoto’s thyroiditis (Multinuleated giant cell) Infrequent occurrence Nondescript morphology Fewer nuclei Associated Hashimoto’s features Palpation thyroiditis Acellular smear, rare chronic inflammatory cells Colloid follicular cells are usually absent

21 Multinuclear giant cells in thyroid FNA
Papillary carcinoma (Multinucleated giant cell) Variable in size Anaplastic carcinoma P/D metastatic carcinoma Bizarre nuclei with malignant criteria Infectious granulomatous lesions/ Sarcoidosis (Multinucleated foreign-body giant cells) Langhans-type giant cells and necrotic acellular debris characteristic in tuberculosis granulomas (AFB stain +) Associated with epitheliod cells and granulomas Inadvertent aspiration of thyroid or thyroid cartilage (Megakaryocytes) Multilobulated nuclei Smudgy chromatin Abundant dense cytoplasm Other hematopoietc cells in background Hodgkin’s lymphoma (RS cell) Varying sized, large to giant forms, mirror-image nuclei or multinucleated with prominent nucleoli

22 conventional

23 Hashimoto’s VS Subacute
Abundant mixed lymphocyte and plasma cells Germinal center cells Lymphohistiocytic aggregates Hurthle cells and variable nuclear atypia Infrequent multinucleated giant cell / absent granulomas Little colloid Many multinucleated giant cell (numerous nuclei), often in the vicinity of blobs of colloid Mixed inflmmatory cells including epitheliod histiocytes and lymphocytes Hypocellular smear: scant follicular cell Degenerative changes in follicular cells, cell debris and colloid

24 Hashimoto’s VS Subacute
Pain over the thyroidal bed was recorded in 100% of subacute thyroiditis. Typical cases of Hashimoto’s disease do not present pain over the thyroidal bed. Cytologic findings of the final stages of the two condition may overlap: very small numbers of lymphocytes and oncocytic cells Fine-needle aspiration of subacute granulomatous thyroiditis (De Quervain's thyroiditis) : a clinico-cytologic review of 36 cases. Diagn Cytopathol Mar;16(3):

25 Hashimoto’s disease Subacute thyroiditis

30 DIAGNOSIS Some multinucleated giant cells, epthelioid histiocytes aggregation, and mildly aypical follicular cells in the background of lymphocytes and a few colloid (s.n) Note) 임상적으로 pain이 있다면 subacute thyroiditis의 가능성이 높습니다.
