Amyloid goiter: a case of primary thyroid amyloid disease

Amyloid goiter is an atypical presentation of an already rare disease, amyloidosis, which uncommonly comes across in previous review of literature. A patient presented with respiratory distress, which aroused a dilemma on diagnosis because the presentation mimicked that of malignancy. A high index of attentiveness should be kept whenever amyloid deposits are seen on fine needle aspiration cytology, as they are also established in medullary carcinoma. Amyloid deposits have been traced in goiter; however, it was astonishing to observe this condition causing a rapidly growing goiter, large enough to cause respiratory distress. The confirmative diagnosis rested on the histopathology of the specimen.
