    FNA of thyroid: polygonal tumor cells and amyloid

    Advertisements



    During a pre-employment physical, a 45-year-old man is noted to have a 3 cm palpable nodule in one lobe of an otherwise normal sized thyroid gland.
    Needle aspiration of the nodule demonstrates polygonal tumor cells and
    amyloid, but only very scanty colloid and normal follicular cells
    . Which of the following is the most likely diagnosis?

    A. Follicular thyroid carcinoma
    B. Hashimoto's disease
    C. Medullary thyroid carcinoma
    D. Papillary thyroid carcinoma
    E. Thyroid adenoma

    C. The giveaway here is "amyloid deposits" which arise from calcitonin, which comes from C cells of the thryoid. C cell hyperplasia is consistent with medullary carcinoma
    I used to pray and pray for a bike and never got one. Later I learned that God doesn't work that way... so I went out and stole a bike and asked God for forgiveness.
