Laboratory tests revealed a decrease in white blood cells (WBC), red blood cells (RBC), and platelet count (PLT). Bone marrow aspiration revealed an extremely low degree of hyperplasia of hematopoietic cells. Simultaneously, the levels of thyroglobulin antibodies and thyroid peroxidase antibodies were significantly elevated. Neck ultrasound findings revealed nodules in both lobes of the thyroid. Moreover, fine-needle aspiration biopsy indicated the atypical presence of proliferative thyroid epithelial cells. Even after implementing various treatments hematopoietic function could not be restored. However, following a surgery, the patient\u2019s WBC, RBC, and platelet counts gradually returned to normal.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Here, we
