Cystic thyroid nodules are often benign, and ultrasound surveillance alone is regarded as a reasonable option for cystic nodules with a very low suspicion for malignancy. A Rare Case of Multifocal Papillary Thyroid Cancer in Bilateral Thyroid Cysts

These structures are critical for soil fertility as they enrich the soil with bioavailable nitrogen. Nodule formation is induced by signaling molecules called Nod factors produced by the symbiotic bacteria.
