Langerhans cell histiocytosis (LCH) is a rare myeloid neoplasm characterized by the proliferation of CD1a+/Langerin+ histiocytic cells. The incidence in adults is 1 to 2 cases per million, a little more frequent in children. The presentation is variable, as a single lesion in an organ to a multisystemic disease with touch of vital organs. The tissues with the highest affinity are: bones, skin, lungs and pituitary and rarely thyroid. Delay in the diagnosis or in the treatment can cause a deterioration in the function of the affected organs. The objective of the communication is to report a case of LCH, with an even less frequent presentation, isolated form in the thyroid gland of an adult, a finding made after a total thyroidectomy, the diagnosis being made after histology.
