Langerhans cell histiocytosis of the thyroid

Langerhans histiocytosis is a disease with a very diverse clinical spectrum and a very varied prognosis. The thyroid localization is relatively rare, and raises diagnostic and therapeutic difficulties. Diagnosis often requires recourse to clinical, radiological and pathological confrontation. Combined medical and surgical treatment is indicated and requires close multidisciplinary cooperation. On the basis of a new observation and data in the literature, we present a progress report on the clinical and therapeutic options preferred by various authors.
