Introduction: Primary thyroid lymphomas (PTL) account for 5% of all thyroid malignancies. Treatment and prognosis depend on tumor subtype. Contrasting with diffuse large B-cell lymphomas (DLBCL), that have an aggressive clinical course and higher maximum standardized uptake value (SUVmax) in Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET), thyroid extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) usually show an indolen...

Introdution: Erdheim-Chester disease is a rare multisystemic form of Non-langerhans cell histiocytosis CD67 positive, with approximately 550 published cases. Papillary carcinoma is the most common thyroid cancer with BRAF V600E the most common mutation. Both diseases may be associated to BRAF V600E mutation. If Erdheim- Chester disease is positive to this mutation on histiocytes, a specific pharmacolgical treatment is available, (vemurafenib), with better results.<p class=...
