Ultrasound and Fine Needle Aspiration Cytology (FNAC) usually do not provide the diagnosis. Surgery is one of the treatment options because it enables histological diagnosis and can also relieve compression symptoms in patients with rapid growth cervical mass. We present 7 cases of PTL diagnosed in the last 10 years in our unit. Five were female (71.4%) and 2 were male (28.6%). The mean age was 64.2 (range: 40 - 81);4 patients (57.1%) had associated Hashimoto’s Thyroiditis (HT). One patient (14.2%) had concomitant Graves disease. 5 cases presented with compressive symptoms and cervical mass. Ultrasound was not diagnostic in any case. FNAC was diagnostic only in one patient (14.3%). Five patients underwent total thyroidectomy (71.4%). All the cases were diagnosed with lymphoma postoperatively. Two interventions consisted of left hemithyroidectomies (28.6%). No complications appeared. 5 patients (71.4%) were classified as Mucosa-Associated Lymphoid Tissue (MALT) lymphoma. We also observed 1 Follicular grade I lymphoma and 1 Burkitt case. When the extension study was done, 1 patient was at stage IIIE (14%), 2 at IIE (28.5%) and 4 at IE (57.14%). Rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) and Iphosphamide, ethoposide and high dose Cytarabine (IVAC) were the treatment scheme when chemotherapy was used (in three cases). Two cases were treated only with total thyroidectomy, and 2 with total thyroidectomy and rituximab, and the latter was MALT. Complete Remission (CR) was achieved in all patients in the first year. All are still alive and in CR. In our experience, PTL diagnose can be challenging before surgery. Although surgery is not the gold standard for treatment, when it is done, it should be curative in MALT lymphomas confined to the thyroid.展开更多
