Los linfomas primarios de tiroides representan menos del 5% de las neoplasias primarias con elevada asociación con la tiroiditis de Hashimoto y tiroiditis linfocítica. Son tipos histológicos más frecuentes el linfoma B difuso de células grandes y el linfoma B de la zona marginal tipo MALT. Se presenta el caso de una paciente de 46 años que acudió a consultorio por aumento de volumen en región anterior de cuello, asfixia y ronquera. Con el diagnóstico de linfoma tiroideo, la paciente fue sometida a tiroidectomía total. El informe anatomopatológico confirmó el diagnostico de linfoma B de la zona marginal tipo MALT asociado a tiroiditis de Hashimoto, con positividad por inmunohistoquímica para marcadores linfoides B CD20 y CD21.
Primary thyroid lymphomas represent less than 5% of primary tumors with high association with Hashimotos thyroiditis and lymphocytic thyroiditis. Most common histological types are diffuse large B-cell lymphoma and lymphoma of MALT type B marginal zone. The case of a 46 year old who came to office by increased volume in anterior neck, choking and hoarseness. With the diagnosis. Thyroid lymphoma . The patient underwent total thyroidectomy. The pathology report confirmed the diagnosis of B lymphoma marginal zone MALT associated with Hashimotos thyroiditis, with positivity by immunohistochemistry for B lymphoid markers CD20 and CD21.

We describe the case of a 54 year old woman seen with an esophageal mass diagnosed as a primary esophageal lymphoma. The main symptom was dysphagia of seven months duration. The treatment consisted in resection of the tumor, and reconstruction of the defect with a reversed pleural flap, followed by a chemotherapy regimen that consisted of five drugs, cyclophosphamid, prednisone, doxorubicin, rituximab and vincristine (R-CHOP). The patient developed an esophageal pleural fistula treated with pleural drainage and irrigation that closed in 45 days. Two and one half years later she is doing well and disease free.

Purpose: Burkitt's lymphoma is one of the fastest growing malignancies in the pediatric population. It is a high-grade B-cell non-Hodgkin's lymphoma with endemic, sporadic and human immunodeficiency-associated subtypes. The African, or endemic, variant usually involves the maxilla and other facial bones, while head and neck manifestations in sporadic Burkitt's lymphoma are rare. Case description: Two cases of oral manifestations of Burkitt's lymphoma are described on the right jaw in young patients, which had different clinical evolution and prognosis.
Objetivo: O linfoma de Burkitt é uma das mais importantes neoplasias de crescimento rápido na população pediatra. É um linfoma Não-Hodgkin primário de células B subdividido em endêmico, esporádico ou associado a imunodeficiência humana. O tipo africano (endêmico), quando em cabeça e pescoço, envolve geralmente os maxilares e outros ossos faciais, enquanto que o envolvimento facial da forma esporádica é bem raro. Descrição do caso: São descritos dois casos intra-bucais de linfomas de Burkitt envolvendo maxila direita em pacientes jovens, os quais apresentaram evolução clínica e prognósticos diferentes.

Los procesos malignos de tipo linfomatosos que afectan el riñon son infrecuentes, y por lo general lo comprometen como una expresión más de una enfermedad sistémica. Clínicamente pueden ser asintomáticos y presentar hematuria e insuficiencia renal progresiva. El tratamiento es el de su enfermedad de base; en algunas situaciones está indicada la nefrectomía. Se presenta el caso de un paciente de 83 años de edad, en el estudio de rutina por prostatismo se detecta masa ocupante renal derecha. Con diagnóstico de tumor de vía excretora se realiza nefroureterectomía. El estudio anatomopatógico diferedo informa linfoma de células B tipo Malt (tumor linfoide asociado a mucosa), de origen pielocalicial con infiltración renal. Se realizan consideraciones anatomipatológicas, clínicas, diagnósticas y tertapéuticas de este tipo de linfoma, así como revisión de la bibliografía
