A computerized tomography(CT) scan showed a mass in the bilateral lacrimal gland region, more significant in right eye. The patient underwent a lacrimal gland mass excision surgery and diagnosis of mantle cell lymphoma by histopathology..Immunochemistry for CD20, CD79 a, CD5, and Cyclin D1 was positive. She was recommended to the Shantou cancer hospital for chemotherapy.Conclusion:.Mantle cell lymphoma is a rare type of malignant lymphoma,.over expressing CD5 and cyclin D1 antigens,which distinguishes it from other B cell lymphomas.展开更多

We report the case of a 44-year-old man admitted for an anterior neck swelling, hoarseness and dyspnea. The chest radiograph showed a trachea deviation. He had no clinical, biological or radiological sign of other lymphoma locations. Ultrasound examination of the neck revealed a bilateral heterogeneous thyroid lesion. Cytology revealed lymphoid cells having high nuclear-cytoplasmic ratio with multiple and irregular nucleoli. An urgent thyroid surgery consisting of total thyroidectomy had been performed since the presence of compressive signs due to the tumor. The histopathological examination of a biopsy from the thyroid tissue confirmed a high-grade non-Hodgkin’s lymphoma. Then, L-thyroxin substitution therapy, chemotherapy and radiotherapy were initiated. A prolonged remission was noted.展开更多
