In this article, we reported a case of primary non Hodgkin's lymphoma of the lacrimal sac presented with recurrent acute dacryocystitis in a young lady. A 28 years old Malay lady had history of persistent epiphora on left eye for 4 years. Prior to presentation to our clinic, it was preceded by progressive recurrent painful medial canthal swelling for 6 months duration. Clinical diagnosis of post saccal naso lacrimal duct obstruction was made and otorhinolaryngology assessment revealed intranasal mass. Endoscopic excision was done showed diffuse large B cell lymphoma on histology. The patient was started on 6 cycles of chemotherapy which subsequently result in no recurrence of the tumour post chemotherapy. Any case of post saccal nasolacrimal duct obstruction should be investigated thoroughly as it may become as a presentation of other sinister pathology.展开更多

Three cases of P53 gene point mutation was found in 29 cases of NHL. Mutation developed in exon 5 in 2 cases, and in exon 6 in 1 case. They were all diffuse lymphoma. In mutation cases, B cell lymphoma accounted for 2 cases and the other one was T cell lymphoma. There was no P53 gene mutation in low grade follicular lymphoma. Seven strains out of 9 kinds of lymphoma cell lines had P53 gene point mutation. One strain had the mutation in exon 5; 5 strains in exon 6 and 1 strain in exons 5, 6, 7. There was a high mutation rate in lymphoma cell lines and low mutation rate in NHL patients. P53 gene plays an important role in lymphoma cell line establishment, cell regeneration and disease evolution.展开更多
