Lymphomatosis cerebri (LC) is a rare variant of a primary central nervous system non-Hodgkin's lymphoma (PCNSL) characterised by diffuse infiltration of tumour cells throughout the brain parenchyma. We present a 68-year-old immunocompetent woman with headaches, dizziness, blurred vision, localised right leg weakness and rapidly progressive dementia. A brain MRI demonstrated diffuse T2 hyperintense white matter lesions that did not enhance with contrast. The clinical differential diagnosis of these lesions included metastatic disease, infectious or inflammatory process such as sarcoidosis, lymphoma, demyelinating disease and less likely vascular aetiology, such as vasculitis or ischaemic stroke. A right frontal stereotactic brain biopsy was non-diagnostic. The patient eventually died from aspiration pneumonia following a pneumonectomy for a primary lung adenocarcinoma. The diagnosis of LC was established on postmortem examination of the brain.

The non-Hodgkin's lymphoma is a significant malignant disease that can involve in the extranodal region of the head and neck. It does not show any specific symptoms when it resides in this region. Swelling, pain and ulceration are important clinical findings. In this article, we report a 57-year-old male patient diagnosed with B cell non-Hodgkin's lymphoma by histopathologic examination, who had nasal blockage, snoring and headache complaints for one year, whose endoscopic nasal examination revealed a mass arising from the right inferior turbinate and the mass was removed surgically by endoscopic approach.

The association between Rosai-Dorfman Disease (RDD) and cancer was reported for the first time in 1984. However, there are still a small number of reports of this association. We describe a 60-year-old woman who presented with a focal onset motor seizure followed by tonic-clonic generalization and persistent headache. Magnetic Resonance Imaging disclosed an irregular hyperintense lesion in T2 and vasogenic edema in the left parietal region. Immunohistochemical analysis of a biopsy fragment was positive for protein S-100 and CD68 and negative for CD1a, compatible with the diagnosis of RDD. She previously had breast cancer six years earlier and had used tamoxifen for two years and anostrozol for three years after diagnosis of cancer. RDD has been already associated with different cancers, such as Hodgkin's lymphoma, non-Hodgkin's lymphoma, follicular lymphoma, melanoma, adenocarcinoma and small cell lung cancer. As far as we know, this is the first report of an association between breast cancer and RDD.

A 68-year-old man, with a history of non-Hodgkin's lymphoma in remission, was admitted for homonymous hemianopsia, headaches and subacute progressive cognitive decline. Imaging revealed brain infarcts and angiography suggested vasculitis. A brain biopsy, however, revealed an intravascular large B-cell lymphoma (IVLBL). Central nervous system (CNS) vasculitis and IVLBL of the brain are extremely rare diseases that can have an almost identical clinical presentation. Angiographic findings are very similar but usually are reported as compatible with vasculitis. Brain biopsy or a random skin biopsy are crucial in diagnosing IVLBL as the accuracy of angiographic findings for CNS vasculitis is low.

Primary central nervous system lymphoma (PCNSL) is a rare form of extranodal non-Hodgkin's lymphoma and a limited number of cases have been reported from China. This study aimed to investigate the clinicopathological features of newly diagnosed PCNSLs from a single center in eastern China and to identify the potential prognostic factors for overall survival (OS) and progression-free survival (PFS). All consecutive patients with histopathologically diagnosed PCNSLs at our center between January 2003 and October 2017 were recruited. Demographic and clinicopathological data were collected and reviewed retrospectively. The potential risk factors for OS and PFS were identified using the log-rank test and Cox regression analysis. A total of 167 immunocompetent cases were enrolled. The median age was 58 years (range 17-96 years), and the male:female ratio was 3:2. Headache (n = 65; 39%) and cerebral hemisphere (n = 96; 57%) were the most common presenting complaint and location, respectively. Out of 167 cases, 150 cases were diffuse large B cell lymphomas. With a median follow-up of 25 months (range 1-152 ), the median OS and PFS were 37 months (95% CI, 25-49) and 17 months (95% CI, 13-20), respectively. Residual tumor after operation, chemotherapy without HD-MTX and palliative treatment was revealed as independent prognostic markers. Moreover, ECOG > 3, multifocal lesions, and palliative treatment were revealed as unfavorable independent prognostic markers for PFS. In conclusion, Chinese patients with PCNSL have distinct characteristics. Further studies are warranted to confirm the prognostic value of these factors and to optimize treatments for these patients.
