Lymphomatoid Granulomatosis*

We report a case of cerebral lymphomatoid granulomatosis in a 50-year-old man. Lymphomatoid granulomatosis is an unusual condition which usually presents as a pulmonary manifestation, which occasionally affects the brain, and causes focal inflammatory lesions. Primary cerebral lymphomatoid granulomatosis is very rare. We describe a case of lymphomatoid granulomatosis in the left frontal lobe without pulmonary involvement.

We describe a patient with cutaneous angiocentric immunoproliferative lesion (AIL) associated with the Epstein-Barr virus (EBV). An organ system survey revealed no evidence of internal involvement. A skin biopsy specimen .showed infiltrating cells involving mainly deeper dermis and subcutaneous tissue. An examination of the reticular dermis revealed polymorphous angiocentric and angioinvasive infiltrate containing some atypical lymphocytes and histiocytes. EBV encoded RNA (EBER) was demonstrated in lesional skin by the in situ hybridization technique. On the basis of these findings, we conclude that our case may represent a form of AIL associated with EBV showing histologic features of classical lymphomatoid granulomatosis.

We report a case of Lymphomatoid granulomatosis in a 54-year-old woman. She presented with a two months history of a tender nodule located on the left for earm associated with fever and pulmonary symptoma aggravated against various treatments. She died 92 days of admission because of respiratory failure. Diagnosis was based on the clinical features and histopathologic findings of the skin lesion.

Lymphomatoid granulomatosis usually presents as a primary lung affliction with secondary metastatic spread to the central nervous system(CNS), and its initial manifestation purely as a CNS disease is rare. A 57-year-old man with histologically proven lymphomatoid granulomatosis of the brain as the sole manifestation of the disease is presented.

Lymphomatoid granulomatosis (LG) is a potentially malignant lymphoproliferative disorder. The lung is the most common involved site, followed by the skin and nervous system. However, LG of the central nervous system presenting with Parkinsonism is very rare. We report a patient with LG who presented with parkinsonian features such as bilateral rigidity, bradykinesia, and agitation. Brain magnetic resonance imaging showed multifocal punctuate enhanced lesions in both supra- and infratentorial areas. Steroid pulse therapy resulted in a dramatical improvement in the symptoms and MRI abnormalities.

Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

Lymphomatoid granulomatosis (LYG) is a lymphoproliferative disease involving the lungs most frequently; however, it may also involve the kidneys, skin and especially the central nervous system. Unique initial presentation of spinal involvement is extremely rare and epidural lesion of thoracic spine has not been reported. The prognosis for LYG has been reported to be poor, and there currently exists no satisfactory established treatment protocol. The purpose of this study is to report a case of successful treatment with surgery and rituximab combination therapy in thoracic spinal LYG.
