granulocytic sarcoma (gs) is an unusual extramedullary tumor composed of immature granulocytic precursor cells. the intraoral occurrence of this tumor is extremely rare. here we report a case of gs with palatal swelling, gingival lesions in maxilla and mandible and aleukemic presentation in a 45 years old man.

This report describes a case of gastric plasmacytoma which was diagnosed following an episode of haematemesis and melaena. The patient had a previous orbital plasmacytoma and subsequently developed aggressive disseminated disease with extensive skin and subcutaneous deposits but without marked marrow involvement until the terminal phase. Following the episode of haematemesis and melaena, endosc...

INTRODUCTION Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone--solitary osseous plasmacytoma, or in soft tissue--extramedullary plasmacytoma (EMP). EMP represents less than 1% of all head and neck malignancies. CASE REPORT We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive...

A 25-year-old man presented with subacute onset paraparesis with sphincter disturbance. His past medical history unvealed b-thalassemia intermedia (compound heterozygote IVS 1-5) and hereditary persistence of fetal hemoglobin type 2. His neurological examination disclosed a complete spinal cord syndrome without clear thoracic sensory level. Spinal cord imaging showed severe thoracic spinal sten...

Immunologic and histologic studies were performed in 10 cases of myeloma that showed progression to a more aggressive proliferation, designated as immunoblastic sarcoma of B-cell type (B-IBS). Several patterns of clinical presentation were observed: eight patients showed typical multiple myeloma, four developed B-IBS within the bone marrow, and four developed B-IBS in multiple extramedullary si...

A 56-year-old woman was referred to our hospital with a growing gastric submucosal tumor. An upper endoscopic examination revealed two gastric tumors, an original polypoid tumor and a newly diagnosed superficial tumor. Boring biopsied specimens of the submucosal tumor showed gastric plasmacytoma; however, the other specimens showed no malignancy. Blood diseases were ruled out using various exam...

A 24-year-old man with tuberculosis meningitis developed acute paraplegia and sensory disturbances 5 weeks after receiving conventional antituberculous therapy. Magnetic resonance imaging revealed an intradural extramedullary long segmental mass mimicking en plaque meningioma at the T2-T6 vertebrae levels. Prompt surgical decompression was performed. A histology examination of the mass revealed...
