Plasmacytoma of the calvarium is very rare, accounting for the 0.7 % of all plasmacytomas [1–5]. The most common locations are the thoracic and lumbar spine (30–40 % of cases). Involvement of the hip, femurs, and ribs is less frequent [6]. Plasmacytoma of the calvarium can be indistinguishable from other lytic lesions, especially metastatic disease. Meningioma, eosinophilic granuloma, and dermo...

Introduction: Plasmacytoma is monoclonal neoplastic proliferation of plasma cells. It can be either solitary or multiple and skeletal or extraskeletal. Solitary plasmacytoma is most frequently seen in vertebrae and secondarily in long bones. Its presence in jaws is extremely rare. Case Report: Here we report a case of plasmacytoma in the right side of mandible, a chronology for diagnosis of the...

We report here on a 64-year-old woman with extramedullary plasmacytoma involving the bilateral adrenal glands. Primary adrenal extramedullary plasmacytoma is extremely rare and only three cases of extramedullary plasmacytoma in the unilateral adrenal gland have currently been reported on. This case is of interest in that the bilateral adrenals were involved. In this article, we present the MRI ...

plasmacytoma are extramedullary accumulations of plasma cells. most extramedullary plasmacytomas are associated with the upper respiratory tract. the lung is rarely involved. we report a rare case of lung plasmacytoma with multiple myeloma. the patient is a 60-year-old male who presented with chest pain and a lung mass visualized on ct scan. a preliminary diagnosis of occult lung cancer with wi...

Extramedullary plasmacytoma is a rare cause of nonobstructive colonic masses, which is often disregarded. Plasmacytoma is a neoplastic proliferation of plasma cells; when systemic involvement occurs, the disease is named multiple myeloma. Extramedullary plasmacytomas comprise 4% of all plasma cell tumours and occur mainly in the upper respiratory tract; gastrointestinal system involvement is ra...

A case is reported of a patient with plasmacytoma which assumed different clinicopathological features over seven years. The tumour first presented as a subcutaneous mass which was misdiagnosed as anaplastic carcinoma. Complete response to radiotherapy ensued but recurrence took the form of an intracerebral tumour. Further complete response to "palliative" corticosteroids was followed by osseou...

Plasmacytoma is a rare plasma cell tumour that arises from plasma cells. The tumour accounts for about 3 - 5% of all plasma cell malignancies and most often affects the head and neck, but may also occur in the gastrointestinal tract. To our knowledge, mesenteric plasmacytoma has not been described previously. We describe the presentation and management of a case of mesenteric plasmacytoma prese...

INTRODUCTION The gross majority of extramedullary plasmacytomas arise in the lymphatic tissue of the upper respiratory tract. On average, one third of patients with a solid plasmacytoma will develop multiple myeloma, resulting in a worse clinical outcome. We describe a case of rapid recurrent extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. CASE PRESENTATION...

Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for estab...

Circulating lymphocytes of plasmacytoma-carrying BALB/c mice were found to lose their normal surface immunoglobulins; in their place surface structures characteristic of the specific plasmacytoma globulin were demonstrated by the immunocytoadhesion technique. These changes were experimentally reproduced by the incubation of normal BALB/c lymphocytes with an RNA preparation obtained by hot pheno...
