Extramedullary plasmacytoma of the liver is a very rare tumor. Although a few cases of extramedullary plasmacytoma of the liver have been reported, we could not find any report on truly localized extramedullary plasmacytoma of the liver in the literature. The patient was a 63-yr-old man who exhibited a solitary liver mass on dynamic computed tomography and magnetic resonance imaging. Histologic...

Plasmacytomas are a localized proliferation of plasma cells in the bone marrow, and are less frequently seen in extraosseous organs or tissues. Extramedullary plasmacytoma is a rare malignant neoplasm, and is especially uncommon when it arises from the mediastinum. Here, we report on a case of posterior mediastinal extramedullary plasmacytoma in a 64-year-old man. He was admitted with an asympt...

solitary plasmacytoma in the right shoulder in 2002, which was treated with local radiotherapy. In December 2004, new plasmacytomas in the knee and ankle were diagnosed and treated with radiotherapy and chemotherapy, with good clinical response. In November 2007, a new plasmacytoma in the right thigh was diagnosed and systemic treatment was chosen. The patient developed cholestatic jaundice aft...

Malignant plasma cell proliferation can be presented as part of disseminated disease of multiple myeloma, as solitary plasmacytoma of bone, or in soft tissue as extramedullary plasmacytoma. Extramedullary plasmacytomas represented approximately 3% of all plasma cell proliferation. Approximately 80% of extramedullary plasmacytomas occur in the head and neck region while the other 4% occur in the...

Solitary bone plasmacytoma belongs to a group of lymphoproliferative clinical disorders typified by clonal proliferation of plasma cells. Solitary plasmacytoma typically involves a single bone or extramedullary site. It commonly occurs in the vertebrae or thorax, and rarely involves the mandible. The aim of this report is to present a rare case of solitary plasmacytoma of the jaws mimicking per...

BACKGROUND Extramedullary plasmacytomas are seldom solitary and usually progress to diffuse myelomatosis. Plasmacytomas of the breast are rare, especially when not associated multiple myeloma. Synchronous infiltrating ductal carcinoma and primary extramedullary plasmacytoma of the breast have not previously reported. CASE PRESENTATION A 27-years-old woman with an untreated upper outer quadran...

Primary plasmacytoma of the thyroid is a very rare tumour. We report a case and emphasize the importance of excluding multiple myeloma which may present as an extramedullary plasmacytoma. Histological diagnosis has been simplified by the use of immunohistochemical techniques.

Solitary plasmacytoma is a rare disease characterized by a localized proliferation of neoplastic monoclonal plasma cells, without evidence of systemic disease. It can be subdivided into solitary bone plasmacytoma if the lesion originates in bone, or solitary extramedullary plasmacytoma if the lesion involves a soft tissue. The incidence of solitary bone plasmacytoma is higher than solitary extr...

Extramedullary plasmacytomas and/or endobronchial plasmacytomas are rare conditions. We present this case due to its rarity. The patient who was diagnosed with extramedullary plasmacytoma of the right vocal cord ten years ago and nasopharynx two years ago was referred to our unit with hemoptysis. A suspicious lesion was detected in the right intermediate bronchus in the thoracic computed tomogr...
