Multiple Solitary Plasmacytoma: A Rare Presentation

Abstract

Central neurocytoma is considered a neoplasm classified as grade II by the WHO, of intraventricular location, although they can be aggressive. Due to the rare incidence, there are no fixed treatment rules or radiation therapy recommendations. Macroscopic total resection is usually curative, however, it is only achieved in 30-50% of cases due to the central location. Adjuvant treatment for optimal neurocytoma management should be considered. Stereotactic radiosurgery is now increasingly recommended as an adjuvant treatment. A case report of a patient treated with postoperative radiosurgery with high local control is presented, and the literature review is also performed.

Multiple solitary plasmocytoma with multifocal medullary asymptomatic presentation for diabetic patient (Case Report)

“…Only a few cases of MSP have been documented in the literature [3,4,5,6]. most of cases reported in the literature of MSP are mainly on vertebral or soft tissue involvement, in our case is very unique for involvement of multiple bone infiltration, mainly of the vault of skull and sternum, costal and humors bilateral , for skull plasmocytoma in the literature they report mainly solitary plasmocytoma ,indeed our case report multiple location of the skull vault and other location , and almost most of the multiple solitary plasmocytoma mimic the metastatic tumor unless confirms the pathological analysis , According to literature search, no case could be found where MSP was associated with skull vault and multiple focal bone infiltration with asymptomatic presentation, although many cases of SBP producing the above features have been reported.…”

“…Skull plasmacytomas are unusual tumors accounting for 4% of all plasma cell tumors [1][2][3][4][5][6]. Most of cases presenting symptoms of headache or symptoms of intracranial hypertension.…”

Endobronchial Mass: A Rare Manifestation of Multiple Solitary Plasmacytoma

“…EMP manifesting as a soft tissue mass in more than one location is very uncommon. The most frequent location of EMP is the upper respiratory tract, including the nasal cavity and sinuses, nasopharynx, and larynx [2][3][4][5][6][7][8][9]. Solitary endobronchial plasmacytoma is the extremely rare manifestation of EMP, described in only a few reports [7].…”

“…MSP is defined as more than one localized area of clonal plasma cells of bone or soft tissue outside the bone (extramedullary) or both in the absence of bone marrow involvement or evidence of systemic disease typical for multiple myeloma [2]. Only a few cases of MSP have been documented in the literature [3][4][5][6]. Primary endobronchial plasmacytoma is an extremely rare condition of extramedullary plasmacytoma [7].…”
