The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited...

Inflammatory myofibroblastic tumor (IMT) is a rare tumor in the central nervous system (CNS), mostly being extracranial. Approximately 100 sporadic cases have been reported in the literature. The rarity of the tumor, its various histopathological characteristics, and its variable aggressive course render it difficult to diagnose and treat. IMT is generally a histological diagnosis which is rarely suspected preoperatively. It mimics other intracranial tumors such as giant cell tumor, hemangiopericytoma, anaplastic meningioma, plasmacytoma, and lymphoma...

We reported a rare solitary osteogenic sternum plasmacytoma case. A 49-year-old woman experienced progressing pain in the sternum for 2 years. Abnormal Tc-MDP accumulation and increase in F-FDG uptake (SUVmax, 4.4) were co-localized with the osteogenic lesion in the sternum body detected by diagnostic CT. The lesion was histologically confirmed as plasma cell neoplasm suggestive of plasmacytoma. The patient had good response to radiotherapy.

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 extramedullary plasmacytoma. Also, the prognosis is different: even if both forms respond well to treatment, overall survival and progression-free survival of solitary bone plasmacytoma are poorer than solitary extramedullary plasmacytoma due to its higher rate of evolution in multiple myeloma...

We present a rare case of a patient with delayed gastric emptying, gastric phytobezoar formation, and osteosclerotic bone lesions as an atypical association with multiple myeloma. Associated gastric features in myeloma, which include diffuse infiltration, gastric plasmacytomas, or delayed gastric emptying, are rare and have a poor prognosis.

Extramedullary plasmacytomas, Epstein-Bar virus (EBV) associated, are rarely encountered and usually have a fairly good clinical outcome. EBV+ plasmacytoma may cause a diagnostic dilemma as it phenotypically resembles an aggressive plasmablastic lymphoma (PBL). Herein, we report a unique case with maxillary EBV+ plasmacytoma from a 76-year-old immunocompetent individual.

BACKGROUND: Over the past three decades much has changed in the treatment and outcomes of patients suffering concurrently from both multiple myeloma (MM) and HIV. While the prevalence of MM appears to be higher in HIV-positive individuals than in those who are uninfected, early recognition of patients suffering from both diseases is difficult and little information is available on their demographics and clinical presentation. OBJECTIVE: To compare the presenting features of HIV-positive patients diagnosed with MM with those of HIV-negative patients...

BACKGROUND: Plasma cell neoplasmas are a heterogenous group of neoplastic tumor lesions occurring secondary to disordered proliferation of cells from a monocyte lineage. Plasmacytoma is a rare lesion that accounts for 5% of all plasma cell neoplasms. The current recommended treatment for solitary plasmacytoma is moderate dose radiation therapy. For patients who are suffering from axial back pain, spinal instability, radiculopathy, or bowel/bladder dysfunction secondary to spinal cord compression, surgical intervention with spinal decompression and stabilization can be used as an adjuvant to radiation therapy...

Although rare, both central nervous system and pericardial involvement of myeloma have been well described in the literature. Their simultaneous occurrence in relapsed disease, however, has not been previously reported. This case describes a 54-year-old female who was treated for high-risk multiple myeloma with multiregimen chemotherapy and allogeneic hematopoietic stem cell transplantation. Four months after transplant, she was found to have relapsed disease manifesting as an extraosseous, intracranial plasmacytoma and simultaneous malignant pericardial effusion...

This retrospective study aimed to compare the clinical features of paramedullary lesions (PLs) and extramedullary lesions (ELs) of plasmacytomas at diagnosis, using positron emission tomography integrated with computed tomography, using glucose labeled with the positron-emitting radionuclide (18)F ((18)F-FDG-PET/CT) in newly diagnosed multiple myeloma (NDMM), and to address their prognostic impact. Sixty-four patients with NDMM presenting ELs (n=22) and/or PLs (n=42) were included. Patients with ELs at initial presentation had unfavorable laboratory parameters of calcium and lactate dehydrogenase, a higher percentage of bone marrow plasma cells, and showed a trend toward advanced international staging system (ISS), compared to patients with PLs...

Multiple myelomas (MM) of the immunoglobulin D (IgD) subtype is rare amongst plasma cell malignancies. It can present a diagnostic challenge because of the low amount of immunoglobulin in the serum. The amount of monoclonal (M)-protein is often undetectable on electrophoresis. Historically, survival in these patients was typically shorter compared to the immunoglobulin A (IgA) and immunoglobulin G (IgG) subtypes due to advanced disease upon presentation. With the advent of better diagnostic techniques, the prognosis of this disease is changing...

The association between plasmacytomas and multiple myeloma (MM) is well-described, and in about one third of the cases of plasmacytoma the additional study will lead to the diagnosis of MM. The finding of plasmacytomas in the genital tract is extremely rare, with sparse cases described in the literature, and these cases pose a challenge regarding the optimal guidance and treatment. This paper describes a case of uterine extramedullary plasmacytoma in a 79-year-old woman with complaints of postmenopausal abnormal uterine bleeding...

We describe a case of an extramedullary plasmacytoma (EMP) in an HIV-positive child. An 11- year-old, HIV-infected female patient, on antiretroviral therapy since 2010, was referred with difficult to control asthma and bronchiectasis. The lesion was identified on CT chest following persisting reduced air entry and unilateral wheezing on the right. Rigid bronchoscopy identified a large pedunculated fleshy mass in the right main bronchus. Biopsy revealed it to be a plasmacytoma. Right main bronchus sleeve resection was done with complete removal of the tumor...

INTRODUCTION: Multiple myeloma (MM) is considered as a disease of the old with the reported median age of 60-70 years. The disease occurred a decade earlier in the Indian subcontinent. The literature on MM in adolescents and young adult (AYA) is limited. We studied the disease characteristics and outcomes of the AYA-MM in the real-world setting. PATIENTS AND METHODS: It is a retrospective single-center study conducted at a tertiary care center from North India. Records of all consecutive patients with AYA-MM (15-39 years of age) who were managed from January 1, 2010, to December 30, 2015, were reviewed...

PURPOSE: Solitary plasmacytoma (SP) is a rare plasma-cell neoplasm, which can develop both in skeletal and/or soft tissue and frequently progresses to multiple myeloma (MM). Our aim was to study the metabolic behavior of SP and the role of 18F-FDG-PET/CT in predicting progression to MM. MATERIALS AND METHODS: Sixty-two patients with SP who underwent 18F-FDG-PET/CT before any treatment were included. PET images were qualitatively and semiquantitatively analyzed by measuring the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and compared with age, sex, site of primary disease, and tumor size...
