A 79-year-old man presented with a large tumor on the left side of his head, which had grown over 5 years. Regional lymph nodes were impalpable and computed tomography revealed no signs of bone infiltration. Histology showed that the entire dermis was filled with amorphous eosinophilic material. Immunohistochemistry was negative for cytokeratin, but showed that the dermis and parts of the subcutis were filled with amyloid consisting of immunoglobulin light chains. There were no signs of paraproteinemia or underlying plasmocytoma...

Multiple myeloma (MM) is a neoplasia characterized by the proliferation of plasmacytoid cells, which produce abnormal immunoglobulins. It frequently creates local and systemic complications such as pathologic fractures and renal disease. This article reports the case of a 70-year-old man presenting a pathologic fracture of the right mandibular angle secondary to a plasmocytoma. He had a history of a previous pathologic fracture of the left mandibular angle 13 years before that was treated elsewhere, but no documentation was available...

Presentation of multiple myeloma with bone lesions is common. It is vital that differentiation between nonsecretory multiple myeloma and plasmocytoma be done and that each disorder be treated accordingly. In this paper, we present a patient with nonsecretory multiple myeloma, who suffered from distal humerus fracture with severe bone destruction, renal failure, hypercalcemia and anemia.

Multiple myeloma is a malignant tumour characterized by proliferation of a single clone of plasma cells, this cell line will produce large amount of ineffective immunoglobulins that are ineffective at fighting infection resulting in immunosuppression. These are medullary tumours most of the time; however, in rare cases they may arise extra medullary. The incidence of extramedullary plasmocytoma is about 5% and they arise in the chest most of the time; but they can also arise in other body systems like gastrointestinal system, which is involved in 10% of the time...

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally...

Cancer of unknown primary site is a metastasis developed by the positive feedback loops of primary cancer forming extreme cancer robustness. Such robustness occurs only in metastatic cancer or in relapsed lymphoma, myeloma, plasmocytoma, or leukemia. However, when it develops in primary cancer, hypoxic microenvironment generates positive feedback loops which hyperactivate AKT locus, forming extreme robustness that forcing cancer cells to migrate to the distant site, but primary cancer loosing that property or remains silent...

A cancer positive-feedback loops conversion is the phenomenon and principal mechanism for AKT locus chemotherapy. Such chemotherapy is the approach to target cancer robustness and complexity through the AKT signaling locus. The hypoxic cancer microenvironment generates a powerful signaling interactome with positive-feedback loops that generates cancer robustness through the AKT locus. This complexity and robustness can be successfully halted in leukemia, lymphoma, myeloma, plasmocytoma, sarcoma, and carcinoma by converting cancer positive-feedback loops into negative-feedback loops, achieved through the AKT dephosphorylation by redox balancing change...

BACKGROUND: Multiparameter flow cytometry (MFC) identification and characterization of plasma cells (PCs) is a useful tool to support diagnosis, prognostication, and monitoring of PC diseases (PCD). Currently, the number of MFC markers suited for the identification of PC remains limited. Moreover, antibody therapies against PC-associated markers further compromise the utility of the most widely used reagents (e.g., CD38). Despite markers other than CD38 and CD138 are recognized as potentially useful PC-identification markers, no study has comparatively evaluated their performance in combination with CD38 and CD138...

Brachytherapy has become an established therapeutic regimen for primary, persistent, recurrent and metastatic tumour disease in the head and neck region. This study presents the authors' preliminary experience with intracavitary brachytherapy by means of an individual silicone applicator in the treatment of patients with nasal, sinonasal, orbital and nasopharyngeal cancer. Between January 2001 and January 2013, twenty patients with cancer of the nasal cavity, the paranasal sinuses and nasopharynx underwent surgery and intracavitary brachytherapy with the aid of an individually manufactured silicone applicator in the Department of Otolaryngology, Head and Neck Surgery and in the Department of Radiotherapy and Radiooncology at the Saarland University Medical Center of Homburg, Germany...

PURPOSE: Plasmocytoma of the bone represents a variance of plasma cell neoplasms, which often gives hint for systemic affection. A case of a mandibular tumor as first manifestation of multiple myeloma (MM) is presented and discussed with the literature. MATERIALS AND METHODS: A 76-year old female with pain and swelling of the right lower jaw was assigned to the hospital. Radiograph showed a lytic tumor at the mandibular condyle and histological analysis gave evidence of a plasma cell tumor with positivity to CD138...

Bone marrow-derived mesenchymal stromal cells (BM-MSCs) are under intensive investigation in preclinical models of cytotherapies against cancer, including multiple myeloma (MM). However, the therapeutic use of stromal progenitors holds critical safety concerns due to their potential MM-supporting activity in vivo. Here, we explored whether MSCs from sources other than BM, such as adipose tissue (AD-MSCs) and umbilical cord (UC-MSCs), affect MM cell growth in comparison to either normal (nBM-MSCs) or myelomatous marrow MSCs (MM-BM-MSCs)...

Cutaneous involvement in multiple myeloma (MM) is extremely rare. It may correspond to plasmocytomas, secondary amyloidosis, paraneoplastic syndromes or drug reactions. We report a 75-year-old female with skin lesions, corresponding to extramedullary plasmacytomas (EPs), as a manifestation of MM progression. Most EPs appear in the upper airway and gastrointestinal tract, but have also been described in the genitourinary tract, lung, kidney, thyroid and in 2% of cases, in the skin. Cutaneous lesions are generally associated with terminal stages of the disease and a poor prognosis...

We present a percutaneous modified technique to access large thoracic vertebral body lytic lesions, to increase the volume of tumor accessible to ablation, prior to cement augmentation. Tumor ablation and cavity creation-assisted percutaneous vertebroplasty was considered a palliative measure for structural stabilization in plasmocytoma involvement of the entire T8 vertebral body. Given the extent of osteolysis bilateral combined transpedicular and extrapedicular access to the vertebral body was undertaken to maximize the volume of cavity creation within the tumor...

Cancer robustness is generated by the positive feedback loops. The positive loops hyperactivate AKT locus forming a cancer phenotype in leukemia, lymphoma, myeloma, plasmocytoma, sarcoma and carcinoma. The positive loops inducing AKT hyperphosphorylation increase activity of the AKT locus and the nodal associated and interconnected signaling genes. Only genes expressed above the threshold in the AKT signaling interactome networks, participate in the formation of the complex cancer phenotype. AKT is the switching locus for the cancer phenotype...

BACKGROUND AND AIM: Vertebral involvement is a common occurrence in myelomas, but isolated involvement of the high cervical spine is exceptionally rare. This factor, together with the pediatric age of our patient, makes this case the first report of a plasmocytoma involving C1. CASE REPORT: A 14-year-old boy, without neurological involvement, presented with cervical pain and a palpable posterior neck mass. Cervical spine radiographs showed an osteolytic lesion at C1 compressing the cervical spinal canal and instability of the craniocervical junction...
