BACKGROUND Metastases of malignant melanoma to the bone marrow are very rare. A few case reports are published in the literature with a known primary site. CASE PRESENTATION Herein we present a case of metastatic malignant melanoma in bone marrow with occult primary site in a 22-year-old-male. Diagnosis was confirmed by morphology and immunohistochemistry. A pertinent review of literature is ...
Although neuroblastoma is a relatively common malignancy of childhood and its dissemination to distant organs is often seen, metastasis to the mandible is rare. A 3-year-old boy which a mandibular soft tissue mass was the initial presenting symptom of disseminated neuroblastoma is reported. The results of biopsy were inconclusive and the differential diagnosis from the imaging studies included ...
IMPORTANCE Disseminated retinoblastoma is usually fatal. Identification of small amounts (minimal dissemination [MD]) of tumor cells in extraocular sites might be a tool for designing appropriate treatments. OBJECTIVE To test cone-rod homeobox (CRX) transcription factor as a lineage-specific molecular marker for metastatic retinoblastoma and for evaluation of MD. DESIGN, SETTING, AND PARTIC...
Approximately 70% of patients with prostatic cancer develop bone metastases. Metastatic prostate adenocarcinomas are associated with high mortality rates and represent a leading cause of cancer-related deaths among males. To study the host-tumor interactions underlying the predilection of prostate cancer cells for skeletal bone, an experimental model was developed using rat Dunning carcinoma Ma...
it is estimated that annually 10 million people are affected by traumatic brain injury and it is one of the major causes of death and disability in accidents. studies have shown the potential therapeutic value of neural stem cell therapies. also, neural stem cell motility and migration to the site of injury has a great regeneration value of the damaged tissues. extracellular and intracellular f...
background: bone marrow-derived mesenchymal stem cells (bmmscs) transplantation has been considered as a promising milestone in liver fibrosis treatment. however, low amounts of homing are a major obstacle. we aimed to investigate the role of melatonin pretreatment in bmmsc homing into experimental liver fibrosis. methods: bmmscs were obtained, grown, propagated and preconditioned with 5 µm mel...
Colorectal cancer (CRC) has a propensity to metastasize to the liver, lungs and regional abdominal lymph nodes, but rarely to the bone marrow. A 60-year-old man presented to the National Hospital Organization Kyushu Cancer Center with a 4-week history of persistent lower back pain, anorexia and difficulty defecating. Complete blood count revealed severe thrombocytopenia and erythroblastosis, su...
Prostate cancer metastasis to bone marrow involves initial adhesion of tumor cells to the bone marrow endothelium, followed by transmigration and proliferation within the marrow. Rapid, specific adhesion of highly metastatic prostate adenocarcinoma cells (PC3M-LN4) to bone marrow endothelial cell (BMEC) lines requires a pericellular hyaluronan (HA) matrix and correlates with dramatically up-reg...
PURPOSE Micrometastatic cells detected in the bone marrow have prognostic significance in breast cancer. These cells are heterogeneous and likely do not exhibit uniform biological behavior. To understand the molecular diversity of disseminated cancer cells that reside in bone marrow, we enriched this cell population and did global gene expression profiling in the context of a prospective clinic...
Lymphatic metastasis of human malignant adenocarcinomas is a critical determinant of prognosis. Lymphangiogenesis, the growth of lymphatic vessels, is closely involved in lymphatic metastasis. However, the mechanisms of tumor lymphangiogenesis are not clearly understood. In a previous study, we showed that human gastric cancer MKN45 cells organize neighboring lymphatic vessels via recruitment o...
