Neuroblastoma often spreads to other parts of the body before any symptoms are apparent, and 50 to 60% of all neuroblastoma cases present with metastases. [8] The most common location for neuroblastoma to originate (i.e., the primary tumor) is in the adrenal glands. This occurs in 40% of localized tumors and in 60% of cases of widespread disease.
Pleomorphic anaplastic neuroblastoma (PAN) is a striking aspect of neuroblastoma first described by Cozzutto and Carbone in 1988. Another case was thereafter reported by Cowan, et al. with cytogenetic and immunohistological analysis in a 28-year-old man.
Adrenal neuroblastoma typically presents with a rapidly enlarging abdominal mass. Although the tumor has often spread to distant parts of the body at the time of diagnosis, this cancer is unusual in that many cases are highly curable when the spread is limited to the liver, skin, and/or bone marrow (stage IVS).
Neuroblastomas are PNETS that involve the process of cell differentiation into neurons, [1] [2] while ganglioneuroblastomas are PNETs that involve ganglion cells. [ 1 ] Medulloepithelioma , on the other hand, are tumors involving the constant cell division on the epithelium tissue where bundle of neuron endings are located. [ 1 ]
The most common type of plastic they found was polypropylene, followed by polyamide, nylon and polyethylene vinyl acetate. “Propylene is everywhere, in furniture, rugs, clothes,” Mauad said.
The degree of differentiation of neuroblastoma is correlated to the prognosis, with a wide variety of outcomes (from tumor regression to recurrence and mortality). The standard of care is the use of chemotherapy, surgical resection and radiation, although most aggressive neuroblastomas have demonstrated to be resistant to these therapies. [8]
