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.
Appearance of focal or diffuse presence of pleomorphic and anaplastic cells is the hallmark of this neuroblastoma variant. [1] [4] [5] Hyperchromatic and bizarre nuclei in neuroblasts and ganglion cells in undifferentiated or poorly differentiated foci are far too pathognomonic, although anaplastic expressions can be found in differentiating foci alike.
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
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]
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. Researchers from the University of New Mexico Health ...
In neuroanatomy, topographic map is the ordered projection of a sensory surface (like the retina or the skin) or an effector system (like the musculature) to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems.
