Desmoplastic infantile ganglioglioma (DIG) is a rare pediatric brain tumor characterized by divergent glioneuronal differentiation and intense desmoplasia ( 1, 2 ).

It is a mixed glial and neuronal cerebral tumor. Desmoplastic infantile ganglioglioma: A MAPK pathway-driven and microglia/macrophage-rich neuroepithelial tumor. Slide Index Categories . Desmoplastic infantile ganglioglioma manifests as an exceptionally large cerebral hemispheric mass composed of both cystic and solid portions (usually more cystic plus a mural nodule) involving both cortex and meninges. All four cases harboring this mutation were non-infantile (10-14 years). The treatment of choice is surgical resection. DIG is a glioma, which is a type of tumor that starts in the glial cells. Despite the large size of these lesions, the prognosis is generally considered favorable after gross-total resection (GTR); however, in incidental cases tumor progression has been described. Diagnosis. In their first report these authors referred to a rare, distinct brain tumor, the main features of which were: 1. Desmoplastic infantile gangliogliomas are rare neoplasms with good prognoses that typically arise in the parietal or frontal lobes, and are most frequently diagnosed before age 2 years.

Ganglioglioma Ganglioglioma is a epilepsy-associated glioneuronal tumour with benign course. 1,29,33,34,39 While both tumors are characterized histologically by prominent desmoplastic stroma, DIA is characterized by a neoplastic population restricted to astrocytes, while DIG includes a population of neoplastic . Desmoplastic infantile gangliogliomas are very rarely encountered, large supratentorial masses, derived from neuroepithelial origin, which have cystic and solid components and contain cells with astrocytic and ganglionic differentiation. Desmoplastic infantile ganglioglioma is a rare superficial supratentorial tumor that occurs within the first two years of life. Neuronal markers (synaptophysin, chromogranin, neurofilament) are positive in the ganglion cells which may be inconspicuous on routine H&E stain. The term desmoplastic infantile ganglioglioma was coined by VandenBerg et al in 1987. Brain. Desmoplastic infantile gangliogliomas (DIGs) are rare intracranial, cystic tumors, usually detected within the first 2 years of life.

Microtubule-associated protein-2 (AP18) and neuron-specific B-tubulin (TUJ-1) were more sensitive in detecting immature neural elements than synaptophysin.

Focused Desmoplastic Infantile Ganglioglioma with stained slides of pathology. Supratentorial superficially located cystic neuroepithelial tumors of infancy characterized by prominent desmoplasia with neoplastic glial component (desmoplastic infantile astrocytoma, DIA) or neoplastic glioneuronal component (desmoplastic infantile ganglioglioma, DIG) Corresponds to WHO grade I Desmopla stic infantile astrocytomas and gangliogliomas are rare, superficial cerebral cortical and leptomeningeal large cystic tumors with dural attachment. Glioneuronal and Neuronal Tumors. Cases with infantile presentation didn't carry this mutation. DESMOPLASTIC infantile astrocytoma (DIA) and desmoplastic infantile ganglioglioma (DIG) are rare, benign CNS tumors that typically present within the first 2 years of life. Desmoplastic infantile tumours (DITs) usually arise in infants in the first 2 years of life [7,15,34,39]; they are large, but history is usually short, suggesting a slow growth rate, until a. None of the cases showed recurrence on follow-up. Dural attachment may make complete resection difficult.

Among those intracranial neoplasms that principally arise in early life are to be found certain neuroepithelial tumors having in common a superficial, Glial cells are the supportive cells in the brain. Clinical studies can benefit participants, the medical field, and the rare disease community in multiple ways. In their first report these authors referred to a rare, distinct brain tumor.

Funding Information: This study . A person may decide to participate in clinical studies because clinical studies often provide: Desmoplastic infantile astrocytoma (DIA) is a rare, supratentorial, dural-based, large cystic tumor that usually arises in the first 24 months of life. It was characterized by its voluminous size, a predominant leptomeningeal growth pattern with intense desmoplasia and divergent differentiation along astrocytic, neuronal and Schwann cell lines. About 60 cases of desmoplastic infantile ganglioglioma have been described in the literature since its first description. The tumours are massive, partially cystic and invariably occur in a supratentorial location. Despite their large size, the overall prognosis is good in most patients. .
