Summary
This report details a rare prognoma, a type of melanotic neuroectodermal tumor, found in a young female child affecting the right maxilla. Prognoma is a dysembryogenic tumor of infancy with few documented cases worldwide.
Area of Science:
- Oncology
- Pediatric Pathology
- Developmental Biology
Background:
- Prognoma is an exceptionally rare dysembryogenic tumor originating in infancy.
- The world literature contains very few documented cases of this condition.
- Melanotic neuroectodermal tumors represent the histopathological classification of prognoma.
Purpose of the Study:
- To present a case report of prognoma in a pediatric patient.
- To highlight the clinical presentation and histopathological findings of prognoma.
- To contribute to the limited existing literature on this rare tumor.
Main Methods:
- Case presentation of a female child diagnosed with prognoma.
- Inclusion of histopathological analysis confirming the tumor type.
- Reporting of relevant biochemical markers associated with the case.
Main Results:
- The tumor affected the right maxilla in the presented case.
- Histopathological examination confirmed prognoma as a melanotic neuroectodermal tumor.
- Elevated serum alpha-fetoprotein and urinary vanillylmandelic acid (VMA) levels were noted.
Conclusions:
- This case adds to the scarce global data on prognoma.
- Prognoma should be considered in the differential diagnosis of infantile tumors, particularly those involving the maxilla.
- Further research is warranted to understand the pathogenesis and optimal management of prognoma.

01:11Oral Cavity
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
