|April 5, 2019
Summary
This case report details an extremely rare instance of intermediate-grade chondrosarcoma in a 31-year-old woman
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Chondrosarcomas are malignant tumors arising from cartilage cells, representing 11% of all bone cancers.
- Primary head and neck chondrosarcomas commonly occur in the nasal cavity, skull base, maxilla, and mandible.
- Chondrosarcomas of the hyoid bone are exceptionally rare, with limited documented cases.
Observation:
- A 31-year-old woman presented with a left submandibular mass.
- Initial fine-needle aspiration cytology suggested a chondroma.
- Computed tomography (CT) imaging identified an exophytic tumor originating from the hyoid bone body.
Findings:
- Histopathological examination of the surgical specimen confirmed an intermediate-grade chondrosarcoma.
- This diagnosis highlights a rare presentation of chondrosarcoma in the hyoid bone.
Implications:
- This case underscores the importance of comprehensive diagnostic evaluation for head and neck masses.
- Accurate histopathological and imaging analysis is crucial for diagnosing rare bone tumors like hyoid chondrosarcoma.
- Further research into the etiology and optimal management of hyoid bone chondrosarcomas is warranted.

01:12The Hyoid Bone
4.9K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

01:16Unusual Results
3.7K
Unusual results are those that have a very low chance of occurring. Unusual results can be identified using probabilities and the range rule of thumb. In problems involving probability, unusual results can be observed in 2 instances – an unusually high number of successes or an unusually low number of successes.
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.
Maximum unusual value =...

01:07z Scores and Unusual Values
11.0K
The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

01:19Graded Potential
6.9K
Graded potentials are localized fluctuations in the cell membrane's electrical charge, commonly found in the dendrites of neurons. The magnitude of these potential changes depends on the strength of the initiating stimulus. In a membrane at its resting potential, a graded potential signifies a voltage shift either above -70 mV or below -70 mV.
Graded potentials fall into two categories: depolarizing and hyperpolarizing. Depolarizing graded potentials typically occur when sodium (Na+) or...

01:35Disassembly of Intermediate Filaments
2.6K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.
Keratin proteins, found at the cell periphery near cell junctions, undergo a cycle of assembly and disassembly. In Type...

01:31Types of Intermediate Filaments
4.8K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
