Oral Pathology Malignant Tumors Quiz

Uncontrolled growth of tissue that is locally invasive, has high cellular anaplasia, and can spread to lymph nodes or distant organs.

A malignant tumor starting in the body's original location, such as the oral cavity.

A malignant tumor that started in another part of the body and spread to a new location, like the jaw.

Cancer caused by exposure to things like viruses, radiation, genetic defects, or harmful chemicals.

Pain or rapid swelling without any clear dental cause.

Soft tissue lesion with an indistinct border, lacking a defined capsule and often showing a radiolucent periphery.

Areas in the jaw that are more commonly affected by different types of malignant tumors.

Originating from epithelial tissues, commonly seen in the tongue, floor of mouth, etc.

Large lesions can obstruct the airway, eustachian tube, or nasopharynx. Patients may experience significant weight loss and feel unwell.

Commonly found on the lateral border of the tongue, floor of the mouth, and gingiva. Can also affect tonsils, soft palate, and buccal vestibule.

Polymorphous, irregular shape due to bone erosion. Invasion often observed with an ill-defined, non-corticated border.

Completely radiolucent, meaning the original bone structure is lost.

WIDENING of the periodontal ligament space and DESTRUCTION of adjacent lamina dura. Teeth may appear floating without bony support.

Tumors can grow along the inferior neurovascular canal and through the mental foramen, widening and eroding the surrounding bone.

Destruction of normal cortical boundaries like the maxillary sinus, buccal, and lingual plates. Thinning or destruction of the mandibular border.

Osteomyelitis produces periosteal reaction (new bone formation), whereas squamous cell carcinoma does not.

A type of cancer that starts in the squamous cells, which are flat cells that make up the lining of the mouth, skin, and other parts of the body. It can occur in different locations in the mouth.

SCC that originates within bone, often arising from the lining of a cyst or other pre-existing structures.

SCC that begins within a cyst, often related to dental problems.

SCC that starts in the maxillary sinus, a hollow space in the upper jaw.

A type of tumor that originates from epithelial cells within bone, potentially arising from the lining of a cyst.

The most common symptom of Central Mucoepidermoid Carcinoma is a painless swelling in the affected area. It may be a slow-growing tumor that feels like a lump.

Aggressive, fast-growing lesions often have irregular borders and an opaque appearance on radiographs.

Smooth-bordered and radiolucent lesions, meaning they appear dark on X-rays, can resemble normal structures like cysts or granulomas, making diagnosis challenging.

A type of malignant tumor that starts in the cells that form enamel in the teeth.

The most common primary tumors that metastasize to the jaws, often originating from the breast, lungs, and prostate.

A hard, expanding growth in the jaw with displaced teeth and normal overlying mucosa. May cause a slight tenderness.

Well-defined borders with cortical boundaries. However, it can breach the cortex, invading the soft tissue.

The tumor often presents with a honeycomb or soap bubble pattern on radiographs, with thick septa.

Usually found in the mandible, more prevalent in the premolar and molar region.

Occurs in older adults, especially women, with a ratio of almost 2:1.

A type of malignant tumor that starts in another part of the body and spreads to the jaw.

The maxillary sinus, anterior hard palate, and mandibular condyle are common locations for metastatic tumors.

Metastatic tumors in the jaw can resemble inflammatory lesions or periapical disease.

The tumor margins may lack a distinct border and have irregular shapes.

The malignant tumor disrupts the normal bony structure around the teeth's roots.

Tumors, like those from prostate or breast cancers, can cause the bone to become denser.

A spiculated pattern on X-rays can indicate tumors like those from prostate or neuroblastoma.

The tumor can cause a widening of the space between the tooth root and the bone, unlike inflammation.

A type of tumor that often arises in the mandible, typically above the mandibular canal in the premolar/molar area. It is known for its well-defined, often corticated borders and a multilocular radiolucent appearance resembling a soap bubble or honeycomb structure.

This tumor tends to expand and may perforate the surrounding bone, sometimes even extending into the soft tissues. While it often pushes the mandibular canal, the teeth themselves are usually not directly affected.

This tumor can be mistaken for benign odontogenic tumors due to its appearance, but its aggressive nature is revealed by its tendency to expand and potentially perforate the bone, even extending into surrounding tissues.

These tumors are categorized by their behavior rather than just their appearance. Malignant ameloblastoma is recognized for its tendency to metastasize despite benign histological features. Ameloblastic carcinoma, on the other hand, exhibits classic malignant characteristics at the cellular level, like abnormal cell division and enlarged nuclei.

This tumor, marked by its aggressive nature, expands outward and may even break through the outer bone to infiltrate surrounding tissues.

Cells in this tumor display characteristics of malignancy with abnormal cell division and enlarged nuclei. This differentiates it from malignant ameloblastoma, which may not show these features at the cellular level.

The distinctive feature of this tumor is the prominent cortication, which is a thick layer of bone surrounding the lesion.

This type of tumor is often found in the jaw, more commonly in the mandible compared to the upper jaw.
