Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Cellular Adaptation IV: Dysplasia and Metaplasia

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

Summary

Ameloblastic carcinoma, a rare cancer, can develop anew or from benign tumors. Treatment involves surgery and radiochemotherapy, but prognosis requires caution due to proximity to vital structures.

Area of Science:

Oral pathology
Oncology
Maxillofacial surgery

Background:

Ameloblastic carcinoma is an exceptionally rare malignant odontogenic neoplasm.
It can arise de novo or transformation from a pre-existing ameloblastoma.
Typically affects older individuals.

Observation:

Two rare cases are presented: a primary maxillary ameloblastic carcinoma in a male and a secondary mandibular ameloblastic carcinoma in a female.
The secondary case developed from a pre-existing follicular ameloblastoma.
Both patients underwent adjuvant radiochemotherapy.

Findings:

Ameloblastic carcinoma presents unique challenges due to its rarity and location.
Adjuvant radiochemotherapy showed benefit in both presented cases.
Long-term prognosis remains guarded due to the tumor's proximity to critical anatomical structures.

Implications:

Highlights the importance of vigilant follow-up for ameloblastoma patients.
Emphasizes the role of multimodal treatment including surgery and adjuvant radiochemotherapy.
Underscores the need for careful surgical planning and long-term monitoring in managing ameloblastic carcinoma.
