Summary
Squamous cell carcinoma around dental implants is rare and mimics peri-implantitis. Early diagnosis through biopsy is crucial for patients with risk factors like smoking.
Area of Science:
- Oral oncology
- Dental implantology
- Oncologic surgery
Background:
- Squamous cell carcinoma (SCC) developing around dental implants is infrequently documented.
- This condition often presents with symptoms that mimic peri-implantitis, leading to diagnostic challenges.
Observation:
- Two cases are presented: a 70-year-old woman with an mandibular tumor around implants and a 72-year-old male smoker with chronic lichen planus and a tumor around implants.
- Radiographic examination revealed significant osteolysis around the implants in both patients. One implant was spontaneously expelled.
Findings:
- Histopathological examination confirmed squamous cell carcinoma in both cases.
- The direct carcinogenic role of the dental implant itself remains unestablished.
- An alternative hypothesis suggests malignant cell migration from mucosal tumors through the gingival sulcus.
Implications:
- Patients with risk factors for SCC (e.g., smoking, alcohol use, precancerous lesions) require vigilant, long-term follow-up after dental implant placement.
- Biopsy is essential for definitive diagnosis of suspected peri-implant malignancies.
- Distinguishing SCC from peri-implantitis is critical for appropriate patient management and prognosis.

01:30Bacterial Signaling
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
01:30Skin 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.

01:24Cellular 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...
