ABSTRACT

BACKGROUND: Oral squamous cell carcinoma (OSCC) of the gingiva represents less than 6% of intraoral carcinomas. CASE REPORT: A 51-year-old male patient presented with a history of a symptomatic red spot with periods of remission and recurrence in the mandibular gingiva. On clinical examination red and white areas were observed in the gingiva, particularly around the left lower molars. Diagnosis of gingival lichen planus was suspected and topical corticosteroids was prescribed. A good clinical response was observed with reduction of symptom. The patient remained in regular follow-up and after 9 months, the lesion suddenly changed, became ulcerated and diagnosis of OSCC was established. CONCLUSION: The clinical manifestation of OSCC can eventually mimic other even more common lesions of the oral mucosa, highlighting the importance of considering OSCC as differential diagnosis of any unexplained and persistent lesion in the oral cavity.

ABSTRACT

Despite the long-term survival rates of osseointegrated dental implants, several biological complications are known to affect the peri-implant tissues, such as peri-implant mucositis and peri-implantitis. Occasionally, the clinical features of these more common benign lesions, or others nonrelated to implants, might be similar to oral malignancies, leading to misdiagnosis. The objective of this study was to present a case series of oral cancer located adjacent to dental implants, aimed to identify the reasons for initial misinterpretation of diagnosis. Thirteen patients, 10 females and 3 males, aged 59 to 90, were assessed. Among the differential diagnoses established, a malignant or premalignant lesion was not considered in 10 out of the 13 patients. Peri-implantitis was the most common preliminary diagnosis, followed by fungal infection, viral infections, and traumatic ulcers. The meantime for the diagnosis of oral cancer was 21.5 months. The clinical presentation of peri-implant malignancy, such as ulceration, white and red plaques, and exophytic lesions, might mimic benign diseases that are more common in the oral cavity. Suspicious lesions with treatment failure that persist for more than 2 weeks require biopsy and histopathological analysis to establish an early definitive diagnosis to improve the prognosis and quality of life of the patients.

ABSTRACT

Oral leukoplakia (OL) is a white lesion with high potential of recurrence and malignant transformation. The variable clinical and histopathological features of OL may potentially impact both treatment and prognosis. Current literature shows that post treatment rates of recurrence and malignant transformation vary widely. The use of surgical lasers have been proposed with the objective of improving outcomes. We performed a systematic review and a comprehensive meta-analysis dedicated to pooling the rates of recurrence and malignant transformation of OL lesions treated using the main types of surgical lasers available. Scopus, MEDLINE/PubMed, and Embase were searched electronically. A total of 36 articles met the inclusion criteria. Selected studies included OL lesions that were treated by evaporation or excision using Nd:YAG laser, Er:YAG laser, CO2 laser, KTP laser, or diode laser. The results of this systematic review and meta-analysis suggest that surgical laser excision of OL may decrease recurrence rates but have no effect on the malignant transformation of OL when compared with conventional treatments.
