Squamous Carcinoma after Dental Implants: A Clinical Case

Evaluation of the Effects of Dental Implants on Oral Lesions

“…5 In a study by Chimenos-Kustner et al of a 62-year-old woman with a history of moderate consumption of alcohol (consumption for 2 years prior to surgery), and tobacco (cessation of smoking 10 years previously), it was reported that squamous cell carcinoma (SCC) was detected around the implant as a rapid growth exophytic lesion a few weeks after the implant placing. 35 In some cases, the inflammation around the implant may persist over a long period without malignant trans-formation. Gulati et al reported a case of a 62-year-old woman with a long history of smoking (20 cigarettes per day) with a white patch in the mouth that was diagnosed as SCC histopathologically.…”

Cancerous lesions in the vicinity of dental implants: a systematic review

“…In fact, in 5 of the aforementioned cases there was a combination of previous carcinomas and potentially malignant mucosal disorders [20,27,28,32,36,38]. In 9 cases, the authors did not describe this aspect [23,25,35,36,41,46], and only 15 patients without a history of lesions of this type [6,15,19,21,22,24,[30][31][32][33][34]47].…”

“…In addition, in 18 cases, no risk factors were identified [6,20,22,26,30,[32][33][34]36] and in 27 cases the authors did not mention whether there were any risk factors [5,6,14,16,17,24,25,27,35,36,38,[42][43][44][45][46]. Among the remaining 33 cases, the following risk factors were identified: smoking [6,21,25,26,36,37,39] (or being an ex-smoker [18,23,28,30,32,47]), alcohol consumption [6,9,21,23,[29][30][31]39,47] (or being an ex-alcohol drinker [32]), or both [6,…”

“…One author described a clinically acceptable peri-implant appearance in one patient, while radiographically, there was radiolucency along the length of the implants [44]. Some authors describe associated cervical lymphadenopathies [19,29,32,[35][36][37]41], verrucous carcinomas [32,45], paraesthesia [36,40,43] (including numb chin syndrome [44]), pain [43], lesions that did not respond to conventional treatment [5,9,[20][21][22]35,36] and of rapid evolution [13,18,23,28,32,37,42,45], bone expansion, trismus [36], purulent drainage [43] and mobility of teeth adjacent to the implant [40] or of the implants themselves [13,32]. In one case, the presence of metal filings from the implant in the affected peri-implant mucosa was described [29] and in another, the sudden appearance of cellulitis of the mental nerve area without associated bone lesions that led to the loss of osseointegration of the implant [32].…”

Oral Cancer around Dental Implants Appearing in Patients with\without a History of Oral or Systemic Malignancy: a Systematic Review

“…The lesion was found 5 years after implant placement. In 2008, Chimenos-Küstner et al [ 23 ] reported a case of a 62-year-old woman, moderate ex-smoker, who quit smoking tobacco 10 years ago and she was a moderate alcohol consumer, without a prior history of cancer. A few weeks after the implants were inserted in positions #41 and #31, she began to develop a fast-growing exophytic lesion around them.…”
