Carcinoma cuniculatum, a very well differentiated sub-type of epidermoid carcinoma, is a rare invasive tumor with a low risk of metastasis. It principally affects the lower limbs, notably the soles of the feet. Facial involvement is exceptional. A case of a patient with carcinoma cuniculatum of the lower lip is presented and diagnostic difficulties of head locations of this tumor, as well as their management are discussed., (Copyright © 2018 Elsevier Masson SAS.

Background and Objective: The aim of this study was to evaluate the effectiveness of a modified radical neck dissection with preservation of non-lymphatic structures usually removed in advanced-stage head and neck epidermoid carcinoma associated with postoperative radiotherapy (PORT)., Methods: We analyzed retrospectively the files of 109 patients, presenting with epidermoid carcinoma of the upper digestive/respiratory tract staged N2 or N3, over a 6-year period. The rates of regional control, mortality, and recurrence were analyzed and linked to the kind of neck-dissection (usual radical neck dissection [RND], modified radical neck dissection [MRND], selective neck-dissection [SND]) performed., Results: Forty-three neck dissections were RND, 92 were MRND, and 21 were SND. PORT was used in all cases. The mean follow-up was 57.3 months. The overall rate of regional control was 93.6% (97.7% for RND and 93.5% for MRND; p=0.35). Patients having undergone MRND had a better prognosis and less recurrence then patients having undergone RND (respectively p=0.007, and p=0.0004)., Discussion: MRND in association with PORT is an effective treatment in patients with advanced head and neck epidermoid carcinoma staged N2 and N3.

Introduction: Etanercept (Enbrel) is a TNF-alpha inhibitor effective in rheumatoid polyarthritis, psoriatic rheumatism, ankylosing spondyloarthritis, chronic plaque psoriasis, and juvenile idiopathic arthritis. Several cases of tumours have been described in patients under etanercept. However, no case of association with oral carcinoma had ever been described. The aim of this study was to report a case of carcinoma of the cheek mucosa in a patient treated with etanercept for rheumatoid polyarthritis., Observation: An 82-year-old female patient, non smoker, consulted for a tumour of the oral cavity. History revealed that this lesion had appeared soon after the initiation of etanercept treatment for severe and resistant rheumatoid polyarthritis. Clinical observation revealed a tumour of the right cheek mucosa 5 by 3 cm. The lesion was superficially infiltrative, budding in spots, and verrucous. The clinical observation was otherwise normal. The histological examination of the surgical piece revealed a micro-infiltrative and non-invasive orthoplastic epidermoid carcinoma., Discussion: The possible development of an oral cavity carcinoma should be taken into account when following a patient under TNF-alpha inhibitor treatment. Anti-TNF treatment has improved the management of patients with severe chronic inflammatory diseases. They allow for a better quality of life. Nevertheless, their immunosuppressive effect should be taken into account when prescribed and during follow-up.

Objective: The aim of this preliminary retrospective study was to evaluate the prognostic value of tumor thickness in squamous cell carcinoma of the floor of the mouth., Materials and Methods: A total of 61 patients with previously untreated T1N0, T2N0 or T3N0 squamous cell carcinoma of the floor of the mouth were included in this preliminary study. An optical micrometer was used to determine the maximum of tumor thickness. We studied the relation between the overall survival at two and five years and tumor thickness., Results: The cohort comprised 52 male and nine female patients. The mean and the median thickness were 7.2 and 6mm, respectively. Overall survival was 79.5 and 36.7% at two and five years, respectively. There was no significant association between thickness and overall survival (p=0.71) and between thickness and disease-free survival (p=0.63)., Conclusion: The prognostic value of tumor thickness was not demonstrated in this preliminary study. We are currently conducting a study involving a larger patient population in our unit and we believe that tumor thickness should be considered in the management plan for patients with oral carcinoma.

Introduction: Most cancers of the oral cavity are epidermoid carcinomas. The prognosis is made on the patient's general health status and the tumoral stage. The UICC TNM staging classification system is one of the most important factors taken in consideration for the prognosis. But this classification in oral epidermoid carcinomas does not include the tumor thickness (except for T4 tumors). Several studies demonstrated that tumor thickness could influence the prognosis in epidermoid carcinoma and other types of cancers. The aim of our retrospective study was to assess the prognostic value of tumor thickness in oral epidermoid carcinoma., Patients and Methods: The study included patients with mouth floor or mobile tongue epidermoid carcinoma classified T1N0, T2N0 and T3N0 between 1985 and 2005. All patients were treated with a curative intention. A pathologist analysed the tumor thickness and cervical lymph nodes. All the slides were examined to measure tumor thickness in millimetres., Results: Three hundred and five patient files were reviewed and 124 patients were included, with 94 men (75.8%), and a mean age of 59.3 years (17-93). The mean and median tumor thickness were respectively 7.7 and 6.5 mm (0.4-30). The median tumor thickness was chosen for the study. There was a statistically significant link between the five-year probability of global survival and the initial tumor thickness and between neck node invasion and tumor thickness (p<0.05)., Discussion: This study suggests that tumor thickness should be taken in consideration in T1N0, T2N0 and T3N0 mouth floor and mobile tongue epidermoid carcinomas. In the future, the clinical evaluation of tumor thickness will help determine the therapeutic management.

Introduction: Squamous cell carcinoma of the oral cavity is often a single localization, but the discovery of another or several associated lesions is not exceptional. The goal of our study was a retrospective analysis of patients having 2 simultaneous squamous cell carcinomas of the upper aerodigestive tract (UADT), i.e. diagnosed during the same panendoscopy by excluding the esophagus and the lung., Patients and Methods: Between 1995 and 2001, 1,129 patients were treated for squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, and larynx in the Bordeaux Maxillo-facial Surgery Unit. 1% of these patients presented 2 simultaneous squamous cell carcinomas of UADT., Results: Our series was divided in 9 men (75%) and 3 women (25%) with an average age of 61.3 years (48-86). At the end of the study 2 patients were lost to follow-up, 3 patients were alive without recurrence, and 1 patient was alive with recurrence. The average follow-up time was 17.6 months., Discussion: A review of the literature gave an incidence of simultaneous squamous cell carcinomas of UADT varying from 1.3 to 12.8% according to authors. Thus, any patient having squamous cell carcinoma of the UADT must be considered as having an important potential risk to present another simultaneous cancer and to benefit from a systematic panendoscopy. In spite of an early diagnosis, the prognostic of these lesions remains bad.

Purpose: The aim of this retrospective study was to determine a rational of treatment of squamous-cell carcinoma of the upper gum and hard palate., Patients and Method: We analyzed retrospectively a series of 34 patients treated over a period of 11 years., Results: There were 19 women (76%); mean age was 67.3 years; 76% had advanced tumors; 28% had neck nodes. The 5-year survival rate was 33.7%; patients without node involvement had better prognosis (p=0.034). The 5-year rate of recurrence-free survival was 61%; patients without node involvement had better prognosis (p = 0.032). At the end of the study, only 42% of patients were still alive., Discussion: This type of tumor is different from those of other locations in the oral cavity or oropharynx. At the present time, surgery associated or not with post-operative radiotherapy seems to be optimal curative treatment. The question of whether neck dissection should be performed remains debated for patients without clinically nodes.

Objective: To analyze a review of literature of patients aged less than 20 years with epidermoid carcinoma of oral cavity., Patients and Methods: Two sources were used to identify cases. A Medline search was performed as well as a review of our Medlog files where two cases of oral epidermoid carcinoma were identified in patients aged less than 20 years., Results: Sixteen patients treated between 1981 and 2000 were included in this study. The mean age was 15.6 years and the sex ratio was 2.2 male/female. The mean time to diagnosis was 16.4 months. Tumors were staged III or IV in 71.4% of cases. The mean follow-up was 33.2 months. Rate of failure was 50% and one patient experienced local recurrence. At last follow-up, seven patients were alive with one patient living with cancer. All deaths resulted from the original cancer., Discussion: This study illustrates the rarity of epidermoid carcinoma of the oral cavity in patients aged less than 20 years. Owing to the fact that most tumors were classified III or IV, time to diagnosis is probably the most important prognosis factor. Histological examination of all lesions of the oral cavity is required, irrespective of the age of the patient.

Objective: The aim of the study was to assess the results of curative treatment of patients with squamous cell carcinoma of the tongue and to evaluate survival and predictive factors of recurrence., Patients and Methods: A series of 309 patients with squamous cell carcinoma of the tongue treated with curative intent was studied from January 1988 to December 1999. The percentage of oral tongue cancer was 82.2 and the percentage of cancer of base of the tongue was 17.8. Most patients underwent surgical procedure alone or combined with radiotherapy (92%). We performed 252 neck dissections. Bilateral dissections were performed for cancer of the apex linguae, cancer of the base of the tongue, for patients with N2c neck disease and whenever the primary tumor site crossed the median line. Twenty-five patients (8%) were treated with radiation therapy alone. Mean follow-up was 55 months. The functional results were assessed within a minimum of 10 months postoperative follow-up., Results: In 45.2%, there was histological evidence of node invasion with 53.5% of extracapsular node spread in the neck specimens. Extracapsular node spread did not influence survival or recurrences. Occult cervical metastasis in an elective neck dissection in clinically negative necks was found in about 20% of patients with 47% of extracapsular node spread (41% for cancer of mobile tongue and 80% for those of base of the tongue). About 23% of patients with cancer of base of the tongue staged N0 had histological node invasion in controlateral neck nodes. The postoperative mortality rate was 0.9%. The rate of complications was 17%. The cancer recurred in 41.7% of all cases. Twelve percent of all patients had second primary cancers of the upper aerodigestive tract. The overall survival and non-recurrence rates at 2 and 5 years were higher in cancer of oral tongue than in cancer of base of the tongue. Survival rates were better when neck nodes were clinically or histologically negatives and in early-stage carcinomas. Non-recurrence rates were better when nodes were clinically or histologically negatives and when margins of exeresis were not involved. The functional results were better in oral tongue cancer than in base of the tongue cancer., Discussion: Prognosis (survival and non-recurrence rates and functional results) of squamous cell carcinomas of oral tongue was better than prognosis of those of base of tongue. We recommend an aggressive surgical procedure even in patients with neck classed N0 (with reservations for T1 lesions with small depth of invasion): an ipsilateral supraomohyoid neck dissection for cancer of oral tongue and a bilateral supraomohyoid neck dissection for cancer of base of the tongue, cancer of oral tongue which crosses the median line of the oral cavity and cancer of the apex linguae. Postoperative radiotherapy must be performed when margins are positives and/or when nodes are involved with or without extracapsular spread.

Lips repair cannot be considered until the characteristics of the loss of substance which are given by its aetiology, has been carefully determined. Traumatic aetiologies remain dominated by accidents on the public roads associated more often with adjacent damage. Dog bites remain the burden of children and always raise the problem of their septicity. For burns there is a need to wait for the organism to delimit its own viable tissues. Ballistic traumatisms will lead to major damage where functional repair to the lips can often be very difficult. Tumours of the lips, essentially malignant, lead to wide exeresis, where the margins are dictated by histological findings. They, of course, pose the problem of eventual neck node dissection and are dominated by squamous cell carcinomas.
