  • Oral and Maxillo-Facial Manifestations of Systemic Diseases: an Overview
    medicina Review Oral and Maxillo-Facial Manifestations of Systemic Diseases: An Overview Saverio Capodiferro *,† , Luisa Limongelli *,† and Gianfranco Favia Department of Interdisciplinary Medicine, University of Bari Aldo Moro, Piazza G. Cesare, 11, 70124 Bari, Italy; [email protected] * Correspondence: [email protected] (S.C.); [email protected] (L.L.) † These authors contributed equally to the paper. Abstract: Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors present an overview on the most frequent clinical manifestations at the oral and maxillo-facial district of systemic disease. Keywords: oral cavity; head and neck; systemic disease; oral signs of systemic diseases; early diagnosis; differential diagnosis Citation: Capodiferro, S.; Limongelli, 1. Introduction L.; Favia, G.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Oral signs are frequently the first manifestation of autoimmune diseases. For this reason, dentists play an important role in the detection of emerging autoimmune pathologies. Indeed, an early diagnosis can play a decisive role in improving the quality of treatment strategies as well as quality of life. This can be obtained thanks to specific knowledge of oral manifestations of autoimmune diseases. This review is aimed at describing oral presentations, diagnosis, and treatment strategies for systemic lupus erythematosus, Sjögren syndrome, pemphigus vulgaris, mucous membrane pemphigoid, and Behcet disease. 1.

The relationship between perianal fistula in CD (Chron’s disease) and SCC (squa- mous cell carcinoma) development is not clear but chronic inflammation of ano-rectal mucosa, delayed wound healing and cell turnover may play important roles. The aim of this systematic review was to determine the clinical characteristics of patients with squamous cell carcinoma arising from perianal fistula in CD, the surgery and oncological treatment, the role of HPV infection, im- munosuppression and the survival of these patients. Fistula-related carcinoma in CD can be very difficult to diagnose. An early diagnosis has the potential to improve the outcome of disease.

  • Diagnostic Discussion
    Diagnostic Discussion Diagnostic Discussion By Drs. Indraneel Bhattacharyya and Nadim Islam A 44-year-old female was referred to Dr. Daniel Lauer, a periodontist in Palm Beach Gardens, Fla., for evaluation of a mildly symptomatic lesion on the palate (Fig. 1) by her dentist, Dr. Jimmy Chen, also of Palm Beach Gardens. The patient reported a his- tory of food-related trauma to her palate four to six weeks before the lesion appeared. She complained of mild irritation in the area, especially on food con- sumption. Her medical history was non-contributory and she reports no prior history of similar lesions. Fig. 1 She is a non-smoker. The lesion appeared slightly “bumpy” on the surface and was slightly reddish- to flesh-colored. It measured approximately 1 x 0.4 cm and was roughly rectangular in shape. Slight ery- thema was noted around the lesion. The lesion was entirely excised and submitted to the University of Florida College of Dentistry Oral Pathology Biopsy Service. The biopsy showed a papillary proliferation of epithelium with significantly thickened keratin with elongated rete ridges and foamy cells in the connec- tive tissue (Fig. 2). Question: Which of the following is the most likely diagnosis? A. Verrucous Leukoplakia B. Verruca Vulgaris C. Condyloma Acuminatum (venereal wart) D. Focal Epithelial Hyperplasia (Heck’s Disease) E.
