Its prevalence has decreased notably since the introduction of multidrug therapy, but high numbers of cases are still recorded in countries in Southeast Asia, Latin America, Africa, the eastern Pacific, and the western Mediterranean. India is the country with the highest prevalence in the world, followed by Brazil.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1–4</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">Leprosy is a chronic infectious disease that mainly affects the skin and peripheral nerves, and is caused by the acid-fast bacteria <span class="elsevierStyleItalic">Mycobacterium leprae</span> and <span class="elsevierStyleItalic">Mycobacterium lepromatosis</span>. However, there can be considerable clinical variability among patients with leprosy, which can also affect the eyes, mucous membranes, and bones.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1–4</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Depending on clinical manifestations, the World Health Organization classifies leprosy into 2 broad categories: paucibacillary leprosy (1–5 lesions on the skin and/or 1 affected nerve trunk) and multibacillary leprosy (6 or more lesions on the skin and 2 or more affected nerve trunks).<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,4</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">The Ridley-Jopling classification<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> categorizes leprosy as tuberculoid (TT), borderline tuberculoid (BT), borderline-borderline (BB), borderline lepromatous (BL), lepromatous (LL), and indeterminate (IL) leprosy. If the patient lacks a cellular immune response, lepromatous leprosy develops. Patients with an effective cell-mediated immune response tend to develop the tuberculoid form. The borderline forms fall between the 2 aforementioned forms, occurring in patients with varying degrees of immune response. Lastly, indeterminate leprosy is considered the initial stage of the disease.<a class="elsevierStyleCrossRefs" href="#bib0015"><span class="elsevierStyleSup">3,5</span></a></p><p id="par0025" class="elsevierStylePara elsevierViewall">Leprosy reactions are immunological events that can occur before, during, or after treatment of the disease. Type 1 leprosy reactions are in turn divided into degradation reactions if there is a transition towards the lepromatous pole, and reversal reactions if there is a transition towards the tuberculoid pole. Type 2 leprosy reactions are subdivided into erythema nodosum leprosum, erythema polymorphic, and Lucio phenomenon or diffuse leprosy.</p><p id="par0030" class="elsevierStylePara elsevierViewall">The clinical variability of leprosy is determined by the tropism of the microorganism for the skin and peripheral nervous tissue, the cellular immune response, and the patient’s susceptibility to mycobacteria. Depending on the type of leprosy, cutaneous manifestations vary in terms of both lesion number and distribution.<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">7</span></a> The majority of patients develop LL, which is a multibacillary form, characterized by multiple nodules on the skin and mucosa (lepromas). The most common locations of these lesions are the face and pinna.<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">7</span></a> BL and BT leprosy are identified in a smaller proportion of patients. These patients are in an unstable stage, which eventually evolves to one pole or another on the leprosy spectrum. Clinically, BT leprosy presents as annular erythematous plaques with diffuse external borders and well-defined internal borders. The BL form is characterized by the presence of multiple hypopigmented papules, nodules, and infiltrated plaques.<a class="elsevierStyleCrossRefs" href="#bib0035"><span class="elsevierStyleSup">7,8</span></a> The higher frequency with which the BL and LL forms are identified can be attributed to an imbalance of the immune system at the moment of the clinical examination and the higher probability of polarizing to the LL form.<a class="elsevierStyleCrossRefs" href="#bib0045"><span class="elsevierStyleSup">9,10</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">Up to 30% of patients with a diagnosis of leprosy develop severe acute exacerbations either spontaneously or during treatment.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> These exacerbations are referred to as leprosy reactions and reflect a sudden deterioration of the immunological balance between the pathogen and the infected individual.

They are characterized by inflammation, pain in existing skin lesions, and neuritis. Type 2 leprosy reactions correspond to a systemic inflammatory response to immune complexes and are characterized by tender skin nodules, fever, and inflammation of organs (liver, lungs, joints, and eyes).<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> In accordance with our findings, it has been reported that leprous erythema nodosum is the most prevalent lesion in multibacillary leprosy patients and its presence, course, and persistence may be associated with odontogenic infections and periodontal disease.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">12</span></a></p><p id="par0045" class="elsevierStylePara elsevierViewall">It has been suggested that the clinical examination of patients diagnosed with leprosy should include the oral mucosa, as this may constitute a second route of mycobacterial transmission and infection. Oral lesions are usually asymptomatic and secondary to nasal changes. They are infrequent and are usually associated with LL or reactional phenomena. Another route of infection in the oral mucosa involves the hematogenous or lymphatic spread of the bacillus, favored by the temperature of the upper airways.</p><p id="par0050" class="elsevierStylePara elsevierViewall">The oral manifestations described to date are varied, and include macules, papules, nodules that can ulcerate or necrotize, and bone changes.<a class="elsevierStyleCrossRefs" href="#bib0060"><span class="elsevierStyleSup">12–14</span></a> Hypopigmentation of the mucosa, atrophy of the lingual papillae, and retraction of the uvula have also been described.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,13</span></a></p><p id="par0055" class="elsevierStylePara elsevierViewall">In contrast to leprosy-related skin lesions, which are well documented in the literature, few studies have characterized lesions in the oral cavity directly related with this disease, possibly due to their low prevalence.<a class="elsevierStyleCrossRefs" href="#bib0060"><span class="elsevierStyleSup">12–14</span></a> Furthermore, nonspecific lesions that occur in some leprosy patients can also manifest in the general population.<a class="elsevierStyleCrossRefs" href="#bib0075"><span class="elsevierStyleSup">15,16</span></a> The objective of the present study was to characterize oral lesions present in patients with Hansen disease.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0070">Material and Methods</span><p id="par0060" class="elsevierStylePara elsevierViewall">This cross-sectional observational study included 100 patients who were diagnosed with Hansen disease and treated at the Dr. Jacinto Convit Institute of Biomedicine in Caracas, Venezuela.
