RESUMO
The cutaneous and oral lesions related to nutritional deficiencies are scarcely reported. Micronutrient deficiencies may significantly affect mouth mucosa and skin, causing great morbidity. We report an extraordinary case with detailed clinical and microscopic findings affecting the oral cavity and skin. Physicians must be familiar with these manifestations to suspect the diagnosis.

Pemphigus is a group of autoimmune intraepidermal bullous diseases; being pemphigus foliaceus (PF) and pemphigus vulgaris (PV) the most common subtypes. Pustular variants are scarcely reported for both PV and PF. The purpose of this manuscript was to describe the clinical, microscopic and immunologic findings of an atypical case of PF presenting with pustules, including a review of the literature. PF is described as blisters and because this entity is rare, it is not known for the general medical community that they are other clinical features that can be seen as this one we present here with pustules.

Case 1 A 41-year-old man with human immunodeficiency virus (HIV) 1 diagnosed 16 years prior to his consultation was referred for an 8-month history of multiple painless lumps in his mouth. He had A2 status (CD4 cell count of 273 cells/mm3 and viral load of 43,000 copies/L) and was taking treatment with lamivudine/zidovudine (combivir) and efavirenz. Physical examination showed multiple small mucosal-colored and lobulated papulonodules located in the palate and lower gingiva and a whitish verrucous plaque on the lower labial mucosa (Figure 1a). The lesions were diagnosed clinically as focal epithelial hyperplasia (FEH) and further confirmed by classical histopathological findings (Figure 1b). He had previously received unspecified treatment; thus, topical 5% imiquimod cream was initiated every night. Mild erosion and ulceration developed in the upper labial mucosa, which were managed with lubrication (petrolatum ointment). After 2 weeks, all of the small lesions disappeared and the largest plaque resolved 1 week later (Figure 1c). A small residual mass in the area of biopsy, suggesting a scar, remained on the lower lip. The area was removed surgically and corresponded to fibrosis histologically, with no evidence of human papillomavirus (HPV) infection. CD4 cell count (694 cells/mm3) and viral load (<40 copies/L) did not show remarkable changes after imiquimod administration. No serious side effects were observed and the patient has remained free of disease after 1 year of follow-up.

A 65-year-old unemployed man, originally from Michoacán and currently living in Toluca, state of Mexico, presented for medical consultation for disseminated dermatosis in all body segments. The condition was limited to the head and neck, was bilateral and symmetrical, and was characterized by infiltrated and confluent erythematous-edematous plates of diverse diameter covering 90% of the upper and lower extremities (Figure 1). The ailment had 2 years' evolution and a progressive course. The patient was diagnosed in private practice as having atopic dermatitis. After exacerbation of symptoms, he was treated with deflazacort and hydroxychloroquine with no improvement. Results from lesion biopsies revealed sarcoidal granulomas and the patient was therefore referred to the dermatology department at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán for further study and treatment with the presumptive diagnosis of mycosis fungoides vs sarcoidosis.

BACKGROUND: The purpose of the study was to evaluate the clinical patterns of atrophy of the filiform papillae (FP) of the tongue and their relationship with the serum levels of iron and vitamin B12 among patients with systemic diseases, in a tertiary care center. METHODS: A cross-sectional, analytical, research study was designed. A systematic tongue examination was performed to evaluate the presence and clinical patterns of FP atrophy. We collected epidemiologic, clinical, and laboratory data. Statistical analysis included χ2 test, Fisher's exact test, Kruskal-Wallis test, and a logistic regression analysis. RESULTS: A total of 87 patients (83.9% females) were included [median age = 55 (range 20-89) years]. Endocrinopathy (60.9%) was the most frequent comorbidity. We found atrophy of the FP in 90.8% of the patients; the atrophy was mild in 83.5% of the cases, and severe in 16.5%. The most common atrophic patterns were as follows: focalized in 64 (73.6%) cases, "U"-shaped pattern in 60 (69%), and generalized in 30 (34.5%). Geographic tongue and median rhomboid glossitis were observed in 12 (13.8%) and 11 (12.6%) subjects, respectively. Lower titers of serum iron were detected in cases with focal (median = 71 vs. 110 mcg/dl) and generalized (median = 55 vs. 78 mcg/dl) FP atrophy (P = 0.03 and P = 0.009, respectively), than their counterparts. The presence of symptomatology was related to the focal pattern of atrophy (P = 0.038). CONCLUSIONS: A high frequency of filiform papillary atrophy of the tongue was observed in patients with comorbidities. Some atrophic patterns of the tongue were significantly associated with certain medical conditions.

Introduction: Nail changes in people living with human immunodeficiency virus (HIV) have been scarcely reported. The aim of this study was to establish the frequency and characteristics of nail alterations observed in adults with HIV infection in a third-level hospital in Mexico. Method: Observational and cross-sectional study carried out in 205 patients receiving care at the HIV/AIDS Clinic of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) in Mexico City. We performed a nail and iconographic assessment of both hands and toenails. We collected information of demographic and clinical variables, as well as drugs use, and antiretroviral treatment used by the participants through a questionnaire and from medical records. We performed direct cytological examinations and nail mycological cultures in participants with symptoms of onychomycosis. Results: The participants were predominantly male patients (91.2%), with a mean age of 41 (range 21-78) years, under antiretroviral therapy (91.2%), with a suppressed viral load (78.5%) and mean CD4+ lymphocyte count of 379.5 (range 20-1,162) cells/µL. Fitzpatrick's IV phototype was prevailing in the studied population (70%). Nail changes were documented in 72.2% of the patients; being pigmentary changes (37.1%) and trauma (30.7%) the most frequent. Onychomycosis was observed in 26.3%; with total dystrophic onychomycosis as the most frequent clinical variant (68.5%). We obtained fungal isolates in 59.3% of participants and Candida parapsilosis was the most frequent of these (37.5%). Conclusions: We observed a high prevalence of nail changes with very diverse etiology, as well as a variety of nondermatophytic yeasts and molds isolates associated with cases with onychomycosis. These findings reinforce and confirm the need for routine nail examination and stress the importance of medical personnel working with people living with HIV to have broad knowledge of nail pathology.
RESUMO
BACKGROUND: The mucocutaneous clinical profile of patients with amyloidosis in Latin America has been scarcely reported. OBJECTIVE: To describe clinical characteristics of skin and mucosal manifestations in systemic amyloidosis in a tertiary care center in Mexico City. METHODS: A cross sectional, retrospective analytical study was performed in patients with systemic amyloidosis over a 15-year period. Statistical analysis was done. RESULTS: A total of 98 patients were included (53 [54%] men; overall median age = 49 years old). Acquired systemic immunoglobulin light chain amyloidosis (AL) was the most common (49%) type, followed by (24.5%) wild-type transthyretin amyloidosis (H-TTR) (24.5%), undetermined cases (21%), and reactive systemic amyloidosis (AA) (6.1%). There were mucocutaneous manifestations in 34.7% of cases, mostly multiple myeloma-related AL (ALMM). Head and neck was the most often affected site (38.2%), and purpuric macules were the most common morphology (44.1%). Mucocutaneous affectation was predominantly observed in AL (50.0%) compared to other types (20.0%) of amyloidosis (P = 0.01). Likewise, involvement of organs was also significantly different among the diverse amyloidosis types (P < 0.05). The most frequent comorbidities were hypertension (18.3%) and hypothyroidism (18.3%). CONCLUSION: The clinical spectrum of manifestations in amyloidosis is wide. Involvement of skin and mucosa in amyloidosis is common; significant differences were observed concerning distribution of mucocutaneous amyloid manifestations among the different types of amyloidosis.

BACKGROUND: The development of squamous cell carcinoma from oral lichen planus is controversial. We report a case of intraoral squamous cell carcinoma, which presents together with lesions of oral lichen planus. The aim of this report was to analyze the problem to distinguish between the incipient changes of squamous cell carcinoma from the features described in oral lichen planus, in order to establish an accurate diagnosis of both entities. CLINICAL CASE: A 57-year old man with a history of smoking and chronic alcohol intake, who had an ulcerated tumor mass located in the tongue, and bilateral white reticular patches on buccal mucosa and borders of the tongue. The histopathological report was moderately differentiated invasive squamous cell carcinoma and lichen planus respectively. CONCLUSIONS: The premalignant nature of OLP is still indeterminate and controversial, this is primarily due to inconsistency in the clinical and histological diagnostic criteria used to differentiate cases of oral lichen planus from lichenoid reactions or other lesions causing intraepithelial dysplasia with high potentially malignant transformation. Oral lichenoid reactions are possibly most likely to develop malignant transformation as compared to the classic OLP lesions.
Introducción: el desarrollo de carcinoma escamocelular a partir del liquen plano bucal es controversial. Describimos un caso con carcinoma escamocelular intrabucal, que cursa con lesiones de liquen plano bucal y se analizan las dificultades para distinguir los cambios incipientes del carcinoma escamocelular de las lesiones por liquen plano intrabucales que lleven a establecer un diagnóstico certero de ambas entidades. Caso clínico: hombre de 57 años, con antecedente de tabaquismo y hábito alcohólico crónico, que presenta lesión tumoral ulcerada en borde lateral izquierdo de lengua y placas blancas reticulares bilaterales en mucosa yugal, bordes laterales y vientre de lengua. El reporte histopatológico fue de carcinoma escamocelular invasor moderadamente diferenciado y liquen plano respectivamente. Conclusiones: la naturaleza premaligna del liquen plano bucal es controvertida, esto por inconsistencia en los criterios diagnóstico clínicos e histológicos que permitan diferenciar los casos de liquen plano bucal de otras lesiones como las reacciones liquenoides o displasias intraepiteliales con alto potencial de malignización. Posiblemente las reacciones liquenoides bucales tienen un mayor riesgo de transformación maligna al compararse con el clásico liquen plano bucal.

An observational, prospective, longitudinal cohort study was performed at the AIDS Clinic of a tertiary care institution in Mexico City to determine the association of viral load (VL) and CD4+ lymphocyte kinetics with the development of oral candidosis (OC) and hairy leukoplakia (HL). Participants were HIV-infected adult subjects, without a history of or current OC or HL, not receiving HAART. Oral examinations were performed at baseline and every month for evidence of OC or HL; CD4+ and VL determinations were done at baseline, at 6-month intervals, when oral lesions were detected, and 2 months later. Affected subjects (OL group) by OC or HL had clinical intervals defined before (antecedent), during (concurrent), and after their development. In the nonaffected individuals (NA group), 6-month intervals were determined. Differences (changes) along the clinical and study intervals were calculated for CD4+ and VL. The median study time was 178 (range: 31-924) days; 99 patients were included. The 2-year cumulative incidence of either oral lesion was 54% (49.5% for OC and 33.2% for HL). In the OL group (31 patients) a progressive and continuous decrease of CD4+ was found in the antecedent interval followed by a significant increase in VL in the concurrent period. The NA group showed a significant fall in CD4+ by semester 3, without a significant rise of VL in the following semester. The effect of CD4+ remained significant in a multivariate analysis. This study has shown that the onset of OC and/or HL is heralded by the sequence of a sustained reduction of CD4+, followed by a sharp increase of VL. In the multivariate analysis, the decrease in CD4+ lymphocytes appeared to be the predominant factor predicting the appearance of these oral lesions. Their potential use as markers of a recent change in the immunologic and virologic status of HIV-infected individuals is emphasized.

The report describes an HIV/AIDS patient seen at a referral center in Mexico City, in whom a mycobacterial infection in the oral mucosa, probably tuberculosis (TB) was identified. The purpose is to describe the clinical and histological findings in an HIV-infected patient, who after being treated successfully for tuberculous lymphangitis 4 years ago, presented with a lingual ulcer as the only suggestive sign of recurrence of mycobacterial infection, probably M. tuberculosis. A 39-year-old man seen in the HIV clinic of the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" in Mexico City since 1991 for HIV infection. In 1999 the patient developed tuberculous lymphangitis; he was managed with a 4-drug regimen for 12 months, with improvement of local and systemic symptoms. In May of 2003, the patient presented a painful superficial lingual ulcer, 0.7 cm in diameter, well circumscribed, crateriform with slightly elevated, irregular and indurated borders, of 4 months duration. The histopathological examination showed chronic granulomatous inflammation with giant multinucleated cells, suggestive of mycobacterial infection, and recurrence of TB was considered. Rifampin, isoniazide, pyrazinamide, ethambutol and streptomycin were administered. The lingual lesion improved with partial healing at the first week and total remission at 45 days after the beginning of the antituberculous treatment. In June, 2003, the patient began highly active antiretroviral therapy (HAART) that included two NRTIs and one NNRTI. At 7 months of follow-up, the patient remains free of lingual lesions. The particularity of the present case is that the lingual ulcer was the only sign of infection by mycobacteria, suggestive of TB, in an HIV/AIDS patient that probably represented a recurrence of a previous episode.

BACKGROUND: Squamous cell papilloma is a benign mucosal disease associated with human papillomavirus. Its presence in human immunodeficiency virus (HIV)-infected patients has rarely been reported. Therapeutic modalities for oral squamous cell papilloma have limited success and recurrences are frequent in HIV-infected subjects. Imiquimod, is a topical immunomodulator successfully used in some human papillomavirus-related oral lesions. However, its use for oral squamous cell papillomas in HIV-infected individuals has never been described. OBSERVATIONS: We report two male adult patients with HIV-infection, B2 and C3 stage respectively, undergoing antiretroviral therapy, with multiple recalcitrant oral squamous cell papillomas, predominantly affecting the masticatory mucosa. These lesions were successfully treated with daily topical imiquimod 5% cream for a few weeks, with only mild and well-tolerated side effects. No recurrences were observed after a follow-up period of over 20 months. CONCLUSIONS: Our cases highlight the value of imiquimod for the non-invasive treatment of multiple persistent oral squamous cell papillomas in two HIV-infected patients.
RESUMO
In developing countries, the variations in the clinical spectrum of human immunodeficiency virus (HIV)-related oral lesions over time, and the possible effects of antiretroviral therapy, have not been described. In this study we evaluate the clinical spectrum of oral lesions in a series of HIV-infected patients when first examined at the acquired immunodeficiency syndrome (AIDS) clinic of a tertiary care institution in Mexico City, Mexico, and the changes observed over 12 years. All HIV-infected adult patients had an oral examination performed by specialists in oral pathology and medicine who used established clinical diagnostic criteria for oral lesions. Four periods were defined according to the evolving pattern of antiretroviral use: the first 2 were before the introduction of highly active antiretroviral therapy (HAART) and the last 2 were during more established use of HAART. For the statistical analysis the chi-square test for contingency tables and the chi-square test for trend were utilized. For dimensional variables, except age, the Kruskal-Wallis or Mann-Whitney rank sum tests were used when applicable and trend was tested with the Spearman correlation coefficient. Age was tested through analysis of variance (ANOVA) and linear regression analysis. Alpha value was set at p = 0.05 for each test. In the 12-year study, 1,000 HIV-infected patients were included (87.9% male). At the baseline examination, oral lesions strongly associated with HIV were present in 47.1% of HIV-infected patients. Oral candidosis (31.6%), hairy leukoplakia (22.6%), erythematous candidosis (21.0%), and pseudomembranous candidosis (15.8%) were the most frequent lesions. Oral Kaposi sarcoma (2.3%), HIV-associated periodontal disease (1.7%), and oral non-Hodgkin lymphoma (0.1%) were less frequent. HIV-related oral lesions decreased systematically-by half during the course of the 4 study periods (p < 0.001). Except for Kaposi sarcoma, all oral lesions strongly associated with HIV showed a trend to decrease significantly during the study period. No apparent variation in the occurrence of salivary gland disease or human papillomavirus-associated oral lesions was found. A significant trend to a lower prevalence was observed in the group of patients who were already taking antiretroviral therapy, non-HAART and HAART (p < 0.001 and p = 0.004, respectively). Only a discrete reduction, barely significant, was noted among untreated patients (p = 0.060). By Period IV (1999-2001), those who received HAART showed the lowest prevalence of oral lesions strongly associated with HIV (p < 0.001). Patients with oral lesions strongly associated with HIV had significantly lower median CD4+ counts and higher viral loads than those without oral lesions strongly associated with HIV (p < 0.001 and p = 0.005, respectively). When CD4+ counts were correlated with prevalence of oral candidosis, a consistently negative association was found; this association prevailed even after the study group was partitioned according to period. In this selected cohort of 1,000 patients with HIV infection, the clinical spectrum of HIV-related oral lesions has changed over the 12-year study, with a decreased prevalence of most oral lesions. Our findings probably represent improvements in medical care of HIV-infected persons, earlier detection of HIV-infected patients at the AIDS clinic, the increasing use of prophylactic drugs to prevent secondary AIDS-related opportunistic infections, and, perhaps most important, the availability of potent antiretroviral therapy in recent years, since the introduction of HAART.

BACKGROUND: Chronic pruritus is occasionally intractable; it has different etiologies and affects life quality. Our objective was to describe the prevalence of pruritus in newly-arrived patients at the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán". METHODS: A cross-sectional study was developed in newly-arrived patients. We conducted previous surveys in order to identify those patients with pruritus. With a second survey we inquired their sociodemographic traits, comorbidities, drugs being administered, the characteristics of pruritus, and the impact on the patient's quality of life. RESULTS: Of 554 previous surveys, we identified 70 cases of chronic pruritus. Most of the cases were women in their middle ages (42 years). According to the classification of pruritus, 67.2 % was associated to the underlying disease, 14.8 % was related to dermatologic condition, 3.3 % to pharmacological effects, 4.9 % to other conditions, and 9.8 % was idiopathic. Life quality was not affected in 7 %, was minimally affected in 28 %, and was mild to severe in 26 %. CONCLUSIONS: Chronic pruritus was highly prevalent in the Institute. It was mainly associated with the underlying disease, and affected significantly the quality of life. More studies are needed for better understanding its pathophisiology. Furthermore, new treatments will be available to control pruritus, bringing a better quality to those affected patients.
INTRODUCCIÓN: en ocasiones, el prurito crónico es intratable y afecta la calidad de vida. El objetivo de esta investigación fue describir la prevalencia de prurito en pacientes que acudieron a consulta por primera vez al Instituto Nacional de Nutrición y Ciencias Médicas "Salvador Zubirán". MÉTODOS: estudio observacional y transversal. Se realizaron pre-encuestas a pacientes de nuevo ingreso, para identificar a quienes tenían prurito. Se investigaron características sociodemográficas, comorbilidades, fármacos de base, características del prurito y el impacto que tenía en la calidad de vida. RESULTADOS: Se realizaron 554 pre-encuestas, en las cuales se identificaron 70 casos (11 %). El prurito crónico predominó en mujeres; la edad promedio fue de 42 años. Según la clasificación del prurito, 67.2 % estaba relacionado con la enfermedad de base, 14.8 % con enfermedad dermatológica, 3.3 %, con fármacos, 9.8 % era idiopático y 4.9 % se debía a otros motivos. La calidad de vida no se afectó en 7 %, en 28 % los efectos fueron mínimos y en 26 %, de intensidad moderada a severa. CONCLUSIONES: el prurito crónico fue altamente prevalente en el Instituto, se relacionó principalmente con la enfermedad de base y afectó significativamente la calidad de vida. Con el estudio de este padecimiento se dilucidará su etiopatogenia y los tratamientos que permitan controlarlo y brindar mejor calidad de vida de los pacientes afectados.

Background. Oral lesions may constitute the first clinical manifestation in secondary syphilis, but detailed descriptions in HIV-infected individuals are scarce. Objective. To describe the clinical characteristics of oral secondary syphilis in HIV-infected patients and its relevance in the early diagnosis of syphilis. Methods. Twenty HIV/AIDS adult subjects with oral secondary syphilis lesions presenting at two HIV/AIDS referral centers in Mexico City (2003-2011) are described. An oral examination was performed by specialists in oral pathology and medicine; when possible, a punch biopsy was done, and Warthin-Starry stain and immunohistochemistry were completed. Intraoral herpes virus infection and erythematous candidosis were ruled out by cytological analysis. Diagnosis of oral syphilis was confirmed with positive nontreponemal test (VDRL), and, if possible, fluorescent treponemal antibody test. Results. Twenty male patients (median age 31.5, 21-59 years) with oral secondary syphilis lesions were included. Oral lesions were the first clinical sign of syphilis in 16 (80%) cases. Mucous patch was the most common oral manifestation (17, 85.5%), followed by shallow ulcers (2, 10%) and macular lesions (1, 5%). Conclusions. Due to the recent rise in HIV-syphilis coinfection, dental and medical practitioners should consider secondary syphilis in the differential diagnosis of oral lesions, particularly in HIV-infected patients.
RESUMO
OBJECTIVE: To estimate the prevalence of oral lesions and its association with HIV serological status. MATERIAL AND METHODS: A cross-sectional descriptive study was conducted between 1998 and 1999 in Mexico City, among 512 subjects attending two information centers of Centro Nacional para la Prevención del VIH/SIDA e ITS (CONASIDA, National Center for Prevention of HIV/AIDS and Sexually Transmitted Infections) for HIV serologic testing. The oral examination was performed without knowledge of the HIV status. Statistical analysis was conducted using Student's t test, Fisher's exact test and the chi 2 test; odds ratios and 95% CI were also calculated. RESULTS: A total of 512 individuals were examined, 68 of whom were HIV-positive. HIV-related oral lesions (OL), were evident in 65% (44/68) of the HIV-positive individuals; 95% of them consisted in oral candidosis (OC) and hairy leukoplakia (HL). OC and HL were strongly associated with seropositivity to HIV. CONCLUSIONS: OC and HL were the oral lesions most strongly associated to HIV seropositivity.

Se describe un paciente con VIH/SIDA en el que se identificó una infección por micobacteria en la mucosa bucal, probablemente tuberculosis, en un centro de referencia para VIH/SIDA de la Ciudad de México. El propósito del presente informe es describir los hallazgos clínicos e histológicos en un paciente con VIH/SIDA, quien después de haber sido tratado exitosamente para tuberculosis ganglionar 4 años antes, presentó una úlcera lingual como único signo que sugirió recurrencia de infección por micobacteria, probablemente tuberculosis. Hombre de 39 años de edad, atendido desde 1991 en el Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, por el diagnóstico de infección con VIH. En 1999, el paciente presentó tuberculosis ganglionar, recibiendo tratamiento antifímico con involución de las adenopatías y desaparición de los síntomas sistémicos. En mayo del 2003 acudió a consulta por presentar una úlcera superficial en lengua, dolorosa, de 4 meses de evolución, de 0.7 cm. de diámetro, bien circunscrita, crateriforme, con bordes ligeramente elevados, irregulares e indurados. El estudio histopatológico mostró inflamación granulomatosa crónica con células gigantes multinucleadas sugestivas de infección por micobacteria, lo cual hizo pensar en recurrencia de tuberculosis, por lo que se indicó rifampicina, pirazinamida, etambutol y estreptomicina. En junio del 2003 el paciente inició TARAA, que incluyó dos ITRAN y un ITRNN. La lesión lingual evolucionó favorablemente, con cicatrización parcial a la primera semana y remisión total a los 45 días del inicio del tratamiento antifímico; a los 7 meses de seguimiento permanece sin lesión. El presente caso tiene la particularidad de que la úlcera lingual fue la única manifestación de infección por micobacteria, sugestiva de tuberculosis, en un paciente con VIH/SIDA, que pudo ocurrir como resultado de la recurrencia del episodio previo de TB ganglionar

Rifampin, isoniazide, pyrazinamide, ethambutol and streptomycin were administered. The lingual lesion improved with partial healing at the first week and total remission at 45 days after the beginning of the antituberculous treatment. In June, 2003, the patient began highly active antiretroviral therapy (HAART) that included two NRTIs and one NNRTI. At 7 months of follow-up, the patient remains free of lingual lesions. The particularity of the present case is that the lingual ulcer was the only sign of infection by mycobacteria, suggestive of TB, in an HIV/AIDS patient that probably represented a recurrence of a previous episode

OBJECTIVE: To estimate the prevalence of oral lesions and its association with HIV serological status. MATERIAL AND METHODS: A cross-sectional descriptive study was conducted between 1998 and 1999 in Mexico City, among 512 subjects attending two information centers of Centro Nacional para la Prevención del VIH/SIDA e ITS (CONASIDA, National Center for Prevention of HIV/AIDS and Sexually Transmitted Infections) for HIV serologic testing. The oral examination was performed without knowledge of the HIV status. Statistical analysis was conducted using Student's t test, Fisher's exact test and the chi 2 test; odds ratios and 95 CI were also calculated. RESULTS: A total of 512 individuals were examined, 68 of whom were HIV-positive. HIV-related oral lesions (OL), were evident in 65 (44/68) of the HIV-positive individuals; 95 of them consisted in oral candidosis (OC) and hairy leukoplakia (HL). OC and HL were strongly associated with seropositivity to HIV. CONCLUSIONS: OC and HL were the oral lesions most strongly associated to HIV seropositivity.
