Cystoadenomas are considered uncommon neoplasms of epithelial salivary origin and are characterized by having multiple papillary projections and microcystic spaces recovered by cuboid and cilindric cells. Cystoadenoma is defined by the WHO as a salivary neoplasia very similar to Warthin´s tumour, but lacking lymphoid cells. The most common sites are the larynx, nasopharynx and lachrymal gland, although in some occasions these lesions can be found in the lips, buccal mucosa, palate and tonsillae. Thus 35% of cystoadenomas have minor salivary gland locations.

The symptoms and signs of congenital heart disease and patients who have prostheses and / or pacemakers placed must be assessed by the stomatologic dentistry specialist, for this they must be trained and prepared in their actions to avoid the risk of complications and in relation to the multidisciplinary team, since These patients are becoming more frequent. The stomatologic dentistry specialist in must apply a correct and attentive semiological examination, since in the same patient one or more syndromes and one or more pathologies can be presented KEY WORDS: dentistry, congenital heart disease, patient management ResumenLos síntomas y signos de las cardiopatías congénitas y pacientes que tienen colocadas prótesis y/o marcapasos deben ser valorados por el Odontoestomatólogo, para ello deben estar capacitados y preparados en su accionar para evitar el riesgo de complicaciones y en relación con el equipo multidisciplinario, ya que estos pacientes son cada vez más frecuentes. El Odontoestomatólogo debe aplicar un correcto y atento examen semiológico, ya que en un mismo paciente se pueden presentar uno o más síndromes y una o más patologías.

Ectodermal dysplasia is a rare inherited disorder distinguished by the not normal development of certain structures of ectodermal origin. The hypohydrotic ectodermal dysplasia has an autosomal recessive or X-linked inheritance, the latter being the most frequent. Patients with ectodermal dysplasia are patients who require a multidisciplinary approach to their treatment. It is of great importance that the patient is treated at an early age so that their self-esteem and their integration into society are not affected. Due to the oral characteristics of the DEH, the most common treatment is the elaboration of total prostheses, although the clinician may face various difficulties such as the poor development of alveolar processes and dry mouth, resulting from the poor or no salivary secretion.

Anaplastic large cell lymphoma (ALCL) is a rare subtype of T-cell lymphoma that may involve mucocutaneous sites, in primary form, or secondary to systemic disease. It is a systemic malignancy characterized by an extranodal phenotype that rarely occurs in the oral cavity as the first manifestation of acquired immunodeficiency syndrome. In the primary forms, ALCL stands out for its favorable prognosis, being important to differentiate them clinically from the secondary ones, which have a rapid and aggressive evolution.For its diagnosis, it requires a rigorous physical and clinical examination and a duly oriented anatomopathological and immunohistochemical evaluation. In the present work, a clinical case of ALCL secondary to HIV is presented, detailing clinical characteristics, anatomopathological description, immunohistochemical profile and evolution against treatment.

The most important potentially malignant lesion of labial squamous cell carcinoma affects actinic cheilitis. It found in people whose occupational activities related to chronic sun exposure. Squamous cell carcinoma (SCC) of the lip accounts for approximately 20% of all oral carcinomas with the lower lip more involved than the upper lip. It is more common in men, reaching its peak during its sixth and seventh decade, and is more frequent in the lower lip. KEY WORDS: actinic cheilitis, lip Carcinoma, oral diagnosis. Resumen la queilitis actínica es considerada la lesión potencialmente maligna más importante del carcinoma de células escamosas labial. Se encuentra comúnmente en individuos cuyas actividades ocupacionales están relacionadas con la exposición crónica al sol. El carcinoma de células escamosas (CCE) del labio representa aproximadamente 20% de todos los carcinomas orales con el labio inferior más comúnmente involucrado que el labio superior. Es más común en los hombres, alcanzando su punto máximo durante su sexta y séptima década, y es más frecuente en el labio inferior.
