RESUMEN

Several oral lesions related to COVID-19 have been described in the scientific literature. The COVID-19 pandemic highlighs importance of supportive protocols, which can reduce the inflammation and aid in tissue repair in severe cases. Photobiomodulation therapy (PBMT) alone or in combination with antimicrobial photodynamic therapy (aPDT) can be used to manage orofacial lesions in confirmed cases of COVID-19. Here, we sought to describe the clinical presentation and specificities of three cases in which aPDT and PBMT were used to manage orofacial lesions in patients with COVID-19. The laser protocols were effective with improvement of the orofacial lesions within a few days.

RESUMEN

Metastasis to the oral cavity are rare, representing only 1% of all oral malignancies, and originate from various sites such as the breast, prostate, lung and kidney. Clinically, they can simulate reactive and inflammatory lesions common in the oral cavity, and the clinical and microscopic diagnosis of these metastasis is a challenge. In this article, we report two new cases of esophageal and lung metastasis to oral tissues, highlighting their clinical characteristics and the process of diagnostic elucidation. We emphasize the importance for clinicians to consider the possibility of metastatic lesions in the oral cavity in patients previously diagnosed with malignant lesions in distant tissues and organs. Key words:Diagnosis, esophageal squamous cell carcinoma, adenocarcinoma of lung, oral cavity, metastasis.

RESUMEN

Objective: The objective of this study was to report the application of photobiomodulation therapy (PBMT) in the treatment of two patients diagnosed with acute cervical radiodermatitis (RD) induced by radiotherapy. Background data: An undesirable effect of radiotherapy, RD often poses a limitation to the continuity of treatment that can negatively affect the control and prognosis of the disease. RD is frequently associated with pain and aesthetic impairment and can significantly influence quality of life. Many agents used to prevent and treat RD do not have sufficient scientific evidence to support its use. Materials and methods: In both clinical cases, the patients presented RD degree 3 and were in drug treatment, with no satisfactory response, and PBMT was started. Two diode lasers were used, with a dose of 35.71 J/cm2, 10 sec/point, 100 mW of power, and a beam area of 0.028 cm2 and dose of 27.77 J/cm2, 25 sec/point, 40 mW, and 0.036 cm2 beam area. Both lasers were applied at the wavelength of red, daily, in contact and perpendicular to the skin, to deliver 1 J/point/1.5 cm, which covered the entire area affected with RD. Results: The PBMT made possible an expressive improvement in the healing process and reduction of painful symptoms associated with RD. Conclusions: Although PBMT facilitated healing and reduced pain experienced with RD, randomized controlled trials are needed to evaluate all of its possible benefits.

RESUMEN

Introdução: A Síndrome de Stevens-Johnson é uma reação rara que se manifesta por exantema que evolui para um extenso deslocamento epidérmico. Na maioria dos casos, há o surgimento de lesões dolorosas em mucosa oral, que podem reduzir a ingestão de nutrientes e dificultar a higiene bucal. A terapia de fotobiomodulação pode ter um importante papel antálgico, na modulação da inflamação e na cicatrização dessas lesões. Objetivo: Relatar um caso clínico no qual as lesões orais da Síndrome de Stevens-Johnson foram tratadas com o auxílio da terapia de fotobiomodulação. Relato de caso: Paciente de 17 anos, do sexo feminino, com diagnóstico de síndrome de Stevens-Johnson, apresentava-se com edema labial, úlceras orais, febre e odinofagia intensa, com tolerância apenas para dieta líquida. Encontrava-se com redução da ingestão alimentar, sem comunicação oral eficiente e com interrupção da higiene bucal devido a dor intensa. A terapia de fotobiomodulação foi utilizada no tratamento das lesões orais. Conclusão: A terapia de fotobiomodulação auxiliou na redução da dor, favoreceu a ingestão de alimentos por via oral e reduziu o tempo de cicatrização das lesões.

Introduction: Stevens-Johnson Syndrome is a rare reaction manifested by a rash that evolves into extensive epidermal dislocation. In most cases there are painful oral mucosal lesions that can reduce nutrient intake and make oral hygiene difficult. Photobiomodulation therapy can play an important antalgic role in modulating inflammation and healing these lesions. Objective: To report a clinical case in which Stevens-Johnson Syndrome oral lesions were treated with the aid of photobiomodulation therapy. Case Report: A 17-year-old female patient diagnosed with Stevens-Johnson syndrome presented with lip edema, oral ulcers, fever, and severe odynophagia, tolerating only a liquid diet. She experienced reduced food intake, no efficient oral communication, and an interruption of oral hygiene due to intense pain. Photobiomodulation therapy was requested to treat the oral lesions. Conclusion: Photobiomodulation therapy helped reduce pain, favored oral food intake, and reduced lesion healing time.

RESUMEN

RATIONALE: Oral metastases occur more commonly in bone, but can also manifest in soft tissues and eventually resemble a reactive lesion. Few cases of oral metastases mimicking reactive lesions in soft tissues have been reported to date. PATIENT CONCERNS: We report a metastasis of gastric carcinoma (GC) to the oral mucosa without bone involvement in a 43 yom clinically and microscopically mimicking a reactive lesion. The patient related that the lesion had 1 month of evolution, and the ulcerated area suggested the lesion was related to trauma. DIAGNOSES: The histopathological examination of the lesion revealed an exuberant granulation tissue with few neoplastic cells, and the initial diagnosis of pyogenic granuloma was considered. In a second analysis, clusters of clear cells morphologically similar to degenerating mucous cells or macrophages, positive for Cytokeratin (CK)-20, and CDX2 were found. At the moment, it was confirmed the presence of a primary GC in the patient. INTERVENTIONS: A palliative radiotherapy/chemotherapy was started. OUTCOMES: However, the patient died 3 months after the diagnosis of oral metastasis. LESSONS: This report highlights the importance of careful clinical and microscopic examinations in cases of oral metastasis that may mimic a reactive lesion.
