Combination of phototherapy for treatment of labial necrotizing lesion: case report

Lip necrotizing lesions are painful, complex to heal, and negatively impact the patient's orofacial condition. The present study reports a clinical case of a necrotizing lesion on the lower lip in a 38-year-old male patient, previously healthy, five days after receiving the first dose of the SARS-COV-2 vaccine, with an initial diagnosis of labial herpes zoster, with secondary infection and unsatisfactory response to clinical treatment. After debridement of the necrotic tissue, followed by a combination of antimicrobial photodynamic therapy (aPDT), photobiomodulation therapy (PBMT) and hydrofiber dressing with silver, the patient evolved with complete healing of the lip lesion and satisfactory restoration of orofacial functions after 7 days. According to the present case report, this combination of phototherapy modalities suggests to be a promising tool for the treatment of necrotizing labial lesions.

Clinicopathological Analysis of Actinic Cheilitis: A Systematic Review with Meta-analyses.

BACKGROUND: This systematic review aimed to conduct a complete investigation of the demographic aspects, clinicopathological features, degrees of epithelial dysplasia, and malignant transformation rate of actinic cheilitis. METHODS: The study was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the International Prospective Register of Systematic Reviews (CRD42020201254). A search without year and language restrictions was performed using PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature. Studies that provided information on patients with actinic cheilitis were included, excluding those with general information on other diseases or other types of cheilitis. Risk of bias was explored using the Joanna Briggs Institute tool. Narrative and quantitative data syntheses were performed using meta-analyses and subgroup analyses. Association tests were also performed. RESULTS: Thirteen studies (728 patients) were included. The most prevalent clinical signs were dryness (99%), blurred demarcation between the lip vermilion and skin (82%), scaling (69%), and atrophy (69%). Regarding epithelial dysplasia, a prevalence of mild dysplasia (34.2%), followed by moderate (27.5%), and severe (14.9%). The malignant transformation rate was 14%. Crusts, ulcerations, and erythematous areas were associated with lip carcinoma (p < 0.001), and scaling was associated with actinic cheilitis (p < 0.001). CONCLUSIONS: This study revealed several features of actinic cheilitis, providing an overview of the disease. It is suggested that new studies help develop policy guides for the standardization of clinical criteria, enabling more rigorous and homogeneous analysis of actinic cheilitis.

Photobiomodulation and Antimicrobial Photodynamic Therapy for Oral Ulcers in a Patient With Thrombocytopenia Following Bone Marrow Transplantation.

Introduction: Thrombocytopenia is usually seen after allogeneic hematopoietic stem cell transplantation (HSCT) and may favor the development of oral bleeding, infections, and ulcerations. Case Report: A patient with chronic myelomonocytic leukemia had been submitted to allogeneic HSCT. Within a few days, she developed severe thrombocytopenia and an extensive ulcerative area comprising both lips, which bled spontaneously, as well as smaller ulcers on the tongue mucosa. The lesions were managed using a combination of phototherapies (photobiomodulation and antimicrobial photodynamic therapies), totalizing 4 laser sessions. After 4 days, there was an important reduction in the severity of the lesions, with spontaneous disappearance of the crusts and reepithelization. Conclusion: The proposed combination of phototherapies would be a suitable therapeutic modality for the management of oral lesions related to platelet disorders induced by oncologic treatments.

Caliber-persistent labial artery: report of 3 cases

Abstract The caliber-persistent labial artery is a vascular anomaly in which a primary arterial branch penetrates into the submucosal tissue without reduction in diameter. Most lesions are benign and do not require treatment, except for complications and/or on patient demands. In this way, noninvasive diagnostic tools are preferred such as high-resolution and color Doppler ultrasonography which allow direct observation of the lesion, assessing its exact location and diameter at every axis, as well as the blood flow velocity. An excisional biopsy of these lesions or even their surgical extirpation could have a fatal outcome with profuse bleeding.

Técnica de Kapetansky-Juri modificada para la corrección de defectos labiales en silbido / Modified Kapetansky-Juri technique to correct whistling lip defects

RESUMEN La deformidad en silbido es uno de los defectos residuales más frecuentes entre pacientes operados de hendiduras congénitas del labio superior. La técnica de Kapetansky-Juri ha permitido corregir los defectos en silbido (moderados y graves). Se presentó una paciente de 16 años de edad operada de una hendidura bilateral labio palatina; a causa de esta hipoplasia regional y tras el proceso de crecimiento y desarrollo craneofacial, persistió la insuficiencia del prolabio como un defecto en silbido moderado. La paciente fue tratada con la técnica de Kapetansky-Juri con una pequeña modificación, lo que permitió, no solo dar volumen al prolabio, sino también un intento en la corrección del arco de Cupido. Los resultados alcanzados fueron satisfactorios y se corresponden con los objetivos finales de toda cirugía reparadora de las hendiduras labio alveolo palatinas.

ABSTRACT Whistling deformity is one of the most frequent residual defects in patients operated on for congenital clefts of the upper lip. Kapetansky-Juri technique has made it possible to correct whistling defects (moderate and severe). We present a 16-year-old female patient operated on a bilateral cleft lip and palate; given this regional hypoplasia and after the process of growth and craniofacial development, insufficiency of the prolabium persisted as a moderate whistling defect. She was treated with the Kapetansky-Juri technique with a small modification, allowing us not only to give volume to the prolabium, but also an attempt to correct the Cupid's bow. The achieved results were satisfactory and correspond to the final objectives of all reconstructive surgery of the cleft lip and palate.

EBV-negative lymphoepithelial-like carcinoma of the lower lip

Lymphoepithelial-like carcinoma (LEC) is a rare malignant neoplasm, which can be associated with Epstein-Barr virus (EBV) infection. Histologically, LEC is an undifferentiated carcinoma with an intermixed reactive lymphoplasmacytic infiltrate. LEC appears to be an uncommon tumor type of lip carcinoma. An 82-year-old white woman presented a lesion on her lower lip that developed over the last year. The lesion was characterized by ulceration with flat edges, hardened base, painful, and absence of regional lymphadenopathy. Microscopical analysis evidenced an intense inflammatory infiltrate, composed of lymphoplasmacytic cells, associated with scarce pleomorphic epithelial cells. Immunohistochemistry highlighted the LEC cells with strong expression of pan-CK AE1/AE3, EMA, p63, and p53. CD138 was also faintly positive. Ki-67 was >85%. In situ hybridization analysis did not show evidence of EBV. A diagnostic of EBV-negative LEC was made. We present an uncommon type of lip carcinoma, which can represent a diagnostic challenge for clinicians and pathologists.

Plasma cell cheilitis: the diagnosis of a disorder mimicking lip cancer.

Plasma cell cheilitis (PCC) is an inflammatory disorder of unknown etiology that affects the lip. It is characterized histologically by a dense infiltrate of plasma cells with a variety of clinical features. The response to different therapeutic modalities is controversial, especially regarding the effectiveness of corticosteroids. We present a case of a 56-year-old Caucasian man with a painful ulcerated and crusted area in the lower lip, resembling a squamous cell carcinoma or actinic cheilitis. Topical corticosteroid was used for one week, which resulted in partial regression and motivated a biopsy. The histological examination provided the diagnosis of PCC. The patient has been disease-free for six months. We also provide a discussion on the criteria of differential diagnosis and management of this rare condition.

Differential Diagnosis of Cheilitis - How to Classify Cheilitis?

Although cheilitis as a term describing lip inflammation has been identified and recognized for a long time, until now there have been no clear recommendations for its work-up and classification. The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis. However, variable nomenclature is used and subtypes are grouped and named differently. According to our experience and clinical practice, we suggest classification based on primary differences in the duration and etiology of individual groups of cheilitis, as follows: 1) mainly reversible (simplex, angular/infective, contact/eczematous, exfoliative, drug-related); 2) mainly irreversible (actinic, granulomatous, glandular, plasma cell); and 3) cheilitis connected to dermatoses and systemic diseases (lupus, lichen planus, pemphi-gus/pemphigoid group, -angioedema, xerostomia, etc.).

Prevalence of and factors associated with actinic cheilitis in extractive mining workers

Abstract The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student's, ANOVA one-way, Fisher's exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Resumo O objetivo foi determinar a prevalência de queilite actínica entre os trabalhadores extrativistas minerais e os fatores associados a esta lesão, principalmente a relação da aparência clínica da lesão com o tempo de exposição ocupacional à luz solar. Foi realizado um estudo transversal, entre 2014 e 2015, em Dona Inês / PB, localizado no Nordeste do Brasil. Foram aplicados um exame clínico, registro fotográfico e um questionário a 201 trabalhadores extrativistas minerais. Realizaram-se os testes "t" student, ANOVA, Exato de Fisher e Qui-quadrado de Pearson, o nível de significância foi de 5%. Observou-se alta prevalência de queilite actínica (38,8%). A duração da exposição ocupacional à luz solar, em meses, (169,63 ± 112,68, p = 0,002) foi associada à presença de queilite actínica. Estes trabalhadores eram, em sua maioria, brancos (p<0.001) com idade média de 37.41±12.15 anos (p=0.004). O tempo de exposição ocupacional à luz solar foi significativo em relação às seguintes características clínicas: atrofia (225,75 ± 97,31; p = 0,024); perda da demarcação entre o vermelhão do lábio e a borda da pele (186,68 ± 113,15; p = 0,032); Fissuras verticais (210,09 ± 123,07; p = 0,046); Manchas brancas e vermelhas (199,51 ± 91,80; p = 0,004); Consistência dura do lábio (225,81 ± 122,34; p = 0,012). Conclui-se que a prevalência de queilite actínica foi alta. A idade e a etnia foram fatores associados a presença de queilite actinica. Os participantes que haviam trabalhado pelo menos 185 meses (aproximadamente 15 anos) sob exposição ao sol, apresentaram manifestações clínicas graves da queilite actínica.

Evaluation the efficacy of trichloroacetic acid (TCA) 33% in treatment of oral retinoid-induced cheilitis compared with placebo (Vaseline): a randomized pilot study.

BACKGROUND: Oral Isotretinoin (13-cis-retinoic acid) is a gold standardtreatment for severe forms of acne with cheilitis as a most frequent complication. We designed this novel study to investigate the therapeutic effect of trichloroacetic acid (TCA) 33% as compared with placebo to treat cheilitis. METHODS: In this pilot study, 90 acne vulgaris patients between 18 and 50 years, who referred dermatologic clinic with cheilitis, were assigned to either case (TCA) or control (Vaseline) group using permuted-block randomization from 2013 to 2015 with data analysis in 2016. Patients had follow-up visits after 2 and 6 weeks, at which their lesions were photographed. Two blinded expert dermatologists recorded physician International global score for each image. RESULTS: Ninety eligible patients were randomly allocated into two groups. This included 45 patients in each group. At the end of follow-up, 44 patients in the intervention group and 37 patients in control group completed the final assessment. Compared to the control group, the TCA group had a greater reduction in the mean ICGS value from baseline to Week 6 (mean difference 2.59 points, p < .0001). CONCLUSIONS: TCA can be considered as a good strategy in improvement of cheilitis to isotretinoin therapy.

Verruciform Xanthoma of a Lower Lip Lesion: A New Case and Review of the Literature.

A non-smoking man in his seventh decade presented with a lesion he had had for about 5 years on the right external surface of the lip 1 mm from the vermilion border. On physical examination, a yellowish-coloured, non-tender, verrucous mass of 0.5 × 0.7 cm was observed. A histopathological examination of the first 3-mm punch biopsy was non-diagnostic. The histopathological evaluation of a second, 5-mm-deep punch biopsy made by a pathology expert in oral lesions revealed a diagnosis of verruciform xanthoma. The key to the diagnosis of verruciform xanthoma is to recognize xanthoma cells. However, these cells may be insufficient in number in small and superficial biopsy material and overlooked by a pathologist especially when lacking knowledge of this uncommon lesion. Verruciform xanthoma of the lower lip at the vermilion border is an extremely rare entity described in 5 cases worldwide to date. We aimed to bring verruciform xanthoma to readers' attention for a differential diagnosis of lower lip diseases and to prevent overdiagnosis and overtreatment of this lesion unfamiliar to otorhinolaryngologists.

Queiloplastia primária unilateral através da técnica de Fisher / Unilateral primary lip repair by Fisher technique

Introdução: As fissuras labiais são alterações congênitas que decorrem da não fusão dos processos nasais medianos com os processos nasais laterais, sendo sua ocorrência em aproximadamente 1:550 nascidos vivos. Essas fissuras podem apresentar-se bilaterais ou unilaterais nos lábios e acompanhadas ou não de fenda palatina. A cirurgia primária para reparação do lábio fissurado unilateral vem sendo descrita por diversas técnicas na literatura e geralmente envolve rotações de retalho e deixam cicatrizes visíveis bem como encurtamento do vermelhão do lábio. A técnica de Fisher foi proposta para resultar em uma cicatriz menos visível, em linha reta na região do filtro labial, colocando-a em uma região mais anatômica e simplificando a cirurgia. O objetivo deste artigo é mostrar um caso clínico de queiloplastia primária unilateral, utilizando a técnica de Fisher. Relado de Caso: Paciente CDSS, 8 meses de idade, portador de fissura lábio-palatina unilateral do lado esquerdo. A cirurgia do lábio foi realizada em ambiente hospitalar sob anestesia geral e a técnica utilizada foi a de Fisher. No acompanhamento de 30 dias o paciente apresentou-se com uma cicatriz bastante discreta, posicionada simetricamente em relação ao filtro labial do lado oposto. Conclusão: A técnica de Fisher mostrase como ótima opção para o tratamento de fissuras labiais unilaterais, pois proporciona uma excelente estética, a técnica cirúrgica é relativamente simples e acompanhada de bons resultados funcionais

Introduction: Cleft lip is a congenital abnormality arising from no merger of the median nasal processes with the lateral nasal processes, and their occurrence is approximately 1 in 550 live births. These clefts may present bilateral or unilateral lips and with or without cleft palate. The primary surgery for repair of unilateral cleft lip has been described by several techniques in literature and usually involves retail rotations and leave visible scars and lip vermilion shortening. Fisher technique has been proposed to result in a less visible scar, straight in the philtrum region placing it in a more anatomical region and simplifying the surgery. The purpose of this article is to show a case of unilateral primary lip repair using the Fisher technique. Case Report: Patient CDSS 8 months old has an unilateral cleft lip and palate on the left side. The lip surgery was performed in a hospital under general anesthesia and the technique used was Fisher. In the following 30 days, the patient is presented with a very slight scar, positioned symmetrically in relation to the philtrum of the opposite side. Conclusion: Fisher technique is shown as great option for the treatment of unilateral cleft lip, it provides an excellent aesthetic, the surgery technique is relatively simple and accompanied by good functional results

A 15-year retrospective study of 160 cases of benign lip lesions.

OBJECTIVE: This study aimed to describe the results of a retrospective analysis of a specific cohort of patients with benign lip lesions encountered in the last 15 years in the School of Medicine at Karadeniz Technical University. METHOD: A total of 312 patients were managed for lip lesions during the period 2000-2014. Data from 160 samples of benign lip biopsies were retrieved from the pathology laboratory records. RESULTS: The study group included 20 different histopathological types of lesions, with mucocele being the most frequent lesion (43.13 per cent). The other frequent lesions were chronic inflammatory infiltrate (11.25 per cent), intradermal naevus (5.63 per cent), pyogenic granuloma (5.63 per cent), fibroma (5 per cent) and papilloma (5 per cent). Mucocele was significantly more common in younger patients (p < 0.001). CONCLUSION: Knowledge of the epidemiology and distribution of oral mucosal lesions is essential to promote early diagnosis and treatment. Further epidemiological studies exploring the causal relationships and risk factors for lip lesions are necessary for a better understanding of lip diseases.

Actinic prurigo of the lip: Two case reports.

Actinic prurigo is a photodermatosis that can affect the skin, conjunctiva and lips. It is caused by an abnormal reaction to sunlight and is more common in high-altitude living people, mainly in indigenous descendants. The diagnosis of actinic prurigo can be challenging, mainly when lip lesions are the only manifestation, which is not a common clinical presentation. The aim of this article is to report two cases of actinic prurigo showing only lip lesions. The patients were Afro-American and were unaware of possible Indian ancestry. Clinical exam, photographs, videoroscopy examination and biopsy were performed, and the diagnosis of actinic prurigo was established. Topical corticosteroid and lip balm with ultraviolet protection were prescribed with excellent results. The relevance of this report is to show that although some patients may not demonstrate the classical clinical presentation of actinic prurigo, the associated clinical and histological exams are determinants for the correct diagnosis and successful treatment of this disease.

Histopatologia da forma labial cicatricial de Keith / Histopathology of Keith`s lip scar

O estudo da etiologia das formas congênitas ditas cicatriciais, que incluem bandas cicatriciais congênitas e formas cicatriciais das fissuras labiais, apresenta diversas teorias, que fundamentam seu aparecimento, porém não justificam todos os aspectos envolvidos nessas malformações. Neste artigo são apresentados 4 casos de pacientes portadores da forma cicatricial de Keith, submetidos à realização de queiloplastia pela técnica de Spina, comparados a 1 caso de paciente portador de cicatriz traumática. Todos os pacientes tiveram amostra de tecido enviada para estudo histopatológico, com coloração com hematoxilina-eosina. Os casos estudados apresentaram semelhanças entre a pele embrionária e a cicatriz comum.

Examinations of the etiology of congenital cicatricial presentations, which include congenital constriction bands and cicatricial presentations of cleft lip, have provided several theories that explain their development; however, they do not explain all the aspects involved in these malformations. In the present article, we present the cases of 4 patients with Keith's lip scar who underwent cheiloplasty using the spina technique. These cases were compared with 1 case of a patient with a traumatic scar. Tissue samples were obtained from all the patients for histopathological examination using hematoxylin-eosin staining. The cases under study exhibited similarities in embryonic skin and common scar tissue.
