Nasal Lobular Capillary Hemangioma During Pregnancy: A Systematic Review.

Objective: To perform a systematic review of published cases of nasal lobular capillary hemangioma (LCH) during pregnancy. Data Source: PubMed, Embase, Scopus, Web of Science, and LILACS. Review Methods: We searched electronic databases from inception to June 30, 2022. Case report and case series that reported clinical data on nasal LCH during pregnancy were included. Categorical variables were expressed as proportions and numerical variables as mean ± standard deviation or median (interquartile range). Results: Twenty-three studies (20 case reports and 3 case series) involving 29 patients were included. The mean age was 30.5 ± 5.3 years. A total of 62% cases were diagnosed in the third trimester of pregnancy. The most frequent (62%) location of LCH was the nasal septum. All cases presented with epistaxis. A total of 48% cases were treated by surgical excision after delivery and the recurrence was 11%. Conclusion: Our review shows that nasal LCH during pregnancy usually manifests in the third trimester. This lesion can be treated by surgical excision with a relatively low risk of recurrence.

Diagnosis and management of exuberant palatal pyogenic granuloma in a systemically compromised patient - Case report.

AIM: To discuss the diagnosis and treatment of an exuberant oral pyogenic granuloma (OPG) in the palatal region in a systemically compromised patient. METHODS AND RESULTS: A 50-year-old woman presented with extensive and painless nodular mass that extended throughout the palatal region, with difficulty speaking, swallowing and spontaneous bleeding for 6 months. Her medical history showed poorly controlled type II diabetes mellitus and hypertension. The intraoral physical examination also revealed poor oral hygiene and periodontal disease. After clinical and radiographic evaluation, the presumptive diagnosis of OPG was made and complete excision of the lesion was performed. Local hemostatic measures were employed to control bleeding. Microscopic evaluation showed a lobulated lesion composed of many blood capillaries confirming the diagnostic hypothesis. CONCLUSIONS: In summary, individuals with severe periodontal disease and systemic disorders may present exacerbated clinical presentations of OPG.

Angioleiomioma oral mimetizando um granuloma piogênico: relato de caso raro / Oral Angioleiomyoma mimetizing a pyogenic granuloma: A rare case report

Angioleiomioma (AL) é um tumor benigno de origem perivascular que raramente é observado na cavidade oral, principalmente em localizações como a gengiva. Devido sua apresentação clínica inespecífica, os ALs podem mimetizar outras lesões orais, como tumores benignos de glândulas salivares e lesões reacionais, como o granuloma piogênico. O presente artigo objetiva relatar um caso raro de AL localizado em gengiva, em uma paciente de 19 anos. Clinicamente, a lesão apresentava-se como um tumor assintomático, oval, pedunculado, bem definido, com superfície lisa, consistência fibrosa e cor eritematosa, semelhante a um granuloma piogênico, Uma biópsia excisional foi realizada e o fragmento foi encaminhado para análise histopatológica, que revelou uma proliferação vascular de diversos calibres, contendo paredes musculares espessas e proliferação muscular adjacente, além de infiltrado inflamatório, predominantemente crônico, hemácias extravasadas e área de ulceração, consistente com o diagnóstico de AL inflamado. A histopatologia desempenha um papel importante no diagnóstico final de lesões raras e com características clínicas inespecíficas. A excisão cirúrgica da lesão é o tratamento de escolha mais eficaz para os ALs orais. (AU)

Angioleiomyoma (AL) is a benign tumor of smooth muscle of perivascular origin that is rarely seen in the oral cavity, mainly in locations like the gingiva. Due to their nonspecific clinical presentation, ALs can mimic other oral lesions, such as benign salivary gland tumors and reactional lesions, as a pyogenic granuloma. We reported a case of an AL located in the gingiva in a 19-year-old female patient. In clinical terms, the lesion was presented as an asymptomatic, oval, pedunculated, well-defined nodule with a smooth surface, fibrous consistency and erythematous color, similar to a pyogenic granuloma. An excisional biopsy was performed and the fragment was sent for histopathological analysis that revealed a vascular proliferation of different calibers, containing thick muscle walls and adjacent muscle proliferation, in addition to an inflammatory infiltrate, predominantly chronic, extravasated red blood cells and an area of ulceration, consistent with the diagnosis of inflamed AL. The histopathology plays an important role in the final diagnosis of rare lesions and with nonspecific clinical characteristics. The surgical excision of the lesion is the most effective treatment of choice for oral ALs. (AU)

Granuloma piogénico oral de comportamiento agresivo: Reporte de un caso / Oral pyogenic granuloma with aggressive behavior: A case report

El granuloma piogénico es una lesión vascular reactiva benigna del tejido blando que surge en respuesta a irritantes crónicos de bajo grado. Rara vez crece más de 2 cm de diámetro y por lo general, no provoca cambios en el hueso alveolar. Presentamos un caso inusual de granuloma piógeno en una mujer de 19 años, de extenso tamaño y comportamiento agresivo, asociado a resorción ósea severa, movilidad dentaria, hemorragia, anemia ferropénica y recurrencias.

Pyogenic granuloma is a benign reactive vascular lesion of the soft tissue that arises in response to chronic low-grade irritants. It rarely grows more than 2 cm in diameter and usually does not cause changes in the alveolar bone. We present the case of a 19-year-old woman with an unusual pyogenic granuloma of extensive size and aggressive behavior, associated with severe bone resorption, tooth mobility, hemorrhage, iron deficiency anemia and recurrences.

Unusual clinical presentation of oral pyogenic granuloma with severe alveolar bone loss: A case report and review of literature.

BACKGROUND: Pyogenic granuloma (PG) is a localized, reddish and vascularized hyperplastic lesion of the connective tissue which occurs in the oral cavity. In most cases, the presence of this lesion does not show alveolar bone resorption. The pathology is diagnosed clinically with some caution. However, the diagnosis and treatment are usually corroborated with histopathological evidence. CASE SUMMARY: Three clinical cases of PG associated with bone loss were described in this study. The three patients presented tumor-like growth which bled on touch, and were associated with local irritant factors. Radiographs showed bone loss. All cases were treated with conservative surgical excision. The scarring was satisfactory, and there was no case of recurrence. The diagnoses were based on clinical findings, and were confirmed histopathologically. CONCLUSION: The occurrence of oral PG with bone loss is unusual. Therefore, clinical and radiographic evaluations are important for the diagnosis.

Hemangioma lobular capilar inusual en un paciente pediátrico. Reporte de caso y revisión de literatura / Unusual capillary lobular hemangioma in a pediatric patient. Case report and literature review

Lobular capillary hemangioma or pyogenic granuloma is a benign non-neoplastic lesion that is mainly presented as a tissue growth in response to irritation or trauma. It is located on the skin or on the mucous membrane, with the oral mucosa being the most frequent, with the gingiva standing out, but also appearing in other places such as the lips, buccal mucosa, palate and tongue, the latter being a very unusual location. This is a report of the case of a pediatric patient who underwent a surgical procedure of frenotomy, and who subsequently presented a lesion due to trauma possibly as a consequence of local anes-thesia, which forced an excisional biopsy, the histopathological diagnosis being capillary lobular hemangioma or pyogenic granuloma. Likewise, a literature review of this type of pathology is presented, with emphasis on its location in the tongue.

Intravascular lobular capillary hemangioma of the temporal artery.

Lobular capillary hemangiomas (LCHs) are a common form of benign vascular tumors originating from the skin and subcutaneous tissues. We have described the case of a 47-year-old man who had presented with a 1-month history of a tender swelling to the right temporal region. Biopsy was performed to rule out temporal arteritis and demonstrated a subset of LCH, now formally known as intravascular LCH. We have described the occurrence of a rare subtype of LCH arising from the intravascular wall of the temporal artery. To the best of our knowledge, this is the only reported case of an intravascular LCH in the Caribbean.

Granuloma piógeno por picadura de insecto

RESUMEN Introducción: El hemangioma lobular capilar es un tumor de tejidos blandos relativamente frecuente. Se conoce que es un desarrollo reactivo focal de tejido fibrovascular o de granulación con proliferación endotelial, que no tiene relación con ninguna bacteria. Se desarrolla rápidamente, sangra con facilidad y se ulcera causando la impresión clínica errónea de un tumor maligno. Objetivo: Contribuir al conocimiento de esta afección para su detección precoz y tratamiento oportuno. Presentación de caso: Paciente masculino, de 6 años de edad, con antecedentes de buena salud, que es traído a consulta porque su madre refiere que desde hace más de un mes, comenzó con una pequeña lesión en la cara después de la picadura de un insecto que creció y sangra con facilidad de manera espontánea o después de algún traumatismo. Al examen dermatológico se constata cuadro cutáneo localizado constituido por lesión única en forma de tumor, de aproximadamente 0,5 cm, de color rojo intenso, que sangra con facilidad con el mínimo roce localizada en la cara. Se trató con criocirugía y se logró eliminación de la lesión casi sin cicatriz aparente. Conclusiones: La extirpación quirúrgica completa se considera el tratamiento de primera línea porque se evitan las recidivas y, al mismo tiempo, puede obtenerse material suficiente para el estudio histopatológico. En los casos con diagnóstico de certeza es útil el uso de criocirugía y electrofulguración para impedir las alteraciones estéticas provocadas por la cirugía.

ABSTRACT Introduction: Capillary lobe hemangioma is a relatively common soft tissue tumor. It is known to be a focal reactive development of fibrovascular or granulation tissue with endothelial proliferation, which is not related to any bacteria. It develops rapidly, bleeds easily and ulcerates causing the clinical erroneous impression of a malignant tumor. Objective: Contribute to the knowledge of this condition for its early detection and timely treatment. Case presentation: Male patient, 6 years old, with a health history, who is brought to consultation because his mother reports that for more than a month he presented a small lesion on the face after the bite of an insect that grew and bleeds easily, spontaneously or after some trauma. The dermatological examination shows a localized skin condition consisting of a single lesion in the form of a tumor, approximately 0.5 cm, of intense red color, which bleeds easily with the minimum friction, and it was located on the face. It was treated with cryosurgery and the removal of the lesion was achieved with almost no apparent scar. Conclusions: Complete surgical removal is considered the first-line treatment because recurrences are avoided and, at the same time, sufficient material can be obtained for histopathological study. In cases with a diagnosis of certainty, the use of cryosurgery and electrofulguration is useful to prevent the aesthetic alterations caused by surgery.

Granuloma piógeno en el dorso lingual: caso clínico / Pyogenic granuloma in the lingual dorsum: a clinical case

El granuloma piógeno es una lesión benigna en la cavidad bucal, no neoplásica. Es una entidad fre- cuentemente asociada a la expansión de los tejidos blandos de la cavidad bucal. Se presenta, con mayor frecuencia, en individuos del género femenino, con edades comprendidas entre la segunda y cuarta década de vida. El tratamiento es mediante escisión quirúrgica con un pequeño margen de seguridad, y los agentes irritantes deben extraerse concomitan- temente para la curación de la lesión. Este trabajo tuvo como objetivo informar un caso de granuloma piógeno en el dorso de la lengua en una paciente del género femenino de 69 años. Los autores destacaron la importancia del conocimiento de la patología bucal por parte del Cirujano Dentista para poder realizar un correcto diagnóstico diferencial de otras lesiones, con el fin de realizar el tratamiento adecuado (AU)

Pyogenic granuloma is a quite common non-neoplasic benign lesion in the oral cavity. It is one of the entities most frequently associated with the soft tissues' expansion of the oral cavity, specifically in females, in the age group between the second and the fourth decade of life. The treatment is by surgical excision with a small margin of safety. For the healing of the lesion irritants should be concomitantly removed. This study aimed to report a case of pyogenic granuloma on the lingual dorsum of a 69-year-old female patient. The authors concluded highlighting the importance of the knowledge of oral pathology by the Dental Surgeon, to perform a correct differential diagnosis of other lesions to perform the appropriate treatment (AU)

Granuloma piógeno oral. Serie de casos / Oral pyogenic granuloma. Case series

RESUMEN El granuloma piógeno es una lesión que se manifiesta en la piel y en la cavidad oral, relacionado con diversas causas, como irritación crónica, trauma y cambios hormonales. Clínicamente se muestra como una lesión hiperplásica altamente vascularizada, con un tamaño de 1-3 cm, de base pedunculada o sésil y de crecimiento lento. Predomina en el sexo femenino y tiende a aparecer, sobre todo, en la encía, con muy pocos casos reportados en zonas edentes, motivo por el que se realizó el reporte de tres casos de granuloma piógeno oral en pacientes femeninas, comprendidas entre 30 y 40 años de edad. Se presentaron lesiones que diferían en cuanto a su localización y apariencia clínica (AU).

ABSTRACT Pyogenic granuloma is a lesion that arises in the skin and oral cavity, related to various causes, such as chronic irritation, trauma and hormonal changes. Clinically it looks like a highly vascularized hyperplastic lesion, sized 1-3 cm, with a pedunculated or sessile base and slow growing. It predominates in the female sex and tends to appear, above all, in the gum, with very few cases reported in edentulous areas; that is why the authors reported three cases of oral pyogenic granuloma in female patients, aged between 30 and 40 years. The lesions differed in their location and clinical appearance (AU).

Plump endothelial cells integrated into pre-existing venules contribute to the formation of 'mother' and 'daughter' vessels in pyogenic granuloma: possible role of galectin-1, -3 and -8.

INTRODUCTION: Pyogenic granuloma (PG) is a reactive inflammatory vascular lesion of the skin and mucous membranes, characterised by the presence of enlarged venules and seamed and seamless capillaries with plump endothelial cells (EC), and numerous macrophages. EC activation upregulates the synthesis of galectins and induces their translocation to the EC surface promoting angiogenesis and lymphangiogenesis, particularly galectin-1 (Gal-1), Gal-3 and Gal-8. However, the presence and distribution of Gal-1, -3 and -8, as well as their implications in the pathogenesis of PG, has not been considered. MATERIALS AND METHODS: Eight biopsies from patients diagnosed with PG were selected. The presence of PECAM-1/CD31, IL-1ß, VEGF-C, VEGFR-2, VEGFR-3, integrin ß1, CD44, fibronectin and Gal-1, -3 and -8 was assessed by immunofluorescence staining using confocal laser scanning microscopy. RESULTS AND DISCUSSION: Immunostaining revealed that these molecules were present in the enlarged venules with plump ECs, in some macrophages and other immune cells. We propose that macrophages release VEGF-A and VEGF-C inducing VEGFR-2/VEGFR-3 expression and activation, leading macrophages to transdifferentiate into plump ECs that might integrate into pre-existing venules, contributing to the formation of enlarged venules with transluminal bridges and capillaries. EC activation, induced by certain cytokines, has been shown to stimulate galectin expression and changes in the cellular localisation through association and activation of specific EC surface glycoproteins. Therefore, it is plausible that Gal-1, -3 and -8, acting in a concerted manner, could be mediating the transdifferentiation of macrophages into plump ECs and facilitating their migration and incorporation into the new vessels. LAY SUMMARY: In this study, immunostaining of pyogenic granuloma (PG) tissue sections showed immunoreactivity for PECAM-1/CD31, IL-1ß, VEGF-C, VEGFR-2 and VEGFR-3, and galectin-1, -3 and -8 in enlarged venules with plump endothelial cells (EC), as well as in some macrophages and other immune cells. Interestingly, enlarged and thin-walled transient vessels lined by PECAM-1/CD31 and VEGFR-2 immunopositive ECs that form from pre-existing normal venules in response to VEGF-A (called 'mother' vessels [MV]) and that undergo intraluminal bridging evolving into various types of capillaries (called 'daughter' vessels [DV]) have been observed in benign and malignant tumours, in physiological and pathological angiogenesis as well as in vascular malformations, suggesting an important role for VEGF-A and VEGFR-2 in such a process. However, it is not only the mechanisms by which the MVs evolve in different types of DVs that remains to be elucidated, but also whether the cells that form intraluminal bridges proceed from locally activated ECs or whether they are derived from bone marrow precursors or from resident macrophages.Given that the formation of homodimers by Gal-1 and Gal-8 and pentamers by Gal-3 to generate gal-glycan lattices at the cell surface and in the extracellular space has been shown, it is possible that in PG tissue Gal-1, -3 and -8, through their binding partners, form a supramolecular structure at the surface of ECs and plump ECs, macrophages and in the extracellular space that might be mediating the transdifferentiation of macrophages into plump ECs and facilitating the migration and incorporation of these cells into the pre-existing venules, thus contributing to the formation of MVs and DVs.

Abstract Oral pyogenic granuloma is a benign multifactorial lesion that appears as a highly vascular gingival enlargement. It can be located anywhere in the oral cavity, most often in the vestibular marginal gingiva. It occurs most frequently in adult women and male children. It does not usually compromise bone tissue or teeth; its safest treatment is surgical excision, with a high recurrence risk. This study aims to report the case of a 9-year-old female patient who underwent oral pyogenic granuloma excision in the maxilla. The following year, she presented a possible lesion recurrence with alveolar bone loss and the mobility of an adjacent tooth. A biopsy and thorough curettage were performed, confirming the diagnosis of oral pyogenic granuloma.

Un inusual caso de granuloma piogeno oral multiple, ¿asociado a tratamiento con levotiroxina? / An unusual case of multiple oral pyogenic granuloma, ¿associated with treatment with levothyroxin?

RESUMEN El Granuloma piógeno (GP) es una lesión tumoral, no neoplásica, vascular, generalmente solitaria, que se presenta en la cavidad oral o piel, la etiología aún no está muy clara, se considera que es una lesión reactiva a varios estímulos de bajo grado, entre los cuales podemos contar traumas repetidos, agresiones, factores hormonales y ciertos fármacos. El GP múltiple, es un fenómeno raro, generalmente asociado al uso de drogas, como la carbamacepina, ciclosporina, retinoides, levotiroxina, etc. Se presenta el caso de una paciente de 50 años, referida por presentar aumento de volumen en reborde alveolar del primer, tercer y cuarto cuadrantes; con antecedentes de psoriasis eritrodermica e hipotiroidismo, en tratamiento con levotiroxina aproximadamente seis meses antes que se presenten las lesiones; se realiza exeresis quirúrgica y curetaje subperiostico, se enviaron las muestras a anatomía patológica, confirmándose el diagnóstico definitivo de GP; por los antecedentes, y la aparición casi simultánea de las lesiones en múltiples cuadrantes, se sospecha que estas, están asociadas al consumo terapéutico de levotiroxina para el hipotiroidismo.

SUMMARY Pyogenic Granuloma (GP) is a tumorous, non-neoplastic, vascular, generally solitary lesion that presents itself in the oral cavity or skin, the etiology is still not very clear, it is considered to be a reactive lesion to several low grade stimuli, among which we can count repeated trauma, aggressions, hormonal factors and certain drugs. The multiple GP, is a rare phenomenon, generally associated with the use of drugs, such as carbamacepine, cyclosporine, retinoids, levothyroxine, etc. It presents the case of a patient of 50 years, referred for presenting increased volume in alveolar ridge of the first, third and fourth quadrants, with a history of erythrodermic psoriasis and hypothyroidism, in treatment with levothyroxine approximately six months before the lesions occur; Surgical exeresis and subperiosteal curettage is performed, samples were sent to pathological anatomy, confirming the definitive diagnosis of GP; because of the history, and the almost simultaneous appearance of the lesions in multiple quadrants, it is suspected that these are associated with the therapeutic consumption of levothyroxine for hypothyroidism.
