Reconstrucción del labio inferior con colgajo miomucoso del buccinador por hemangioma congénito: a propósito de un caso / Reconstruction of the lower lip with myomucosal buccinator flap due to congenital hemangioma: a case report

Los labios son repliegues músculo membranosos móviles que se encuentran en la entrada de la cavidad oral, y tienen como funcionalidad proporcionar competencia para la cavidad oral durante la masticación y el reposo. Bozzola y cols., en 1989, describieron la arteria bucal como el principal pedículo para el músculo buccinador. El objetivo de este trabajo es demostrar la efectividad del colgajo miomucoso del buccinador para reconstrucción del labio inferior en un paciente con hemangioma congénito. Este es un estudio longitudinal de tipo retrospectivo, con resultado descriptivo, que se le realizó a un paciente masculino de 32 años, para cubrimiento de defecto de lesión en labio inferior secundario a hemangioma congénito utilizando la reconstrucción con colgajo miomucoso del buccinador. El colgajo miomucoso del buccinador o colgajo yugal se considera uno de los mejores colgajos locales para la reconstrucción del labio inferior, sea cual fuere la causa, por su fácil disección y versatilidad debido a que tiene una tasa de sobrevida muy elevada con mínimas complicaciones en el posoperatorio. Nuestros resultados obtenidos concuerdan con los resultados ya publicados por diferentes autores, que llegan a las mismas conclusiones; aunque existen varias técnicas con colgajos locales para la reconstrucción del labio inferior, el colgajo del músculo buccinador o yugal se considera como una de las principales alternativas, ya que puede lograrse un labio funcional y estético.

The lips are mobile muscle membranous folds, found at the entrance of the oral cavity, whose function is to provide competition for the oral cavity during chewing and rest. Bozzola et al. in 1989, they described the buccal artery as the main pedicle for the Buccinator Muscle. The objective of this work is to demonstrate the effectiveness of the buccinator myomucosal flap for reconstruction of the lower lip in a patient with congenital hemangioma. This is a retrospective longitudinal study, with descriptive results, which was performed in a 32-year-old male patient to cover a lower lip lesion defect secondary to congenital hemangioma using buccinator myomucosal flap reconstruction. The buccinator myomucosal flap or jugal flap is considered one of the best local flaps for the reconstruction of the lower lip whatever the cause, due to its easy dissection and versatility due to the fact that it has a very high survival rate with minimal complications in the postoperative period. Our obtained results agree with the results already published by different authors, reaching the same conclusions; Although there are several techniques with local flaps for the reconstruction of the lower lip, the buccinator or jugal muscle flap is considered one of the main alternatives, since a functional and aesthetic lip can be achieved.

Tratamiento con propranolol en el síndrome de Kasabach-Merritt secundario a hemangioma hepático congénito. Caso clínico / Propranolol treatment in Kasabach-Merritt Syndrome secondary to congenital hepatic hemangioma. Clinical case

El hemangioma hepático es el tumor benigno de hígado más frecuente. Puede ser congénito o infantil, con diferentes evoluciones y complicaciones. La evolución clínica es muy variable, desde pacientes asintomáticos hasta cuadros de gravedad con insuficiencia cardíaca, síndrome de Kasabach-Merritt o síndrome compartimental. El diagnóstico se basa en la historia clínica y los estudios por imágenes, especialmente, la ecografía y el examen doppler en manos experimentadas. Resulta fundamental el diagnóstico diferencial con otras lesiones hepáticas, sobre todo, el hepatoblastoma. En los pacientes sintomáticos, el propranolol surge como primera línea terapéutica con buenos resultados y baja frecuencia de efectos adversos. Se presenta el caso de un recién nacido con hemangioma hepático asociado a síndrome de Kasabach-Merritt, con excelente respuesta y tolerancia al propranolol

Hepatic hemangioma is the most common benign liver tumor. It can be congenital or infantile with different outcomes and complications. The clinical manifestation varies from asymptomatic to severe conditions with heart failure, Kasabach-Merritt syndrome or compartment syndrome. Diagnosis depends on medical history and imaging studies, especially ultrasound and Doppler examination in experienced hands. Differential diagnosis is essential with other hepatic lesions, mainly hepatoblastoma. In symptomatic patients, propranolol emerges as the first line treatment with good results and low frequency of adverse effects. We present the case of a newborn with a hepatic hemangioma and Kasabach-Merritt syndrome with an excellent response and tolerance to propranolol.

Contrast-Enhanced Ultrasound of Congenital and Infantile Hemangiomas: Preliminary Results From a Case Series.

OBJECTIVE. The contrast-enhanced ultrasound (CEUS) imaging features of hepatic vascular tumors in infants, including infantile hemangioma (IH) and congenital hemangioma (CH), are not well reported. Frequent inaccurate use of lesion terminology in the literature has created diagnostic confusion. The purpose of this study is to describe the CEUS features of IH and CH. MATERIALS AND METHODS. Ten patients, ranging in age from 8 days to 16 months, with hepatic vascular tumors were included for retrospective analysis. Gray-scale ultrasound, color Doppler ultrasound, and CEUS features were reviewed, and interobserver kappa coefficients were calculated. Final diagnoses were clinically determined by a pediatrician with expertise in vascular anomalies except in one patient who underwent surgical excision. RESULTS. Of the 10 patients, five had CHs and five had IHs. All 10 lesions were hyperenhancing in the early arterial phase. In the portal venous phase, four of five (80%) CHs showed hyperenhancement relative to normal liver parenchyma, whereas four of five (80%) IHs showed isoenhancement. In the late phase, washout of contrast material was seen in three of five (60%) IHs, whereas one IH remained isoenhancing and one IH was hyperenhancing. None of the CHs showed late washout. Interobserver kappa coefficients for CEUS features ranged from 0.60 to 1.00. CONCLUSION. Except for the CEUS feature portal venous phase enhancement (κ = 0.60), good to excellent (κ = 0.74-1.00) agreement about CEUS features of IHs and CHs was observed. A significant proportion of IHs (60%) showed washout at delayed phase imaging, which has also been reported with malignancies. Recognition of the overlap in imaging appearance of these two entities is vital to preventing misdiagnosis of malignancy.

Tumores nasales congénitos de la linea media / Congenital nasal tumors of the midline in ENT

Las masas nasales congénitas de la línea media se presentan con una frecuencia muy baja ­1/20.000 a 1/40.000 nacidos vivos­. Se trata de hallazgos asintomáticos en el recién nacido y son resultado de anomalías congénitas del desarrollo embrionario, que suelen aparecer como masas en la línea media nasal en un punto cualquiera entre glabela y columela. Estas tumoraciones presentan un riesgo elevado de extensión al sistema nervioso central, lo que es especialmente importante tener en cuenta para prevenir consecuencias tales como la fístula de líquido cefalorraquídeo y/o la aparición de meningitis recidivante. Existen gran cantidad de tumores nasales de la línea media que aparecen en el recién nacido o en el lactante y que constituyen diagnósticos diferenciales de las lesiones congénitas antes descriptas. Describiremos brevemente los más frecuentes según nuestra experiencia. AU

Congenital nasal masses of the midline are very rare ­ 1/20,000 to 1/40,000 live births ­. Nasal tumors are asymptomatic findings in the neonate and are caused by congenital abnormalities during fetal development, usually appearing at the nasal midline between the glabella and columella. These tumors are associated with a high risk of extension to the central nervous system; therefore, it is especially important to prevent the development of a cerebrospinal fluid fistula and/or recurrent meningitis. There is a large number of nasal tumors of the midline in neonates or infants in the differential diagnosis of the above-described congenital lesion. Here we briefly describe the most common nasal tumors seen at our department. AU

Rapidly involuting congenital hemangioma

Abstract: Rapidly involuting congenital hemangioma is a rare vascular tumor that generally has a good prognosis. The authors describe a case of a newborn girl with a left cervical vascular lesion. Image exams were performed, and the lesion slowly decreased, leaving redundant skin. Considering all of the findings, a final diagnosis of a rapidly involuting congenital hemangiomas was suspected.

Congenital hemangioma in spondylocostal dysostosis: a novel association

Abstract Congenital hemangioma is a benign tumor caused by dysfunction in embryogenesis and vasculogenesis, which progresses during fetal life to manifest as fully developed at birth. Although hemangiomas are the most common tumor of infancy, rapidly involuting congenital hemangioma has not been described in spondylocostal dysostosis. I report the novel association of congenital hemangioma and spondylocostal dysostosis in a Mexican newborn female patient with neural tube defects. Given the embryological relationship between skin and nervous system, I surmise that this association is not coincidental. I also propose that these morphologic alterations be incorporated to the spondylocostal dysostosis phenotype and specifically looked for in other affected children, in order to provide appropriate medical management and genetic counseling.

Meningitis and pneumococcal pyomyositis in a child with intramuscular hemangiomas: an autopsy case report.

Pyomyositis is the bacterial infection of skeletal muscle, usually accompanied by abscesses. The main etiologic agent is Staphylococcus aureus. There are rare cases attributed to Streptococcus pneumoniae. This paper presents an autopsy of a four year old child with multiple congenital intramuscular hemangiomas that developed pneumococcal pyomyositis associated with meningitis. The authors propose the hypothesis that patients with hemangiomas, mainly the intramuscular type, may also represent a risk group for pyomyositis. The possibility of respiratory/meningeal co-infection, might also be considered even if the clinical picture is restricted to the muscular system.

Hemangiomas congénitos rápidamente involutivos: serie de 25 casos / Rapidly involuting congenital hemangiomas: twenty five case series

Los hemangiomas congénitos rápidamente involutivos son tumores vasculares muy poco frecuentes, que se caracterizan por estar completamente desarrollados al nacer (congénitos) y por tener una involución espontánea en un corto período (rápidamente involutivos). Describimos una serie de 25 casos de hemangiomas congénitos rápidamente involutivos, de los cuales 12 eran del sexo masculino y 13, femenino. Todos los pacientes eran nacidos a término, con peso adecuado para la edad gestacional. En 17, las lesiones fueron de pequeño tamaño y, en 8, de gran tamaño. Ningún paciente requirió tratamiento. En todos ellos, las lesiones mostraron una rápida involución inicial.

Rapidly involuting congenital hemangiomas are very rare vascular tumours, that are characterized for being completely developed at birth and for involuting in a short period of time after birth. We describe a case series of 25 patients with rapidly involuting congenital hemangiomas. Twelve patients were male and 13 female; they were all born at term. Lesions were small in 17 cases and big in 8. No patient needed active intervention and all lesions showed a rapid initial involution.
