ABSTRACT
Se describe el caso clínico de un lactante de 3 meses de edad, perteneciente a la comunidad San Pablo, Estado de Portuguesa, en la República Bolivariana de Venezuela, quien fue remitido al Hospital Universitario Jesús María Casal Ramos, por presentar, posterior al nacimiento, aumento de volumen en la región cervical izquierda. Los resultados de los exámenes imagenológicos e histopatológico corroboraron el diagnóstico de linfangioma. Se realizó el proceder quirúrgico y la evolución fue satisfactoria
The case report of a 3 months infant from the San Pablo community, Portuguesa State, in the Bolivian Republic of Venezuela is described. He was referred to Jesús María Casal Ramos University Hospital due to volume increase in the left cervical region after his birth. The results of the imagenologic and histopathologic exams confirmed the diagnosis of lymphangioma. The surgical procedure was carried out and the clinical course was satisfactory

PURPOSE: To investigate the morphological aspects of the healing of traumatic wounds in rats using low-power laser. METHODS: Twenty four non isogenic, young adult male Wistar rats (Rattus norvegicus) weighing between 200 and 300g was used. The animals were randomly distributed into two groups: Control (GC) and Laser (GL), with 12 animals each. After shaving, anesthesia was performed in the dorsal region and then a surgical procedure using a scapel was carried out to make the traumatic wound. GL received five sessions of laser therapy in consecutive days using the following laser parameters: wavelength 660 nm, power 100 mW, dose 10 J/cm2. The wounds were evaluated through measurement of the area and depth of the wound (MW) and histological analysis (HA). RESULTS: When comparing the GC with the GL in MW there was a difference in area (p<0.001) and depth (p=0.003) measurement of the wounds in GL. The laser group presented more epithelization than GC (p=0.03). The other histological parameters were similar. CONCLUSION: The healing of wounds in rats was improved with the use of the laser. .

The occurrence of hepatocellular carcinoma (HCC) is closely associated with viral hepatitis or alcoholic hepatitis. Although active surveillance is ongoing in Korea, advanced or metastatic HCC is found at initial presentation in many patients. Metastatic HCC presents with a hypervascular intrahepatic tumor and extrahepatic lesions such as lung or lymph node metastases. Cases of HCC presenting as carcinoma of unknown primary have been rarely reported. The authors experienced a case of metastatic HCC in a patient who presented with a metastatic bone lesion but no primary intrahepatic tumor. This case suggests that HCC should be considered as a differential diagnosis when evaluating the primary origin of metastatic carcinoma.
