Proctitis infecciosa por Streptococcus Pyogenes y Chlamydia Trachomatis - A propósito de un caso / Infectious proctitis due to Streptococcus Pyogenes and Chlamydia Trachomatis - About a case

We present the case of proctitis due to Streptococcus pyogenes and Chlamydia trachomatis, acquired by sexual transmission, in an immunocompetent patient. Sexually transmitted infections (STIs) are becoming more frequent and this possibility must be taken into account in the differential diagnosis of the causes of proctitis. The most frequent causative agents are Chlamydia trachomatis, Gonococcus, Herpes simplex virus and Treponema Pallidum, however, Streptococcus pyogenes infection should be assessed even in immunocompetent patients. It is important to consider sexually transmitted infections as a cause of proctitis to avoid a delay in antibiotic treatment and the development of complications. (AU)

Presentamos el caso de una proctitis por Streptococcus pyogenes y Chlamydia trachomatis, adquirida por transmisión sexual, en un paciente inmunocompetente. Las infecciones de transmisión sexual (ITS) son cada vez más frecuentes y se debe de tener en cuenta esta posibilidad dentro del diagnóstico diferencial de las causas de proctitis. Los agentes causales más frecuentes son Chlamydia trachomatis, Gonococo, Virus herpes simple y Treponema pallidum, sin embargo, se debe de valorar la infección por Streptococcus pyogenes incluso en pacientes inmunocompetentes. Es importante tener en cuenta las infecciones de transmisión sexual como causa de proctitis para evitar un retraso en el tratamiento antibiótico y el desarrollo de complicaciones. (AU)

Encondroma osificado en fémur. Una localización atípica. A propósito de un caso / Ossified enchondroma in femur. An atypical location. Case study

Presentamos el caso de un hombre de 61 años en el que se halló de forma incidental un encondroma a nivel proximal de fémur. Tras seguimiento, se observó la estabilidad de la lesión. El encondroma es un tumor de origen cartilaginoso benigno. Se localiza principalmente en las falanges de las manos y los pies, aunque puede observarse en húmero o fémur. Por lo general, es una lesión asintomática y se halla de manera incidental. En las radiografías suelen verse lesiones redondeadas bien definidas con radiolucidez central. Se recomienda el seguimiento con radiografías seriadas para comprobar la progresión o estabilidad de la lesión y hacer su diagnóstico diferencial con el condrosarcoma.(AU)

We report the case of a 61-year-old man in whom an enchondroma was incidentally detected at the proximal level of the femur. After follow-up the lesion was stable. Enchondroma is a benign cartilaginous tumor. It is located mainly in the phalanges of the hands and feet, although it can be seen in the humerus or femur. It is usually an asymptomatic lesion, found incidentally. On x-rays, well-defined round lesions with central radiolucency are usually observed. Follow-up with serial x-rays is recommended to verify the lesion’s course or stability and make its differential diagnosis with chondrosarcoma.(AU)

Gonalgia crónica por lipoma arborescente de rodilla. A propósito de un caso / Dor crônica no joelho devido a lipoma arborescente do joelho. Sobre um caso / Chronic knee pain due to arborescent lipoma. About a case

El lipoma arborescente es una patología poco frecuente que puede afectar a diferentes articulaciones, principalmente a la rodilla. Es importante tenerlapresente dentro del diagnóstico diferencial en casos de pacientes que presenten gonalgia crónica asociada a derrames de repetición sin traumatismoprevio asociado.(AU)

Arborescent lipoma is a rare pathology that can affect different joints, the most affected being the knee. It is important to keep it in mind in thedifferential diagnosis of patients with chronic knee pain associated with recurrent effusions without prior associated trauma that required arthroscopicsynovectomy to resolve the symptoms.(AU)

O lipoma arborescente é uma patologia rara que pode afetar diferentes articulações, sendo o joelho a mais afetada. É importante tê-lo em mente nodiagnóstico diferencial de pacientes com dor crônica no joelho associada a derrames repetidos sem trauma prévio associado que necessitaram desinovectomia artroscópica para desaparecimento dos sintomas.(AU)

Nevus de Spitz / Nevus of Spitz

El nevus de Spitz es una neoplasia de naturaleza benigna que aparece en la infancia con mayor frecuencia que en cualquier otro periodo de la vida. Algunas lesiones, especialmente aquellas localizadas en extremidades, presentan un aspecto similar al melanoma, por lo que debe establecerse el diagnóstico diferencial con esta patología. El manejo de este tipo de nevus depende de las características clínicas, así como de la edad del paciente (AU)

Spitz's nevus is a relatively frequent lesion that appears in children, it is usually a benign lesion and completely asymptomatic. Some lesions, especially those located in the extremities, have an appearance similar to melanoma, so the differential diagnosis with this pathology must be established. The management of this type of nevus depends on the clinical characteristics, as well as the age of the patient. (AU)

Granuloma aséptico facial idiopático / Idiopathic facial aseptic granuloma

Idiopathic facial aseptic granuloma (IFAG) is characterized by the appearance of a painless reddish nodule in the facial region and is exclusive to children. It is usually located on the cheek. The resolution of these lesions is usually spontaneous in months and they heal without leaving a scar or with minimal scarring. Its etiology is unknown. The diagnosis is fundamentally clinical, although sometimes complementary tests such as ultrasound can be used. This pathology presents a chronic but benign clinical course with spontaneous resolution, so in these cases a wait-and-see approach is preferred (AU)
