Hemangioma microvenular: lesión vascular benigna de patrón infiltrante. Presentación de 3 casos y revisión de la literatura / Microvenular hemangioma: a benign vascular lesion with an infiltrating pattern. Report of three new cases and review of the literature

El hemangioma microvenular es una tumoración vascular benigna poco frecuente, adquirida y autolimitada. Se presenta con mayor frecuencia como una placa o pápula única, eritematoviolácea en tronco o extremidades de adultos jóvenes con predilección por el sexo femenino. Histológicamente se caracteriza por presentar una proliferación de vasos pequeños e irregulares en la dermis con un patrón infiltrante y endotelios sin atipia. El estudio inmunohistoquímico demuestra positividad con marcadores vasculares. La morfología junto con las características clínicas orientan su diagnóstico y permiten excluir un sarcoma de bajo grado u otras lesiones vasculares benignas. Nosotros presentamos 3 nuevos casos y revisión de la literatura (AU)

Microvenular hemangioma is an uncommon, benign, acquired vascular tumour which usually occurs as a solitary purple to red plaque o papule in the extremities and trunk of young adults, more frequently in women. Histologically, these tumours are characterized by a proliferation of small blood vessels throughout the dermis, with an infiltrative growth but without endothelial atypia. Immunohistochemistry shows positivity for vascular markers. Histopathology and clinical features are required to confirm the diagnosis and to exclude well differentiated sarcomas and other benign vascular lesions. We report three new cases and review the literatura (AU)

[Adenomatoid tumors of the epididymis and testicle: report of 9 cases and bibliographic review]. / Tumor adenomatoide de epidídimo intratesticular: A proposito de nueve casos y revisión de la literatura.

BACKGROUND: To report the cases of adenomatoid tumors seen at Hospital Universitario La Paz in the last 15 years. METHODS: A clinical, pathological, and surgical study was conducted of males with testicular or paratesticular tumors with a histological report of adenomatoid tumor. RESULTS: Among the nine cases studied, seven had paratesticular and two intratesticular adenomatoid tumors. Treatment of choice was mass removal for epididymal tumors and orchidectomy for intratesticular tumors. CONCLUSIONS: Adenomatoid tumors are uncommon benign neoplasms of a possible mesothelial origin. Because of their benign nature, the treatment of choice is local excision (conservative surgery), but orchidectomy was performed in two cases due to tumor location.

OBJETIVO: Describir los casos de tumores adenomatoides del Hospital Universitario La Paz en los últimos 15 años.MÉTODOS: Se ha realizado estudio clínico, anatomopatológico y quirúrgico de los varones con tumoración testicular o paratesticular con resultado histológico de tumor adenomatoide.RESULTADOS: En total hay nueve casos; siete presentaron tumor adenomatoide de localización paratesticular y dos intratesticular. La exéresis de la masa fue el tratamiento de elección en los epididimarios y orquiectomía en los intratesticulares.CONCLUSIONES: Los tumores adenomatoides son neoplasias benignas, poco frecuentes, de posible origen mesotelial. Como consecuencia de su naturaleza benigna, el tratamiento de elección es la exéresis local (cirugía conservadora), aunque en dos casos se llevó a cabo orquiectomía debido a su localización(AU)
