RESUMEN
El pólipo mioglandular inflamatorio o de Nakamura es un pólipo muy infrecuente, habiendose descrito en la literatura unos 100 casos. Posee unas características tanto endoscópicas como histológicas específicas, cobrando gran importancia su conocimiento para su diagnóstico adecuado. Es de vital importancia su diagnóstico diferencial con otro tipo de pólipos tanto histológicamente como respecto a su seguimiento endoscópico. Presentamos el caso clínico de un pólipo de Nakamura como hallazgo incidental en una colonoscopia de cribado.(AU)

The inflammatory myoglandular or Nakamura polyp is a very rare polyp, with about 100 cases having been described in the literature. It has specific endoscopic and histological characteristics, making its knowledge of it very important for its proper diagnosis. Its differential diagnosis with other types of polyps is of vital importance, both histologically and with respect to its endoscopic follow-up. We present the clinical case of a Nakamura polyp as an incidental finding in a screening colonoscopy.

Ganglioneuromas are slow growing tumours arising from tissues of the neural crest, mainly in autonomic nervous system. They are frequently localized in the posterior mediastinum being the intraspinal involvement very uncommon. We present the case of a female patient with bilateral cervical ganglioneuroma, together with a review of the cases published to date, emphasizing in the main characteristics of these tumours and including them as part of neurofibromatosis type 1 spectrum.
Los ganglioneuromas son tumores de lento crecimiento que se originan en tejidos derivados de la cresta neural, principalmente en el sistema nervioso autónomo. Se localizan sobre todo en el mediastino posterior, siendo la afectación intraespinal muy poco frecuente. Presentamos el caso de una mujer intervenida de ganglioneuromas localizados en la columna cervical y agrupamos los casos descritos previamente en la literatura inglesa revisando las características principales de estas neoplasias e incluyéndolas en el espectro de manifestaciones de la neurofibromatosis tipo 1.

Infantile myofibromatosis (IM) is the most common benign fibrous tumor of infancy, characterized by the development of single or multiple nodules in the skin, soft tissues, bone, and/or viscera. Multicentric forms are less frequent and can affect different tissues simultaneously and their prognosis depends on their extension and visceral involvement. Rarely, these forms are limited to the skeleton, in which case the absence of extraosseous lesions makes it difficult to suspect this entity. We present the case of an infant with multiple radiolucent lesions involving the skull, ribs, spine, and long bones, discovered in a radiological study performed after a minor trauma. A broad differential diagnosis was considered based on the osteolytic and polyostotic nature of the lesions on imaging studies. This report details and illustrates the typical radiological findings in bony involvement of IM, which suggest this disorder over other diagnostic options.

Actinomycosis is an uncommon granulomatous infection by Gram-positive anaerobic bacteria of the genus Actinomyces. A. israelii is a major human pathogen. The most frequent locations for colonization are cervicofacial (50%), abdominal (20%) and thoracic (15-20%). The abdominal actinomycosis predisposing factors include recent surgery, trauma and neoplasias. Certain cases have been associated with the intrauterine contraception device (IUD).
