[Foreign body ingestion in children: our experience and review of the literature]. / La ingestione di corpi estranei in eta' pediatrica: nostra esperienza e revisione della letteratura.

Foreign body ingestion is a frequent event in paediatric population, especially in the first six years of life. Even if the event is normally cause of anxiety for the parents witness of the situation, fortunately most ingested foreign bodies ingestion, about 80-90%, pass spontaneously, 10-20% of cases needs an endoscopic intervention and only in less than 1% of cases surgery is necessary. Many authors suggest different guide-lines for diagnosis and therapy of foreign body ingestion in children. These purposes are discordant not only on potential danger of foreign body, but also on timing and last of waiting period before endoscopic extraction. Here we report our own experience: a retrospective review of three hundred consecutive paediatric cases of foreign body ingestion between June 2001 and February 2008. This study don't take in account patients with pathology either organic either functional, that can cause stop of food progression. We describe and discuss about medical diagnostic and therapeutic procedures that have been done during the time of hospitalization and performed according to classic and new international literature, with the objective to propose recommendations helpful for a correct management of children presenting with a history of suspected ingestion of a foreign body.

Hamartomatous angiolipoma of the parotid gland (sialoangiolipoma).

Mesenchymal tumors of the salivary glands are rare and mostly localized to the parotid gland. We report on the clinico-pathological features of a distinct parotid tumor occurred in a newborn, showing glandular structures admixed with mature lipocytes and blood vessels in variable proportions. This was a well-circumscribed and slowly growing nodule of the superficial parotid lobe, mostly reddish in color with white-yellowish striations. Microscopically, a distinct lobular architecture was evident, along with normal-appearing acinar and ductal structures with interposed loose fibrous stroma. The latter contained aggregates of mature lipocytes and variably sized blood vessels. The morphological features of the lesion reported herein recapitulate those of sialolipoma but also include the presence of a prominent vascular component intimately admixed with both the glandular and the adipose tissues. At variance with salivary lipoadenoma, the glandular component in the current case distinctly showed all the cellular components of normal salivary (serous) glands. In consideration of the young age of the patient, the minimal growth rate and the histological features of the lesion, we hypothesize a hamartomatous origin for this lesion and propose the designation of sialoangiolipoma.
