Highlights Sialolipoma is a rare salivary gland tumor defined histologically by mature adipocytes encasing normal salivary glandular components. Complete excision of the mass with the lobes of the salivary glands involved seems to be adequate for definitive management. Congenital sialolipoma should be kept in mind in the differential diagnosis of congenital parotid mass, especially when CT scanning shows a well‑circumscribed fat‑like tissue within the parotid gland. Although surgical excision is usually sufficient to treat sialolipoma of the parotid gland, postoperative follow-up is necessary as multifocal lesions can potentially persist, which could lead to recurrence.

Introduction Lipoblastoma is a rare benign tumor arising from embryonic white fat which occurs in the early childhood. It usually arises on the extremities and considered as a rare cause of a pediatric head and neck masses. The aim of this study is to shed light on lipoblastomas as a differential diagnosis of rapidly growing soft fatty masses of children in neck and head area. Patients and methods A retrospective review of 3 patients with lipoblastoma, underwent Surgical resection (case 1 and 2) by cervical approach. The third patient with a facial lipoblastoma was not operated due to the high risk of facial paralysis. Review of literature, diagnostic methods and genetics of lipomatous tumors are discussed. Results Complete surgical excision via a cervical approach demonstrated irregular lobules of immature fat cells separated by a loose, myxoid connective tissue. Histology analysis confirmed the diagnosis of lipoblastoma. Discussion Lipoblastoma is a rare childhood tumor, even rarer in head and neck area. The pathogenesis is unknown, though it is believed to arise from altered embryogenesis of human white fat and genetic predisposition, as chromosome 8 abnormalities may be implicated in the development of lipoblastoma. The presumptive diagnosis is performed by imaging. The most important differential diagnosis of lipoblastoma is myxoid liposarcoma. The mainstay of treatment is complete non-mutilating resection of the tumor to avoid recurrence. Conclusion Lipoblastoma should be suspected in case of heterogeneous fatty tumor in head and neck area, and included as a differential diagnosis of cervical masses in children younger than 3 years. The mainstay of treatment is complete surgical excision with a good prognosis.

Esophageal perforation following an impacted foreign body (FB) is a rare and potentially life-threatening condition. Early clinical suspicion and imaging are important for a targeted management to achieve a good outcome. Endoscopic extraction of esophageal FB is a good and safe treatment alternative while the surgical procedure remains a necessary option for many patients. We present the case of a 50 years old woman, with no relevant medical history, who accidently ingested a chicken bone during a meal causing mild dysphagia. The patient consulted immediately but was reassured after normal clinical examination. We received the patient 9 days later with severe dysphagia and cervicomediastinal cellulitis. The cervical CT scan showed the significant collection and the FB impacted in the cervical esophagus wall. A first endoscopic exploration drained the pus and allowed the placement of a nasogastric tube. However, the removal of the FB required an open cervical surgery with the evacuation of the collection and the suture of the esophageal perforation followed by the placement of a drainage tube. The patient medical state improved rapidly and no further incidents were noted. The diagnosis of esophageal FB should be meticulous in order to avoid such life-threatening complications.
