Inverted papilloma is a rare nasosinusal tumor that mainly occurs in adults during the 5 th decade. The occurrence in children is exceptional and only few cases have been reported in the litterature. Clinical and radiological findings mimic other benign nasosinusal pathologies; therefore, diagnosis is based on histopathology either via biopsy or following surgical excision. Here we present a rare case of pediatric inverted papilloma in a 11-year-old child and we discuss clinical, radiological, therapeutic and evolutionary features through a literature review.

Castleman’s disease is a rare pathology, poorly understood. It is considered as a lymphoproliferative disorder, described for the first time in 1954, which may be confused with other causes of lymphadenopathy. We report in this paper the case of a young women presenting with left latero-cervical lymphadenopathy. All the investigations were negative except a large high-vascularized level II cervical lymphadenopathy. We performed a cervicotomy. The extemporaneous histological exam was non-contributive. We decided to perform a complete level II and III left cervical lymphadenectomy. The diagnosis of unicentric Castleman's disease was confirmed based on the final histological study of the specimen, and the absence of other cervical and extra-cervical lymphadenopathy. The patient is free of recurrence at the time of reporting this article.

Oncocytoma is a rare salivary gland tumor consisting of oncocytes with many hyperplastic mitochondria. It usually occurs in the parotid gland. Clinical diagnosis is often challenging due to the likeness of oncocytoma to other benign and low-grade malignant salivary gland tumors. We report a case of a patient who presented to our department with a right parotid swelling evolving for 1 year. Imaging studies diagnosed the lesion as a benign tumor. The patient underwent superficial parotidectomy with complete tumor excision with no complication. Definitive histology examination concludes to oncocytoma. The patient is disease free with a follow-up of 3 years.

A 43‐year‐old woman presented to the ENT department with bilateral nasal obstruction, epistaxis and bilateral exophthalmos. A diagnosis of sinonasal cancer was suggested at first; however, an ethmoïdal biopsy revealed ethmoïdal metastasis resulting from breast adenocarcinoma.
