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.

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.

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.

Fungal necrotizing external otitis (NEO) is a rare disease. It is an aggressive and potentially fatal infection. The most commonly reported pathogen is Candida. We aim through this study to share our experience in the management of fungal necrotizing external otitis and discuss its diagnosis tools, anti-fungal treatment choice, and outcomes. We included fifteen patients with diagnosis criteria of fungal NEO; clinical features of NEO with positive culture swabs and/or positive serologic test to a fungal pathogen. The mean age was of 70 years with a prevalence of males. The main symptoms were otalgia (n=15) and otorrhea (n=7). Facial palsy was observed in four cases. Fungal pathogens were Candida(n=10) and Aspergillus (n=5). Complications were observed in eight cases: extension to the temporo-mandibular (n=4), abscess in the retropharyngeal space (n=2), abscess in the parapharyngeal space (n=1) and thrombophlebitis of the internal jugular vein (n=1). Six patients were treated with fluconazole, eight with voriconazole, and one patient with itraconazole. After a mean duration of 52 days of antifungal therapy, fourteen patients have been cured with normalization of the ear symptoms, biological, and imaging features. One patient died of septic shock. No recurrence of the disease was observed after a follow-up of 12 months in all cases.
