Multicentric recurrent parotid pleomorphic adenoma in a child.

Mixed tumours of the parotid gland are rare in childhood and recurrence of this tumour is infrequent. Some authors report a higher rate of recurrence with some histological subtypes, like hypocellular variant. Female sex and young age at initial treatment are also risk factor for recurrence.

Wegener's granulomatosis: description of a case with oral manifestation.

Wegener's granulomatosis is a multisystemic granulomatous vasculitis that predominantly affects the airways and the kidneys, but may affect any organ. Otorhinolaryngological manifestations may be oral ulcers, gingival swelling or septal perforations that can cause saddle nose deformities, rhinitis, sinusitis and hearing loss. The oral ulcers usually occur when the disease is advanced.

[Solitary extramedullary plasmocytoma of tubaric tonsil].

Several histopathological modalities of tumours can grow in the rhinopharynx. Solitary extramedullary plasmocytoma (SEP) is a low frequent variety of low-grade lymphoma. The aim of this work is to present a new case of SEP localized in rhinopharynx and to perform a review of diagnostic and therapeutic protocols of these neoplasias.

[Chondromyxoid fibroma of the left maxillary and ethmoid sinuses].

Chondromyxoid fibroma is an infrequent bone tumour in the craniofacial bones and exceptional in the paranasal sinuses. This unusual location, its non-specific clinical manifestation and aggressive behaviour with local destruction and a high recurrence rate can complicate precise diagnosis and treatment.
