    ABSTRACT: The solitary fibrous tumor is an uncommon unilateral benign lesion that usually arises from the pleura. Recently, these tumors have been described in many other locations, such as the mediastinum, head and neck, orbit and urogenital system. To date, only two cases of solitary fibrous tumor arising from the larynx have been reported in the scientific literature. We describe a new case of laryngeal solitary fibrous tumor localized at the right false vocal fold. A 29-year-old man presented with a 6-month history of progressive hoarseness and foreign body sensation in the throat. A mass lesion was recognized in the right false vocal fold, and CT scan demonstrated a large, well-defined tumor without signs of infiltration. The tumor was removed by transoral CO(2) laser surgery. The definitive diagnosis was obtained by immunohistochemical analysis that showed vimentin and CD34-positive cells. The patient remains free of tumor after 15 months of follow-up.

    ABSTRACT: Ameloblastomas are the most frequent odontogenic tumours, accounting for 1% of all tumours of the maxilla and mandible. Sinonasal ameloblastomas are most common between the ages of 55 and 65, and mandibular ameloblastomas between 40 and 50. Incidence is higher in males than in females, and there are no differences between races. These locally aggressive tumours originate in the mandible in 80% of cases and in the maxilla in 15-20%. We report an unusual primary nasosinusal ameloblastoma presented in a 68-year-old male. The tumour was completely resected by (para)lateral rhinotomy and treated with postoperative radiotherapy. Histological analysis demonstrated a plexiform ameloblastoma. The patient remains well without disease after 50 months of postoperative follow-up.

    ABSTRACT: Cavernous haemangioma is a rare neoplasm that can be easily misdiagnosed as acoustic neuroma when it occurs in the internal auditory canal (IAC) or cerebello-pontine angle. A right cavernous haemangioma is reported in a 61-year-old male. The lesion was associated with non-pulsative tinnitus, deteriorating hearing loss and facial nerve dysfunction (House and Brackmann grade IV). A T1-weighted Gd-diethylenetriaminepentaacetic acid-enhanced MRI scan demonstrated a small hyperintense lesion confined to the right IAC. The tumor was completely resected via a retrosigmoidal approach. Histologic examination demonstrated a vascular tumor composed of an irregular, dilated vascular space with collagenous walls lined by a vascular endothelium. Facial nerve function remained unchanged and the patient remained well with no evidence of recurrence 2 years after surgery. We conclude that progressive hearing loss associated with facial nerve dysfunction, particularly when the lesion in the IAC is small, should raise the possibility of cavernous haemangioma.

    ABSTRACT: Cogan's syndrome is a rare autoimmune disease with systemic involvement. It appears in young people and has two presentations: the typical form with keratitis, sudden deafness with or without vestibular syndrome, and the atypical form with different non keratitic ocular diseases and a great variety of systemic symptoms in relation with the autoimmune etiology of the process. Cogan's syndrome has a bad prognosis and deafness appears in 25% of the cases with the right treatment and in 60% of patients without treatment. The best treatment is systemic and ocular corticotherapy. The second treatment of choice is cyclophosphamide or cyclosporine A. We present two cases of atypical Cogan's syndrome with unilateral deafness in both.

    ABSTRACT: Fungal sinusitis is a rare entity which has increased amongst immunocompromised individuals. Records of thirteen patients treated of fungal sinus disease between 1995 and 2001 were reviewed. Histopathological studies demonstrated infection due to Aspergillus in eight patients and due to Mucormycosis in five patients. The surgical debridement via endoscopic sinus surgery was the essential part of the management. The follow-up is 12-72 months (mean 29.08). The main clinical findings and a review of the literature are presented. We conclude that endoscopic sinus surgery is the treatment of choice for fungal sinusitis except in advanced cases of mucormycosis in which a combined approach is still necessary together with intravenous antifungal drugs (amphotericin B).
