Globally, the characteristics of this series are closely correlated with those reported in the literature. Due to the non-specific laryngeal signs observed on clinical examination, clinicians must consider the possibility of laryngeal tuberculosis and must not hesitate to confirm this diagnosis by bacteriological and histological examination

Rhinolithiasis is a rare condition often neglected or unknown that tends to disappear in developed countries and corresponds to a solid calcification by gradual deposition of calcareous salts around a central resorbable or non-resorbable foundation of varying shape and size. The most common symptom is a long-term unilateral purulent rhinorrhea and unilateral nasal obstruction. Nasal endoscopy and imaging are interesting for the positive diagnosis but especially to highlight the anatomical anomalies or related pathologies. Therapeutic management requires endonasal extraction of the rhinolith under general anesthesia. We report an observation of rhinolithiasis treated in our department associating a significant deformation of the nasal pyramid to osteolysis.

Carcinoma arising in pleomorphic adenoma is a rare entity. A case of mucoepidermoid carcinoma in pleomorphic adenoma occurring in the soft palate of a 40-year-old woman is reported. An intraoral excision of the tumor was performed. Histopathological examination revealed high-grade mucoepidermoid carcinoma proliferated in pleomorphic adenoma with free surgical margin. The patient received adjuvant neck radiotherapy. She remains free of disease 16 months post-treatment.

Only histological examination with immunohistochemistry is able to confirm the diagnosis (factor VIII, CD34 and CD31 antigens). Standard treatment consists of surgery with wide resection followed by radiotherapy. The authors discuss the treatment modalities and prognosis of this tumour.
