[Inflammatory myofibroblastic tumor of the larynx: a case report]. / Tumeur myofibroblastique inflammatoire du larynx: a propos d'un cas.

BACKGROUND: Inflammatory myofibroblatic tumor is a recently caracterized solid mesenchymal tumor. They are frequently localised in the lung. However, the head and neck forms are uncommon. AIM: To report a new case of inflammatory myofibroblastic tumor of the larynx. CASE REPORT: This 47-year old man presented with dysphonia without dyspnea. Laryngoscopy showed a tumor of anterior vocal cord. CT scan of larynx confirmed diagnosis. The patient had a cordectomy. Histology concluded to the diagnosis of inflammatory myofibroblastic tumor. No relapses have been noted after 4 months. CONCLUSION: Only a few cases of laryngeal inflammatory myofibroblastic tumor have been reported in the literature. Clinical presentation depends of tumor location. Radiological images are not specific and diagnosis is based on histology. The expected course is essentially marked by the risk of local recurrences. Surgical excision seems to be the treatment of choice.

[Squamous cell carcinoma arising in a papillary carcinoma of the thyroid: a case report]. / Coexistence d'un carcinome epidermoïde et papillaire de la thyroïde: a propos d'un cas.

BACKGROUND: primary squamous cell carcinoma (scc) of the thyroid is a rare malignant tumor that needs to be distinguished from other neoplasms. Cases of papillary carcinoma merging in association with squamous cell carcinoma are extremely rare. AIM: the characteristics of such association will be studied herein through a review of literature. CASE REPORT: we report a case of an 87-year-old patient presented with an enlarged right lobe of the thyroid. Thyroid scintigraphy revealed a cold nodule. Clinically, malignancy was suspected. Histopathologic diagnosis was a well-differentiated scc associated with areas of papillary carcinoma. Exhaustive clinical, endoscopic and radiological examinations did not reveal any primary site of scc or any contiguous spread from neighboring structures. Surgery was followed by radiotherapy, but the patient died 6 months later. CONCLUSION: the coexistence of epidermoide and papillary carcinomas in the thyroid gland must be known because of its prognostic impact.
