    Notes: Abstract We describe a 12-year-old patient with a primary pulmonary mass in the left upper lung. The diagnosis of inflammatory pseudotumour was suspected preoperatively. After pathological examination and complete clinical evaluation, a diagnosis of malignant primary pulmonary fibrous histiocytoma was established. This is a very uncommon primary neoplasm of the lung and to our knoweledge only five paediatric cases have been reported. Because of the rarity of these sarcomas and histological similarities to benign inflammatory pseudotumour, care must be taken to avoid confusion between the two disorders particularly in intra-operative frozen sections. Conclusion Primary malignant fibrous histiocytoma of the lung is an uncommon tumour that should be considered in the differential diagnosis of pulmonary neoplasms of childhood. The histological diagnosis can be difficult due to the similarities with␣inflammatory pseudotumour.

    Notes: Abstract A 63-year-old man presented a polypoid tumor in the laryngeal space involving the right pyriform fossa. The patient underwent a total laryngectomy with bilateral functional neck dissection, and the diagnosis of sarcomatoid carcinoma with malignant fibrous histiocytoma-like stroma was established. The tumor showed an uncommon behavior, with distant metastases to the brain and to the subcutaneous tissue of the abdominal wall. The patient died 1 year after the development of the metastases. Despite its polypoid pattern of growth, sarcomatoid carcinoma of the larynx may behave very aggressively. It is important for clinicians to be aware of the possibility of distant subcutaneous and brain metastases in sarcomatoid tumors of the laryngeal space. If such metastases develop, the prognosis is ominous, with an average life expectancy of 3 months.
