[Localised bronchi amyloidosis: a case report].

Localised pulmonary amyloïdosis is exceptional. Tracheobronchial symptoms are the most frequent. We report a case of a 68 year-old man complaining of cough and breathlessness. Bronchoscopy showed a submucosal infiltration with stenosis of left upper and lower bronchi. Multiples biopsy were performed and concluded to amyloïdosis of AL type. Our objective is to describe the anatomopathologic aspects of localised pulmonary amyloïdosis and to discuss its pathogeny.

[Epithelioid bilateral ovarian leiomyosarcoma: a study].

Primary ovarian leiomyosarcoma is extremely rare and generally affects post menopausal women. It is usually unilateral and more than 10 cm in diameter. Its histogenesis is not clear its prognosis seems to be improved by radical surgery and adjuvant therapy. We report a case of a 54 year-old, nulliparous, post menopausal woman who had abdominal distention. Physical examination revealed a large pelvi-abdominal mass. The excision of tumor with bilateral salpingo-oophorectomy and hysterectomy was carried out. A diagnosis of bilateral ovarian epithelioid leiomyosarcoma was made on pathological examination with immunohistochemistry. Adjuvant chemotherapy was given. After 3 months of follow up, abdominal sonography revealed a peritoneal recurrent tumor with hepatic metastasis. Our objectives are to discuss the histopathological features and the prognosis of this tumor.

[Pulmonary oxalosis with necrotizing pulmonary aspergillosis].

Pulmonary oxalosis is a very rare pseudotumoral lesion; it is often secondary to an aspergillus infection. Oxalic acid (C(2)H(2)O(4)) is a mycotoxin released by Aspergillus niger and sometimes by several other fungi, including A flavus and A fumigatus. We report a case of a 69 year old man, with previous history of pulmonary tuberculosis, followed for recurrent hemoptysis. On the chest radiography, the right upper lobe lung showed a cavitary lesion with thick and irregular walls and a dense material that suggested a pulmonary aspergilloma. Microscopically, it was a pulmonary oxalosis associated with chronic necrotising pulmonary aspergillosis. Our aim is to discuss the epidemiological characteristics, the diagnosis and the histogenesis of this unusual lesion.
