[Pulmonary hyalinizing granuloma: review of two cases]. / Le granulome pulmonaire hyalinisant: à propos de deux cas.

Pulmonary hyalinizing granuloma is a rare fibrosing nodular disease of the lung characterized by solitary or multiples pulmonary nodules. This report describes two cases of this rare disorder. MRI was available in one case. For the first case, the stability of the lesions and past history of retroperitoneal fibrosis suggested the diagnosis. For the second case, open lung biopsy was required for diagnosis. When multiple nodules are present, metastatic disease cannot be excluded and biopsy may be required. Evolution is usually benign but follow up is necessary.

[Radiological and clinical aspects of bronchogenic lung cysts: 4 case reports]. / Aspects radio-cliniques des kystes bronchogéniques pulmonaires. A propos de 4 cas.

Bronchogenic lung cysts are exceptional. We report four cases which raised a problem of differential diagnosis. Our patients included four women and a young boy (age range 12 - 36 years). The first patient consulted for bloody purulent sputum in a context of an infectious syndrome. The second patient had lower right-sided chest pain. The cyst was a fortuitous discovery in the other two cases. In one case, the chest x-ray disclosed a thin-walled cavity of the upper right lobe, confirmed on the CT scan which also evidenced intracavitary partitions. In two other cases, the chest x-ray showed a liquid-filled opacity (one in the lower right lobe and the other in the upper right lobe) and no further specificity on the CT scan. In the last case, a liquid-air cavity was evidenced. Upper right lobectomy was performed for the case with an air-filled cavity and tumorectomy for the other cases. Pathology reported bronchogenic cyst in all cases. The radiological and clinical presentations observed in patients with bronchogenic lung cysts, with or without tracheobronchial communication, are polymorphous, often raising problems of differential diagnosis.

[Bronchoesophageal fistula with late revelation]. / A propos d'une fistule broncho-oesophagienne de révélation tardive.

Bronchoesophageal fistula is an uncommon clinical problem which can either occur as a congenital or acquired condition. A 40-year-old male had productive cough with production of sputum mixed with food particles and cough when eating and drinking. There was no weight loss nor weakness. Clinical examination led to the diagnosis of a fistula between the lower esophagus and the Nelson bronchus associated with bronchiectasis. The congenital nature of this fistula was suggested by the clinical, operative and pathology findings. Postoperative recover was uneventful. Esophageal respiratory tract fistula presenting in adult life are rare and can cause severe debilitation and suppurating lung disease. Surgical treatment provides complete resolution of the symptoms. Endoscopic obliteration can be considered as an alternative to surgery.

[Encapsulated papillary carcinoma of the thyroid gland. Particular histological aspect of a case with review of the literature]. / Le carcinome papillaire encapsulé de la thyroïde. Aspect histologique particulier d'une observation avec revue de la littérature.

The authors report a case of encapsulated papillary neoplasm in the right lobe of the thyroid of a 36-year-old woman. This neoplasm was a papillary encapsulated carcinoma with variable histologic patterns not properly described in the literature. In the light of a review of the literature, the authors stress the macroscopic and histologic aspects of this tumor and they discuss the prognosis and therapeutic tools used to cure this neoplasm.

[Melanotic schwannoma. A case with review of the literature]. / Le schwannome mélanotique. Une observation avec revue de la littérature.

The authors report a case of melanotic schwannoma in a 46-year-old man after 2 years of bilateral sciatica. Surgical removal was incomplete, because of the posterior site of the tumor. The patient was alive and well, 2 years after surgical removal, with some surgical sequelae. The authors stress the diagnostic difficulties of this melanotic and review the previously reported cases in a comparative study.

[Acardiac malformation: ultrasonographic diagnosis. A case report]. / Le monstre acardiaque: diagnostic échographique. A propos d'un cas.

Acardia is an extremely rare malformation which is seen in less than 1 per cent of monozygous twin pregnancies. Pathological aspects and etiopathogenic theories concerning this malformation are reviewed on the basis of a case diagnosed in utero at 24 weeks. The value of the antenatal diagnosis of this malformation is that of monitoring the progression of the pregnancy and predicting the fate of the healthy twin.

[Correlation between epithelioid sarcoma and poorly differentiated fibroblastic synovialosarcoma]. / Rapport nosologique du sarcome épithélioïde et du synovialosarcome fibroblastique peu différencié.

The authors report an original case of tendosynovial sarcoma localizated in the side of the palm of the hand of an eight year old child. This tumor has two morphological forms. One is characteristic of undifferentiated synovialosarcoma, and the other of epitheloid sarcoma. The immuno-histochemical study confirms the diagnosis of undifferentiated synovialosarcoma. On the basis of this case and with reference to the literature, the authors suggest that epithelioid sarcoma and synovialosarcoma constitute the same entity.
