[Tracheo-bronchial granular cell tumors. Apropos of 4 cases].

We have seen four cases of granular cell tumor (Abrikossoff's tumour) and it is recalled that these tumours are most often discovered fortuitously by bronchoscopy in the tracheo-bronchial region because they have a non specific clinical presentation. The cytological and histological characteristics enable an accurate diagnosis but there are problems posed as to the histogenesis of these tumours. With a tumour with a slow progression regular surveillance with regular biopsies seems preferable as in certain cases the tumour regresses spontaneously or disappears after ablation with the forceps. A good alternative approach is destruction of the tumours with a laser in certain complicated forms which enables one to avoid surgical excision.

[Granular cell pituicytoma (choristoma) of the pituitary stalk].

A case of granular cell tumour in the pituitary stalk is described marked by the sudden loss of visual acuity in the left eye, followed by the right years later. A comparison with 17 cases previously published and with cases of asymptomatic granular cell nodules leads the authors to suggest the term granular cell pituicytoma. They discuss the place of this neoformation among other systemic granular cell tumours (granular cell myoblastoma). Fifteen patients were operated on, complete excision being carried out in only three (including the case published). Whether complementary cobalt therapy is useful remains problematical since very few cases have been published because of the slow development of the neoplasm.

[Primary maxillary location of myoblastoma].

The authors report the case of a myoblastoma with multiple successive and rare localisations: maxilla, cheek, lymphatics, lungs, liver and hyoid bone, with a fatal course over 28 months. They recall the possible malignancy of this tumour even in the absence of histological criteria and suggest its classification on bases which at present are only clinical.

[Granular cell myoblastoma].

Authors report a case of multiplex myoblastoma of the skin observed at a male patient aged 34. Epidermies covering the tumour histologically did not show hyperplasia considered to be characteristic. 8 years after the removal of the tumour the patient is well.

[Granular cell tumor of the vulva].

Granular cell tumor is a relatively uncommon entity of unknown etiology and uncertain histogenesis. A case of granular cell tumor of the vulva is presented with a discussion of the clinical features, pathological characteristics and the histogenic theories of its origin.

Transnasal excision of a neurohypophyseal tumor.

Neurohypophyseal tumors are rare. A case of a glioma of the neurohypophysis is presented. The tumor closely resembled pituicytomas or infundibulomas. Management of these lesions poses special problems as their natural history is unclear. This tumor was excised via the transnasal, transphenoidal route and there has been no recurrence during the subsequent thirty months. The transnasal approach for posterior lobe tumors appears to be acceptable for those confined to the sella turcica or displaying minimal suprasellar extension. The literature is reviewed.
