[A variety of lymphomatoid granulomatosis, pseudosarcoid granulomatosis. An anatomo-clinical observation with an ultrastructural study].

A case of sarcoid-like granulomatosis involving the lung, skin and a large cervical vessel is presented. The patient died 4 years after the beginning of the disease with a diffuse angioimmunoblastic lymphadenopathy and a sarcomatous change. Although peculiar histological lesions were seen, with a majority of epithelioid and giant Langhans cells, the extra-pulmonary involvement and the poor prognosis were similar to those of the typical lymphomatoid granulomatosis (Liebow's disease).
