[Pseudotumor presentation of pulmonary sarcoidosis apropos of 3 cases]. / Présentation pseudo-tumorale de la sarcoïdose pulmonaire à propos de trois cas.

Pseudotumoral manifestations in the thorax is an unusual presentation of sarcoidosis. We report three such cases including two which mimicked pulmonary metastases with a classic image of multiple lesions in two women aged 31 and 30 years. In the third case, a 51-year-old male smoker had an opacity in the upper left lobe on chest x-ray then developed endobronchial hemorrhage suggestive of a primary bronchogenic cancer. In most cases, bronchial or transbronchial biopsies are sufficient for diagnosis. Surgical biopsy may be required however to eliminate the possibility of tumoral proliferation or an other granulomatous etiology.
