Skinsarcoidosis: A trick for primary case physicians

[Scar sarcoidosis: a usually progressive disease (about a case)]

The sarcoidosis is a systemic granulomatous disease. It is usually characterized by skin manifestations which may be suggestive of progressive sarcoidosis with visceral involvement. We here report a case of pulmonary sarcoidosis revealed by the reactivation of an old cutaneous scar following a trauma occurred 20 years earlier. Radiological assessment showed mediastino-pulmonary sarcoidosis stage 2. The diagnosis of sarcoidosis should be suspected in patients with any recent scar modification in order to establish early management.

Lymphadenopathy and granulomas: benignancy of malignancy and differential diagnosis with endobronchial ultrasound-transbronchial needle biopsy 19G needle fine-needle aspiration biopsy

Endobronchial ultrasound (EBUS) is a very useful tool for the diagnosis of lymphadenopathy of the mediastinum. Nowadays, EBUS can substitute video-assisted thoracic surgery when a 19G needle is used. Several studies have provided data for efficient diagnosis not only for lung cancer, but for also sarcoidosis, tuberculosis and lymphoma. We present five cases of EBUS-transbronchial needle biopsy 19G needle used for the diagnosis of mediastinum lymphadenopathy. We present not only the pathological diagnosis, but also the steps for the differential clinical and pathological differential diagnosis for sarcoidosis, tuberculosis, cancer metastasis, respiratory infection and lymphoma.
