[Sarcoïdose in patient with chronic hepatitis C treated with pegylated interferon]. / Sarcoïdose chez un patient traité par interféron pégylé pour une hépatite chronique C.

Induced sarcoïdosis during therapy with interferon for chronic viral hepatitis C involves mainly by isolated cutaneous lesions or with lung lesions. Systemic forms are very rare. We report an observation. A 50-year-old patient developed a systemic sarcoïdosis two months after the end of treatment for hepatitis C with pegylated interferon and ribavirin with lung, joint and hepatic manifestations. After starting corticosteroid therapy, the evolution was favourable. Induced sarcoïdosis by interferon therapy is rare, treatment necessitates stopping interferon, and sometimes corticosteroid therapy.

[Chondroma of the acromion: an unusual localization]. / Le chondrome de l'acromion : à propos d'une exceptionnelle localisation.

The scapula is an uncommon site for a chondroma. We report the case of a chondroma in the left acromion, which presented as a painful shoulder in a 19-year-old teenager. The diagnosis was suspected on radiographs and CT scan and confirmed by histological findings.

Acute spontaneous subdural hematoma: an unusual form of cerebrovacular accident.

An acute subdural hematoma is commonly regarded as a complication of a head injury, and bleeding is associated with contusion or laceration of the bridging vein in the subdural space. Occasionally, reports describe non traumatic acute subdural bleeding from the rupture of cerebral aneurysm or vascular malformation. However, acute spontaneous subdural hematomas (ASDH) of arterial origin, without any traumatic history or vascular anomaly, are rarely reported in literature. Here we describe two cases who presented with acute signs of intracranial hypertension secondary to a spontaneous acute subdural hematoma in which spontaneous bleeding from a small cortical artery was seen during operation.
