[Cranial fasciitis of childhood]. / Fasciite du cuir chevelu (cranial fasciitis) de l'enfant.

INTRODUCTION: A nodule of the scalp in a child of less than eleven years should evoke a cranial fasciitis among other serious diagnoses. OBSERVATION: A four-month old infant had a firm and pink nodule at the left parietal level, exhibiting a slow growth since two months. It was excised. The pathologic sample showed spindle-shaped cells within a myxoïde matrix, with a strong reactivity for smooth muscle actin (immunohistochemical analysis). Diagnosis of cranial fasciitis was made. Due to the results of pathology, it was possible to rule out the diagnosis of sarcoma, therefore, no complementary work-up was performed. Evolution was favorable. DISCUSSION: Cranial fasciitis is a diagnosis to be considered when confronted with a firm nodule of the scalp in a infant or a young child, with or without bone involvement. This is a benign lesion but worrying pathological signs may exist, making diagnosis of benignity difficult. Exeresis of the lesion, even incomplete, protects the child from possible recurrence. Evolution is always good.

[Thoracic radiodermatitis in interventional cardiology. Apropos of 6 cases]. / Radiodermite thoracique en cardiologie interventionnelle. A propos de 6 cas.

The aim of this study is to describe thoracic radiodermatitis, a rare but not to be forgotten complication of interventional cardiology. The appearances are variable, from often oval-shaped erythema to cutaneous necrosis, with risk of chronic ulceration and malignant degeneration. The authors report 6 cases observed in 1997 after coronary angioplasty. Complex and long procedures are the main causes of this complication. Prevention requires a contribution from all the medical cardiological team, for the diagnosis, determining the indication of the type of revascularisation and for limiting the dose of X-radiation administered.
