[Cranial fasciitis of childhood].
BACKGROUND
A nodule of the scalp in a child of less than eleven years should evoke a cranial fasciitis among other serious diagnoses.


METHODS
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.


CONCLUSIONS
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.
