Pedunculated Lesion of the Scalp with Surrounding Long, Dark Hair in a Newborn

Case Presentation A female patient presented at birth with a painless bulky mass located on the vertex. She was a term baby with a normal antenatal history. The child was otherwise healthy. Physical examination showed a single, well-defined purplish-red tumoral lesion with arborizing telangiectasias over the surface (Fig. 1). It was located on the parieto-occipital region, 5 · 3 cm in size and was firm on palpation, with no apparent underlayingbonydefect.Radiologic investigations, including transfontanellar cranial ultrasonography and cranial magnetic resonance imaging, revealed no malformations of the central nervous system and demonstrated a minimally enhancing subcutaneous soft-tissue mass with a focal destructive remodeling of the outer table (Fig. 2). Abdominal ultrasonography showed no abnormalities. A biopsy was performed, and histopathological examination of hematoxylin-eosin and Masson’s trichrome stained sections showed a well-circumscribed mass. Higher power views are seen in Figs. 3 and 4.
