Cutaneous Infantile Haemangiomas with Intracranial and Intraspinal Involvement: A European Multicentre Experience and Review.

Infantile haemangiomas are very common benign tumours in the first months of life. They are mostly cutaneous; however, extracutaneous lesions are possible, and occur in very rare cases in the central nervous system. A European multicentre observational retrospective study was conducted in the last 5 years. Seven patients with intracranial or intraspinal infantile haemangiomas were selected and treated with oral propranolol. Propranolol was interrupted after complete or almost complete resolution of infantile haemangiomas. All patients tolerated the treatment well without side-effects. Central nervous system infantile haemangiomas are probably underestimated due to the frequent absence of symptoms and their spontaneous involution. However, they should be investigated in case of segmental cutaneous infantile haemangiomas, particularly on the head, neck, upper trunk, lumbar or sacral area in order to diagnosis intra-central nervous system involvement at an early stage.

Erythema Multiforme-like Secondary to Paraphenylenediamine Due to Henna Tattoo Plus Residual Hypopigmentation.

Temporary henna tattoos or pseudotattoos have become increasingly widespread among children and adolescent. A generalized skin reaction, type erythema multiforme-like reaction is unusual, and rarely reported. We describe the case of a 7-year-old boy who reported erythematous papular bull's-eye shaped lesions and consolidated edema primarily in the upper and lower extremities. These lesions were compatibles with erythema multiforme-like reaction. He also showed an erythematous-eczematous lesion on his leg, shaped like a dolphin. In this area, a temporary henna tattoo was painted 1-month earlier. Patch test was positive for paraphenylenediamine (PPD). Skin reactions due to henna are rare. Most of the reactions are due to additives, especially PPD, an aniline derivative, which is added to speed up the process of skin dyeing and to give a darker brown to black color ("black" henna). As henna tattoos are becoming increasingly popular, prevention requires the annual provision of information to consumers, especially young people and their parents.
