Jadassohn's nevus in a newborn: surgical treatment or conservative tactics

BACKGROUND: Jadassohn's nevus (seborrheic nevus, nevus of the sebaceous glands) is a hamartoma which is mainly localized on the scalp and face skin. At birth, it looks like a barely noticeable light yellow plaque which significantly increases at the puberty period under androgenic stimulation. The histological picture of Jadasson's nevus is characterized by changes in the epidermis in the form of acanthosis, papillomatosis, hyperkeratosis, and a large number of hyperplastic sebaceous glands. Pluripotent epithelial cells, which are part of the hamartoma, may provoke the growth of secondary benign and malignant tumors. This nevus may be manifested by Schimmelpenning–Feuerstein–Mims syndrome which can damage the nervous system and eyes. Currently, there are no uniform recommendations for the management of patients with Jadassohn's nevus.

CLINICAL CASE DESCRIPTION: In this article, we present our own experience of treating two children discussed pathology. The first boy had a radical surgery at the age of 16 days of life because of large dimensions of the nevus and a significant cosmetic defect. Removal of the formation at the neonatal period has prevented the development of rough postoperative scars and promoted good cosmetic outcome due to high elastic and regenerative properties of baby's skin. In the second child, Jadasson's nevus looked like a barely noticeable light yellow plaque; therefore, conservative tactics was chosen for this patient. Both children were consulted by a neurologist and an ophthalmologist who found no pathology in the nervous system and in the vision organs.

CONCLUSION: The described two clinical examples demonstrate the need for individual and multidisciplinary approaches in the management of patients with Jadasson's nevus. Active surgical tactics should be applied because of a significant cosmetic defect rather than for the prevention of malignant transformation which is met in less than 1% of cases.
