What is dermal Melanosis?
Dermal melanocytosis occurs when melanocytes fail to complete their migration from the neural crest to the basal layer of the epidermis. The melanocytes end their migration in the middle to lower dermis, where based on the Tyndall effect, their brown pigment gives the skin’s surface a blue-grey color.
How do you treat dermal Melanocytosis?
What is the treatment for dermal melanocytosis? Dermal melanocytosis is benign and does not require treatment. Usually the discolouration spontaneously disappears by the time the child reaches 4 years old. Persistent dermal melanocytosis tends to be larger and persist for many years or indefinitely.
How do you treat dermal hyperpigmentation?
The best treatment approach to this form of hyperpigmentation is prevention using a combination of sun avoidance and topical skin care products such as a sunscreen, antioxidant (C E Ferulic by SkinCeuticals), and retinoids (retinol, Retin-A).
Are there any unusual cases of dermal melanocytosis?
A brief review of the clinical spectrum of the dermal melanocytoses is undertaken and three illustrative cases are described: a case of congenital naevus of Ota, a case of acquired bilateral naevus of Ota-like macules, and an unusual case of a congenital dermal melanocytotic lesion on the left had which began to spread in adulthood.
How is oculodermal melanocytosis related to metastasis?
However Shields et al found that patients with uveal melanoma associated with oculodermal melanocytosis have a twice as likely risk for metastasis compared to those without melanocytosis. Oculomucodermal melanocytosis (Nevus of Ota) is a benign dermal melanocytosis, that results in hyperpigmentation of the sclera and ipsilateral face.
When does dermal melanocytosis occur in newborns?
Abstract Purpose of review: Dermal melanocytosis is commonly seen in the newborn period and is frequently a concern to parents and providers. Four clinically distinct entities are recognized: nevus of Ota, nevus of Ito, Mongolian spots, and dermal melanocyte hamartoma.
How is melanocytosis related to lysosomal storage disease?
Background The potential association of dermal melanocytosis with lysosomal storage disease in infancy is an uncommonly known and poorly understood entity. Observations We describe 2 infants with extensive dermal melanocytosis in association with GM 1 gangliosidosis type 1 and Hurler syndrome, respectively.
