“…Furthermore, documented cases of melanoma presenting with accompanying poliosis reported the onset of the poliosis 1 to 2 years before presentation, unlike this presentation of congenital poliosis and development of melanoma later in life. 5 We report the first documented case of melanoma ex blue nevus originating from a longstanding subcutaneous nodule, accompanied by overlying poliosis. This unique clinical presentation and histopathological findings highlight the importance of vigilant evaluation and consideration of melanoma in atypical lesions, even in the context of longstanding, benign-appearing nodules.…”

“…In addition, reported cases of blue nevi with overlying poliosis have not been associated with progression to melanoma. 5 Although rare, there have been reports of melanoma presenting with poliosis. However, these lesions also presented with overlying pigment changes on the skin surface.…”

“…In adulthood, localized poliosis should prompt the consideration of a scalp melanoma. 19 In children, poliosis has been described infrequently with large congenital melanocytic nevi and in the setting of acquired halo nevi. [20][21][22] In both processes, poliosis may represent an inflammatory response to bulbar melanocytes.…”

Poliosis is defined as the absence of melanin in hair, and hair graying typically occurs with hair melanin reduction. Poliosis can occur at any age but presents in childhood in certain genetic and acquired conditions, with many families seeking evaluation from a pediatric dermatologist. Poliosis presents as white hair typically restricted to a certain location of the scalp. Children may also present with a reduction of expected hair pigmentation, referred to as pigment dilution, or the development of hair graying. This review aims to provide a streamlined diagnostic approach for pediatric dermatologists when presented with these hair findings. Poliosis should be recognized as a potential diagnostic feature or initial sign in many syndromes and thus can guide clinicians in diagnosing and managing conditions earlier in a patient's care. Since many of the genetic and acquired conditions that present with poliosis or hair pigment dilution have extracutaneous manifestations, early diagnosis is vital in establishing multidisciplinary care.

“…4 Poliosis circumscripta is rarely a presenting sign of the disease. Previously few cases have been described concerning the appearance of hair whitening in concomitance with the presence of a scalp melanoma, 5,6 as well as the appearance of eyelash poliosis as a clinical sign of conjunctival melanoma recurrence. Eyelash poliosis has been described as an atypical manifestation of metastatic melanoma recurrence in one patient who underwent primitive lesion excision three years before; similarly to our case, the primary melanoma was distant from the area of poliosis.…”
