Perinevoid alopecia has been described as an associated alopecia surrounding a pigmented nevus due to an inflammatory response against nevus structures. It is described as a part of other nevocentric phenomena in which a cellular inflammatory response against nevus antigens develops. A 35-year-old male presented with a unique area of non-scarring alopecia surrounding an asymptomatic, pigmented nevus with a 1-month evolution. Trichoscopic and histologic findings were compatible with alopecia areata (AA). One month after excision, hair regrowth was reported by the patient. We concluded that perinevoid alopecia is an extremely rare clinical presentation of AA associated with a central, pigmented nevus where a cellular inflammatory response is triggered against hair follicles, nevoid cells, and melanocytic structures.

“…From a clinical point of view, halo nevi develop in several stages, depending on which the dermoscopic appearance is different, as we detailed above. Histologically, four forms are described without always having a dermoscopic correspondence: (a) inflammatory, (b) noninflammatory, (c) halo nevus without halo, (d) halo dermatitis around a melanocytic nevus, and a classification focused on inflammatory infiltrate is presented below [ 20 , 21 ]. The clinical correlation is very important because some nevi may demonstrate marked inflammation, but, clinically, no halo is visible, and other, noninflammatory halo nevi, may demonstrate a halo, but histologically no inflammatory infiltrate.…”

Halo nevi, known as leukoderma acquisitum centrifugum, Sutton nevus, leukopigmentary nevus, perinevoid vitiligo, or perinevoid leukoderma, together with vitiligo and melanoma-associated hypopigmentation, belong to the group of dermatoses designated as immunological leukodermas. The etiology and pathogenesis of halo nevi has not been fully elucidated. There are several mechanisms through which a lymphocytic infiltrate can induce tumoral regression. In this review, we aimed to update the knowledge about Sutton nevi starting with the clinical appearance and dermoscopic features, continuing with information regarding conventional microscopy, immunohistochemistry, and the immunological mechanisms responsible for the occurrence of halo nevi. We also included in the article original unpublished results when discussing dermoscopic, pathologic and immunohistochemical results in halo nevi. Sutton nevi are valuable models for studying antitumor reactions that the human body can generate. The slow and effective mechanism against a melanocytic skin tumor can teach us important lessons about both autoimmune diseases and anticancer defenses.

<p>Nevus of Ota is dermal melanocytosis, generally presents as blue-black or gray-brown patchy diffuse pigmentation. Most commonly occurs unilaterally on face in areas innervated by the first and second divisions of trigeminal nerves. Bilateral involvement and oral mucosal involvement can occur, but as a rare manifestation. Nevus of Ota may be very rarely associated with the nevus of Ito and other extra cutaneous features. The halo nevus may be seen in congenital or acquired melanocytic nevi. Presence of halo nevus in conjunction with two different dermal nevi is not reported till date. We are reporting 19 year old female presented with bilateral Nevus of Ota with oral mucosal involvement and associated nevus of Ito and halo nevus.</p>
