AbstractA 30-year-old female presented with asymptomatic slate brown hyperpigmented diffuse macules on both the cheeks, nose, forehead, eyelids, sclera, conjunctiva and hard palate since early childhood. Nevus of Ota, are in Indian subcontinent, commonly occurs unilaterally on face. This case is being reported for its rarity and extensive involvement.
Nevus of Ota, a dermal melanocytic nevus, is common in Japanese. It is comparatively rare in Indian subcontinent. It generally presents as blue - black or gray-brown patchy/diffuse pigmentation that most commnoly occurs unilaterally on face in areas innervated by the first and second divisions of trigeminal nerves. Bilateral involvement can occur, but as a rare manifestation.
This patient has extensive bilateral pigmentation with the involvement of oral mucosa.
A 30-year-old woman presented with asymptomatic hyperpigmented macules on face since early childhood. The lesions gradually progressed with age; static since 10-12 years. Cutaneous examination revealed slate- brown hyperpigmented diffuse macules on both the checks, nose and forehead [Figure - 1]. She also had hyperpigmentation of eye-lids, sclera, conjunctiva and hard palate. There was no other associated abnormalities seen.
In nevus of Ota (Nevus fuscoceruleus ophthamo-maxillaris) the pigmentation spots usually appear in childhood and the distribution is usually, but not always, unilateral. Open angle glaucoma and malignant melanoma involving the eyes are rare associations reported. This case is being reported for its extensive bilateral and palatal involvement, which is as such uncommonly seen in Indian subcontinent.
