Abstract
The author reports a rare case of submandibular salivary gland melanotic pigmentation in a patient with nevus of Ota.
The 42-year-old man with nevus of Ota had suffered from sialolithiasis of the submandibular salivary gland. Resection of the submandibular salivary gland was done and melanotic pigmentation was found.
Histopathological examination revealed the melanin not in the gland cell but in the interstitial connective tissue.
Nevus of Ota usually affects areas innervated by the first and second divisions of the trigeminat nerve, but rarely those innervated by the third division. Involvement of the submandibular salivary gland is rare because the gland is innervated by the third division of the trigeminal nerve.
