A Case of Nevus of Ota in Trinidad and Tobago.

Oculodermal melanocytosis, also known as Nevus of Ota, was extensively described in 1939 and is characterized by unilateral, irregular, bluish-black cutaneous pigmentation along the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. This condition is non-hereditary and occurs more commonly in females. To the best of our knowledge, we report the first documented case of Nevus of Ota in Trinidad and Tobago, presenting in a 67-year-old female with characteristic pigmentation and no family history of similar conditions. The diagnosis was confirmed clinically, and the patient was counseled on potential ocular and dermatological complications. This case highlights the importance of recognizing rare dermatological conditions in diverse populations to facilitate timely diagnosis, appropriate management, and effective monitoring for potential complications.
