title: Oral cavity eumycetoma: a rare and unusual condition.
abstract: In this short communication, we report on a 25-year-old male patient who presented with a longstanding painless swelling under the tongue. It was of a gradual onset and course, but 2 months before presentation it suddenly increased in size. Local examination revealed a tender firm pigmented mass in the midline of the mouth floor. The differential diagnosis included dermoid cyst, salivary glands tumours, mucocele or vascular anomaly. The investigations done were not conclusive. He underwent surgical exploration, and mycetoma was a surgical surprise. Although mycetoma is common problem in the tropics, such a presentation is a rarity. In tropical and subtropical regions, mycetoma should be considered in the differential diagnosis of oral cavity masses.
