A Rare Case of Oral Cavity Eumycetoma

Ann Maxillofac Surg. 2023 Jan-Jun;13(1):108-112. doi: 10.4103/ams.ams_242_22. Epub 2023 Jul 12.


Rationale: Mycetoma is a chronic granulomatous infection that involves the skin and subcutaneous tissue which presents as an abscess with multiple draining sinuses. It is common in the tropical and subtropical regions where the conditions favour the growth of the soil saprophytes - fungi and bacteria.

Patient concerns: We report the rare case of a 62-year-old patient who presented with a soft-tissue overgrowth in the mandibular posterior ridge area for eight months.

Diagnosis: The patient was diagnosed with eumycetoma, with foreign-body reaction based on clinical and histopathological examination which revealed characteristic brown-coloured amorphous grains.

Treatment: The lesion was surgically excised under local anaesthesia.

Outcomes: On the seventh day post-operative follow-up, the patient was relieved of pre-operative symptoms and the surgical site had healed well.

Take-away lessons: This particular case of eumycetoma had an unusual site and appearance, making the clinical diagnosis confusing with other reactionary lesions of the oral cavity.

Keywords: Oral cavity eumycetoma; oral fungal infection; oral mycetoma.
