Mucosal malignant melanoma (MMM) is an uncommon tumour of the head and neck region. MMMs are much more agressive than cutaneous malignant melanomas (MM). Complete surgical excision of the tumour is difficult due to complex anatomy of the head and neck region. Therefore early diagnosis and early treatment deserve a special significance. Oral cavity MMMs account for 0.5 % of the oral malignancies. MMM of the mandibular gingiva is also very rare. Although various types of cutaneous MMs have been clearly described, data on MMMs is quite limited due to the lack of large series. In this article, we report a 29 year-old female patient who was previously operated for MMM of the mandibular gingiva. She was referred to our institution with locoregional recurrent disease. We discuss clinical and histopathological features of MMMs and therapeutic modalities in line with the literature.
