Platelet-derived growth factor type BB and collagen matrix for soft tissue reconstruction after muco-epidermoid carcinoma removal: a possible therapeutic option.

Muco-epidermoid carcinoma (MEC) is a rare malignant tumor occurring in major and minor salivary glands. The described case shows a patient undergoing tumor resection without neck dissection. A quick diagnosis performed through clinical investigation and incisional biopsy revealed the nature of the tumor. A porcine collagen matrix was applied after the surgery in order to improve soft tissue healing. The matrix was saturated with platelet-derived growth factor type BB in order to favorite healing process and then fixed on the palate with a dental support device. Follow-up visit performed at first, second, and third weeks highlighted a quick healing of oral mucosa. Here reported is a case of a 34-year-old man who developed a muco-epidermoid oral carcinoma localized in the left upper jaw palatal side. The clinical, radiographic, and histopathologic findings, plus differential diagnoses of the case and reconstructive treatment options are also presented.
