Introduction: Odontogenic myxoma is a rare benign mesenchymal tumor of the maxillers. Its growth is slow but locally invasive. Its clinical and radiological manifestations are variable and non-specific and may cause confusion with other clear radio injuries. We report a case of a 24 years old female patient with odontogenic myxoma of the left jaw. The patient presented a gradually progressive firm swelling on the lower left side of the jaw. The CT scan showed a heterogeneous osteolytic process of the left body of the mandible ; with irregular contour and destruction of the corticale. The biopsy was in favor of an odontogenic myxoma. We proceeded with a conservative surgical excision of the tumor with curettage of the residual cavity and a mini plate was fitted. The histological examination of the tumor confirmed the diagnosis.
Discussion:
Most of the face tumors, such as myxoma, are manifested by a tumefaction, deformation, and/or facial asymmetry. The radiological aspect is quite polymorphic and can sometimes be worrying and misleading.
The odontogenic myxoma is a diagnosis of elimination, many benign or malignant maxillary tumors may have a myxoid appearance. The confirmation of the diagnosis is anatomo-pathological.
The treatment of myxoma is surgical. A conservative approach can be proposed to the patient, with excision of the tumor and curettage, for small no invasive tumors. However, if the tumor is large and invasive a radical surgery is recommended. Rigorous supervision is required during the first two years of operation.
