    A rare mandibular mucoepidermoid tumor case in a 57-year-old man was treated with hemimandibulectomy. Histological analysis revealed intermediate clear cells, similar to tumors at other sites, suggesting a potential origin from heterotopic salivary lobules.

    Area of Science:

    • Oral pathology
    • Head and neck oncology
    • Surgical oncology

    Background:

    • Mucoepidermoid tumors are the most common salivary gland neoplasms.
    • While typically occurring in the parotid gland, they can arise in minor salivary glands and other sites, including the mandible.
    • Understanding the histopathological and ultrastructural features is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To report a rare case of a mandibular mucoepidermoid tumor.
    • To describe the clinical, radiological, gross, and histological findings.
    • To discuss the potential genesis of these tumors, particularly in relation to heterotopic salivary tissue.

    Main Methods:

    • Case presentation of a 57-year-old male with mandibular swelling.
    • Radiographic examination (roentgenograms) to assess bone involvement.

  • Surgical treatment via hemimandibulectomy.
  • Gross pathological examination of the resected neoplasm.
  • Histological and ultrastructural analysis of tumor composition.

    • Main Results:

    • A progressive mandibular swelling with osteolytic features was observed.
    • The neoplasm was partly cystic and primarily composed of intermediate clear cells histologically.
    • Ultrastructural findings were consistent with mucoepidermoid tumors found in other anatomical locations.

    Conclusions:

    • Mandibular mucoepidermoid tumors are rare but require accurate diagnosis and surgical management.
    • The histological and ultrastructural characteristics of this case align with those of mucoepidermoid tumors elsewhere.
    • The study suggests that heterotopic salivary lobules may be the primary origin for these mandibular tumors, even if not present in the immediate surgical specimen.
