“…Small islands of odontogenic epithelial tissue can occasionally be found scattered in such a stroma. [22] OM has to be differentiated from other jaw tumors showing myxoid degeneration, such as myxoid neurofibroma, myxoid liposarcoma, and chondromyxoid fibroma. Chondromyxoid fibroma shows areas of cartilaginous differentiation, whereas myxoid neurofibromas tend to have scattered lesional cells that are S-100 positive.…”

Odontogenic myxoma comprises 3-6% of all odontogenic tumors. Odontogenic myxomas are relatively rare benign mesenchymal tumors found exclusively in the tooth-bearing areas of the jaw and are usually located centrally in the mandible. Soft-tissue localization is rarely seen and is classified as peripheral myxoma. Peripheral myxoma is slow growing and less aggressive, as compared to the central myxoma. It has a low recurrence rate. Till date, only few cases of maxillary gingival myxomas are reported in the literature. Here, we present an unusual case of primary peripheral odontogenic myxoma occurring in the gingiva of anterior maxilla in a 41-year-old female patient.

Odontogenic myxofibroma represents a rare slow-growing benign neoplasm, which usually occurs in the second and third decades of life and rarely in children or adults over 50 years of age. Myxomas in general represent from 2.3% to 17.7% of all odontogenic tumors, and myxofibromas represent a small number of all myxomas. Limited evidence is present in literature regarding the cytological diagnosis of odontogenic myxoma/myxofibroma. We hereby report the cytomorphological features of a histologically confirmed case of odontogenic myxofibroma and the pitfalls of the cytological diagnosis. A painless jaw swelling in a young boy was aspirated. Scanty mucoid material was obtained. Cytology Smears were moderately cellular and showed a population comprising predominantly of singly scattered plump to fusiform cells with bipolar cytoplasmic processes showing mild to moderate atypia embedded within dense myxoid matrix and another population of cells arranged in clusters. Case was interpreted as low grade mesenchymal tumor. Subsequent biopsy confirmed it as odontogenic myxofibroma arising in a odontogenic keratocyst. Precise interpretation of intraosseous jaw lesions FNAC may not always be possible, but an attempt should be made to broadly classify the lesion as an inflammatory lesion, cystic lesion, giant cell lesion, fibro-osseous lesion or as an odontogenic tumor. If dual population of odontogenic epithelium and mesenchymal cells embedded in myxoid matrix are identified in such aspirates, a possibility of myxoid odontogenic tumor may be suggested. Triple correlation of cytological, clinical and radiological findings can guide the surgeon for taking appropriate therapeutic decisions.

“…The appearance of apical alveolar lesions could be explained by the invasive nature of fibromyxoma. These different X-ray appearances of the fibromyxomas pose a diagnostic problem with ameloblastomas, giant cell tumors, and intraosseous hemangiomas, as described in the literature; hence, a histopathological examination that provides confirmation of diagnosis is required [13,15]. The presence of calcifications found in the histopathological examination was also observed by Miettinen et al [12].…”

“…The prevention of a relapse is strongly related to the complete resection of the lesion. The patient should be monitored for at least 2-5 years after surgery because of a high relapse rate of 25% during this period [15,[17][18][19]. For the observed case, because of the location of the soft tissue, we carried out a large resection of the tumor with an alveolar vacuum and the avulsion of the teeth embedded in the tumor.…”

--Introduction: Fibromyxomas are mesodermal tumors of dental origin. They are infrequent and are often diagnosed incidentally during radiography. Observation: A fibromyxoma was discovered in a 27-years-old patient who presented to us for a consultation for a voluminous swelling of the oral cavity which had developed over 2 years. Physical examination revealed anemia and weight loss. Oral examination revealed a voluminous gingival mass that was ulcerated and necrotic in places, with associated bleeding. The treatment consisted of a surgical resection, multiple dental avulsions, and an alveolar curettage. The histopathological examination of the resected lesion revealed an ulcerated gingival fibromyxoma with pathological calcification. Comments: Here were report a rare case of a woman with necroinflammatory-hemorrhagic and ulcerated gingival fibromyxoma, which resulted in functional and cosmetic damage, along with a literature review pertaining to this subject. The aggressiveness and the high potential of the maxillary fibromyxoma recurrence suggest that a wide surgical resection is the best treatment option to guarantee a good prognosis. Conclusion: The treatment of fibromyxoma requires surgical intervention and the diagnosis is confirmed by a histopathological examination of the resected lesion.
