Fibromyxoma of the jaw is a very uncommon benign mesenchymal odontogenic tumour that can be aggressive locally. In the present report, a 14-year-old female patient presented to our college hospital with the complaint of swelling and pain. Initially, a panoramic radiograph indicated multilocular radiolucency, and a CBCT examination revealed buccal cortical plate erosion. Microscopic examination revealed odontogenic fibromyxoma after incisional and excisional biopsy. The clinical features, panoramic radiograph and histological findings of this case have all been covered in this article. [ABSTRACT FROM AUTHOR]

Odontogenic fibromyxoma (OFM) is a round and locally invasive neoplasm predominantly seen in the mandible. Though radiographic appearance is variable, definitive diagnosis is based on correlation with histopathological examination. Surgical approach is the treatment of choice. For reconstruction, patient-specific implant (PSI) has lately been developed as a crucial help. This case report presents a 19 year old female patient with odontogenic fibromyxoma highlighting its clinical, radiographic, histopathological features along with rehabilitation using patient specific implants reducing the complexity and related morbidities of reconstructive procedures. Surgical repair and reconstruction of defects in cranio-maxillofacial region is challenging. The described treatment eliminates the need for bone grafting, shows optimal results owing to the shorter rehabilitation time and more accurate fits. This report introduces a novel technique whereby patient-specific implants are employed as the primary method of reconstruction following segmental resection. • Odontogenic fibromyxoma is a rare odontogenic neoplasm mostly found in the mandible. • Correlation of history, clinical features, radiographic finding and histopathological examination is needed for definitive diagnosis. • Surgical resection is the treatment of choice. • Patient-specific implant eliminates the need for bone grafting, shows optimal results owing to the shorter rehabilitation time and more accurate fit.

Odontogenic fibromyxoma typically presents as painless swelling in the jaw, and clinically, it grows slowly, becoming benign and asymptomatic. It causes the cortical plates to expand gradually, which leads to mobility and drifting of the teeth. Root resorption is also common. The tumor is locally aggressive in nature. It is also known to have a high recurrence rate. We present the case of a 30-year-old female patient who was diagnosed and treated for odontogenic fibromyxoma of the maxilla conservatively with enucleation. The radiograph showed a multilocular lesion, which can be confused with ameloblastoma, aneurysmal bone cyst, or odontogenic keratocyst. Hence, with proper clinical, radiographic, and histopathological examination, a correct diagnosis can be made and adequate treatment can be planned., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Hurkat et al.)

An inflammatory gingival mass surrounding resorbing teeth was diagnosed via biopsy in a 9-year-old domestic shorthair cat. A dorsal rim excision was performed to remove the entire mass with associated teeth and bone. Histopathological diagnosis of the en bloc tissue revealed an odontogenic fibromyxoma. Extensive literature review revealed few case reports of companion animals with this neoplasm, and none in a feline patient. This report documents the clinical presentation, diagnostic differentials, surgical therapy, and long-term follow-up of an odontogenic fibromyxoma in a cat. [ABSTRACT FROM AUTHOR]

Odontogenic fibromyxoma is a rare odontogenic tumor of mesenchymal origin. It is composed of large amounts of intercellular substance rich in acid mucopolysaccharides, making it locally very aggressive and with high recurrence rates following conservative excision. Its histological and radiological features make it difficult to differentiate from other odontogenic tumors and, occasionally, may be misinterpreted as a malignant lesion. Although the origin of a myxoma is still obscure, its origin from the dental follicle seems to be the most reasonable explanation. We report a case of odontogenic fibromyxoma of maxilla in a 32-year-old female patient.

Background. Odontogenic fibromyxoma is an uncommon benign tumor arising from the maxillofacial bones. Fibromyxomas are rare in children under 10 years of age. Although this tumor is reported most frequently in the mandible for the general population, it has rarely been reported in the mandible in children <10 years of age. Methods. We reviewed the 39 reported cases of odontogenic fibromyxoma in children under the age of 10. We add 1 case to the literature. Results. This case represents the seventh case of odontogenic fibromyxoma of the mandible in a child under the age of 10 years reported in the English literature. Conclusion. A case of pediatric odontogenic fibromyxoma in the mandible is described. Although rare in the pediatric population, odontogenic fibromyxomas should be included as a differential diagnostic consideration when evaluating tumors of the maxillofacial skeleton. Accurate pathologic diagnosis is critical to ensure proper management. [ABSTRACT FROM AUTHOR]

Odontogenic fibromyxoma (OFM) is a benign, locally invasive and aggressive nonmetastasizing neoplasm of jaw bones. They are considered relatively rare and known to be derived from embryonic mesenchymal elements of dental origin. Treatment of OFM depends on the size of the lesion and on its nature and behavior. Varying treatment modalities ranging from curettage to radical excision have been documented. Aim; This paper is a review of management of 8 pediatric patients with histologically diagnosed OFM at a Nigerian tertiary health care facility. This was a retrospective study of all patients aged 15 years and below who presented to the Oral and Maxillofacial Surgery Clinic of Aminu Kano Teaching Hospital, Kano, over a 5-year period (January 2008 to December 2012), with a histologic diagnosis of OFM. The information obtained included patients' demographics, as well as their clinical characteristics such as the anatomical site and side of lesions. Other information collated included presenting features, the onset of symptoms, type of treatment carried out, as well as treatment outcome. The data were analyzed and the results presented as frequencies and percentages. Among the 8 patients with OFM, more males (n = 5/8; 62.5%) were affected than females (n = 3/8; 37.5%). The mandible (n = 5/8; 62.5%) was the most frequent site of occurrence, and the anterior mandible was the most favored location (n = 4/8; 50%). Seven patients had excision of the lesion with peripheral ostectomy of the underlying bone while only one patient had a bone resection. These patients have been followed up for at least 1 year, and no recurrence was observed throughout the follow-up period. OFM causes gross facial disfigurement and may result in the destruction of the entire jaw bone; the impact of which may be grave for a growing child. Prompt surgical intervention and follow-up have proven to be adequate management protocol. [ABSTRACT FROM AUTHOR]

Odontogenic fibromyxoma is generally slow-growing, benign, asymptomatic, present with painless swelling in the jaw. Pain is mostly seen in the case of infection, adjacent anatomical structures or neural involvement. When the English-language literature is searched, only 62 cases are found about odontogenic fibromxoma which means it is really rare pathology. We describe a case of odontogenic fibromyxoma in a 29-year-old female with Myasthenia Gravis (MG) who referred to oral and maxillofacial surgeon with increased swelling in the anterior region of the mandible. Clinically, there was swelling in the mouth that caused bone expansion. On the radiological examination, a well-circumscribed, radiolucent area causing displacement of the tooth roots was observed. After clinical and radiological examinations, the operation was done under local anesthesia. The excised lesion was sent for histopathological investigation and the patient was followed up clinically and radiologically for 3 years. The clinical and radiological properties, differential diagnosis, treatment options and prognosis of odontogenic fibromyxomas are also discussed after the case presentation along with literature review. • Odontogenic fibromyxoma is a rare tumor seen in jaw. • Odontogenic fibromyxoma can have fatal consequences when seen in the upper jaw. • A definitive diagnosis is difficult, so biopsy is essential. • The recurrence rate is high, so it requires long-term follow-up.
