Multiple fibromyxomas of the jaws: A case report

Segmental resection with primary reconstruction using patient- specific implant for odontogenic fibromyxoma: An illustrative rare case from Nepal

INTRODUCTION

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.

CASE PRESENTATION

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.

DISCUSSION

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.

CONCLUSION

This report introduces a novel technique whereby patient-specific implants are employed as the primary method of reconstruction following segmental resection.

Conservative Management of Odontogenic Fibromyxoma of the Maxilla: A Case Report

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.

Odontogenic fibromyxoma: A case report in myasthenia gravis patient and review of the literature

INTRODUCTION AND IMPORTANCE

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.

CASE PRESENTATION

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.

CLINICAL DISCUSSION

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.

CONCLUSION

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.

Multiple calcifying hyperplastic dental follicles: a major diagnostic consideration in multiple pericoronal lesions - report of two cases

Background

Pericoronal radiolucent lesions are a common radiographic finding, but it is rare that they occur in multiple forms. Multiple calcifying hyperplastic dental follicles (MCHDF) are entities with few cases described to date; nevertheless, they appear to have a very particular phenotypic pattern.

Cases presentation

Case 1: A 10-year-old male was evaluated radiographically, revealing four impacted canines, each accompanied by unilocular pericoronal radiolucency. Case 2: A 16-year-old male was planning orthodontic treatment; following his radiological evaluation all third molars were found to be accompanied with pericoronal radiolucencies. Enucleation, and third molar removal along with the pericoronal tissue were the respective treatments. Microscopically, in both cases, the specimens shown odontogenic epithelium, and type I and II calcifications in the hyperplastic follicles, all these characteristics were consistent with MCHDF.

Conclusion

Although MCHDF are a rare entity, they must be considered in the differential diagnosis of multiple pericoronal lesions. Under the light of the current evidence, the histological findings may be relatively heterogeneous, but their integration with both the clinical data, which are apparently particular, and with the radiographic characteristics, can lead to a definitive diagnosis.

Hibernoma in the clavicular fossa: A case report and literature review

A hibernoma is a benign soft tissue tumor consisting of brown adipose tissue. The tumors are mostly located in the thigh, back, and shoulder region. They are rarely found in the supraclavicular fossa. We report a 39-year-old woman who presented with a painless, slow-growing mass on the left supraclavicular fossa for nearly 15 years. Magnetic resonance imaging (MRI) showed an inhomogeneous round mass with a slightly hyperintense signal on fat-suppression T2-weighted imaging that compressed the adjacent tissues and subclavian vessels. Computed tomography angiography indicated a rich blood flow signal. Postoperative histology confirmed the diagnosis of a hibernating tumor. Although comprehensive imaging is important in the determination of tumor for the size, location, and nature, computed tomography angiography provides clear indication of the vascularity of the tumor, which provides vital clinicopathologic data for surgeons.

Fibromyxoma of the Jaw: Case Report and Review of the Literature

We report a case of fibromyxoma of the mandible, a rare benign odontogenic tumor. Our patient presented in the first trimester of pregnancy with a large mass in the right body of the mandible exhibiting displacement of teeth and destruction of an extensive area of the mandibular bone. The mass was biopsied and diagnosed as a fibromyxoma. The large size of the tumor dictated a wide mandibular resection. We will review the clinical, radiographic, and histologic features of fibromyxoma and discuss its differential diagnoses. In addition, we will provide an overview of patient management. Fibromxyoma is a benign gnathic tumor that can be locally aggressive. To ensure appropriate treatment, it is important to distinguish this neoplasm from other mimickers in which myxoid, spindle mesenchymal cell proliferation is prominent.
