Odontogenic myxomas often have a distinctive radiographic presentation described as a "soap bubble", "tennis racket", or "honeycomb" pattern. Less frequently, examples of odontogenic myxomas with a "sunray" or "sunburst" pattern have been reported. Because malignant entities such as osteosarcomas more classically present with a sunray/sunburst appearance, odontogenic myxomas are rarely considered in the radiographic differential diagnosis of a sunburst lesion. The objective of this paper is to report a case of an odontogenic myxoma presenting with a sunburst appearance and to review similar reported cases in the literature. To the best of the authors' knowledge, this additional case of an odontogenic myxoma presenting with a sunburst appearance brings the total number of sunray/sunburst cases reported in the English language literature to 21.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.

Objective: and rationale: Odontogenic myxoma is an uncommon odontogenic tumor with locally aggressive behavior. The clinicopathological studies of odontogenic myxoma in Asian countries are very limited and only few studies have investigated the immunohistochemical profiles of the tumor. This study aims to investigate the clinicopathological and immunohistochemical features of odontogenic myxoma at the Faculty of Dentistry, Mahidol University over a 15-year period.

Odontogenic myxoma of the mandibular condyle is a rare tumor that requires complete surgical resection because of the tendency for recurrence. The right mandibular condyle was resected to remove the myxoma. The author performed immediate condylar reconstruction using a costochondral graft (CCG), and stable temporomandibular joint (TMJ) function and occlusion were achieved.

The acetylation of histones H2A on lysine 5 (H2AacK5) and H3 on lysine 27 (H3AcK27) modulate several cellular mechanisms through the p300 enzyme in pathological lesions; however, their role in odontogenic lesions has not been addressed. This study aims to evaluate the immunoexpression of p300, H2AacK5, and H3AcK27 in samples of ameloblastoma (AMB) (n = 30), odontogenic keratocyst (OK) (n = 15), adenomatoid odontogenic tumor (AOT) (n = 10), odontogenic fibroma (OF) (n = 8), calcifying odontogenic cyst (COC) (n = 8), odontogenic myxoma (MIX) (n = 10), and ameloblastic fibroma (AF) (n = 06). The percentage of p300-positive cells was higher in AOT and decreased in COC, OK, AMB, AF, OF, and MIX.
