Published: July 2024

Squamous odontogenic tumour-like proliferations (SOTLPs) in the wall of odontogenic cysts are rare occurrences. Due to the histopathological similarity of these proliferations to neoplasms, such as squamous odontogenic tumour, intraosseous well-differentiated squamous cell carcinoma, and acanthomatous ameloblastoma, their correct elucidation is of paramount importance to avoid unnecessary and unwanted treatment. SOTLPs are uncommon in dentigerous cysts and rare in those that occur in the maxilla particularly the anterior region. This paper presents a case of maxillary dentigerous cyst involving 33 and a mesiodens in a 32 year old male which on histopathological examination showed SOTLPs in a dentigerous cyst.

To date, pagetoid spread-the proliferation of pagetoid cells in intraepidermal lesions, as observed in secondary extramammary Paget's disease-has not been reported in squamous epithelium derived from the extension of head and neck carcinomas. Herein, we report a case of pagetoid squamous cell proliferation associated with a primary intraosseous carcinoma (PIOC) arising in the periapical lesion of the maxilla, a finding not reported previously. A 60-year-old man presented with prostate adenocarcinoma and bilateral pubic bone, ilium bone, and sacral bone metastases.

Malignant transformation arising in the background of jaw cysts is a rare and often misdiagnosed condition, particularly when developing from residual root-derived cysts. We present a case of epithelial malignancy originating from a residual root-derived cyst in the mandible of a man around 50 years old. Histological evaluation of the sections revealed that the epithelial lining of the cystic lesion contained well-differentiated squamous cell carcinoma components.

Primary intraosseous carcinoma not otherwise specified (PIOC NOS) is a rare tumor assumed to arise from the epithelium, such as odontogenic cysts or benign tumors. Its clinical and imaging diagnoses are often challenging, especially in the early stages, as it mimics jaw cysts and benign tumors, and no specific findings have been identified. This report presents the case of a 66-year-old male patient with mandibular PIOC, highlighting the imaging findings over time.

N6-methyladenosine (m6A) is the most abundant epigenetic RNA modification in eukaryotes and plays a role in various cancers in humans. This m6A modification is regulated by m6A writers, erasers, and readers. One of the m6A erasers is α-ketoglutarate-dependent dioxygenase homolog 5 (ALKBH5).

Article Synopsis
  • The study focuses on the use of deep circumflex iliac artery (DCIA) flaps for reconstructing maxillary defects, aiming to improve surgical efficiency and outcomes through computer-assisted techniques.
  • Researchers reviewed 10 cases of maxillary reconstruction, noting various types of defects and documenting donor site choices, types of flaps used, and the success of surgical procedures.
  • Results indicated 9 successful recoveries with no complications, while one case required additional surgery due to necrosis, demonstrating the potential reliability of the DCIA flap method when combined with advanced technology.
