Neurofibromas of the eyelid are a well-recognized manifestation of neurofibromatosis. Several different presentations have been described. The authors present a case of a 52-year-old man with an unusual eyelid neurofibroma that presented as sudden vision loss from obstruction secondary to prolapse of the palpebral conjunctiva.

Aim: While most splenic ruptures manifest as immediate hemorrhage, a minority of patients experience delayed rupture, which occurs days to weeks after the initial trauma. Although there have been reports of delayed splenic rupture following trauma, the exact pathophysiology of this condition and the appropriate treatment remain contentious. This article aims to further discuss and summarize the diagnosis and treatment protocols for delayed traumatic rupture of the spleen through the collection and analysis of existing clinical data, combined with previous literature.

Background: Central nervous system (CNS) involvement in diffuse large B-cell lymphoma (DLBCL) is relatively rare, occurring at a rate of approximately 5%. Primary CNS lymphoma (CNS-DLBCL), a subtype of DLBCL, is rare clinically but highly malignant and invasive. Its atypical clinical symptoms and imaging features contribute to a high rate of misdiagnosis and a poor prognosis.

Great apes have maintained a stable karyotype with few large-scale rearrangements; in contrast, gibbons have undergone a high rate of chromosomal rearrangements coincident with rapid centromere turnover. Here, we characterize fully assembled centromeres in the eastern hoolock gibbon, Hoolock leuconedys (HLE), finding a diverse group of transposable elements (TEs) that differ from the canonical alpha-satellites found across centromeres of other apes. We find that HLE centromeres contain a CpG methylation centromere dip region, providing evidence that this epigenetic feature is conserved in the absence of satellite arrays.

Background: Over the past two decades, an increased understanding of molecular alterations has greatly refined salivary gland tumor classification. Many tumors that were previously difficult or impossible to classify have been recognized to represent emerging entities based on shared histologic, immunophenotypic and molecular characteristics. While initial attention was given to carcinomas, more recently molecular discoveries have shed light on salivary gland adenomas as well.

Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, University of the Western Cape and National Health Laboratory Service, Tygerberg Hospital, Cape Town, South Africa.
Background: Langerhans cell histiocytosis (LCH) rarely presents in the oral and maxillofacial region, and while isolated and small collections of Langerhans-type cells have been found in periapical cysts, there have been no reported cases of LCH arising in periapical cysts.
Methods: A 58-year-old female presented with isolated erythematous dry skin lesions and a radiolucent lesion of the anterior maxilla. Microscopic examination of the enucleation specimen revealed a periapical cyst with large collections of atypical cells with grooved folded nuclei with eosinophils consistent with LCH.
