Mucoceles of the paranasal sinuses are expansile, benign mucus filled epithelial lined cystic-like lesion resulting from chronic obstruction to sinus ostia. They erode bony walls by pressure and resorption with frontal ethmoid predominately affected. The expansile can involve surrounding structures like orbit, intracranium or nasopharynx. Diagnosis is based on history, examination radiological ...

The orbitofrontal fibrous dysplasia is a rare, non-malignant disease that involves the development and thickening of craniofacial bones, causing facial asymmetry, visual, neurological and dental complications. Decreased visual acuity in orbitofrontal and sphenoidal fibrous dysplasia appears as a result of compressive lesions on the optic nerve. The aim of this article is to present the ophthalm...

INTRODUCTION Appendiceal mucoceles encompass neoplastic and non-neoplastic causes of a distended Appendix filled with mucus. Appendectomy is recommended when an appendiceal mucocele is identified, incidentally or otherwise, in the event it is secondary to a malignancy. For an intact mucocele, it is critically important to avoid rupturing the mucocele during resection, as rupture of a neoplastic...

OBJECTIVES/HYPOTHESIS To describe clinical characteristics of oral mucoceles/ranulas, with a focus on human immunodeficiency virus (HIV)-related salivary gland diseases. STUDY DESIGN A descriptive and clinical study, with review of patient data. MATERIAL AND METHODS We reviewed 113 referred cases of oral mucocele. The following anatomical sites were identified: lip, tongue, and floor of the...

BACKGROUND Salivary mucocele is an accumulation of saliva in a single or multiloculated cavity lined by connective tissue that is contiguous to a salivary gland-duct complex and is the most common condition affecting the salivary glands in dogs. Occasionally, different types of metaplastic lesions, such as squamous and osseous metaplasia - which are rare lesions in animals - can be observed in ...
