Myxoglobulosis of lower lip: Report of two cases

In this paper, we present two case reports of myxoglobulosis, in a 24-year-old female and a 40-year-old male patient who came to our hospital with a chief complaint of painless swelling of the lower lip of approximately 6 months duration. A study of two case reports has been given here. In these patients, histological examination of the surgically excised tissue was carried out. Histopathological examination showed an extravasation mucocele with the lumen exhibiting unique globular organizations of mucin surrounded by granulation tissue capsule and lacking an epithelial lining. Our two cases are possibly an analogue of myxoglobulosis, a rare variant of the appendical mucocele. Thus, though rare, the possibility of occurrence of myxoglobulosis in cystic lesions of the lip should be considered. The prognosis is regarded better as compared to the other types of mucoceles with low recurrence rate due to good host response and globular organizations of mucin. However, follow- up of these cases and more such cases is required to confirm the prognosis. The need for study of many such cases to confirm the etiology, pathogenesis and biologic nature of this variant is being felt.
