Mucoepidermoid carcinoma of the lacrimal gland. Case report and review of the literature.
A 12-year-old girl was diagnosed as having mucoepidermoid carcinoma of the lacrimal gland. To our knowledge, only 14 cases of mucoepidermoid carcinoma of the lacrimal gland have been reported in the literature; this is the first case occurring in a child. Clinically, this tumor presented as a painless proptosis with inferonasal displacement of the globe. Histologically, it showed infiltrating lobules of neoplastic cells consisting of epidermoid cells admixed with mucin-containing cells and a mild lymphocytic infiltration in the stroma. The mucous cells stained positively with periodic acid-Schiff, Alcian blue, and mucicarmine dyes, but resisted digestion with hyaluronidase. This case illustrates that one should not exclude any diagnostic possibility just because the patient does not seem to belong to the appropriate age group.
The use of tarsus as a free autogenous graft in eyelid surgery.
This is a report of the use of autogenous tarsus as a free graft in 121 eyelid surgical procedures. Seventy-three operations were for reconstruction of full-thickness defects and 30 were for repair of eyelid retraction. The remainder were for repair of cicatricial entropion, symblepharon, distichiasis, and irregularity of the eyelid margin. No grafts failed. There were three complications to a donor eyelid. It is believed that donor eyelid complications are less likely when the graft is harvested so as to include the upper tarsal margin. The free autogenous tarsal graft was found to be effective in repairing a variety of eyelid defects.
The use of homologous tarsus as a donor graft in lid surgery.
Several materials have been used to extend the posterior lamella of the eyelids in cases of retraction due to thyroid disease, cicatrix, or loss of tissue. Substances previously used have been autogenous tarsus, mucous membrane, ear or nasal cartilage, and donor sclera or just space. I present the use of homologous bank tarsus, its advantages, limitations, and methods of handling.
Local injection of steroids for juvenile hemangiomas which disturb the visual axis.
Steroids have been used sine 1967 for the treatment of hemangiomas and for orbital hemangiomas since 1970. These were systemically administered which caused concern because of the possible systemic side effects. In 1979. Kushner described local injection of steroids in the eyelid of infants where an hemangioma obstructed the visual axis or refractive error was induced by pressure from the lesion. Five cases of lid hemangioma were treated using this method with varying degrees of success (possibly depending on percentage of mix of the tumor, capillary vs. cavernous). There were no measurable deleterious effects from the injections after a two-year follow-up.
Split-level full-thickness eyelid graft.
A new method of surgical treatment for cicatricial eyelid retraction involves grafts placed in both the anterior and posterior lamellae of the upper eyelid, when there is a shortage of tissue in both layers, caused by previous surgical procedures. The anterior lamellar graft is of postauricular skin and the posterior graft is of buccal mucosa. The two grafts are placed at different levels in the eyelid so that each has a viable vascular bed. The procedure, called the split-level full-thickness eyelid graft, is not designed to correct problems involving only the eyelid retractors, such as retraction secondary to thyroid disease.
