Primary mucinous carcinoma in a 54-year-old man.

Primary mucinous carcinoma is a rare malignant tumor that most frequently occurs in the periorbital area. This tumor originates from the deepest portion of the eccrine sweat duct. This normally asymptomatic and slow-growing tumor has demonstrated a local recurrence rate of 30% after excision with narrow surgical margins and can have local metastases.

Congenital and acquired blepharoptosis.

Blepharoptosis is a relatively common condition that is frequently encountered by the ophthalmic surgeon. Treatment remains somewhat unpredictable, and the choice of one of the various surgical options depends on the cause of the ptosis and the amount of levator function. Recent contributions to the literature on the classification and management of ptosis are reviewed here.

Tearing: lacrimal obstructions.

Tearing disorders are relatively common. Comprehensive consideration of the entire tearing system can assist the diagnosis and treatment of tearing problems to improve, if not cure, the condition. The general symptom complaint of "tearing or a feeling of wetness/irritation" most commonly relates to a dry or irritated eye, which usually responds well to medical therapy or punctal occlusion.

DNA flow cytometry of sebaceous cell carcinomas of the ocular adnexa: introduction to the technique in the evaluation of periocular tumors.

DNA content abnormalities are well recognized in tumor cell biology and kinetics. We introduce the technique of DNA flow cytometry through the study of the sebaceous cell carcinomas of the ocular adnexa. By correlating the data to the standard histopathologic parameters of pagetoid changes, degree of anaplasia, and stromal inflammation, significant associations are revealed.

An analysis of thirty cases of orbital lymphangioma. Pathophysiologic considerations and management recommendations.

Thirty cases of orbital lymphangioma were reviewed. Clinical, imaging, and microscopic findings were integrated to develop a pathophysiologic construct and management guidelines. The basic lesion might be considered an abortive vascular system which arborizes among normal structures.
