ABSTRACT
Cyst formation can occur in any location where lacrimal gland tissue is present. A new classification is proposed based on these locations: palpebral lobe cysts (simple dacryops); orbital lobe cysts; cysts of the accessory lacrimal glands of Krause and Wolfring; and cysts of ectopic (choristomatous) lacrimal glands. The characteristic clinical presentation, histopathology, and treatment of these lacrimal ductal cysts is described.

We report a 22-year-old male who underwent a left thoracostomy and left lower lobectomy for a shotgun wound of the left anterior chest. During surgery, two chest tubes were placed in the left hemithorax at the level of the first and second intervertebral spaces. On the 10th postoperative day, the patient developed a left-sided miosis and ptosis. The diagnosis of a left preganglionic Horner's syndrome was confirmed by pharmacologic testing. The Horner's syndrome was unchanged 3 months after discharge. We conclude that the chest tubes damaged the preganglionic sympathetic fibers of the left orbit resulting in this patient's Horner's syndrome.

Larval ascarid nematodes recently discovered in fresh salmon were identified as Anisakis larval Type I, this roundworm is the etiologic agent of anisakiasis, a parasitic disease characterized by eosinophilic granulomas affecting the human gastrointestinal tract. Infection may occur following ingestion of raw or poorly cooked fish. Patients generally present with an acute abdominal syndrome mimicking a wide variety of clinical conditions, thus creating a diagnostic dilemma. Unselected samples of fresh salmon tested by the University of Michigan Clinical Microbiology Laboratory and School of Public Health were all infected, the mean worm burden calculated as 79.3 larvae per kilogram of fish. The significance of this infection and the implications for morbidity in the United States are discussed.
