Primary mucinous adenocarcinoma of the eyelid.

Primary mucinous adenocarcinoma of the eyelid is a very rare tumor arising from the eccrine sweat gland. It is locally invasive with a high rate of recurrence following removal. Although uncommon, metastasis to regional lymph nodes does occur, and there have been several reports of more distant metastasis. This tumor is characterized by the secretion of mucin. This mucin usually forms into pools surrounding the clusters of tumor cells. Less commonly, the mucin may collect within the tumor cells and not be secreted into the extracellular spaces. Such a "mucin-poor" form of the tumor involving the eyelid was recently seen and is reported here. The clinical and pathologic characteristics of primary mucinous adenocarcinoma are presented and the modes of treatment are discussed.

Pseudonasolacrimal duct obstruction caused by nasal allergy.

While mechanical obstruction of the nasolacrimal duct is the most common cause of acquired unilateral epiphora, it is not the only one. Of the 94 patients evaluated with this symptom, 22 cases (23%) were caused by primary nasal changes in the form of nasal allergy. Many of the characteristic findings of mechanical obstruction were present. Several patients had previous nasolacrimal duct surgery, which failed to eliminate the epiphora. Nasal allergy was not initially considered either by previous examiners or the patients themselves, because of the absence of typical allergic symptoms. All of these patients, however, obtained relief from their unilateral tearing with treatment directed toward the nasal pathology only. Oral sympathomimetics and antihistamines were the most effective. Two patients improved with primary nasal surgery.

Amblyopia.

Amblyopia, commonly known as "lazy eye," is a frequent but preventable cause of decreased vision. An anatomically normal eye, free from organic disease, has reduced vision compared with the other eye. Ptosis of the eyelids, strabismus, certain refractive disorders and other abnormalities may precede amblyopia. If discovered early enough, usually before the age of five, amblyopia can often be reversed.
