4 HISTOPATHOLOGY

Nail histopathology.

The structure of the nail unit is complex and many dermatologists and dermatopathologists have an incomplete understanding of it. Familiarity with the anatomy and histology of this unit, however, is a key factor in improving the diagnostic yield of nail biopsy. Inflammatory or infectious conditions that affect the nail can have a marked impact on a patient's quality of life. A wide-ranging vari...

Molecular-Friendly Histopathology

The rapidly expanding fields of pharmacogenomics and pharmacodiagnostics have presented the pathology laboratories with many challenges and opportunities. As custodians of patient tissues, these laboratories are in the logical position to perform biomolecular testing for proper management of patients. In order to meet these challenges, the pathology laboratories of the twenty-first century shou...

Methods. Forty-four surgically excised melanocytic lesions of the iris were histologically classified as nevus or melanoma. Morphometric analysis using a digital filar micrometer (LaSICO 1602N-10 and 5-4A) measured the mean size of the 10 largest nucleoli, and Feulgen staining and image cytometry (CAS 200 Cell Analysis Systems) analyzed the nuclear DNA ploidy in the lesions. Patient follow-up i...

Histopathology of radial keratotomy.

Report of a Case. A 39-year-old man with a history of RK performed elsewhere 8 years prior had complaints of decreased vision in both eyes. The patient’s preoperative refraction was –9.25 OD and –9.50 OS. According to the patient, the initial surgery was uncomplicated, although both eyes required enhancements. Cycloplegic refraction in our office was –3.50 +0.50 70 OD and –13.50 +1.00 100 OS, g...
