Abstract
Purpose: :
To report the frequency of palpebral malignant tumors in a 15 year period.
Methods: :
This is a retrospective, transversal, observational and non–comparative study. All pathology reports from excisional biopsies of cases with palpebral malignant tumors from January 1990 to December 2004 were compiled. Files were divided according to demographic variables such as age and gender. Age distribution was categorized into 5 years intervals. Type of malignancy was divided according to histologic findings into epithelial, melanocytic, neural, vascular, lymphoproliferative or mesenchymatic.
Results: :
One hundred eighty cases were reviewed. Seventy male patients and one hundred and ten female. The number of biopsies made per year during the first five years were 7.6, from 1995 to 1999 were 11.6 and from 2000 to 2004 were 19.2. Basal cell carcinoma represented 69% of all cases: Nodular variety 103 cases (83.06%), more frequent in the age group between 76 and 80 years old, Morphea 10 cases (8.06%) between 51 and 55 and Adenoid 11 cases (8.88%) between 61 and 65, and 71 and 75. Squamous cell carcinoma 31 cases (17%) between 66 and 70. Sebaceous gland carcinoma 11 cases (6%) between 56 and 60. Melanoma 10 cases (6%) between 76 and 80. Non–Hodgkin Lymphoma 4 cases (2%) with heterogeneous distribution. Seventy percent of malignant palpebral tumors were seen between 56 and 80 years old.
Conclusions: :
The most frequent palpebral malignancies in our series are similar to the previously described, notwithstanding sebaceous gland carcinoma, melanoma and non–Hodgkin lymphoma overpass literature reports.
