Abstract Details



Purpose:

To evaluate pathology of pterygia excised in shafa medical center

Setting:

Kerman University of Medical Sciences, Kerman- Iran

Methods:

In this cross-sectional study pathologic report of 111 cases of pterygia resected by a single surgeon from April 2011 to September 2012 were evaluated. The samples were examined for presence of any malignancy and other abnormal pathologies.

Results:

111 eyes of 111 patients were studied. The age of patients was 23-90 (56.5±16.6) years. The main symptoms were decreased vision(79.3%) and surface irritations(17.1%). In 105 (94.6%) the lesion was nasal, 1(0.9%) temporal and 5(4.5%) double (temporal and nasal). The width of pterygium at limbus was 4-9 (6.1±1.2)mm, the length of lesion on cornea was 2-7(3.9±1.2)mm. 67cases (60.4%) were operated(treated) by free or rotational cnjunctival flap and 46(39.6%) by bare sclera technique. In 6(5.4%)cases pathologies other than pterygium were reported. These cases were squamous cell carcinoma(SCC) in 3(2.7%) , carcinoma incitu in 2(1.8%) and ganglion cyst in 1(0.9%).Pathologic reports of remaining 105 cases were pterygium. 2 cases of SCC were more than 50 and 1 case less than50 years old. Both carcinoma insitu cases were less than 50 (p=0246). All three cases of SCC were male, one case of carcinoma insitu was male and the other one was female(p=0.226). 11 cases (9.9%) were atrophic (grade I), 75 (67.6%) intermediate (grade II) and 25(22.5%) fleshy (grade III).In atrophic group no malignancy was reported, in intermediate group there was 1 SCC and 2 carcinoma insitu and in fleshy group 2 SCC and 1 ganglion cyst (P=0.228).

Conclusions:

All excised pterygia must be studied for malignant transformations and coexistent malignancies. FINANCIAL INTEREST: NONE
