Abstract

Pyogenic granuloma (PG) is one of the most prevalent tumor-like lesions in the mouth, with two distinct histological variants: Non-Lobular Capillary Hemangioma (NLCH) and Lobular Capillary Hemangioma (LCH). This study aims to evaluate and compare the immunohistochemical expression of Ki-67 (proliferative activity) and CD 105 (angiogenic activity) in both types to find the conflict between the two.

Data from clinical information and microscopic findings were collected. The selection criteria, including sufficient tissue, minor bleeding and/or inflammation, and proper fixation, were used to examine 24 cases of PG (10 LCH, 14 NLCH) that performed hematoxylin and eosin (H&E) staining and immunostaining of anti-Ki-67 antibodies and anti-CD105 antibodies.

Our study showed female predilection, as 66.7% of cases were female (10 cases in LCH and 6 cases in NLCH). The mean patient age was 32.71%±15.35 years. LCH type of PG showed moderate positive expression of Ki-67 in 9 cases (64.3%); only two cases (14.3%) had a negative expression, while in 6 cases (60%) of NLCH, mild positive expression was seen, and in 4 cases (40%) it was moderate. The average number of blood vessels measured in LCH and NLCH samples treated with the anti-CD105 antibody was (72.7857±39.21479) and (47.1600±30.02855) respectively, with no significant difference between the two types of PG for both markers.

The results of the present study confirm that there are no differences between the LCH and NLCH types of PG in proliferative rate and angiogenesis activity, so both types seem to have the same biological behavior.
