Abstract
It has long been known that pregnancy stimulates a variety of physiological mucosal changes, including pigmentary, elastic, and vascular changes. Pyogenic granuloma represents a vascular lesion observed during gravidism. We present three case reports of pregnancy tumor.
The patients ranged in age from 26 to 29 years old, and had lesions located on the tongue. In all cases, surgical excision was performed after delivery.
Histopathologically, pregnancy tumor is identical to pyogenic granuloma of unrelated etiology. The majority of lesions exhibit nodular inflammation hyperplasia and numerous small dilatated vascular channels and proliferating endothelial cells. The surface with a thin atrophic epithelium is almost completely ulcerated and coated with a thick, fibrinopurulent exudate. This “epidermal collarette” surrounds the deeper portion. There are three main pathological features: granulomatous, hemangiomatous, and intermediate types. One case was the hemangiomatous type and two cases were the intermediate type.
This article also discusses the clinical findings, pathology, therapy and prognosis of pyogenic granuloma.
