Extragingival pyogenic granuloma histologically mimicking capillary hemangioma

The Use of Diode Laser for the Surgical Removal of Pyogenic Granuloma of the Dorsum of the Tongue: A Case Report

Pyogenic granuloma (PG) is a common reactive oral lesion predominantly involving the gingiva and rarely occurring on the dorsum of the tongue. It can develop at any age but more commonly in the second decade with a female predilection. Numerous factors are associated with its development, and surgical removal is the standard treatment. Various surgical modalities have been used to excise it. Herein, we report a case of a female patient in her late 60s who presented with an exophytic lesion involving the dorsum of the tongue, which was excised using a 940 nm diode laser. In addition, it discusses the advantages of diode laser as a surgical modality and describes this lesion's clinical features and pathogenesis.

Pyogenic Granuloma of the Retina: A Case Series

Aim

To describe the clinicopathologic features of pyogenic granuloma (granulation tissue proliferation) extending from the retina.

Methods

We describe 3 patients who underwent enucleation for endophthalmitis. The eyes were processed routinely for histopathologic examination.

Results

All 3 enucleated eyes contained granulation tissue with reactive vascular channels and intervening stroma infiltrated with inflammatory cells. The vascular channels were arranged in a fan-like configuration and the tissue was classified as representing pyogenic granulomas.

Conclusions

Pyogenic granulomas (granulation tissue) may emanate from the retina in cases of endophthalmitis. This is distinct from neovascularization that may occur in proliferative diabetic retinopathy, central retinal vein occlusion, or other etiologies.
