Established lesions comprise of well-developed, flattened, endothelium-lined capillary channels of varying sizes in a lobular configuration.

Toro A, Mahfouz AE, Ardiri A, Malaguarnera M, Malaguarnera G, Loria F, Bertino G, Di Carlo I. If deeper orbital extension is suspected, then CT or MRI may be used. Pyogenic granuloma easily bleeds with minor trauma. Cysts that are within the solid nodule, or have peripheral enhancement, are presumably part of the tumor and should, therefore, be resected. When lesions are larger than 5 cm, some heterogeneity may be demonstrated. Pyogenic granuloma Recurrence is common, especially for gingival lesions, after inadequate treatment or persistent aetiological factors. In symptomatic patients or those with hemangiomas large enough, causing mass effect, surgical resection should be considered after other causes of pain have been excluded. Hence, the management of capillary hemangiomas depends on the location and whether the lesion causes visual impairment.
