Lobulated capillary haemangioma: a common lesion in an uncommon site

Abstract

SUMMARYPyogenic granuloma (PG) is a well-known localised granulation tissue overgrowth. It remains an aetiopathological enigma, with trauma, inflammatory and infectious agents being the suspected causative factors. It is a relatively common benign mucocutaneous lesion occurring intraorally or extraorally and is more common in women in the second decade of their lives than in men. Although it is a common lesion it may present with varying clinical features that sometimes may mimic more serious lesions such as malignancies. The clinical diagnosis of such lesion can be quite challenging. This case report drives attention towards the uncommon location of PG of lobular capillary haemangioma type occurring on anterior palate. Surgical excision of the lesion was planned because of the discomfort attributed to large size of the lesion and hindrance in mastication. BACKGROUND

A Case of Bilateral External Auditory Canal Pyogenic Granuloma in a Pregnant Woman

“…Ulcerative areas are also common; neutrophils may be detected near ulcerated surfaces. These findings are rather specific, making it easy to diagnose a pyogenic granuloma, but a hemangioma also features a lobular arrangement of capillaries; a pyogenic granuloma is thus sometimes misdiagnosed [ 14 ].…”

“…And the wound healing was uneventful. Recently reported treatment modalities for hemangiomas in the literature includes steroid therapy, electrosurgery, Nd:YAG laser, CO2 laser, cryosurgery, and sclerotherapy [11,12]. Nowadays, sclerotherapy is used largely because of its ability and efficiency to preserve the surrounding tissue [13].…”

Benign vascular lesions of the lips: Diagnostic approach

“…However, considering oral mucosa, pyogenic granulomas are more frequent in the gingiva . Pyogenic granulomas may also be classified as lobular capillary hemangioma or non‐lobular capillary hemangioma . This classification is based on its histological aspect, because it shows a high proliferation of endothelium and capillaries, frequently dilated blood vessels and they are often arranged in lobules.…”

“…In general, pyogenic granulomas do not offer any difficult in histologic diagnosis due to its unique aspect. Only when the lobular arrangement is prominent it can be mistaken as a hemangioma, especially if clinical history is not well‐documented . GLUT‐1 is useful in differentiating pyogenic granuloma from infantile hemangioma as it is negative in the former …”
