Acquired Capillary Haemangioma of Eyelid
Solitary acquired haemangioma of the eyelid appear as distinct red to red-blue papule ranging in size from about 0.5 mm to 5 mm in size.
Patient may present with bleeding haemangioma following trauma.
The acquired capillary haemangioma looks similar to mature type of congenital capillary haemangioma.
Hormonal changes during puberty and pregnancy may cause the development of vascular lesions. Trauma and irritative agents may act as inciting factors for production of capillary haemangioma.
Clinically, solitary acquired capillary haemangioma of eyelid may present as a red to red-blue papule which may range from 0.5 to 5 mm in size. Smaller lesions are red in colour and the larger ones give a bluish appearance. These may become pedunculated with cherry-like surface irregularity, hence the name cherry haemangioma. It generally moves with the skin. Localised haemangiomas are usually very compressible. It may bleed following trauma.
Pathology
Histopathologically, in early stages, acquired capillary haemangioma is similar to congenital capillary haemangioma. It shows newly formed capillaries with narrow lumina and prominent endothelial cells arranged in lobular fashion.
In fully matured lesion, the vascular lumen is dilated, the endothelial cells more flattened, and the stroma is oedematous and hyalinised. In acquired capillary haemangioma, there is less capillary proliferation as compared to a similar condition called pyogenic granuloma.
Differential diagnosis
Pyogenic granuloma: Some authorities consider acquired capillary haemangioma to be closely related to pyogenic granuloma. But pyogenic granuloma shows more endothelial proliferation than capillary haemangioma. The term capillary haemangioma of the pyogenic granuloma type is applied to this lesion.
Angiosarcoma
Cavernous haemangioma
Eyelid varix
Most acquired capillary haemangiomas are just observed over time, since they are generally small and have no malignant potential.
Surgical therapy
Complete excision of the larger haemangiomas may be resorted to for cosmetic reasons. Electrodissection, cryotherapy or radioablation may be done to destroy the growth.
Prognosis is usually good.
