Angiolymphoid hyperplasia with eosinophilia of the auricle:
progression of histopathological changes.
J Laryngol Otol. 2006 May;120(5):411-3.
Angiolymphoid
hyperplasia with eosinophilia is a rare condition that demonstrates
dermal or subcutaneous proliferation of endothelial cells associated
with an inflammatory cell infiltrate. A case is reported, with
emphasis on the histopathological features on repeated biopsies. The
report serves to stress the importance of considering this condition
in the differential diagnosis of lesions in and around the ear.
Protruding
tumorous angiolymphoid hyperplasia with eosinophilia (ALHE) of the
scalp accompanied by arterial occlusion.J
Dermatol. 2002 Jan;29(1):38-42.
We report a
case of an extraordinarily large tumorous form of ALHE developing on
the occiput of a 57-year-old Japanese male. Histologically, it was
characterized by increased numbers of small blood vessels, fibrosis,
and lymph follicle formations with massive eosinopilia in the dermis
in addition to an occluded artery in the deep dermis.
Angiolymphoid
hyperplasia of the head and neck.J
Laryngol Otol. 1988 Jan;102(1):100-1.
Angiolymphoid hyperplasia is a rare benign condition affecting the
skin and subcutaneous tissue of the head and neck. Superficial (intradermal)
lesions frequently affect the external ear and such a case
presenting to an otolaryngologist is described. Clinically the
disease is characterized by single or multiple plum-coloured nodules
or plaques which are often itchy and may bleed with mild trauma.
Histologically the lesions are composed of proliferating capillary
vessels associated with a heavy inflammatory infiltrate including
eosinophils and mast cells. The cause remains obscure. The lesions
often persist for many years and may regress spontaneously. Several
forms of treatment have been used, including cryosurgery, curettage
and diathermy, radiotherapy and intralesional steroid injections. In
this case the Argon laser was employed. |
