Abstract

BACKGROUND:

In recent years, many new cutaneous vascular proliferations have been described. This is partly due to the current epidemic of AIDS, which has forced dermatopathologists to establish the diagnosis of the earliest patch-stage lesions of AIDS-related Kaposi's sarcoma and some of the recently described cutaneous vascular proliferations that may histopathologically mimic lesions of early Kaposi's sarcoma.

OBJECTIVE:

This article reports the clinical, histopathologic, and immunohistochemical findings in 6 cases of a clinicopathologic variant of cutaneous hemangioma, which we have named acquired elastotic hemangioma.

METHODS:

Six cases of acquired elastotic hemangioma were studied from clinical, histopathologic, and immunohistochemical standpoints. The histopathologic differential diagnosis with other similar cutaneous vascular proliferations is discussed.

RESULTS:

Acquired elastotic hemangioma appears on the sun-damaged skin of the dorsal aspect of the forearms or on the lateral aspects of the neck of middle-aged or elderly women. Clinically, lesions present as solitary erythematous plaques with variable morphology and in only some cases have a clearly angiomatous appearance. On histopathologic examination, acquired elastotic hemangioma is characterized by a band-like proliferation of capillary blood vessels involving the superficial dermis and arranged horizontally parallel to the epidermis.

CONCLUSION:

Acquired elastotic hemangioma is a distinctive clinicopathologic variant of hemangioma that should be differentiated from other cutaneous vascular proliferations. On histopathologic examination, it is characterized by capillary proliferation involving the dermis.
