Abstract

BACKGROUND:

Infantile hemangiomas have a characteristic natural history of rapid proliferation in the first weeks of life followed by spontaneous involution. At birth, they may be present as a precursor lesion. Sometimes one may see precursor lesions that never undergo a growth phase or that undergo minimal growth. It is unclear the exact nature of these precursor-like lesions.

OBJECTIVE:

We sought to describe the morphology and histopathology of these precursor-like lesions.

METHODS:

We describe 4 patients with macules resembling precursor lesions of hemangiomas that did not show proliferation phase or minimal growth. The histopathologic and immunohistochemical study with glucose transporter-1 was performed in all of these cases.

RESULTS:

The skin biopsy specimen showed superficial ectatic vessels that reacted with anti-glucose transporter-1 antibodies. All skin biopsy specimens exhibited capillary lobules in papillary dermis and, in two of them, in the reticular dermis and subcutis.

LIMITATIONS:

This text is limited by the number of cases reported.

CONCLUSIONS:

Precursor lesions of hemangioma that do not show proliferation phase or minimal growth represent, in the view of glucose transporter-1 immunoreactivity, true hemangiomas of infancy with an aborted or arrested growth cycle.
