[Understanding microcapillary angioma, observations in pregnant patients and in females treated with hormonal contraceptives].

We report on histological findings in 3 female patients, who developed microcapillary angiomas either during pregnancy or upon changing the oral contraceptive. These hemangiomas consisted of small, well-differentiated vessels located in the reticular dermis only and did not show any intra- or extravascular cell proliferation. We discuss the possible etiological factors of these microcapillary angiomas as well as the question of their correlation with pregnancy or hormonal contraceptives.
