ReviewCutaneous vascular proliferation. Part II. Hyperplasias and benign neoplasms.
This second part of our review about vascular proliferations summarizes the clinicopathologic features of the cutaneous vascular hyperplasias and benign neoplasms. Hyperplasias comprise a heterogeneous group of vascular proliferations that eventually show a tendency to regression. Angiolymphoid hyperplasia with eosinophilia is included within the group of hyperplasias because of its historical denomination and its reactive nature, probably as a consequence of an arteriovenous shunt, although usually the lesions do not regress. ⋯ For these reasons, we classified hemangiomas into superficial and deep categories. Some of the lesions reviewed have been recently described in the literature, and they may histopathologically mimic lesions of Kaposi's sarcoma; these include targetoid hemosiderotic hemangioma, microvenular hemangioma, tufted hemangioma, glomeruloid hemangioma, kaposiform hemangioendothelioma, spindle-cell hemangioendothelioma, and benign lymphangioendothelioma. In each of these lesions, we update and emphasize those clinical and histopathologic features that are helpful for differential diagnosis with lesions of authentic Kaposi's sarcoma in any of its three stages of development (patch, plaque, or nodule).

Randomized Controlled Trial Multicenter Study Clinical TrialEffectiveness of norgestimate and ethinyl estradiol in treating moderate acne vulgaris.
An excess of androgen is believed to contribute to development of acne in some patients. Because oral contraceptives (OCs) may reduce the active androgen level, hormonal therapy with OCs has been used successfully to treat patients with acne, although this treatment has previously not been studied in placebo-controlled trials. ⋯ An OC containing 0.035 mg of ethinyl estradiol combined with the triphasic regimen of norgestimate is a safe and effective treatment of moderate acne vulgaris in women with no known contraindication to OC therapy.

Case ReportsTarget lesions on the lips: childhood herpes simplex associated with erythema multiforme mimics Stevens-Johnson syndrome.
Erythema multiforme and Stevens-Johnson syndrome are both characterized by areas of epithelial necrosis. An important clinical feature that distinguishes the two is the extensive mucosal necrosis in Stevens-Johnson syndrome but not in erythema multiforme. ⋯ We describe three boys with herpes simplex virus-associated erythema multiforme who had severe necrosis of the lips develop and were initially diagnosed with Stevens-Johnson syndrome. The lip lesions were large target lesions of erythema multiforme rather than the extensive necrosis seen in Stevens-Johnson syndrome and all three had a benign course.
