Lichen sclerosus is a chronic inflammatory disease, usually located in the genital area. The etiology of lichen sclerosus is multifactorial, with participation of genetic, autoimmune, infectious and hormonal factors. Bullous clinical form stems from hydropic degeneration of the basal membrane, constituting a less frequent variant of the disease. In this work, we report the case of a female patient, 55 years old, who in the last three years presented whitish plaques, with horny spikes, located on back and arms. Some of these lesions evolved with hemorrhagic blisters, which after histopathological examination confirmed the diagnosis of bullous and hemorrhagic lichen sclerosus. The patient was treated with high-potency topical corticosteroid for two months, resulting in remission of bullous and hemorrhagic lesions.

Granuloma faciale is a rare dermatosis of chronic course, benign, usually asymptomatic, first described in 1945 by Wingley. It is characterized by the appearance of well-defined, single or multiple papules, plaques and nodules, predominantly located in sun-exposed areas, especially the face. In this work we report the case of a female patient, 58 years old, evolving for ten years with multiple erythematous-brownish and asymptomatic papules on the face, whose histological examination confirmed the diagnosis of granuloma faciale. The patient was treated with topical tacrolimus, evolving with regression of lesions.

The livedoid vasculopathy is an obstructive vascular process of etiology not yet fully known, being possibly associated with several prothrombotic events. It is clinically characterized by the presence of painful and recurring purpuric lesions, which usually suffer ulceration and evolve with formation of white atrophic scars usually located in the lower limbs. Two cases are here reported of painful ulcerated lesions on the lower limbs, in which the identification of VL enabled the diagnosis of systemic diseases.
