Eruptive xanthoma with unexpected granuloma annulare-like microscopic appearance: case report.
Eruptive xanthoma with unexpected granuloma annulare-like microscopic appearance - Case report Abstract: Eruptive xanthoma and granuloma annulare are dermatological diseases with different clinical findings that, sometimes, exhibit histopathological similarities with potential for misinterpretation. We report a case of an eruption of yellow-orange papules with erythematous borders in a 34-year-old male with high levels of serum triglycerides and cholesterol. ⋯ Review of the histologic material revealed eruptive xanthoma. Remission of the eruption after treatment of dyslipidemia confirmed the diagnosis of the eruptive xanthoma and motivated research about the histological similarities and differences between these diseases.

We report a case of an inflammatory variant of epidermolysis bullosa acquisita in a 53-year-old male, with itching blistering eruption on the trunk, armpits and limbs for six months. The skin biopsy specimen showed subepidermal blister with neutrophils. ⋯ Improvement of the blisters followed treatment with systemic corticotherapy and some lesions healed with milia. This is a rare presentation of epidermolysis bullosa acquisita, with inflammatory lesions at first.

We report a case of telangiectasia macularis eruptiva perstans in an 18-year-old male patient who developed multiple erythematous maculae on the trunk and limbs. Darier's sign was positive. Histopathology revealed mononuclear cell infiltrate and increased number of mast cells identified with Giemsa staining. Telangiectasiamacularis eruptiva perstans should be considered in patients with telangiectatic lesions of atypical appearance or distribution which start in childhood.
