The authors present 3 exemplary entities which show paradigmatic clinico-pathological settings of infectious angiogenesis: Bacillary angiomatosis, orf (ecthyma contagiosum), and kaposi sarcoma [1]. Diagnoses other than ecthyma contagiosum were eliminated by punch Biopsy [2]. She subsequently developed a Generalized maculo-papular rash, which was initially thought to be an adverse drug reaction, but, on hindsight, may have been erythema multiforme associated with orf [3]. ecthyma contagiosum is a zoonotic disease caused by the parapoxvirus that causes "sore mouth" in sheep and goats and orf in human [4]. Negative-staining electron Microscopy (EM) is a fast and reliable diagnostic tool, but is not widely available [5].

Furthermore, it may be complicated by erythema multiforme, Stevens-Johnson syndrome, erysipelas, generalized mucocutaneous Eruption, toxic erythema, Eyelid Oedema and giant, Persistent or recurrent lesions in immunocompromised patients [6]. Proper information and reassurance of the infected patient are very important [7]. With the exception of ecthyma contagiosum (orf), similar small histiocytes were not found in other viral infections or in nonspecific ulcers of the skin [8]. In cases of herpetic folliculitis, small histiocytes showed massive epidermotropism towards Hair follicle epithelium [9]. The orf virus (responsible for ovine ecthyma contagiosum), however, has never been described as responsible for the profuse superinfection of an atopic eczema [10].
