“…Characteristic histological features of SS include dense infiltration of neutrophils in the upper and mid dermis (sparing the epidermis), oedema in the superficial dermis, leukocytoclasia and endothelial swelling. Vasculitis is not a feature 9. A leukocytosis (neutrophilia) on serology is consistent with SS.…”

“…Although there may be some overlappings between EPC and APEX, EPC differs from APEX in its characteristics of male preponderance, average age at onset of 45 years, high relapse rate and unique annular configuration. Lichen striatus, cutaneous lupus erythematosus [11] and perniosis [13] often demonstrate perieccrine mononuclear cell infiltration, although the clinical manifestations differ from EPC. Interestingly, Fowler et al [14] reported that 10 of 26 subjects allergic to hexavalent chromium demonstrated perieccrine inflammation after immersion of the skin in a potassium chromate bath.…”

“…Most of the reported EPC cases were free of systemic diseases, though our 2 cases were accompanied by polymyositis and interstitial pneumonia or advanced gastric cancer. A variety of agents have been implicated in the etiology of EAC, including infection by bacteria, rickettsia or [11] . On the other hand, because of the histological characteristics of EPC, i.e.…”

“…Pain was an infrequent complaint. The histologic feature characteristic of the early stage of polyarteritis nodosa is neutrophilic infiltration with fibrinoid necrosis involving the muscle coat of medium-sized or small arteries, with more mononuclear cell involvement and fibrosis in the later stage 8,9 ( Table 5). In the biopsy specimens of the present patients with lymphocytic thrombophilic arteritis, arterioles in the deep dermis and superficial subcutis showed intense infiltration of lymphocytes and histiocytes in their muscular walls.…”

“…Histologically, lesions show luminal fibrin deposition and fibrin thrombi mainly affecting small dermal vessels, producing a segmental hyalinizing vasculopathy (Table 5). 8,9,11 Inflammatory infiltrate is often scant and consists mainly of lymphocytes perivascularly. Disturbances in coagulation or fibrinolysis have been found with increasing frequency in livedoid vasculitis, suggesting a prothrombotic state as the etiology.…”
