A 13-year-old white girl with Crohn's colitis developed recurrent erythematous tender cords and nodules in the lower and upper extremities. Histologic examination of subcutaneous nodules of the right arm revealed granulomatous panarteritis of two muscular arteries in the subcutis. The patient's resected colon showed granulomatous transmural colitis without vasculitis. The association between Crohn's disease and cutaneous polyarteritis nodosa is reviewed and emphasis placed on histologic evaluation of suspicious subcutaneous nodules for correct diagnosis.

A case is presented of a patient, diagnosed preoperatively as having cecal carcinoma, who was found, at operation, to have a pathologically selective vasculitis involving the right side of the colon which was unclassifiable in any of the known vasculitides. Problems of diagnosis and classification and their bearing on management are discussed.

An 84-year old man was admitted to Mitoyo General Hospital because of progressive malaise and edematous erythema on both eyelids (Heliotrope erythema). He also noted blister on his neck as well as erythema on the extensor surface of finger joints (Gottron's sign), elbows and knees. Neither weakness nor pain of his proximal muscle was elicited on physical examination on admission. His blood test disclosed positive inflammatory signs (i.e., mild elevation of ESR and positive CRP) without elevated value of muscle enzymes. Electromyogram showed normal pattern. Infiltration of inflammatory cells was not revealed by histological examination of biopsied muscle. A diagnosis of 'amyopathic dermatomyositis' was made based on these observations. Computed tomography of his chest disclosed interstitial pneumonia spreading over both lower lung fields. Colon fiberscopy revealed a polyp in his descending colon, which was classified into group I on cytological examination. He was treated with two sets of methylprednisolone (mPSL) pulse therapy (500 mg/day, 3 consecutive days, intravenously) followed by 30 mg/day of oral prednisolone (PSL). His skin lesions responded well to the above treatment and the dose of oral PSL was tapered. One month after the initiation of treatment, severe stomatitis as well as a large ulcer beneath his tongue developed accompanying an intractable pain. Mucosal biopsy revealed necrotizing vasculitis in medium-sizedartery at the bottom of ulcer. Another set of mPSL pulse therapy brought a prompt relief of his symptom and prohibited the recurrence of oral lesion. It should be noted that our patient did not fulfill the diagnostic criteria for DM because of the lack of muscular symptoms whereas he had characteristic skin lesions. Regarding the frustration possibly encountered at the time of diagnosing amyopathic DM, both sensitivity and specificity of the skin lesion for the diagnosis of DM were investigated. Moreover, the rarity of blister as a skin manifestation of DM was discussed as well.

Isolated phlebitis of the gastrointestinal tract is rare and potentially life threatening. We report on a patient who developed peritonitis, requiring emergency laparotomy, total colectomy, and ileostomy because of colon necrosis. The specimen displayed multiple ulcerations and erosions. Histology showed a predominantly lymphocytic infiltrate of small-sized and middle-sized veins in the submucosa and subserosa, associated with granulomas and foci of vein wall necrosis. Arteries were spared. No local recurrence or systemic vasculitis developed during a follow-up period of two years. Isolated granulomatous phlebitis seems to be self-limited, and its cause is unknown. Surgical resection of the diseased intestine is usually curative.

We present a case of myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA)-associated vasculitis that demonstrated a systemic granulomatous lesion at autopsy. The patient initially showed anorexia, general malaise and anemia. Colon fiber was examined to detect the bleeding site, which revealed ischemic mucosal damage associated with venous fibrin thrombus. Because a high titer of MPO-ANCA was found, ANCA-associated vasculitis was suspected and the patient was started on steroid pulse therapy. However, anemia, renal failure and respiratory failure worsened and the patient died of sudden cardiac failure 2 days after the start of the therapy. An autopsy revealed systemic arteritis in multiple organs including the kidneys, liver, spleen, gastrointestinal system and genital organs that indicated fibrinoid necrosis accompanied by granulomatous reaction with multinucleated giant cells; the granulomatous reaction further extended along the splenic capsule. Glomerulonephritis and diffuse pulmonary damage, which are common in MPO-ANCA-associated vasculitis, were almost absent but parapleural fibrosis was present. The direct cause of death was presumed to be hemorrhagic shock due to rupture of an aneurysm in the gastric subserosa. As far as we know, this is the first case of a systemic granulomatous reaction in MPO-ANCA-positive vasculitis, although the cause of the granulomatous lesion is unknown.

We report the case of a 44-year-old white man who presented with progressively worsening crampy abdominal pain and distention. Deterioration of his clinical picture along with leukocytosis and radiographic evidence of severe colonic dilation rendered exploratory laparotomy necessary. Greatly distended and inflamed transverse and descending colon were evident and an extended left colectomy was performed. Characteristic changes of leukocytoclastic vasculitis in the serosal and muscular layers of the resected colon were demonstrated at histopathologic examination. Systemic leukocytoclastic vasculitis, usually coexisting with Henoch-Schonlein purpura, commonly affects the small bowel with clinical evidence of ischemia or bleeding. Colon involvement is infrequently reported in the context of systemic disease. Isolated colonic leukocytoclastic vasculitis without extraintestinal manifestations is rare. A previously unreported case of localized leukocytoclastic vasculitis of the left colon resulting in the impressive presentation of megacolon, without the presence of any precipitating factor or associated systemic disease is presented here, with an overview of the related literature.

The purpose of the investigation was to study the quantitative and qualitative composition of colon microflora in system connective tissue diseases and system vasculites. The authors studied colon microflora in patients with systemic lupus erythematosus, systemic scleroderma, nodular polyarteritis, and hemorrhagic vasculitis. The structure of symbiotic interrelations between microorganisms participating in the formation of colon microbiocenosis was determined. Colon microflora was found to be disordered in terms of its qualitative and quantitative composition. The predomination of anaerobic microorganisms was decreased, while the role of conditionally pathogenic bacteria was increased. The number of lactobacteria was significantly lowered; bifidobacteria and bacteroids were found frequently, while their number was substantially lowered as well. Conditionally pathogenic microorganisms and bacteria with hemolytic activity acquired high significance in the forming of the colon microbiocenosis of the patients. The frequency of the isolation and the density of colon colonization with staphylococci and conditionally pathogenic enterobacteria were significantly increased. General trends and peculiarities of changes in the quantitative and qualitative composition of colon microflora in some rheumatic diseases were determined. The data on the peculiarities of the colon microbiocenosis in these patients may be used to substantiate methods of complex therapy including correction of dysbiotic disturbances.

Behcet disease (BD) is a chronic, multisystem, inflammatory disease characterized by variable clinical manifestations involving systemic vasculitis of both the small and large blood vessels. The majority of BD patients present with recurrent oral ulcers in combination with other manifestations of the disease, including genital ulcers, skin lesions, arthritis, uveitis, thrombophlebitis, gastrointestinal or central nervous system involvement. Gastrointestinal BD occurs in 3 to 25% of the BD patients and shares many clinical characteristics with inflammatory bowel disease (IBD). Consequently, the differentiation between IBD and gastrointestinal manifestation of BD is very difficult. Intestinal BD should be considered in patients who present with abdominal pain, diarrhea, weight loss, and rectal bleeding who are susceptible or at a risk for intestinal BD.
