The clinical and histopathologic findings in 13 patients with lipomembranous changes in the subcutaneous adipose tissue as part of the inflammatory reaction are presented. Nine patients had clinical evidence of vascular disease and four had clinical evidence of connective tissue disease. Histopathologic evidence of endarteritis obliterans, venous stasis, and hemorrhage was present in more than half the patients, and the clinical lesion of liposclerosis was frequently present. These findings suggest that the histologic changes of lipomembranous panniculitis may be the result of an inflammatory reaction in patients who have the liposclerosis of venous insufficiency with connective tissue disease or previous leg ischemia or both.

A 70-year-old patient with a 6 x 6 x 12 cm mass involving the mesentery root is discussed. The pseudotumorous infiltration was detected by ultrasound done because of nonspecific abdominal symptoms and weight loss. Laparoscopic biopsy confirmed the diagnosis of mesenteric panniculitis. The primary histologic criterion is infiltration of the mesenterium by foamy lipid-laden macrophages, clusters of lymphocytes and fibrosis. The majority of cases follow a benign course and need no therapy, but co-existence of lymphoma has been reported. There have been few cases where panniculitis with progressive fibrosis changed into retractile mesenteritis with shortening of the mesenterium and compression of mesenteric vessels with partial or complete intestinal obstruction or ischemia requiring surgery. Few reported cases of severe and progressive disease have been treated with prednisone and azathioprine or cyclophosphamide.

A 33-year-old men presented with systemic sclerosis accompanied by both unusual panniculitis and overlying discoid lupus erythematosus (DLE)-like skin changes on the left buttock. The lesion did not completely match either lupus erythematosus profundus or morphea profunda but featured clinical and pathological findings halfway between the two entities. No case report of co-existence of systemic sclerosis and morphea profunda was found in the literature, but there are three case reports of patients with systemic sclerosis and lupus erythematosus profundus. One of the three cases had DLE-like changes on the surface of the lesion, a clinical picture similar to our case. We speculated that the DLE-like changes in the overlying skin were due to local tissue ischemia. The accompanying panniculitis in our case was considered to be unique and somehow different from morphea profunda or lupus erythematosus profundus.

Cutaneous mucinosis secondary to autoimmune collagen vascular disease is well recognized, but manifestation as cellulitis-like massive cutaneous mucinosis preceding dermatomyositis is unusual. Here we report a 21-year-old Taiwanese woman with a large, rapid onset, painful erythematous, edematous plaque, which histopathologically revealed septal panniculitis with fat necrosis and massive mucin deposition. Incapacitated muscle weakness of proximal extremities, generalized edema, heliotrope erythema, and Gottron's papules developed in a short period of time with high titers of serum muscle enzyme. Serological titers of ANA, anti-dsDNA, anti-ENA panels, and erythrocyte sedimentation rate, however, all showed unremarkable results. Diagnosis of dermatomyositis was confirmed by electromyographic findings of myopathy. As the disease progressed, large, deep cutaneous ulceration and vesiculobullous lesions also developed. In spite of aggressive treatment, the patient died 9 months after the disease onset, probably due to the complication of gastrointestinal ischemia and perforation.

Mesenteric panniculitis also named retractile mesenterite is a rare tumor-like lesion that thickens and shortens the mesentery. It is characterized by the association of inflammation, necrosis or fibrosis involving the adipose tissue of the bowel mesentery. The pathophysiology of this disease remains unclear despite associations with inflammatory diseases or malignancies, especially lymphomas that have been described. When symptomatic, patients may present with abdominal pain, palpable abdominal mass or intestinal obstruction. The disease remains asymptomatic in 30 to 50% of cases. Abdominal CT plays an important role in suggesting the diagnosis and can be useful in distinguishing the several conditions that can mimic mesenteric panniculitis. Nevertheless, pathologic examination of surgical excisional biopsies or sometimes percutaneous biopsies remains necessary to confirm the diagnosis and exclude an underlying infection or malignancy. Medical treatment may consist of therapy with anti inflammatory or immunosuppressive agents and can be proposed in highly symptomatic diseases. Surgical treatment should be exclusively attempted when intestinal obstruction or ischemia occur. Most of the time, it consists in intestinal derivation or segmental resection because complete excision of the lesions is often not possible. Mesenteric panniculitis usually has an uneventful clinical course and resolves spontaneously in a variable delay.

Systemic sclerosis (SSc) is an autoimmune systemic disease characterized by small vessel involvement that leads to tissue ischemia and fibroblast stimulation resulting in accumulation of collagen (fibrosis) in the skin and internal organs. Lipomembranous panniculitis is a peculiar type of fat necrosis and has been reported with clinical conditions, commonly with peripheral vascular diseases. We describe a case of a 43-year-old woman with SSc manifestations, who presented with black scaly skin plaques, associated with thickening of the subcutaneous fat tissue, on the lateral surface of her thighs, her calves, gluteal area and lower abdomen. Biopsy revealed lipomembranous panniculitis. Lipomembranous changes have been seen in connective tissue disorders such as lupus profundus, morphea, systemic sclerosis and panniculitis associated with dermatomyositis, but rarely in thighs, calves, gluteal area and lower abdomen.

Inferior mesenteric venous thrombosis (IMVT) is a very rare disease of colon ischemia. We experienced two cases of IMVT that required operations. The first patient was a 74-year-old male, who was admitted to our hospital because of melena and diarrhea. He was diagnosed with IMVT by angiography. As no improvement was seen after the conservative therapy for a month, left colectomy and transverse colostomy were performed. There was a small ulcer in the resected colon mucosa. The findings of histopathological examination revealed that mild and repeated ischemia of the colon had been caused. The second patient was a 70-year-old male, who was admitted to our hospital with the chief complaint of constipation, lower abdominal pain and nausea. He was diagnosed as IMVT by angiography. As no improvement was seen after the conservative therapy for a month, an operation was performed. The operative findings confirmed severe swelling of mesenteric fatty tissue and vascular ectasia of mesocolon. Left colectomy and transverse colostomy were performed. Histopathological examination of surgical specimens disclosed the multiple thrombi and almost complete occlusion of the inferior mesenteric vein, the invasion of lipid-filled macrophages as mesenteric panniculitis, and ischemic change in the sigmoid colon mucosa.

Calciphylaxis is an infrequent but severe entity found in chronic dialysis patients. Its clinical pattern consists of tissue ischemia with itchy and painful subcutaneous nodules and plaques, most often located on the abdomen, buttocks, thighs and/or legs. These injuries evolve to extensive superficial necrosis of the skin overlying the panniculitis, with ulceration, overinfection and consequent sepsis. Current treatment modalities used to counteract this pathology are not entirely effective. A new treatment reported for calciphylaxis, is the use of intravenous sodium thiosulfate. This inorganic salt is already used in the treatment of intoxication caused by cyanide, in patients with calcific nephrolithiasis and tumoral calcinosis, with very good and safe results. We herewith report a case of calciphylaxis that was cured using intravenous sodium thiosulphate treatment.

Sclerosing mesenteritis is a rare inflammatory disease of the bowel mesentery. It produces tumor-like masses of the mesentery composed of varying degrees of fibrosis, chronic inflammation, and fat necrosis. It has been described variously as fibrosing mesenteritis, retractile mesenteritis, mesenteric Weber Christian disease, and systemic nodular panniculitis. The etiology and pathogenesis of the disease are as yet unknown, but autoimmune disorder, previous abdominal surgery, trauma, and ischemia could play a role. The clinical features include abdominal pain, vomiting, diarrhea, and constipation. Occasionally, patients with this condition may present with bowel obstruction. Rarely, It can be associated with other idiopathic inflammatory disorders such as retroperitoneal fibrosis, sclerosing cholangitis, and orbital pseudotumors. We report a case of idiopathic sclerosing mesenteritis with retroperitoneal fibrosis in a 58-year-old man.

Mesenteric panniculitis is a rare, benign disease characterized by a chronic non-specific inflammatory process of mesenteric fat tissue with unknown etiology. The small bowel mesentery is affected mostly. This process rarely involves the large intestine mesentery. Mesenteric panniculitis includes symptoms as abdominal pain, nausea and vomiting, diarrhea, constipation, and fever. In our cases, we had difficulty in the preoperative diagnosis as the clinical changes imitated an obstruction or ischemia of the small bowel. All the cases required emergency abdominal surgery and partial jejunal resection. The aim of this article was to present three cases of mesenteric panniculitis of the small bowel mesentery requiring emergency surgery together with a short review of the literature.
