1/36. panniculitis caused by acinous pancreatic carcinoma.subcutaneous fat necrosis is a form of panniculitis associated with pancreatitis or pancreatic carcinoma. The massive release in the bloodstream of lipolytic enzymes such as lipase, amylase and trypsin causes these lesions. As pancreatic disease is often asymptomatic, extensive investigations are mandatory in the presence of panniculitic lesions to search for an underlying disease.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
2/36. A case of natural killer/T cell lymphoma of the subcutis resembling subcutaneous panniculitis-like T cell lymphoma.A case of nasal type natural killer (NK)/T cell lymphoma of the subcutis showing clinical and morphological features that resemble subcutaneous panniculitis-like T cell lymphoma (SPTCL) is presented. A 73-year-old man presented with swelling of the left arm and was diagnosed with panniculitis by a dermatologist. It was concluded from a skin biopsy specimen that the patient had non-Hodgkin's lymphoma of the large cell, NK/T cell type because the neoplastic cells showed polyclonal CD3 immunoreactivity. Treatment with interferon-gamma was initiated, but the patient died of disseminated intravascular coagulation and multiple organ failure 2 months after the initial symptoms appeared. However, involvement of additional organs by the lymphoma was not apparent clinically. An autopsy was not performed. A routinely stained section of the biopsy skin specimen revealed massive necrosis of the subcutaneous fat, karyorrhexis admixed with reactive histiocytes, and large atypical lymphoid cells. Immunoreactivity for polyclonal CD3 was present in the perinuclear region, but absent in the neoplastic cell membranes. CD56, CD45RO (UCHL-1), CD43 (MT1), CD45 (leukocyte common antigen), and the cytotoxic molecules perforin, granzyme B and TIA-1 were positive, but CD20 (L26), CD4, CD8, and betaF1 were negative. Epstein-Barr virus (EBV) mRNA was detected in the nuclei of neoplastic cells by in situ hybridization. Subcutaneous panniculitis-like T cell lymphoma is reported to be an EBV-negative, clonal T cell neoplasm. Although this case showed clinical and morphological features that resembled SPTCL, perinuclear polyclonal CD3 staining and membranous CD56 reactivity seen in neoplastic cells were suggestive of NK cells. Furthermore, the neoplastic cells were positive for EBV. This case is considered to be a NK/T cell lymphoma of the subcutis resembling SPTCL. It is believed that it is important to recognize such a tumor because patients may undergo a fulminant clinical course, despite the tumor being localized in the subcutaneous adipose tissue.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
3/36. Neutrophilic lobular (pustular) panniculitis associated with rheumatoid arthritis: a case report and review of the literature.Rheumatoid nodules, which affect the subcutis around joints, are the most frequent specific cutaneous lesions of rheumatoid arthritis (RA). panniculitis is a rarely reported and nonspecific complication of RA. We report a 42-year-old woman with seropositive RA who presented with a 2-month history of lower leg panniculitis. biopsy of a leg nodule showed a lobular neutrophilic infiltrate with lipophages and central basophilic necrosis. In addition, focal changes of lipomembranous fat necrosis indicative of ischemic damage were identified at the margins of the lobular infiltrate. Neutrophilic lobular panniculitis is commonly detected in panniculitis secondary to bacterial infections, pancreatitis, and factitial causes. However, this pattern of panniculitis has also been reported in some cases of erythema nodosum-like lesions found in Behcet disease or bowel bypass syndrome and in rare cases of seropositive RA. These reported histologic findings fall into the spectrum of neutrophilic vascular reactions described by Jorizzo and Daniels for RA-associated dermatoses. In view of these findings. RA and related neutrophilic dermatoses (e.g., Behcet disease) should be included in the differential diagnosis of neutrophilic lobular panniculitis.- - - - - - - - - - ranking = 2keywords = necrosis (Clic here for more details about this article) |
4/36. panniculitis mimicking lupus erythematosus profundus: a new histopathologic finding in malignant atrophic papulosis (Degos disease).We present the case of a 57-year-old woman with a 1-year history of a cutaneous eruption clinically and histopathologically characteristic of Degos disease. In one of the two cutaneous biopsy specimens taken from the trunk lesions, the histopathology consisted of necrosis and sclerosis of the subcutaneous lobules, a finding that to our knowledge has not been previously described in the cutaneous lesions of Degos disease. Two months after cutaneous biopsies were taken, the patient developed ptosis and an episode of acute abdominal pain; intestinal perforation and many characteristic lesions of visceral Degos disease involving the entire small bowel were noted at laparotomy.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
5/36. subcutaneous fat necrosis of the newborn following hypothermia and complicated by pain and hypercalcaemia.A female infant was delivered at term with complications of severe meconium aspiration and birth asphyxia. Surface cooling was performed in the first 24 hours as part of the management of her birth asphyxia. Woody erythema was noted at 24 hours, followed by the formation of red-purple nodules on the 6th day. Clinical findings in the first 24 hours were suggestive of cold panniculitis. However, clinical and histological findings progressed to be in keeping with the diagnosis of subcutaneous fat necrosis of the newborn (SCFN). Furthermore, the immediate postnatal period was complicated by pain resistant to treatment with opiates. Asymptomatic hypercalcaemia was noted on periodic testing at 7 weeks and treated by rehydration, diuretics, prednisolone, etidronate and a low-calcium and -vitamin d diet. A review of the clinical and histological findings of the relevant panniculitides occurring in the postnatal period is presented, as well as a review of the treatment of hypercalcaemia in SCFN.- - - - - - - - - - ranking = 5keywords = necrosis (Clic here for more details about this article) |
6/36. Severe panniculitis caused by homozygous ZZ alpha1-antitrypsin deficiency treated successfully with human purified enzyme (Prolastin).Severe panniculitis caused by alpha1-antitrypsin deficiency is very rare even though the ZZ phenotype occurs in 1 : 3500 of the population of northern europe. We describe a 33-year-old woman with rapidly progressing panniculitis and extensive skin necrosis with multiple life-threatening complications. Initial treatment followed by maintenance therapy with human purified enzyme (Prolastin, Bayer, Bridgend, U.K.) has been life-saving.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
7/36. Pancreatic panniculitis in an 88-year-old man with neuroendocrine carcinoma.Pancreatic panniculitis is a rare complication that occurs in 0.3-3% of patients with pancreatic diseases. Most of the cases reported to date were associated with adenocarcinoma and acute or chronic pancreatitis. We here present an 88-year-old man who was admitted to our institution with a nonfunctional neuroendocrine carcinoma of the pancreas. He subsequently developed pancreatic panniculitis and arthritis. Treatment with octreotide did not have an effect neither on progression of the carcinoma nor on development of new skin lesions. Two months after the diagnosis of pancreatic panniculitis had been made, the patient died from progressing carcinoma. A review of the literature shows that there is no congruent hypothesis for the pathogenesis of pancreatic panniculitis. Vascular damage seems to induce lipolysis by pancreatic enzymes. This eventually leads to fat necrosis. The diversity of disorders that can go along with pancreatic panniculitis suggests an unspecific damage of pancreatic tissue as a first step in the chain of events.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
8/36. Persistent painful plaque due to a brown recluse spider bite.The bite of the arthropod Loxosceles is known to cause subdermal hemorrhage, dermal-epidermal separation, inflammatory infiltrates, as well as occlusion and necrosis of small arterioles. We report a case of a brown recluse spider bite that presented as a chronic painful skin plaque, with the unusual histologic findings of a cutaneous and deep subcutaneous hyalinizing panniculitis and myonecrosis.- - - - - - - - - - ranking = 2keywords = necrosis (Clic here for more details about this article) |
9/36. Carcinoma of the pancreas with neuroendocrine differentiation and nodular panniculitis.BACKGROUND: On rare occasions tumours of the pancreas produce high amounts of pancreatic lipase. The enzyme activity in the blood and in different tissues causes a syndrome called nodular panniculitis by focal necrosis of lipids and a concomittant inflammatory reaction. CASE REPORT: A 72-year-old man was admitted to the dermatology clinic with the diagnosis of erythema nodosum. The patient had been well until 3 months earlier when painful red nodes developed on the skin of both shanks. He complained of profuse night sweating and a weight loss of 10 kg within that time but did not have fever. He also had noticed a painful swelling of his right index finger, left middle finger and the third toe on his left foot. biopsy of the nodes revealed a focal necrosis of fatty tissue. Laboratory examinations showed a highly elevated concentration of serum pancreatic lipase. Further investigations showed a tumour in the pancreas and several osteolytic lesions. Tumour biopsy revealed a neuroendocrine carcinoma. After tumour resection serum lipase level immediately fell to almost normal values, and all skin and bone manifestations disappeared quickly. CONCLUSION: Due to its clinical appearance the panniculitis syndrome is most often mistaken for either erythema nodosum or rheumatoid arthritis. A resection of the tumour after correct diagnosis should always be considered because the widespread manifestations in the skin and bones do not represent distant metastasis and have a very good chance to dissolve completely.- - - - - - - - - - ranking = 2keywords = necrosis (Clic here for more details about this article) |
10/36. Munchausen's syndrome presenting as severe panniculitis.factitious disorders may trouble any physician during his/her career. A considerable number of cases of Munchausen's syndrome (self-induced disorder) are misdiagnosed in clinical practice. A 36-year-old woman was admitted to our hospital because of fever and abdominal pain. physical examination showed signs of inflammation of the abdominal wall, and histological examination revealed severe panniculitis. We investigated various aetiologic factors that could probably be related to fat necrosis, but we found no explanation of the phenomenon until we verified the diagnosis of Munchausen's syndrome. 2 years later, the patient underwent surgery for removal of needles, which she herself had deliberately located under her skin. High index of suspicion and physician's persistence are necessary to make the correct diagnosis in the various protean manifestations of Munchausen's syndrome.- - - - - - - - - - ranking = 1keywords = necrosis (Clic here for more details about this article) |
