Cytophagic histiocytic panniculitis (CHP) is a recently recognized entity that frequently poses a perplexing diagnostic problem. Although the classical case presents with a relapsing fever, subcutaneous nodules, pancytopenia and liver dysfunction, most patients have in addition a multitude of other manifestations which confuse the clinical picture. Notwithstanding the variable clinical course, the disease frequently terminates in fatal hemorrhage. Diagnosis is based on histological features. A lobular
panniculitis
with an infiltrate of cytologically benign cytophagocytic histiocytes in skin nodules is the sine qua non of CHP. Hence, a deep skin biopsy which includes subcutaneous fat is mandatory to establish the diagnosis. Published information regarding this newly described entity remains scarce and we report two cases of CHP, one occurring in a 30-year-old Kadazan man and another in a 17-year-old Chinese woman seen at the University Hospital, Kuala Lumpur. The latter case presented with exudative ascites, an unusual feature, possibly due to intra-abdominal
panniculitis
. In addition, we record the development of
cirrhosis
in the same patient.

Alpha 1-antitrypsin is the primary serum proteinase inhibitor. Alpha 1-antitrypsin deficiency, especially the ZZ genotype, has been linked mainly to emphysema and
cirrhosis
; it is also associated with paniculitis. A case of alpha 1-AT-associated
panniculitis
was documented in a 13-year-old girl in whom a deficiency of the enzyme was known to be present from infancy. This is unusual, since alpha 1-AT
panniculitis
previously was described in older patients without prior knowledge of the duration of the deficiency. Our patient developed erythematous, subcutaneous nodules subsequent to trauma, which later developed into deep, painless ulcers. We report this case so that the condition may be suspected in patients with
panniculitis
. The diagnosis may be confirmed by measuring quantitative alpha 1-AT serum levels and by enzyme genotyping. The treatment of choice is dapsone.

Alpha 1-Antitrypsin is the principal serum protease inhibitor. In addition to the well-recognized association with early-onset emphysema and
cirrhosis
, alpha 1-antitrypsin deficiency may be associated with
panniculitis
. In this article we describe three patients in whom the recognition of certain clinical and histologic features of
panniculitis
eventually led to the diagnosis of alpha 1-antitrypsin deficiency. Two of our patients were young adults and one was a child. All three had draining,
panniculitis
, or cellulitis-like lesions at sites of prior trauma. The histopathologic findings were characterized by liquefactive dermal necrosis and collagenolysis of the fibrous septa of the subcutis. The combination of these clinical and microscopic findings should suggest the diagnosis of alpha 1-antitrypsin deficiency
panniculitis
. The suspicion can be verified by obtaining quantitative serum levels and enzyme phenotyping. The identification of the alpha 1-antitrypsin deficiency state as the cause of a distinct type of
panniculitis
adds additional evidence for the elimination of the term Weber-Christian disease.

Genetically determined deficiency of alpha-1-antitrypsin, the primary serum protease inhibitor, can result in pulmonary emphysema or
liver cirrhosis
, and
panniculitis
may be an early symptom. A case of recurring
panniculitis
in a 29 year-old woman is described, which led to the diagnosis of severe alpha-1-antitrypsin deficiency (Pi ZZ). Serum alpha-1-antitrypsin levels should be measured in patients presenting with
panniculitis
.

Alpha(1)-antitrypsin deficiency, a relatively frequent mutation in the population, is associated with the development of panlobular emphysema and
liver cirrhosis
. The deficiency is in rare cases associated with the development of
panniculitis
, and very differentiated clinical courses have been reported in the literature. We report a case of
panniculitis
in a patient with alpha(1)-antitrypsin deficiency and describe briefly the pathophysiology of the disease and current treatment possibilities.

Alpha-1 antitrypsin (AAT) is a protein that prevents enzymes such as elastin from degrading normal host tissue. Individuals who are deficient in AAT (those with levels < 11 micromol/L) are at risk for developing such clinical manifestations as emphysema,
cirrhosis
,
panniculitis
, and anticytoplasmic neutrophilic antibody (C-ANCA)-positive vasculitis (Wegener's granulomatosis). Estimates suggest that 75 to 85% of those with severe deficiency of AAT will develop emphysema. Smoking appears to be the most important risk factor for the development of emphysema among AAT deficient persons. Severe deficiency of AAT also seems to be associated with a shorter lifespan. Among smokers, mild to moderate reductions in AAT levels may be associated with a more rapid decline in lung function. Diagnosis of AAT deficiency is made by measuring serum levels of AAT and, if reduced, an effort should then be made to identify the genetic abnormality responsible for the reduction. A recent evidence-based review has offered testing recommendations for AAT deficiency and includes the recommendation that all patients with COPD be tested for AAT deficiency. Augmentation with an intravenous form of purified pooled human plasma has been shown to increase the serum levels of AAT among deficient patients and its use appears to impact the rate of forced expiratory volume in 1 second (FEV (1)) decline and overall survival; to date, no confirmatory, large, prospective, randomized trials are available.

Non-alcoholic steatohepatitis (NASH) is one of the most common liver disorders. This is highly prevalent in obese and diabetic subjects. Persons with central obesity are at particular risk. Other clinical predictors are age more than 40-50 years and hyperlipidemias, but none of these factors is invariable for causation of NASH. Other reported associations are, celiac disease, Wilson's Disease and few other metabolic diseases. Drugs, particularly amiodarone, tamoxifen, nucleoside analogues and methotrxate have also been linked to NASH. The disease is evenly distributed in both sexes but advanced disease is more common in women. Ethnic variation exists and African Americans are less affected than Hispanic Americans. Specific clinical features of NASH are infrequent. Patients usually come to clinical attention by elevated liver enzymes found on routine evaluation but on history, about two third of patients will admit to have mild fatigue and about half will report right upper quadrant pain. Rarely, patient may present with a complication of
cirrhosis
. Physical examination may reveal hepatomegaly and splenomegaly. Research in last few years has stressed that development of steatosis, stetohepatitis, fibrosis with subsequent
cirrhosis
are most probably the result of insulin resistance. Therefore, clinical features may reflect existence of insulin resistance. Obesity, particularly central obesity is most important of these. Patients may have sleep apnea syndrome. Hypertension and manifestations of diabetes mellitus like polyuria, polydypsia, and neurological deficits may occur. Patients may have varying combination of obesity, diabetes, hyperlipidemia, hypertension and impaired fibrinolysis (syndrome X). Children with insulin resistance may show acanthosis nigricance. Patients with polycystic ovary syndrome, which consists of insulin resistance, diabetes, obesity, hirsutism, oligo or polymenorrha and hyperlipidemia may have NASH. Other rare manifestations of insulin resistance, which can be seen in patients of NASH are lipomatosis, lipoatrophy/lipodystrophy and
panniculitis
. Most other rare conditions known to cause NASH like peroxisomal diseases, mitochondialpathies, Weber-Christian disease, Mauriac syndrome, Madelung's lipomatosis and abetaliopprotenemia also have insulin resistance. This is believed that primary defect underlying insulin resistance is impairment in postreceptor pathways (through tyrosine kinase activity) of insulin action. Primary defect in insulin receptors appear uncommon. This results in down regulation of insulin receptor substance 1 (IRS-1) signaling by excess free fatty acids. In muscle, activated IRS-1 promotes translocation of glucose transporter protein 4 (GLUT4) to cell membrane. As a result, monocyte glucose uptake by GLUT4 increases glucose disposal from blood and reduced need for insulin. PKC-0 is a likely candidate as serine kinase in muscle regulated by fatty acids that can impair the activation of IRS-1. Insulin resistance is usually evaluated by fasting insulin levels, Quantitative Insulin Check Index (QUICKI) and Homeostasis Model Assessment of Insulin Resistance (HOMA), C-peptid/insulin ratio oral glucose tolerance test and hyper insulinemic euglycemic clamp. The clamp technique is considered the gold standard.

Lipomembranous
panniculitis
is a peculiar type of fat necrosis and has been reported with several clinical conditions, commonly with peripheral vascular diseases. We are reporting a case of a 68-year-old woman with known
liver cirrhosis
and diabetes who presented with painful erythematous swelling of the right leg. Histological examination revealed microcystic changes within the subcutaneous fat. The microcysts were lined by acellular, eosinophilic membrane forming pseudopapillae and stained with periodic acid-Schiff stain. This histological feature is diagnostic of lipomembranous
panniculitis
. The pathologists should be aware of this entity because it aids the clinicians in investigating for associated clinical disorders.

Alpha1-antitrypsin deficiency is a genetic disorder which contributes to the development of chronic obstructive pulmonary disease, bronchiectasis,
liver cirrhosis
and
panniculitis
. The discovery of alpha1-antitrypsin and its function as an antiprotease led to the protease-antiprotease hypothesis, which goes some way to explaining the pathogenesis of emphysema. This article will review the clinical features of alpha1-antitrypsin deficiency, the genetic mutations known to cause it, and how they do so at a molecular level. Specific treatments for the disorder based on this knowledge will be reviewed, including alpha1-antitrypsin replacement, gene therapy and possible future therapies, such as those based on stem cells.
