Background: Berardinelli-Seip congenital lipodystrophy (BSCL) is a heterogeneous autosomal recessive disorder characterized by an almost total lack of adipose tissue in the body. Mutations in the AGPAT2, BSCL2, CAV1 and PTRF genes define I-IV subtype of BSLC respectively and clinical data indicate that new causative genes remain to be discovered. Here, we retrieved 341 cases from 60 BSCL-related studies worldwide and aimed to explore genotype-phenotype correlations based on mutations of AGPAT2 and BSCL2 genes from 251 cases. Read More

HAIR-AN-a syndrome of hyperandrogenism (HA), insulin resistance (IR) and acanthosis nigricans (AN)-is a specific subphenotype of polycystic ovary syndrome (PCOS), and it is seen in almost 5% of all women with hyperandrogenism. An adolescent girl aged 11 years old was referred with adrenarche, hyperandrogenism and obesity commencing at age 8. Clinical and biochemical investigations confirmed significant hyperandrogenism and insulin resistance, and a diagnosis of HAIR-AN syndrome was made after exclusion of other differential diagnoses.

Intrahepatic cholangiocarcinomas or bile duct cancers comprise approximately 10-20% of all cholangiocarcinomas and may present with right upper quadrant pain, weight loss, liver enzyme abnormalities or they may be completely asymptomatic and be picked incidentally on routine abdominal imaging. Typically, hepatocellular carcinomas have been associated with various paraneoplastic syndromes such as hypercalcemia, erythrocytosis, hypoglycemia, diarrhea and skin changes though paraneoplastic syndromes in the setting of cholangiocarcinoma do occur as well. Cholangiocarcinomas are usually associated with dermal paraneoplastic syndromes (Sweet syndrome, porphyria cutanea tarda, acanthosis nigricans, necrotic migratory erythema, erythema multiforme, bullous pemphigoid), hypercalcemia, leukocytosis and limbic encephalitis.

Immunoprecipitation with autoantibodies to the insulin receptor derived from patients with extreme insulin resistance and acanthosis nigricans revealed that the receptor is comprised of two subunits of 135 kDa (α subunit) and 95 kDa (β subunit) and that insulin induces the rapid phosphorylation of the β subunit in intact cells. Incubation of a highly purified insulin receptor preparation with [γ-P]ATP also resulted in tyrosine phosphorylation of the β subunit in an insulin-dependent manner, suggesting that the receptor itself is a tyrosine-specific protein kinase. Furthermore, a Japanese boy with insulin resistance and acanthosis nigricans was found to be heterozygous for a mutation of the insulin receptor gene that resulted in the replacement of glycine-996 with valine in the ATP binding site of the receptor.

The increasing prevalence of Metabolic syndrome (MetS) is a worldwide health problem, and the association between MetS and skin diseases has recently attracted growing attention. In this review, we summarize the associations between MetS and skin diseases, such as psoriasis, acne vulgaris, hidradenitis suppurativa, androgenetic alopecia, acanthosis nigricans, and atopic dermatitis. To discuss the potential common mechanisms underlying MetS and skin diseases, we focus on insulin signaling and insulin resistance, as well as chronic inflammation including adipokines and proinflammatory cytokines related to molecular mechanisms.
