Classic Kaposi sarcoma in an HIV-negative Han Chinese man: a case report

Kaposi sarcoma (KS) is a multifocal angioproliferativetumor of endothelial origin. Despite nearly identicalclinical and histopathologic presentations, KS isclassified into four distinct varieties: classic/sporadic,AIDS-associated, African/endemic, and iatrogenic. Allsubtypes are invariably linked to human herpesvirus-8(HHV-8) and show a male predilection. Classic Kaposisarcoma is exceedingly rare in the Asian populationand its incidence varies by region and ethnic grouppredominance. A study in the Xinjiang region of Chinafound that only 1% of classic KS cases occurred inpatients belonging to the Han Chinese ethnic group,which formulates 84% of the Taiwanese population.Therefore, classic KS is extremely rare in Taiwan, withvery few reports describing the manifestations ofdisease in this population. We report a case of animmunocompetent 68-year-old HIV-negative HanChinese man born and raised in Taiwan with classicKaposi sarcoma on his trunk and extremities

Precursor-B-cell-ALL leukemia cutis resembling lipomas: an atypical presentation of a rare entity and a review of the literature

Leukemia cutis (LC) is an extramedullary manifestationof leukemia owing to cutaneous infiltration ofneoplastic cells resulting in characteristic firm,erythematous nodules. Most cases of LC occur inpatients with acute myelogenous leukemia andchronic myelogenous leukemia. However in rarecases, LC has presented in patients with acutelymphoblastic leukemia (ALL). In these rare ALLassociatedcases, only 10 cases of precursor-B-ALL(pre-B-ALL) have been described in the literature.We report a case of a 22-year-old man with relapsingpre-B-ALL who presented with a 4-day history ofmultiple asymptomatic, soft, dome-shaped, lipomalikemounds on his scalp and chin, which exhibitedcutaneous involvement by leukemic cells. To date, thisis the first case of pre-B-ALL associated leukemia cutispresenting as soft, dome-shaped mounds resemblinglipomas

Cutaneous metastasis to the scalp as the primary presentation of colorectal adenocarcinoma

Eruptaneous metastasis is an uncommon presentation of colorectal adenocarcinoma that can occur years after diagnosis of the primary cancer or manifest as the first sign of malignancy. It is essential to diagnose these metastases immediately, as this late-stage development carries a poor prognosis. The scalp is one of the less common sites for skin metastases and nodules may be mistaken for benign entities. In this case report, we report on the case of a 61-year-old woman with CREST syndrome who presented with a cutaneous metastasis to the scalp as the first sign ofcolorectal adenocarcinoma

The glucose clamp reveals an association between adiponectin gene polymorphisms and insulin sensitivity in obese subjects

Results concerning the association of adiponectin gene polymorphisms (single-nucleotide polymorphisms, SNPs) with obesity, type 2 diabetes (T2DM), metabolic disorders and insulin resistance have not lead to definite conclusions. The aim of our study was to investigate a possible association between the -11391G>A and -11377C>G SNPs of adiponectin gene and measure of insulin sensitivity evaluated by the hyperinsulinemic-euglycemic clamp in a group of 'uncomplicated' obese subjects (with no associated comorbidities) (n=99, mean age 35 years) with a history of obesity lasting at least 10 years. The study of uncomplicated obese subjects, free of possible confounding factors that could interfere with insulin sensitivity, such as pharmacological treatment, provides a good model to assess insulin sensitivity per se. We observed that subjects homozygous for the G allele at locus -11391 had lower M (mg/kg min)/fat-free mass (FFM) index and adiponectin levels compared to subjects with GA+AA genotypes (P=0.002 and P=0.03, respectively) and subjects carrying the -11377G variant had lower M (mg/kg min)/FFM index and adiponectin levels compared to noncarriers (P=0.003 and P=0.03, respectively). Our results imply that the two promoter SNPs, -11391G>A and -11377C>G, of the adiponectin gene are associated with a reduced insulin sensitivity evaluated by hyperinsulinemic-euglycemic clamp in obese subjects. © 2007 Nature Publishing Group All rights reserved
