OBJECTIVE To assess the effect of age on glucose metabolism by examining 1) glucose metabolism in young and middle-aged subjects when total or regional adiposity is taken into account and 2) in vitro glucose transport in adipose tissue explants from young and middle-aged women paired for total and abdominal adiposity. RESEARCH DESIGN AND METHODS Study 1: body composition, subcutaneous abdomin...

Hemangiosarcoma is a malignant tumor of vascular endothelial cell origin. The occurrence of hemangiosarcoma in nonhuman primates has been rarely documented. An adult male rhesus monkey was reported having a firm subcutaneous swelling, approximately 4.5 cm in diameter, on the ventral midline of the abdomen. Fine-needle aspiration, microbial culture, biopsy, radiographs, exploratory laparotomy, h...

OBJECTIVE To develop mixed models for examining longitudinal associations between rates of change in visceral, subcutaneous abdominal, and total body fat with rates of change in fasting insulin (FI) and insulin sensitivity (SI) over 3 years in children. RESEARCH METHODS AND PROCEDURES Seventy-seven children (mean age, 8.3 years at baseline) from Birmingham, Alabama, with three or more annual ...

Kimura’s disease (KD) is a chronic inflammatory disorder with unknown etiology, most commonly manifesting as painless unilateral cervical lymphadenopathy or subcutaneous masses in the head or neck region. The disease is characterized by a triad of painless subcutaneous masses in the head or neck region, blood and tissue eosinophilia, and markedly elevated serum immunoglobulin E levels. Kimura’s...

Skin metastasis secondary to cancer of the prostate is rare and the prognosis is poor. A 65-year-old male patient diagnosed with metastatic colon carcinoma presented with polyuria and subcutaneous nodular mass on dorsal side of the corpus penis. The serum prostate specific antigen (PSA) level was 111.1 ng/mL and therefore the patient underwent transperineal prostate biopsy. Pathology reported a...

Epidermal cysts are common, benign, intradermal or subcutaneous, typically asymptomatic masses, ranging from 1 to 4 cm in size. They may occur anywhere in the body, with a predilection for the face, neck, and trunk. Transformation to squamous-cell carcinoma is rare. We present a case of a 61-year-old male patient with a large, growing mass in his posterior left gluteal region. Given the concern...

Background The interplay between adiponectin and resistin, the two adipokines of opposite effects, may determine the metabolic profile of obese individuals and development of obesity-related complications. The current study was conducted to assess how adiponectin/resistin interplay in sera and adipose tissues may influence the metabolic profile of obese and normal-weight subjects. Methods Con...

We present the case of a 69-year-old woman with type 2 diabetes mellitus who developed severe insulin resistance associated with insulin injections into a subcutaneous mass formed by repeated injections into the same site over many years. The patient (height, 150 cm; weight, 79 kg; BMI, 35.1 kg/m) was admitted to Tenri Hospital with severe insulin resistance. She was undergoing insulin therapy ...

Glucocorticoids have major effects on adipose tissue metabolism. To study tissue mRNA expression changes induced by chronic elevated endogenous glucocorticoids, we performed RNA sequencing on the subcutaneous adipose tissue from patients with Cushing's disease (n=5) compared to patients with nonfunctioning pituitary adenomas (n=11). We found a higher expression of transcripts involved in severa...

Myopericytoma (MP) is a benign tumor composed of cells that show apparent differentiation towards putative perivascular myoid cells called myopericytes. It arises most commonly in the dermis or subcutaneous tissue of the extremities in adults. The most common presentation is a well-circumscribed, slow-growing painless firm mass. A 45-year-old woman presented with a 2-year history of a painless,...
