Anna Kępczyńska-Nyk, Marta Muszel, Mikołaj Radziszewski, Kamil Wocial
19-year-old hirsute woman with obesity, skin lesions with features of acanthosis nigricans around neck, armpits, thoracic cage and wrists escalating for couple of months, elevated testosterone and insulin plasma levels was admitted to hospital to perform diagnostic approach. The final diagnosis was hyperandrogenism-insulin resistance-acanthosis nigricans syndrome (HAIR-AN syndrome), considered as a subtype of policystic ovary syndrome (PCOS) and impaired glucose tolerance. HAIR-AN is characterized by coexistence of: hyperandrogenism (HA), insulin resistance (IR) and acanthosis nigricans (AN)...

Non-alcoholic fatty liver disease (NAFLD) in children is becoming a major health concern. A "multiple-hit" pathogenetic model has been suggested to explain the progressive liver damage that occurs among children with NAFLD. In addition to the accumulation of fat in the liver, insulin resistance (IR) and oxidative stress due to genetic/epigenetic background, unfavorable lifestyles, gut microbiota and gut-liver axis dysfunction, and perturbations of trace element homeostasis have been shown to be critical for disease progression and the development of more severe inflammatory and fibrotic stages [non-alcoholic steatohepatitis (NASH)]...

BACKGROUND/AIMS: The role of lipid profile in predicting the risk of Type 2 diabetes mellitus (T2DM) in children is not clearly established. Our aim is to screen non-diabetic children aged 10-14 years for risk of developing T2DM and evaluate the association of abnormal lipids and socioeconomic status (SES). METHODS: Data on race/ethnicity, family history, body mass index percentile, blood pressure and presence of neck pigmentation (acanthosis nigricans) were collected from 149 non-diabetic children...

Alstrom's syndrome (AS) is a rare autosomal recessive ciliopathic condition affecting 1:10,00,000 children. It's a single gene disorder of ALMS1 on chromosome 2 with multisystem involvement with cone-rod retinal dystrophy causing juvenile blindness, obesity, insulin resistance, type 2 Diabetes mellitus, hypogonadism and sensorineural hearing loss. Till now only 800 patients with this disorder has been identified so far. In this report, we describe the case of a 9-year old male boy from south India. He had been initially referred for polyphagia, polyuria, polydipsia, generalized weakness from 1 weeks...

We discuss a 48-year old, who presented with upper epigastrium pain associated with early satiety and significant weight loss. Physical examination revealed a thickening and darkening of skins around the skin folds, scalp, back and front of abdomen. A diagnosis of gastro-esophageal junction adenocarcinoma was confirmed by oesophagogastroduodenoscopy (OGDS) and biopsy. The biopsy of the skin lesion revealed a diagnosis of acanthosis nigricans, He underwent a total gastrectomy followed by adjuvant chemo-radiotherapy...

Paraneoplastic itch occurs as the result of a systemic reaction to an underlying malignancy. Paraneoplastic itch is most commonly associated with lymphoproliferative malignancies and solid tumors that result in cholestasis. Paraneoplastic itch may occur in the absence of a primary rash or in association with dermatologic conditions such as erythroderma, acanthosis nigricans, dermatomyositis, Grover's disease, and eruptive seborrheic keratosis. Treatment of paraneoplastic itch is centered on targeting the underlying malignancy responsible for the systemic reaction...

A 55-year-old man presented with oral mucosal ulcers, blackening of both hands, and hyperpigmentation on axillary, anal, and inguinal regions for the last 3 months, which were all progressive. The patient was referred to the oncology department with the diagnosis of acanthosis nigricans for investigation of an underlying malignancy. He was a smoker. A computed tomography scan of thorax revealed enlarged mediastinal lymphadenopathies and a lesion on the left upper lobe. Fine-needle aspiration biopsy of the mediastinal lesion was consistent with squamous cell carcinoma, and biopsies of the skin and oral mucosal lesion also further confirmed the diagnosis of acanthosis nigricans...

Alström syndrome is a clinically complex disorder characterized by progressive degeneration of sensory functions, resulting in visual and audiological impairment as well as metabolic disturbances. It is caused by recessively inherited mutations in the ALMS1 gene, which codes for a centrosomal/basal body protein. The purpose of this study was to investigate the genetic and clinical features of two Tunisian affected siblings with Alström syndrome. Detailed clinical examinations were performed including complete ophthalmic examination, serial audiograms and several biochemical and hormonal blood tests...

Insulin receptor mutations cause extreme insulin resistance resulting in acanthosis nigricans and hyperandrogenism. We report a pre-menarchal adolescent female with normal weight, with severe acanthosis nigricans, acne, and hirsutism. Initial investigation revealed elevated fasting and post-prandial insulin and high testosterone and androstenedione levels. Her father had frequent complaints of hypoglycemia. Coding sequence and splice junction analysis of the INSR gene, in our patient and her father, revealed a heterozygous missense mutation in the β subunit of the insulin receptor (Arg1131Trp), resulting in receptor loss of function...

UNLABELLED: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism (H), oligo-anovulation (O) and / or polycystic ovaries (P). There is currently little information on perinatal complications. OBJECTIVE: to investigate obstetric and neonatal characteristics of women with PCOS in our population. MATERIAL AND METHODS: we studied 87 pregnant women with PCOS (categorized in four phenotypes according Rotterdam Consensus: A (H + O + P) n = 53; B (H + O) n = 9; C (H + P) n = 16 and D (O + P) n = 9) and 96 without PCOS (control)...

Skin lesions are frequently encountered in clinical practice which can be a presentation of systemic diseases not excluding an occult malignancy. Commonly reported paraneoplastic dermatologic manifestations include acanthosis nigricans, dermatomyositis, erythroderma, hypertrophic osteoarthropathy, Sweet syndrome, and paraneoplastic pemphigus (PNP). PNP is a rare autoimmune mucocutaneous disease characterized by severe stomatitis, polymorphic skin eruptions, and associated underlying neoplasms most commonly non-Hodgkin's lymphoma, chronic lymphocytic leukemia, and Castleman disease...

Patients suffering from diabetes type II develop several skin manifestations including cutaneous infections, diabetic dermopathy, diabetic bullae and acanthosis nigricans. Diabetic micro- and macroangiopathy as well as diabetic neuropathy are believed to play a crucial role in the development of diabetic skin disorders. A reduced cutaneous nerve fiber density was reported in diabetic subjects, which subsequently leads to impaired sensory nerve functions. Using an innervated skin model, we investigated the impact of human diabetic dermal fibroblasts and keratinocytes on porcine sensory neurons...
