Terra firma-forme dermatosis (TFFD) is a benign and likely underdiagnosed disorder with relatively few reports in the literature. A 46-year-old woman presented to our clinic with a 3-year history of linear TFFD extending from the upper sacrum to the midline upper back. It initially was thought to be acanthosis nigricans or lichen simplex chronicus, and a topical steroid cream was applied without success. The lesion ultimately was removed by rubbing with isopropyl alcohol, which confirmed a diagnosis of TFFD...

Pseudo-acanthosis nigricans is a common dermatological disorder that is usually difficult to treat secondary to maceration of the skin from excessive sweating, obesity, or associated with endocrine disorders. Fractional photothermolysis and chemical peeling have been reported to improve the condition. To determine whether fractional CO2 laser resurfacing or glycolic acid peel is more effective and safe option for therapy. Twenty Egyptian patients were included in the study where each patient was subjected to three sessions of both fractional CO2 on the right side of the neck and glycolic acid peel 70% on the left side of the neck...

Berardinelli-Seip congenital lipodystrophy (BSCL) syndrome is a rare genetic disorder caused by dysregulation of glycemic and lipid metabolism. We report five BSCL cases with typical clinical pictures and complications. These, to the best of our knowledge, represent the first case series from Pakistan. BSCL is characterized by marked atrophy of adipose tissue, acromegaly, acanthosis nigricans and tall stature. We could not perform genetics studies in any patient owing to non-availability of genetic laboratory in Pakistan...

INTRODUCTION: Craniosynostosis, the premature fusion of cranial sutures, is usually divided into 2 major categories: syndromic and nonsyndromic. Mutations in the FGFR1, FGFR2, FGFR3, TWIST1, and EFNB1 genes cause the common craniosynostosis syndromes Muenke, Crouzon and Crouzon with acanthosis nigricans, Apert, Pfeiffer, Saethre-Chotzen, and Craniofrontonasal. Overlapping features among craniosynostosis syndromes, phenotypic heterogeneity even within the same syndrome, especially in the case of Muenke syndrome, and inadequate clinical evaluation can lead to misdiagnosis, which molecular testing can help clarify...

Acromegaly is a systemic syndrome caused by overproduction of growth hormone. Cutaneous, endocrine, cardiovascular, skeletal, and respiratory systems are affected. Cutaneous changes in acromegaly relate to overexpression of growth hormone and insulin-like growth factor 1 on skin cells and adnexa. Dermal glycosaminoglycan accumulation and edema cause skin distention that is most prominent in the face, hands, and feet. Oily skin with large pores, hypertrichosis, and excessive sweating are common features. Pigmented skin tags, acanthosis nigricans, and psoriasis are also encountered...

STUDY OBJECTIVE: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism and chronic anovulation, which affects 5-10% of reproductive age females. Diagnosis of adult patients with PCOS is made easily with clinical and laboratory methods and the antimullerian hormone (AMH) level are accepted as a good indicator. However, there is still no complete consensus on the diagnosis of PCOS in adolescents. DESIGN: and Settings: Prospective cohort study, December 2013 to November 2014 PARTICIPANTS: The study was conducted on adolescent girls with oligomenorrhea, with at least two years since menarche...

Acne is a multifactorial and inflammatory disease of pilosebaceous follicles, which affects most adolescents. Recent epidemiological data revealed a difference in adults affected by this disease. Women have a high prevalence and incidence when compared with men, especially after 25 years of age. In contrast to what was initially thought, most of these patients do not present endocrinopathy capable of leading to the development of the lesions. When present, polycystic ovarian syndrome is the main cause. However, in these cases, acne is rarely the only dermatological manifestation; hirsutism and acanthosis nigricans are often present...

INTRODUCTION: Metabolic heterogeneity among obese individuals is thought to translate into variation in cardiovascular risk. Identifying obese people with an unfavourable metabolic profile may allow targeting preventive strategies towards those at greatest risk. This study aimed to identify clinical, biochemical and immunological differences between insulin sensitive and resistant obese subgroups, to understand the population-specific pathophysiological basis of the adverse cardiovascular risk profile in the latter group...

AIM: Hypoglycemia in childhood is very rare and can be caused by genetic mutations or insulin-secreting neoplasms. Postprandial hypoglycemia has previously been associated with insulin receptor (INSR) gene mutations. We aimed to identify the cause of postprandial hypoglycemia in a 10-year-old boy. SUBJECTS: We studied the symptomatic proband and his apparently asymptomatic mother and elder brother. All of them were lean. METHODS: Metabolic screening of the proband included a 5-hour oral glucose tolerance test (OGTT), angio-magnetic resonance imaging, and 18 F-dihydroxyphenylalanine positron emission tomography/computed tomography imaging of the pancreas...

Crouzon syndrome with acanthosis nigricans (CAN) is caused by a mutation in the fibroblast growth factor receptor ( FGFR) 3 gene that presents clinically as Crouzonoid craniofacial features in association with other anomalies such as acanthosis nigricans and benign odontogenic tumors. Diagnosis through the use of genetic mutational analysis is critical, as it alerts the surgeon to the need for careful screening for jaw tumors so that timely treatment in the form of curettage or segmental resection can be provided...
