Cohen syndrome is a rare genetic disorder consisting of truncal obesity, hypotonia, mental retardation, microcephalia, characteristic facial appearance and ocular anomalies. Other diagnostic clinical features include narrow hands and feet, low growth parameters, neutropenia and chorioretinal dystrophy. Acanthosis nigricans is a cutaneous disorder characterized by hyperpigmentation and papillomatosis. Syndromal acanthosis nigricans may occasionally appear as a feature of several specific syndromes. We report a patient showing the typical characteristics of Cohen syndrome with acanthosis nigricans and hyperinsulinemia.

We report two unrelated cases of Costello syndrome, presenting with poor postnatal growth, mild mental retardation, poor feeding, curly hair, coarse characteristic face, loose skin, hypotonia, and cardiac involvement. Nasal papilloma and acanthosis nigricans were the most characteristic features of this syndrome. Both cases had atrial fibrilation from infancy to early childhood. One patient had hypertonia in the lower extremities and pes equinovarus, while the other had hypotonia and pes planovalgus.

The monosomy 1p36 syndrome is a cause of syndromic obesity. It is characterised by psychomotor delay, hypotonia and typical craniofacial dysmorphism. Other features commonly associated are behavioural anomalies including hyperphagia and self-injuring, seizures, congenital heart disease and hypothyroidism. The authors report the case of a 9-year and 5-month-boy referred to the paediatric endocrinology clinics for morbid obesity. Clinical findings were generalised obesity with a body mass index >95th centile, acanthosis nigricans of the neck, arms with self inflicted lesions, deep-set eyes, straight eyebrows, broad nasal bridge and pointed chin. He was unable to walk and had no expressive language. Cytogenetic analysis identified 1p36.33-pter deletion (~139 Mb terminal deletion in chromosome 1 short arm) and Y chromosome duplication. The blood analysis showed insulin resistance and dyslipidaemia. The authors emphasise the need to consider monosomy 1p36 as a cause of severe psychomotor delay and obesity.

The Bardet-Biedl syndrome (BBS), a rare autosomal recessive disorder, was first described by Bardet and Biedl in 1920. Here, we are reporting a case of the Bardet-Biedl syndrome with hypokalaemic paralysis. A 22 years old male patient presented with an acute onset, rapidly progressive, flaccid weakness in all four limbs. An examination revealed a moon shaped face, acanthosis nigricans, lower limb polydactyly, central obesity, small testicular size, absence of the axillary and pubic hairs, severely impaired social adaptive functioning and retinitis pigmentosa. The central nervous system examination showed hypotonia, a grade zero power and absent reflexes. The laboratory reports showed that the patient had hypokalaemia and diabetes mellitus. The literature showed hypokalaemic paralysis as a rare complication of the Bardet-Biedl syndrome.
