Case report A male infant was born at 39 weeks of gestation, with birth weight (3.1 kg) and body length (49 cm) (both 50th percentile). The occipitofrontal circumference was 33 cm (25th percentile). The newborn’s face was inexpressive due to complete facial diplegia, bilateral ophthalmoplegia with impairment of the vertical gaze of the right eye, palpebral ptosis, a carp-shaped mouth, and a high-arched palate. Muscle and skeletal abnormalities were also apparent, including the absence of the pectoralis major and trapezius muscles, as well as left cubitus valgus; left hand was hypoplastic and showed 5th finger clinodactyly. These features prompted the diagnosis of Moebius-Poland syndrome. No previous cases were known in the patient’s family. Clinical examination revealed no other dysmorphic features except for micropenis. The karyotype was normal (46 XY). During follow-up, a mild psychomotor delay was confirmed by Denver Developmental Screening Test-II. Cortical-subcortical atrophy with no other structural abnormalities was observed in magnetic resonance imaging (MRI) of the brain. Delayed puberty was recorded when the patient was 15 years of age (Tanner stage I was recorded after physical examination). The testicular volume (measured using a Prader orchidometer) was 2 ml. Anosmia-tested by a standard olfactory test (CCCRC)- was not present. An endocrinological investigation revealed low baseline serum FSH (0.5 mU/ml), LH (0.1 mU/ml) and testosterone (2 ng/dl) levels. To confirm the suspected hypogonadotropic hypogonadism, a gonadotrophin releasing hormone stimulation test was performed and a very subnormal response obtained (after 180 min and 24 h FSH concentrations were 3.5 mU/ml and 0.7 mU/ml, respectively, and LH concentrations 0.7 mU/ml and 0.2 mU/ml, respectively). GH, TSH, and ACTH levels were normal. A further MRI scan of the brain showed no pathological lesions in the hypothalamus or pituitary gland. With a diagnosis of hypogonadotropic hypogonadism established, the child was treated with gonadotrophic hormone followed by depot preparations of testosterone. The patient eventually reached a normal weight and height and attained full sexual development (final testicular volume 6–8 ml). Discussion 1 2 4 6 6 1 6 1 3 5 6 Fig. 1 Patient photo  1 3
