Laron syndrome (LS) is a rare, genetic disorder inherited in an autosomal recessive manner. The disease is caused by mutations of the growth hormone (GH) gene, leading to GH/insulin-like growth factor type 1 (IGF1) signalling pathway defect. A 13-month-old, male child, born of second-degree consanguineous marriage presented with short stature (57 cm, below- 3 SD) with normal head size, mild motor developmental delay, micropenis and bone age of 9 months. Basal GH was 28.7 ng/ml (normal 1-13.6 ng/ml). IGF-1 was less than 20 ng/ml (normal up to 170 ng/ml). GH stimulation test done using clonidine revealed increased levels. Post stimulation levels at 30 min, 60 min, 90 min (ng/ml) were 29.3, 37.9, 29.3 respectively, which was suggestive of resistance to GH that is laron dwarfism. Treatment is focused on improving growth and generally includes injections of insulin-like growth factor 1 (IGF-1). This case is being reported for its rarity and early detection.

The differential diagnosis for precocious puberty in a young female includes peripheral causes. This case report documents a rare cause of isosexual precocious puberty, a juvenile granulosa cell tumour of the ovary–and a brief literature review. A one year-old baby girl presented with mass abdomen, vaginal discharge and rapid onset of pubertal development. She underwent an exploratory laparotomy for tumour resection. Pathology reported a juvenile granulosa cell tumour of the ovary. Early stage granulosa cell tumor surgically treated has good prognosis. Adjuvant chemotherapy is not indicated in this setting.
