Van Wyk Grumbach Syndrome and Ovarian Hyperstimulation in Juvenile Primary Hypothyroidism: Lessons From a 30-Case Cohort.

Context: Prolonged hypothyroidism in children commonly causes short stature with delayed bone maturation, and delayed puberty. However, a paradoxical occurrence of peripheral precocious puberty and pituitary enlargement in chronically untreated juvenile hypothyroidism was first reported by Van Wyk and Grumbach in 1960.

Objective: To create increased awareness and a better understanding of this clinical entity among emergency room physicians, pediatricians, surgeons, gynecologists and oncologists.

Endometrial stromal sarcoma: An aggressive uterine malignancy.

Endometrial stromal sarcoma (ESS) is an aggressive uterine sarcoma. We report a case of a large endometrial stromal sarcoma in a 42 year nulliparous woman with chronic kidney disease presenting with acute urinary retention and irregular per vaginal bleeding. Ultrasound and Doppler imaging revealed a heterogeneous mass in the endometrial cavity with internal vascularity.

Infradiaphragmatic extralobar pulmonary sequestration: masquerading as suprarenal mass.

Pulmonary sequestration is a rare malformation, wherein a portion of lung is non-functional and is not in normal continuity with the tracheo-bronchial tree, and may derive its blood supply from systemic vessels. Two types are described: Intralobar and extralobar types. Intralobar sequestration is more common type, which shares visceral pleura of the involved lobe and is localized within the normal pulmonary parenchyma.
