Primary Ewing sarcoma of the kidney presenting as haematuria in a pregnant woman - A case report highlighting the diagnostic and therapeutic dilemmas of the condition in pregnancy.

Primary Ewing sarcoma of the kidney is an extremely rare yet aggressive tumour. We present a 31-year-old pregnant female who presented to the emergency department with macroscopic haematuria and an ultrasound scan demonstrating a right renal mass. On magnetic resonance imaging, the lesion had features concerning for malignancy. She underwent a radical nephrectomy and was commenced on a personally tailored chemotherapy regime designed to permit healthy delivery of her baby while adequately treating her disease. This highlights an extremely rare differential for a renal mass which should be considered in rapidly growing renal tumours of a young patient.

Osseous Sarcoidosis with a Solitary Lytic Skull Lesion: A Case Report.

Bone sarcoidosis is an uncommon manifestation of the multisystemic disease with skull involvement being rare. We present the case of a 32-year-old female who was referred by her General Practitioner with a left calvarial lesion on a background of previous unilateral 7th nerve palsy and diabetes mellitus. Images demonstrated a left frontoparietal calvarial osteolytic lesion. She underwent resection by the neurosurgical team with histopathological study revealing noncaseating granulomas, consistent with sarcoidosis. Given absence of other systemic features of sarcoidosis, she did not undergo systemic treatment.
