In this case series, subtype of FSGS, active disease state of NS, central venous catheters, and some inherited and acquired thrombotic risk factors have been identified as contributory factors for the development of thrombosis in children with NS.

Patients with Hodgkin lymphoma (HL) usually present with lymphadenopathies. Osseous involvement at presentation is extremely rare. Occurrence of both eosinophilia and osseous involvement has not been reported frequently. We present an adolescent female complaining of lower back pain for 6 months, in whom, multifocal vertebral involvement and peripheral blood eosinophilia preceded the final diagnosis of HL.

Severe essential cryofibrinogenemia is rare in childhood, and both the diagnosis and the management are challenging for pediatricians. An 11-year-old male, who had already lost two digits following cold exposure, was referred after multiple visits to various hospitals and subsequently diagnosed as primary cryofibrinogenemia. His history revealed unresponsiveness to calcium channel blockers, acetyl salicylic acid, pentoxifylline, dextran, and steroids. Stanozolol (2 mg/day, orally) prophylaxis was initiated and no new skin lesions developed following starting this treatment. Some of the newly formed lesions at the onset of stanozolol healed.
