ABSTRACT
Rosai-Dorfman disease (RDD) is a rare, multisystemic, histiocytic disorder that usually presents with painless cervical lymphadenopathy. We describe a case of constrictive effusive pericarditis with congestive cardiac failure in a six-year-old child as an initial presentation of RDD. The child underwent pericardiectomy and was treated with steroids, following which the symptoms resolved entirely. While tuberculosis accounts for the majority of cases presenting with constrictive pericarditis in developing countries, the presentation of RDD can be easily missed if not kept in mind as a possibility. This case report documents the unique presentation of a rare disease.
ABSTRACT
Systemic lupus erythematosus (SLE) is a multi-system disorder with a variety of clinical presentations. A wide range of renal vascular lesions (VL) is described predominantly in adult patients. The exact prevalence of renal VL in the pediatric SLE (pSLE) population is yet to be determined. A 10-year-old female patient with lupus nephritis (LN) presented with deteriorating kidney function. An exhaustive array of clinical-biochemical and pathological evaluations resulted in a diagnosis of class IV LN with thrombotic microangiopathy (TMA) associated with malignant hypertension and hypocomplementemia. Renal VL is overlooked or underreported in SLE patients, as it is neither accorded much importance in the International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification nor in the activity and chronicity scoring. The TMA lesions in LN patients can be managed following the recently devised PLASMIC score; hence, reporting such VL has therapeutic implications.
