RESUMEN
OBJECTIVES: Primary hyperparathyroidism (PHPT) in paediatric and adolescent age group presents with some unique challenges for clinicians. While the disease in the adult counterparts presents with symptoms which are described quite extensively in literature, children/adolescents have manifestations which are quite different and severe compared to the former. The present case series aimed to highlight the peculiarities of presentation of PHPT in children and adolescents. CASE PRESENTATION: In this case series, we present experience of 5 cases of PHPT in children and adolescents from our centre. We compared our data with the data already available in literature. We have also described salient presenting features of PHPT in individuals less than 19 years old previously reported in literature and pointed out the specificities of this disease at this age group. CONCLUSIONS: PHPT in children and adolescents should be considered as a separate entity compared to that in adults, given its unique features, such as rachitic features, and severity of different presenting phenotypes. Persistence of rachitic features despite vitamin D correction, pancreatitis, bilateral nephrolithiasis and otherwise unexplained psychiatric abnormalities of insidious onset require greater clinical vigilance and serum/urine calcium testing to rule out this uncommon yet possible entity.

Pulmonary renal syndrome (PRS) is characterized by both diffuse alveolar haemorrhage and glomerulonephritis as pathological features. Several immunologic and non-immunologic mechanisms including anti-neutrophil cytoplasmic antibody (ANCA)-positive vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus are commonly involved in the pathogenesis of the syndrome. We herein present a 60-year-old woman, non-smoker, who presented with fever, polyarthralgia, and the spreading of generalized purpuric rashes. The patient displayed rapid deterioration over the following two weeks marked by progressive declining renal function followed by haemoptysis. The patient was subsequently diagnosed with PRS, which was confirmed by the radiological evidence of alveolar haemorrhage and the histopathological evidence of pauci-immune glomerulonephritis. All immune markers including ANCA were negative. The patient was successfully treated with hemodialysis and immunosuppressive therapy. ANCA-negative vasculitis is a rare entity and even more rare as an etiology of PRS. An early diagnosis of this disease and its timely intervention is crucial.
