Rachitic chest in a young adult male: Fanconi's syndrome--idiopathic type.

Presented in this paper is a case of a 36-year-old Filipino man presenting with a chronic history of intermittent proximal muscle weakness and paralysis which was associated with failure to thrive, severe bony deformities, muscle wasting and multiple electrolyte abnormalities (hypokalaemia, hypocalcaemia, hypomagnesaemia). Severe skeletal deformities led to a pathological fracture of the femoral bone and restrictive chest wall expansion during inspiration necessitating admission and consult at our institution. Correction of multiple electrolyte abnormalities was the mainstay of treatment for this case and resulted into full reversal of paralytic symptoms but skeletal and osseous abnormalities persisted. This case highlights the insidious course and subtle signs of Fanconi's syndrome leading to disfiguring skeletal deformities and abnormalities if not diagnosed early. Early suspicion and eventual diagnosis might be the key for these patients to have normal productive life devoid of crippling complications.
