Complete Resection of Phosphoglyceride Crystal Deposition Disease After Cardiac Surgery

Phosphoglyceride Crystal Deposition Disease of the Scapula: A Case Report and Literature Review

CASE

A 76-year-old woman presented with a 2-month history of right shoulder pain with no apparent cause. Radiography revealed an ill-defined osteolytic lesion in the right scapular spine with a pathological fracture. Malignant bone tumor was suspected, and a biopsy was performed. Pathological examination with gold hydroxamic acid staining revealed phosphoglyceride crystal deposition. Lesion curettage was performed, and her symptoms improved. No recurrence was observed at the 3-year postoperative follow-up.

CONCLUSION

Phosphoglyceride crystal deposition in the bone is an extremely rare disease. The gold hydroxamic acid staining method might be useful for the diagnosis of this condition.

Severe Functional Tricuspid Stenosis Due to Phosphoglyceride Crystal Deposition Disease in Right Atrium

This case report concerns a 72-year-old-female with severe functional tricuspid stenosis due to phosphoglyceride crystal deposition disease and a history of atrial septum closure and tricuspid valvuloplasty. Phosphoglyceride crystal deposition disease is extremely rare, and percutaneous transcatheter biopsy under intracardiac echocardiographic guidance proved to be useful for its diagnosis.
