Fadime Ersoy Dursun, Erdal Akyar, Gokhan Uygun, Zafer Baslar, Bengu Cobanoglu


Introduction: Isolated and combined factor deficiencies are known to occur in systemic primary amyloidosis. The most common factor deficiency known in these cases is isolated factor X deficiency. Other factor deficiencies are relatively less frequent. Isolated factor VII deficiency occurs very rarely in cases of systemic primary amyloidosis.
Case report: A 58-year-old male patient previously presenting to another health center with complaints of generalized edema, fatigue, and itching had proteinuria and then he was diagnosed with systemic primary amyloidosis after the renal biopsy for proteinuria etiology. The patient’s laboratory tests showed prolongation of prothrombin time and factor VII deficiency. The patient responded well to the treatment for primary amyloidosis and factor VII deficiency.
Discussion: In cases of systemic primary amyloidosis, if the etiology of prolonged prothrombin time involves no liver disease, warfarin use, or malabsorption, physicians should always keep in mind rare factor deficiencies such as factor VII deficiency, along with common factor deficiencies.
