Introduction: Factor VII (FVII) deficiency, a rare bleeding disorder, can manifest as an autosomal recessive congenital or an acquired coagulopathy. Acquired FVII deficiency, although infrequently reported, presents unique challenges in understanding its mechanisms and identifying underlying causes. 
Case presentation: We present a case of acquired FVII deficiency discovered in a 23-year-old female patient with no apparent underlying disease. The patient exhibited spontaneous ecchymosis and gingival hemorrhage, along with low FVII activity and isolated prolongation of prothrombin time. Extensive laboratory investigations excluded liver dysfunction, familial deficiency, vitamin K deficiency, and inhibitory antibodies. Prompt treatment with Fresh Frozen Plasma (FFP) and bypassing agents resulted in a favorable response and resolution of hematomas. 
Conclusion: Acquired FVII deficiency was identified with bleeding symptoms in association with prolonged prothrombin time and a low level of FVII activity. In literature, this deficiency has been associated with various conditions such as sepsis, aplastic anemia, stem cell transplantation, and neoplasms, although approximately 14% of cases remain idiopathic. Clinical outcomes remain generally poor, with limited complete remissions reported.
