Afibrinogenemia is a rare inherited bleeding disorder characterized by the complete absence of fibrinogen, a clotting protein essential for normal blood coagulation. We present a case of a 13-year-old girl diagnosed with afibrinogenemia at the age of 1 month, now admitted due to cellulitis in the lower back. Here, we have examined how to diagnose a case of these uncommon conditions and emphasized the management and treatment strategy for such a case.
