Severe hemorrhagic diathesis caused by hemophilia A (factor VIII:C deficiency) was diagnosed in 2 related Quarter Horse colts. Clinical signs consisted of dyspnea and dysphagia attributable to cranial cervical hematoma in one colt and to intra-abdominal hemorrhage resulting in death of the second colt. Factor VIII:C deficiency, a defect of the intrinsic coagulation pathway, is suggested by results of coagulation studies--prolonged activated partial thromboplastin time, normal prothrombin time, and normal primary bleeding time. The diagnosis was confirmed by results of factor VIII:C assays. Hemophilia A is inherited as an X chromosome-linked trait.

A 78-year-old man presented with a 5-day history of epistaxis and spontaneous bruising, and a 2-day history of acute dysphagia. Barium swallow, computerized tomography scan of the chest and upper gastrointestinal endoscopy were suggestive of an upper oesophageal tumour, although biopsies failed to confirm this. Investigations including a raised activated partial thromboplastin time led to the detection of an inhibitor causing functional factor VIII deficiency. Following treatment with intravenous human immunoglobulin, oral prednisolone and oral cyclophosphamide, the patient's dysphagia resolved. There was a resolution of the findings seen at the initial endoscopy and on computerized tomography scan of the chest, consistent with an oesophageal haematoma. Follow-up endoscopy failed to detect recurrence or an aetiological factor.

Acquired haemophilia A and severe acquired achalasia are both very rare conditions with unknown aetiology. Haemophilia A is a haemorrhagic disease induced by deficiency or malfunction of coagulation factor VIII. Congenital haemophilia is an inherited disease transmitted by the mother through X-linked inheritance and primarily affects males. However, acquired haemophilia A is a serious, sudden-onset, autoimmune disease that affects either sex. In addition, achalasia is a disease of the oesophagus caused by abnormal function of the nerves and muscles. It causes swallowing difficulties due to the inability of the lower oesophageal sphincter to relax during swallowing, leading to dysphagia, regurgitation and chest pain. In this report, we describe the case of a patient with severe, newly diagnosed, acquired haemophilia A with long-standing, recurrent achalasia; the achalasia had recurred 3 times despite complete and proper surgical fixation. Acquired haemophilia A is treated with immunosuppressive therapy. High-dose steroid therapy was administered for 7 months, during which the patient responded well; moreover, the achalasia did not recur for more than 2 years. The response of the achalasia to immunosuppressive therapy suggests that achalasia may be an autoimmune disorder and that there may be an association between both diseases. The findings of the present case suggest that achalasia may favourably respond to steroid therapy as a first-line treatment prior to surgery.

A 65-year-old male with no personal or familial history of bleeding disorders underwent percutaneous endoscopic gastrostomy (PEG) for neurogenic dysphagia due to subarachnoid hemorrhage. On postoperative day 6, continuous oozing of venous blood was observed at the stoma. Prothrombin time was within normal range, but activated partial thromboplastin time was prolonged. Cross-mixing test results indicated the existence of an inhibitor, and laboratory findings revealed decreased factor VIII activity and high levels of factor VIII inhibitor. The patient was diagnosed as having acquired hemophilia A, for which steroid monotherapy was effective. Acquired hemophilia A is a rare but potentially fatal disease. Clinicians should be aware of this condition in patients presenting with sudden hemorrhage after PEG or other endoscopic treatments, even in those with no apparent history of bleeding.

BACKGROUND Massive tongue hemorrhage in patients with hemophilia is a medical emergency because it can lead to airway obstruction. However, managing bleeding in patients with inhibitors is more difficult than in patients without inhibitors. We report a case of life-threatening massive tongue and retropharyngeal hematoma in a patient with hemophilia A who had inhibitors. CASE REPORT The patient was a 71-year-old man with severe hemophilia A with high-responding inhibitors. He was admitted to our hospital with dysarthria and dysphagia secondary to a massive tongue hematoma. Although bypassing therapy was started immediately after admission, he rapidly developed an airway obstruction and cardiopulmonary arrest secondary to suffocation. Cardiopulmonary resuscitation and surgical cricothyrotomy were performed, which restored his pulse and breathing. On day 5 of hospitalization, he underwent tracheotomy under inhibitor-neutralizing therapy, and we began emicizumab on day 19 of hospitalization to prevent further bleeding events. He recovered and was transferred to another hospital for rehabilitation on day 64 of hospitalization. CONCLUSIONS Because tongue hematomas progress dramatically within a few days, prompt airway maintenance by tracheotomy under appropriate hemostatic therapy must be considered. Furthermore, emicizumab induction after primary hemostasis prevents further bleeding. We suggest that initiating emicizumab therapy is a good choice to prevent further bleeding after critical bleeding events if the patient has not received the drug previously.
