Hereditary angioneurotic oedema is a rare complement-related disorder (C1-esterase-inhibitor deficiency) characterised by recurrent episodic swelling of the limbs, face, gastrointestinal tract, or airways. The mortality rate of the unrecognised disorder is 30 per cent, mainly due to airway obstruction. Two female patients (aged 29 and 61 years) with proven disease were studied by ultrasonography while they suffered from acute abdominal pain: Ultrasound imaging showed a diffuse oedematous but compressible gut wall with reduced bowel motility, distended bowel loops with intraluminal fluid accumulation and free fluid in the peritoneal cavity. The ultrasonographic feature was different from that of other gastrointestinal diseases. In combination with the patient's history, the clinical pattern and the normal routine laboratory findings, abdominal ultrasonography is a suitable tool for early diagnosis of a potentially life-threatening disorder.

The case of a 62-year-old man who presented with acute abdominal pain and a widespread tumor involving the retroperitoneum is described. Three weeks after initial presentation, the patient died suddenly of acute cardiac failure with signs of arrhythmia. Autopsy revealed a disseminated tumor with infiltration of the retroperitoneal fat, as well as nodules in the left testis and the right atrium. The tumor cells were reactive for CD45, vimentin, and chloroacetate esterase, but were unreactive with a broad spectrum of antibodies against myelomonocytic and lymphocytic antigens and with antibodies against tryptase and c-kit (CD117), which are characteristic markers for mast cells. However, the bone marrow exhibited the typical picture of mastocytosis, with disseminated clusters of differentiated spindle-shaped cells that stained strongly for tryptase, c-kit, and chloroacetate esterase. No infiltrates of well-differentiated mastocytosis could be detected in any of the extramedullary tissues investigated. A diagnosis of bone marrow mastocytosis with an associated undifferentiated extramedullary tumor of hemopoietic origin was established. By definition, the extramedullary tumor could not be diagnosed as a granulocytic sarcoma or (differentiated) mastocytoma, but the possibility that a mast cell progenitor could be involved in the evolution of both tumors cannot be ruled out.

C1-esterase inhibitor deficiency is a rare yet classic medical cause of acute abdominal pain mimicking a surgical emergency. A hereditary form and a very rare acquired form of the disease exist, and both give rise to a similar clinical syndrome despite a different pathogenic mechanism. We describe a typical case of acquired C1-esterase inhibitor deficiency in a 65-year-old woman presenting with recurrent acute abdomen and ascites who had undergone two negative surgical interventions before diagnosis was eventually established. Both the diagnostic and therapeutic approach to this rare condition should be known by emergency physicians for two reasons: (1) it may present as an acute abdominal emergency resulting in unnecessary surgical intervention; and (2) it may cause life-threatening upper airway obstruction as a result of laryngeal oedema.

Accurate and timely diagnostics of acute abdominal pain, a common emergency, is crucial in decreasing unnecessary surgical interventions. We present the case of a patient, Xh. M. aged 21, transported to emergency after being wakened from sleep by severe, acute abdominal pain. The pain was non-radiating, colic, and associated with flatulence, nausea and vomiting. The family history was negative regarding Angioedema, which decreases but does not exclude the possible appearance of hereditary Angioedema. All laboratory and imaging findings were normal, besides the low levels of C4 complement component were 4.56 mg/dl (normal values 10-40), functional C1-esterase INH was 10.29% (normal values 80-130) C1-estrease inhibitor (protein) 4.58 mg/dl (normal values 16-33), indicating HAE typ I. Regardless of negative medical history in the family of hereditary angioedema, de novo mutation most probably led to her being the first case in the family. The case we have presented confirms the need to include hereditary angioedema as a differential diagnostic possibility in patients with acute abdominal pain, even more so as timely and precise diagnostics enable avoidance of unnecessary surgical interventions.
