AbstractThe etiology of chronic abdominal pain can be elusive. The diagnostic workup, therefore, often includes superfluous and expensive tests, as well as invasive procedures which do not contribute to the final diagnosis. Studies have shown that some patients suffer from prolonged pain in the abdominal wall and often are misdiagnosed and treated as having a visceral source for their complaints. The abdominal wall might be considered to be an unlikely source of prolonged abdominal pain, but one study reported that in 15% of patients with prolonged, nonspecific abdominal pain, the abdominal wall was the source of the complaint. Abdominal pain resulting from cutaneous nerve entrapment has not been reported previously in children and adolescents, nor has nerve entrapment been reported as a complication of oral contraceptives. The case of a 15-year-old girl who came to the hospital emergency room with abdominal pain of 3 months duration is reported. A comprehensive workup had not established a specific cause for the pain. On the basis of the clinical findings, the possibility of a cutaneous nerve entrapment was suggested. After the involved cutaneous nerve was selectively blocked by subcutaneous infiltration, the pain disappeared immediately and completely. Recognition of this apparently unusual condition can lead to gratifying results. It is proposed that oral contraceptive therapy may have caused changes in the abdominal wall which led to nerve entrapment and the ensuing severe, prolonged pain.
