Introduction: Formed through the ingestion of hair (trichophagy - often associated with trichotillomania), trichobezoars form slowly and gradually in the stomach. Sometimes they can extend up to the initial portions of the small intestine, giving rise to a condition first described in 1968 as "Rapunzel syndrome". Objectives: To expose to the medical society an atypical picture of tricobezoar. Methodology: Data collection in electronic medical records. [ABSTRACT FROM AUTHOR]

Pneumoperitoneum is a cause of acute surgical abdome, in which the main etiology is the perforation of hollow viscera of the gastrointestinal tract. However, 10% of cases are due to factors not related to perforated viscera. These cases are known as spontaneous pneumoperitoneum, and the main etiology is the peritonitis caused by gas-producing bacteria. This article aims to report a case of spontaneous pneumoperitoneum, a rare entity in the emergency surgery department, attended at the North of Paraná Hospital (HONPAR). [ABSTRACT FROM AUTHOR]

The Spontaneous hematoma of the rectus abdominis muscle is a rare condition -1 / 10,000 of all urgencies - caused by the accumulation of blood in its own muscular sheath due to the rupture of the epigastric vessels or injury of the musculature itself. The present study aims to report a rare case of spontaneous hematoma of the rectus abdominis muscle and to discuss its possible clinical applications. This article reports a case of a 47-year-old woman who was admitted at Regional Public Hospital of Betim Osvaldo Rezende Franco (HPRB) presenting severe abdominal pain and epigastric ecchymosis with hematoma findings in the sheath of the rectus abdominis muscle at imaging examinations. The patient was submitted to conventional treatment after computed tomography of the upper abdomen evidenced the condition. Therefore, it is important to recognize the clinical picture in clinical practice, since its similarity with other acute abdominal conditions can lead to unnecessary surgical interventions.
