ABSTRACT
Intranodal schawnomas are extremely rare. Just a few cases have been described before. Clinical presentation comprises not only symptomatic mass in several anatomical body parts, but also, they can be found during analysis of surgical specimens resected for other reasons. The report is based on the case of an 80-year-old patient who underwent to right hemicolectomy for an adenocarcinoma. The histopathologic analysis revealed one mesenteric intranodal schwannoma in the surgical specimen. The diagnosis was confirmed by immunohistochemistry with positive result for vimentin and S100 protein. Less than 12 cases have been reported in the literature before. The findings pointed out our patient as, one of these few reported with such diagnosis.
ABSTRACT
Mekel's diverticulum is a gastrointestinal malformation. Occurs in one of every 40 patients. It is usually asymptomatic whereas complications can be developed in 2% to 4%. The report is based on a 41-year old male, who attended to emergency, complaining of right lower quadrant abdominal pain. Blood tests showed high level of inflammatory markers. With acute appendicitis as presumptive diagnosis, laparoscopy was performed. The intraoperative findings were: a perforated Mekel's diverticulum with normal cecal appendix. Mechanical diverticular resection was made. The patient was successfully recovered from surgery. Histopathology examination showed: Meckel's diverticulum perforated with acute inflammation and neuroendocrine tumor (G1) pT1. Mekel's diverticulum is rarely affected by inflammatory complications and just few cases are associated with tumors. However, has ever been described before, coexisting both situations, being our patient the first reported with this exceptional clinical presentation, and treated successfully by laparoscopic approach.
ABSTRACT
Endometriosis is a painful disorder characterized by endometrial tissue outside the uterine cavity. It usually affects the pelvis, but in rare cases it might extend to other parts of the body. The report is based on a case of a 39-year-old woman, who presented symptoms of acute appendicitis and diagnosis confirmed with ultrasonography and a computed tomography scan procedures. Laparoscopic appendicectomy was performed. After entering the abdominal cavity, hemoperitoneum was discovered with no associated pelvic or abdominal lesions. Biopsy confirmed acute appendicitis with endometrial glands and stroma infiltrating its muscular tissue. Patient recovered without complications and was discharged 48 h after surgery. The appendix is rarely affected by endometrial infiltration. The literature describes an incidence of 0.8%, just a few cases have been associated with acute appendicitis; however, none of them are described to present hemoperitoneum, being our patient the first one reported with such complication.
