Introduction: Histoplasmosis is an opportu­nistic granulomatous fungal infection. Peritoneal histoplasmosis (PH) is a rare form of dissem­inated histoplasmosis (DH).Case description: A 44-year-old male pa­tient with history of HIV infection, systemic lupus erythematosus with lupus nephritis, and chronic kidney disease on peritoneal dialysis, presented with recurrent ascites without clear etiology in the serial study of ascitic fluid. Con­trast computed tomography of the abdomen showed a nonspecific peritoneal nodule, for which laparoscopy and biopsy were performed, identifying Histoplasma capsulatum infection. The subject received 15 days of in-hospital treatment with amphotericin B deoxycholate with good evolution, no recurrence of ascites, and indefinite outpatient management with itraconazole.Discussion: The first case of PH was described in 1970 but this is the first case reported in Co­lombia. Most cases of PH have been associated with peritoneal dialysis. Its diagnosis is based on the study of ascitic fluid and its treatment follows the guidelines of other forms DH.Conclusions: PH is a rare entity that requires high clinical suspicion, especially in immuno­compromised patients.

Introduction: De Garengeot hernia is an entity mainly diagnosed intraoperatively. It is more frequently observed in women and is defined as the presence of the vermiform appendix inside to femoral hernia. Most femoral hernias are identified based on clinical diagnosis, but diagnostic imaging is necessary for confirmation. Ultrasound, for example, is a valuable tool to characterize the anatomy of the hernia and its content, and to establish surgical planning. Case presentation: A 75-year-old woman attended the general surgery department of a high complexity hospital in Bogotá, Colombia, due to a painful mass in the right inguinal region. The initial ultrasound study showed a femoral hernia containing the incarcerated appendix and periappendiceal fluid in the hernial sac. The patient developed chronic appendiceal inflammation, so she underwent femoral hernia repair with mesh and appendectomy without complications, achieving a satisfactory recovery. Conclusion: Clinical examination may be sufficient to confirm the presence of a hernia in a large number of cases when the diagnostic approach involves the search of inguinal masses with pain. However, to facilitate surgical planning, diagnostic imaging, especially ultrasound with high resolution transducers, is the primary tool to characterize the type of hernia and the contents of the hernial sac.
