Meconium peritonitis. Pathology, evolution, and diagnosis
Abstract:
The diagnosis of meconium peritonitis has received little attention in the pathology literature. Morphologic features of meconium peritonitis can be confusing to the pathologist unfamiliar with this specific entity, especially in case of extraperitoneal lesions presenting clinically as tumor nodules in the tunica vaginalis. Unfamiliarity with this entity can lead to unnecessary removal of the testis. This paper describes four cases of meconium peritonitis and reviews the literature on the pathology, evolution and diagnostic features of the disease, with emphasis on the healed stage, presenting as a tumor mass in the inguinal canal or tunica vaginalis.
Insights
Meconium peritonitis is often misdiagnosed as testicular tumors due to confusing morphologic features. Pathologists must be aware of its healed presentation to avoid unnecessary testis removal.
Area of Science:
- Pathology
- Surgical Pathology
- Pediatric Pathology
Background:
- Meconium peritonitis diagnosis is underrepresented in pathology literature.
- Morphologic features can be mistaken for other conditions, particularly in extraperitoneal presentations.
- Misdiagnosis can lead to inappropriate surgical intervention, including testis removal.
Observation:
- This paper details four cases of meconium peritonitis.
- It reviews existing literature on the disease's pathology and evolution.
- Emphasis is placed on the healed stage, which can mimic tumor masses.
Findings:
- Meconium peritonitis presents diagnostic challenges for pathologists unfamiliar with the entity.
- Extraperitoneal lesions and healed stages are particularly confusing.
- The condition can present as tumor nodules in the tunica vaginalis or inguinal canal.
Implications:
- Increased pathologist awareness of meconium peritonitis is crucial.
- Accurate diagnosis can prevent unnecessary orchiectomy (testis removal).
- Understanding the healed stage aids in correct identification and management.
