Background:
Benign multicystic mesothelioma is a rare pathology. Few cases are reported in the medical literature and acute presentation is extremely uncommon.
Case Presentation:
We describe an acute clinical presentation of the neoplasm that revealed itself with signs and symptoms attributable to acute appendicitis in a 41-year-old white man. Abdominal echography and computed tomography scans demonstrated the presence of a mass in direct contiguity with cecal fundus, but diagnosis remained unclear. Our patient underwent surgery and complete removal of the neoplasm. Only a definitive histological examination defined the nature of the lesion. No signs of relapse were demonstrated 1 year after the operation.
Conclusions:
We showed that an acute presentation of a benign neoplasm represents a diagnostic and therapeutic challenge for the surgeon, because of the difficult differential diagnosis that acute presentation can sometimes pose and the trouble that an emergence treatment can imply.
Insights
Benign multicystic mesothelioma, a rare condition, can mimic acute appendicitis. Surgical removal and histological examination confirmed the diagnosis, with no recurrence after one year.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Benign multicystic mesothelioma is an exceptionally rare neoplasm.
- Acute presentations of this benign tumor are seldom documented in medical literature.
Observation:
- A 41-year-old male presented with symptoms mimicking acute appendicitis.
- Imaging revealed a mass near the cecum, but the diagnosis remained uncertain.
- The patient underwent surgical excision of the mass.
Findings:
- Definitive diagnosis was established solely through histological examination post-surgery.
- The neoplasm was confirmed as benign multicystic mesothelioma.
- No signs of disease recurrence were observed one year post-operation.
Implications:
- Acute presentations of benign neoplasms pose significant diagnostic and therapeutic challenges.
- Accurate differential diagnosis is crucial for appropriate emergent treatment.
- Surgical intervention followed by histological analysis is key for definitive management.
