Multifocal peritoneal calcifying fibrous tumour: incidental finding at cholecystectomy

Abstract

Calcifying fibrous tumour (CFT) is a benign tumour of elusive aetiology and a potential for local recurrence. Despite its peculiar histological characteristics it can still be confused with interrelated differential diagnosis like inflammatory myofibroblastic tumour (IMT) or solitary fibrous tumours. The clinical differential diagnosis is however much wider. To date seven cases of multiple peritoneal CFTs are on record. The authors present a case discovered incidentally during laparoscopic cholecystectomy, with no previous history and no radiological diagnosis achieved despite having undergone magnetic resonance cholangiopancreatography (MRCP) and normal routine perioperative investigation. The patient is disease-free 12 months after diagnosis. The case report is followed by a detailed literature review.

Recurrent pleural effusion in a young woman: calcifying fibrous tumour of the pleura

“…Histologically, it is characterised by a non-encapsulated, well-circumscribed mass, containing dense hyalinised collagen, bland spindle cells, lymphoplasmacytic infiltrates and psammoma bodies, or dystrophic calcifications 3. It was first described by Rosenthal and Abdul-Karim in 1988 4.…”

“…It was first described by Rosenthal and Abdul-Karim in 1988 4. CFT of the pleura is quite rare, with a total of 13 reported cases in the literature 3. In young women, recurrent pleural effusions often have more common aetiologies.…”
