collagenous fibroma

collagenous fibroma

A rare benign, well-circumscribed tumour, usually measuring 1–3 cm, which is more common in males in their 50s to 70s. It is predominantly peripheral and favours the arm, shoulder, neck and other sites; if adjacent to bone, it causes erosion.

Clinical findings
Patients present with a painless subcutaneous mass; one-fourth of cases involve skeletal muscle.

Management
Local excision.

The differential diagnoses6 that should be considered with CFPTs are desmoid tumours, solitary fibrous tumour, desmoplastic fibroblastoma, calcifying aponeurotic fibroma, collagenous fibroma and other sub categories of inflammatory pseudotumours (focal myositis, plasma cell granuloma, inflammatory myofibroblastic tumour etc).6 The diagnosis of CFPT requires clinical exclusion of neoplasms and absence of active infectious processes.

In 1996, it was renamed as collagenous fibroma, which seemed more appropriate to describe its histological features and reflect its benign prognosis.
