Examination

  • • Soft, lobulated, fluctuant, slip sign positive, non-tender, freely mobile

Red flags

  • • Rapid growth, pain, induration, deep/intramuscular location, size >5 cm — exclude liposarcoma

Differential diagnosis

Diagnosis

  • • Clinical ± imaging; histopathology after excision

Initial treatment / management

  • • Observation if asymptomatic, small, classical
  • • Excision if symptomatic, cosmetic, or atypical features

Prescription examples

Follow-up advice

  • • Suture removal 7–10 d; ensure histopathology reviewed

Patient counselling

Clinical pearls
