RESUMEN
BACKGROUND: A lymphocele or lymphocyst is formed when lymphatic fluid accumulates in a space, following disruption of lymphatic channels. Here, we report a case of a giant lymphocele in a middle-aged female, who underwent Trendelenburg operation (saphenofemoral junction ligation) for varicose veins of her right lower limb. CASE PRESENTATION: A 48-year-old Pakistani Punjabi female presented to the plastic surgery outpatient department with a history of painful, progressive swelling of the right groin and medial aspect of the right thigh for 4 months. After investigation, it was diagnosed as a giant lymphocele. A pedicled gracilis muscle flap was used to reconstruct and obliterate the cavity. There was no recurrence of the swelling. CONCLUSION: Lymphocele is a common complication after extensive vascular surgeries. In the unfortunate case of its development, prompt intervention must be done to prevent its growth and ensuing complications.
