Bilobed flap reconstruction after en-bloc removal of solitary fibrous tumor of the lacrimal sac

Purpose: To report a rare case of a solitary fibrous tumor (SFT) of the lacrimal sac and discuss considerations for management of similar cases. Observations: We present the case of a 41-year-old woman who presented with a primary lacrimal sac SFT for which she underwent en-bloc surgical resection. We discuss management options for SFTs and our surgical approach for this case: bilobed flap reconstruction of the medial canthus and inferior orbit. Conclusions: We present an uncommon presentation of a rare tumor and a successful one-stage reconstruction with a bilobed flap.
