Reconstruction of large truncal defects post-malignant tumor excision using triple rhomboid flaps

The reconstruction of large defect after skin malignant tumor excision is a challenge in dermatologic surgery and reconstructive surgery. This study describes the use of triple rhomboid flaps for reconstruction of large truncal defects after excision of malignant skin tumors.The research aims to present an accessible and efficacious method for reconstructing large truncal defects using triple rhomboid flaps.

Between April 2023 and June 2025, nine patients with large skin malignant tumors in the trunk, with dimensions ranging from 5×5 cm to 17×15 cm, were treated at our hospital. We use triple rhomboid flaps to reconstruct the defects.

No major postoperative complications were seen. All flaps survived, and incisions healed in a single phase. Both medical professionals and patients expressed satisfaction with the results.

In this small retrospective case series, the triple rhomboid flap appeared to be a feasible, practical, and easy-to-perform reconstructive strategy for selected large truncal defects after malignant skin tumor excision. Its simple design and straightforward operative procedure may make it a useful option for dermatologic surgeons, particularly in settings where complex microsurgical reconstruction is not routinely available. Further studies with larger cohorts, longer follow-up, and comparative designs are needed to validate its indications, safety, and long-term outcomes.
