Perianal Reconstruction after Endometrioid Adenocarcinoma Excision using Inferior Gluteal Artery Perforator Flap

Background: There are rare cases of endometrioid adenocarcinoma emerging from endometriosis of the uterine cervix in premenopausal woman. Methods: We describe here a patient with this condition, presented with large perianal tumor, with a long-standing history of perianal endometriosis in episiotomy scar. This was initially evaluated with a Magnetic Resonance Imaging (MRI) and the diagnosis was confirmed by biopsy. Result: The evolution of more wide excision surgery resulted in an increase in large defects of the perineal and perianal region. The inferior gluteal artery perforator (IGAP) flap was chosen as the best in a functional and aesthetic solution in this case. Conclusion: The main recent advance in perianal reconstruction is the progress in perforator flap surgery. Reconstruction of perianal defects has functional and aesthetic considerations. Perianal reconstruction is very rare and review articles or larger case series are absent, hence only case reports have been published
