A rare case of precoccygeal endometriosis

BACKGROUND: Endometriosis is commonly identified in the abdomen, specifically the ovaries, adnexa, and fallopian tubes, and sometimes in more distant areas; precoccygeal endometriosis is an extremely rare phenomenon. CASE: We present a case involving a 44-year-old woman diagnosed and treated for precoccygeal endometriosis. She underwent laparotomy, extensive lysis of pelvic adhesions, and resection of a 2.5-cm midline precoccygeal mass. After surgical excision of the precoccygeal endometriosis, the patient recovered without incident. CONCLUSION: Precoccygeal endometriosis is a very rare diagnosis.
