Recidives of Mycetoma after Amputation in Dakar (Senegal)

: The treatment of fungal mycetoma is essentially surgical. This carcinological-like surgery consists of amputation in case of bone involvement. The recurrences after amputation are rare and address the problem of the operative indication. We report 5 cases of recurrence of fungal black-grain mycetoma after amputation of leg or thigh. Case 1: a 52-year-old patient with a mycetoma of the knee evolving for 8 years. There is no history of surgery. A thigh amputation with ganglion dissection is performed. One year after the surgical procedure, the patient presents a recurrence on the amputation stump and on the lymph node dissection site. An indication of hip disarticulation is made and performed 17 months after amputation. Case 2: a 25-year-old patient who has a black-grain mycetoma of the foot with osteitis evolving since 10 years. A leg amputation was performed. The patient had a recurrence at the popliteal level at 15 months postoperatively. An indication of amputation of the thigh is posed and refused by the patient. Case 3: a30-year-old woman with black-grain mycetoma of the knee with bone involvement for more than 10 years. A thigh amputation was performed and at nine months postoperativeshe presented a recurrence in the amputation stump. She was lost of sight despite the decision of surgical revision. Case 4: a 43-year-old patient operated on his foot and leg mycetoma at least 5 timesbefore amputation in 2000. The recurrence occurred one year after amputation. 18 years after amputation, a new surgical procedure was difficult due to extension of the lesions in the pelvis. Case 5: a 50-year-old female patient operated in Mauritania in 2012 (thigh amputation for mycetoma of the knee). She presented a recurrence on the amputation stump in 2018. An indication of disarticulation of the hip was posed and refused by the patient. These recurrences were testified by to the persistence of grains on the preserved segment. They pose the problem of the level of amputation and therefore of preoperative planning. Good preoperative planning allows optimization of the surgical procedure and avoids certain recurrences.
