After initial attempts of small bower transplantations (SBTX), it seem
ed evident that the small bower graft is highly susceptible to rejecti
on and needs a potent immunosuppressive therapy (1). That fact of matt
er remains responsible of the high morbidity after SBTX: a high immuno
suppressive therapy leads to a high risk of infection, bacterial infec
tion just after surgical procedure and viral of fungal infection in th
e late postoperative period. in those cases, the dosage of immunosuppr
essive therapy has to be considerably reduced leading to rejection (2)
. Rejection often induces a dramatic clinical evolution with severe sh
ock. An adequate treatment is to be ordered as soon as possible.
