RESUMO
Introduction: Gender incongruence (GI) is characterized by a marked and persistent incongruence between an individual's experienced gender and assigned sex, which often leads to a desire to "transition" and a demand for medical treatments. Dissociative identity disorder and partial dissociative identity disorder (PDID) are poorly known mental disorders whose clinical presentation can be confused with GI. Aims: To provide a case report of a patient with PDID and GI who required treatment for GI. Methods: A case report and follow-up were described. Results: The case report describes a person suffering from PDID and GI and asked for hormonal treatment for GI. In view of the complexity of the case, it was decided to start a follow-up to investigate the gender experience of the different personalities. After 4 months of follow-up, the symptomatology changed, and the patient waived treatment for GI and continued psychotherapeutic treatment for PDID. Conclusion: Our case report shows the complexity of providing treatment for patient with PDID and GI.
