Nowadays, it is becoming increasingly difficult to clearly classify the issues associated with the phenomenon of gender dysphoria due to the fact that one identifies oneself in the context of increasingly fluid categories of gender identity - an intrinsic sense of being a woman or a man. The authors present a woman, whose internal problems connected with her sexuality and incomplete identification with the role attributed to her gender originate from her family history. Long-lasting, traumatic experiences of incestuous abuse and violence on the part of close relatives disturbed her development in many areas of personality and functioning. The aim of the study was to verify the hypothesis of the existence of gender identity disorder accompanied by depressive disorders. In addition to the medical history, the study of patient's problems included the following diagnostic tools: the Minesocki Multiphasic Personality Inventory (MMPI) and the Rorschach Inkblot Test in a CSR Exner system (TPA). The study revealed that as for sexual identification, the patient unambiguously identifies herself as a woman. Her behaviour to become like a man does not deny her sex, or even involve a temporary need of belonging to the opposite sex. It should be interpreted in the broader context of her traumatic experiences, not just sexual, but also concerning different aspects of a female gender role.
