Mucinózny adenokarcinóm (neintestinálneho typu) vzniknutý v zrelom cystickom teratóme vaječníka - kazuistika

Malígna somatická transformácia v zrelom cystickom teratóme je zriedkavý fenomén, pri ktorom vzniká zhubný nádor z diferencovaných tkanivových štruktúr niektorého zo zárodočných listov.

Autori prezentujú prípad 38 - ročnej ženy so zrelým cystickým teratómom oboch vaječníkov a mucinóznym adenokarcinómom vzniknutým z endodermálnej zárodočnej línie v pravom ováriu, ktorý imunohistochemicky vykazoval charakteristiky non-intestinálnej diferenciácie. V čase diagnostiky nádor metastázoval do panvových a retroperitoneálnych lymfatických uzlín.

Pacientka bola liečená troma líniami chemoterapie a po 15 mesiacoch od stanovenia diagnózy zomrela za príznakov progresie vo forme masívnej nádorovej propagácie do retroperitoneálnych, mediastinálnych a krčných lymfatických uzlín, infiltrácie retroperitonea a duodena a peritoneálneho rozsevu.

Malígna somatická transformácia v zrelom cystickom teratóme je spojená so zlou prognózou. Najdôležitejším prognostickým faktorom je štádium v čase stanovenia diagnózy.
