Zusammenfassung
Myxoide Leiomyomata stellen eine seltene Variante uteriner Leiomyome dar. Sie sind durch eine myxoide Beschaffenheit, fehlende mitotische Aktivität und einen myogenen Phänotyp charakterisiert. Im vorliegenden Fall einer 38-jährigen Patientin zeigte sich eine zystische Lymphangiom-ähnliche Komponente, die von endothelartigen Zellen mit positiver CD 34-, CD 31- und Faktor VIII-Immunreaktivität ausgekleidet waren. Aufgrund des fehlenden invasiven Wachstums konnte ein myxoides Leiomyosarkom als wichtigste Differenzialdiagnose ausgeschlossen werden.
Summary
Myxoid leiomyomas of the uterus are uncommon. They are characterised by a myxoid stroma, no mitotic activity and a myogenic phenotype. We present a case with focal lymphangioma-like pattern. The solid compartiment showed positive immunoreactivity with muscular markers and but no CD 34-immunostaining. Contrary, the endothelial-like cells of the cystic part were positive with antibodies against CD 34, CD 31 and factor VIII, indicating vascular differentiation. The lack of infiltrative growth patterns excluded myxoid leiomyosarcoma as the major differenzial diagnosis.
