“The Habit Doesn’t Make the Monk” Dissecting Leiomyoma: Report of Two Cases and Literature Review

We report one case of dissecting leiomyoma and one case of cotyledonoid dissecting leiomyoma.
Patients were hospitalized for the management of gynecologic bleeding and abdominal pain. The preoperative assessment revealed heterogeneous, fast-growing, possibly malignant, uterine masses.
Non-conservative treatment by hysterectomy was performed in both cases. Histopathology of the surgical specimens revealed intramyometrial lesions with dense cellular proliferation, without serous invasion, compatible with dissecting leiomyomas.
We review here the literature and discuss the clinical, radiological and histological aspects of these entities, which can mimic malignant lesions.
