“…To date, 32 cases of extrauterine, non-ovarian adenomyoma have been reported (46)(47)(48)(49)(50)(51)(52). In patients with extrauterine, non-ovarian adenomyoma, the majority (30/32; 93.8%) of patients were women of childbearing age, and the remaining two (6.3%) were men.…”

Adenomyoma is a benign neoplasm composed of endometrial-type glands, specialized endometrial-type stroma, and well-formed smooth muscle bundles. This tumor typically originates within the uterus, whereas extrauterine adenomyoma is an unusual presentation. The ovary is the most common site of extrauterine adenomyoma. In this study, we describe the clinical and pathological features and immunohistochemical findings of primary ovarian adenomyoma in patients at our Institution. In addition, we provide a thorough review of previously published cases of primary ovarian adenomyoma and clarify their clinicopathological characteristics. The most common clinical presentations of ovarian adenoma were abdominopelvic pain and abnormal menstruation. Imaging features of ovarian adenomyoma varied, showing mixed solid and cystic, solid, or cystic masses. Frequently associated conditions included congenital anomalies of the urinary tract and endometriosis. Although most cases of ovarian adenomyoma exhibit benign histopathological features, we observed one case of endometrioid carcinoma arising in ovarian adenomyoma. Clinical follow-up data indicated that simple excision of the mass is curative for ovarian adenomyoma, but certain patients underwent unnecessary surgical procedures due to lack of awareness of primary ovarian adenomyoma and high index of suspicion for malignancy in patients with solid ovarian masses. Although ovarian adenomyoma is rare, awareness of this tumor type aids pathologists in making correct diagnoses and clinicians in avoiding unwarranted therapeutic procedures.

“…Furthermore, they acquire a contractile phenotype, which allows them to contract the granulation tissue, therefore, minimising its size [21] . They were previously seen in different forms of EM, for example, the peritoneal [11] , rectovaginal, pulmonary [14], and hepatic EM [4] . However, others suggest a smooth muscle metaplasia in EM lesions.…”

“…Many theories have been formulated to clarify the origin of the disease, yet the pathogenesis is still puzzling. While a haematogenous dissemination of endometrial tissue to distant organs can explain EM on the liver [4] or in the urinary tract [5] , a lymphatic dissemination seems more reasonable to explain EM in the regional lymph nodes [6] .…”

In this study, we report about a patient with extra-uterine endometriosis (EM) in the abdominal wall muscle with evident metaplasia based on the abundant alpha smooth muscle actin (ASMA)-expressing myofibroblasts. Laparotomy excision of the abdominal wall EM was done following ultrasonographic evidence of a hypodense swelling in the right rectus abdominis, which was confirmed by MRI. Immunohistochemistry staining for ASMA and collagen I was done, with the results confirming that endometriotic stromal cells expressed both. Anterior abdominal wall endometriosis was suspected because of the patient's history of recurrent EM combined with the cyclic nature of symptoms. MRI is useful in determining the extent of the disease. In case of persisting symptoms even under hormonal treatment, surgical excision is mandatory. The expression of both ASMA and collagen I in and around EM lesions supports the notion of the metaplastic process in the course of disease development.

“…The other cases involved multiple sites like medullary cone, liver, bowel, vaginal cuff and pelvic region (see Table 1). [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] We report a case of a 70 years old woman with an extrauterine adenomyoma of the abdominal wall in the context of disseminated malignant disease. …”

An adenomyoma of the uterus is a nodular tumor-like mass of benign endometrial glands, endometrioid stroma and smooth muscle tissue. Extra-uterine adenomyoma is an extremely rare tumor. The majority of the cases described was from ovary and located in the pelvis. We present a case of a 70 years old woman with clinical and radiological suspicious of disseminated malignancy. In the abdominal wall, a 5-cm nodule of larger dimension detected by computed tomography-scan was biopsied for accessibility reasons. The morphological and immunohistochemical features of the biopsy led us to propose the diagnosis of an extrauterine adenomyoma. This article reports the 22 nd case of extrauterine adenomyoma, a rare and poorly understood tumor that could be imagiologically and clinically indistinguishable from a metastasis.
