“…Few cases of uterus-like mass involving ovary, fallopian tube, cervix, small bowel mesentery, obturator lymph node, colon and scrotum have been reported [3,4]. To the best of my knowledge, only six cases of the uterus-like mass of broad ligament have been published in the literature and this is the seventh case [1,3,[5][6][7][8]. (Table 1)…”

The uterus-like mass (ULM) is an anatomical entity first described in the ovary and thereafter, reported in several locations of the pelvis and abdominal cavity including broad ligament, greater omentum, cervix, small intestine, mesentery and conus medullaris. It is characterized by a miniature uterus comprising a smooth muscle wall lined by endometrium; thus, delineating a uterus-like anatomical structure. A 46-year-old lady presented with swelling in the abdomen. Imaging studies showed a thick walled cystic lesion in the pelvis and histopathology revealed a uterus like mass reminiscent of uterine morphology with its characteristic inner endometrium and outer smooth muscle. This entity is very uncommon with only few cases reported in literature. This case is being highlighted for its rarity and to discuss the possible theories for origin of this uncommon condition.

“…[1–45] The most common location for a single mass was in the pelvic cavity (37 cases), including 12 cases in adnexa [7–15,27,44] and 7 cases in broad ligament. [16–22] There were 9 cases of single mass outside the pelvis, [29–33,35,36,38,43] of which 3 cases occurred in the liver. [29,30,43] There are 10 cases of multiple foci.…”

“…[1] The extrauterine adenomyoma is rare, and it was first reported by Rubenstein and Kurzon in 1952. [2] So far, the reported sites of extrauterine adenomyoma are mainly in the pelvic cavity, such as pararectal space, [1,[3][4][5][6] ovary, [1,[7][8][9][10][11][12][13][14][15] broad ligament, [16][17][18][19][20][21][22][23] the round ligament, [1,2,24] paraovarian, [10,[25][26][27] parametrial, [10] and pelvic wall. [28] It is extremely rare outside the pelvic cavity such as liver, [29,30] upper abdomen, [6] inguinal region, [31,32] colon, [33,34] appendix, [35] small bowel mesentery, [36,37] and retroperitoneal space.…”

Rationale: The extrauterine adenomyoma is rare and it is extremely rare outside the pelvic cavity. Herein, we reported the first case of a single extrauterine adenomyoma occurring in the lesser omentum.Patients concerns: This case involved a 55-year-old woman who had undergone subtotal gastrectomy and omentectomy for gastric carcinoma. During postoperational pathological examination, 1 lymph node-like mass was coincidentally found in the lesser omentum. The patient had a history of hysterectomy for uterine leiomyoma 8 years ago.Diagnoses: The resected 17 "lymph nodes" from the lesser omentum were routinely checked for possible metastasis of gastric carcinoma. One of lymph node-like mass was microscopically showed that it was composed of benign smooth muscle components, endometrial glands and stroma by HE staining. Therefore, adenomyoma was initially considered.Interventions: The lymph node-like mass was removed together with the lesser omentum during the subtotal gastrectomy and omentectomy for gastric carcinoma. No special intervention was performed for the adenomyoma.Outcomes: Immunohistochemical staining confirmed that smooth muscle tissue was diffusely and strongly positive for Desmin, smooth muscle actin, estrogen receptor, and progesterone receptor, and negative for CD117, Dog-1, S100, and CD34. Endometrial glands and stroma were positive for estrogen receptor and progesterone receptor, and the endometrium interstitium was also positive for CD10. The final diagnosis of extrauterine adenomyoma occurring in the lesser omentum was established.Lessons: So far, to the best of our knowledge, total 53 cases of extrauterine adenomyoma have been reported in 45 English reports. The most common location for a single mass was pelvic cavity (37 cases), but rarely outside the pelvic cavity. This is the first case of a single extrauterine adenomyoma occurring in the lesser omentum.Abbreviations: CD10 = common acute lymphoblastic leukemia antigen, CD117 = stem cell growth factor receptor, CD34 = hematopoietic progenitor cell antigen, ER = estrogen receptor, PR = progesterone receptor, SMA = smooth muscle actin.

“…Other reports have detailed masses ranging from 1 to 20 cm in size, with cystic components, adenomyosis, or large cavities lined with endometrial tissue. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] However, this is the first report of concurrent involvement of endometrioid adenocarcinoma in both an extrauterine adenomyoma and uterine fundus.…”
