“…The main tumor in our case was exceptionally large about 15 cm in diameter and weighed about 1000 g. In the literature, 11 patient age at the time of diagnosis ranges from 26 to 55 years (with a median of 41 years). Only two patients in the previous reports, 11,12 were below 30 years of age, and those patients were 25 and 26 years‐old, the same as the present patient.…”

“…Pathologically, there is now agreement that it represents a unique variant of benign mesothelioma largely restricted to the genital region [14]. Adenomatoid tumors of the fallopian tube are usually found as incidental small (≤2 cm) lesions within the wall of the tube [18]. However, in the present case the tumor was relatively large, and the preoperative diagnosis was pedunculated myoma or solid adnexal tumor.…”

“…Correct diagnosis of fallopian tube tumor was established after laparoscopic observation. Although laparoscopic management of adenomatoid tumor of the fallopian tube has not been reported, surgical intervention itself was not difficult by laparoscopy, as adenomatoid tumor of the fallopian tube is usually well circumscribed [18]. Therefore, knowledge about the existence of this type of tumor contributes to the consideration of the surgical approach to solid/predominantly solid adnexal tumors for successful laparoscopic management.…”

Fourteen cases of laparoscopically treated solid/ predominantly solid nonepithelial adnexal tumors are presented. Unilateral salpingo-oophorectomy was performed in seven cases [three fibromas, one thecoma, one strumal carcinoid, one Sertoli-Leydig cell tumor (G2), and one dysgerminoma], including a 21-year-old patient with fibroma with adnexal torsion. A 26-year-old patient with fibroma was treated by tumorectomy. Laparoscopicassisted vaginal hysterectomy and bilateral salpingooophorectomy were done in five cases [three thecomas, one adult-type granulosa cell tumor, one Sertoli-Leydig cell tumor (G2)], including a 52-year-old patient with thecoma complicated by torsion. In a case of adenomatoid tumor of the fallopian tube, unilateral salpingectomy was done. Adjuvant platinum-based chemotherapy was added in a case of dysgerminoma, and there has been no sign of recurrence after 3 years.

“…Thus, we strongly suspect that ATs are significantly under-diagnosed, probably due to lacking familiarity with these uncommon tumors and their usually bland histology. The majority of ATs occur as small solitary lesions, but some may present as large tumors [12] and up to 10-20% of the uterine ATs were reportedly multifocal [25,26]. On the other hand, most of ATs of the male genital tract (∼90%) present as clinical masses that prompt surgical intervention.…”

Adenomatoid tumors of the female and male genital tract. A comparative clinicopathologic and immunohistochemical analysis of 47 cases emphasizing their site-specific morphologic diversity

Adenomatoid tumors (ATs) are uncommon benign mesothelial tumors with a predilection for the genital tract. We reviewed 47 ATs diagnosed at our institutions during 10-year period. Thirty tumors (64%) originated in the female (21 uterine, 8 tubal, and 1 ovarian) and 17 (36%) in the male (9 epididymal and 8 testicular) genital tract. The median age for females and males was 47.5 and 51 years, respectively. While 83% of tumors in females were incidental findings in resections for unrelated diseases, 94% of male lesions presented as clinical masses leading to surgery. The median size was 2, 1, and 0.5 cm for uterine, epididymo-testicular, and tubo-ovarian lesions, respectively. Architecturally, the microcystic/angiomatoid pattern was the most frequent (32/47; 68%), followed by combined microcystic/trabecular (26/47; 55%) and retiform/adenoid (15/47; 32%) pattern. The trabecular/solid (6%) and macrocystic (4%) patterns were uncommon. However, 57% of cases revealed ≥2 growth patterns. Taken by anatomic site, 20 of 21 uterine cases were at least focally microcystic but none was retiform. In contrast, the retiform pattern dominated in male genital tract tumors (12/17; 71%). Immunohistochemistry showed expression of calretinin (36/36) and D2-40 (30/30) and lack of CD34 (0/30) and PAX8 (0/32). GLUT-1 was expressed in 11/11 male genital tract tumors but in none of the microcystic uterine lesions. Estrogen and progesterone receptor expression was weak and focal (two and three uterine cases, respectively). None stained for the androgen receptor. Our study illustrates the great site-specific morphological diversity of ATs emphasizing their wide site-dependent differential diagnosis.

Adenomatoid tumor of the female genital tract

Abstract: Some different results were obtained than those hitherto reported in the literature, such as younger age, frequency of multiple tumors, and fewer cases accompanied by leiomyomas.
