Sixty cases of uterine adenomatoid tumors (ATs) are reported. All except four were incidental findings in hysterectomy specimens, three of these being discovered preoperatively as large multicystic tumors. ATs were classified into two distinctive macroscopic patterns: small, solid tumors and large, cystic ones. The 56 small, solid ATs ranged from 0.2 to 3.5 cm, (average 2.1 cm); 48 were nodular and 8 diffuse. The four large, cystic tumors ranged from 7 to 10 cm. Inflammation occurred in 65% of the tumors, and a smooth muscle reaction, identified by an increased Ki-67 index, was present in most cases. Both types were histologically similar except for the presence of short papillae in cystic tumors, which also showed serosal involvement. Both were immunoreactive for cytokeratins, calretinin, HMBE-1, and vimentin. Estrogen and progesterone nuclear receptors and EMA were negative. These tumors represent a spectrum ranging from small and solid to large and cystic ATs in the female genital tract, whereas outside the genital tract they are morphologically similar to multicystic mesothelioma. Although a reactive origin for ATs often seems plausible, especially when inflammation is present, their neoplastic nature should not be ignored.

Mesonephric adenocarcinoma of the uterine corpus: CD10 expression as evidence of mesonephric differentiation.

Mesonephric (wolffian) neoplasms of the female genital tract are infrequent and found in sites where embryonic remnants of wolffian origin are usually detected, such as the uterine cervix, broad ligament, mesosalpinx, and ovary. Their diagnosis is difficult because of the absence of specific immunohistochemical markers for mesonephric derivatives. We present the first report of adenocarcinoma of mesonephric type arising as a purely myometrial mass without endometrial or cervical involvement in the uterine corpus of a 33-year-old woman. The tumor showed a combination of patterns, with retiform areas, ductal foci, and small tubules with eosinophilic secretion, which merged with solid sheets of cells with a sarcomatoid appearance. Immunohistochemically, neoplastic cells were diffusely positive for cytokeratin 7, epithelial membrane antigen, and CD15 and focally positive for BerEP4 and vimentin. A hitherto unreported feature was the positivity for CD10 in neoplastic cells, which was also present in a large number of control tissues obtained from male mesonephric derivatives and female mesonephric remnants and tumors. Furthermore, CD10 was negative in controls from müllerian epithelia of the female genital tract and in their corresponding tumors. Therefore, the expression of CD10 by mesonephric remnants may be useful in establishing the diagnosis of tumors with mesonephric differentiation.

Dehydrogesterone versus vaginal progesterone in the treatment of the endometrial luteal phase deficiency

Juan Balasch; Juan A. Vanrell; Manuel Márquez; Ignacio Burzaco; Jesús González-Merlo

Forty-four infertile patients with inadequate luteal phase histologically documented in at least two separate cycles and normal plasma levels of progesterone (P), estradiol (E2), and prolactin (PRL) were entered into treatment plans on a random basis involving at least 3 months of each of the following: P vaginal suppositories, dehydrogesterone, and no treatment. Success rates were similar for P (62.5%) and dehydrogesterone (68.7%), based on a corrected endometrial defect during the fourth treated cycle or when a term pregnancy was achieved. However, these figures are significantly different (P less than 0.001) when compared with 16.6% of the control group. In ten additional infertile patients with normal luteal function as assessed by endometrial histologic study and hormone measurements, a second biopsy was performed in a consecutive cycle under dehydrogesterone administration. In no case was the normal secretory pattern impaired. It is concluded that (1) both P and dehydrogesterone can be used to advantage in the treatment of luteal phase defects, and (2) therapy with dehydrogesterone does not alter the normal pattern of endometrial secretion.

The endometrial biopsy for diagnosis of luteal phase deficiency

Juan Balasch; Juan A. Vanrell; Montserrat Creus; Manuel Márquez; Jesús González-Merlo

We studied endometrial luteal phase in specimens from 660 biopsies done in 300 patients from our infertility clinic. A minimum of two (240 women) or three (60 women) endometrial biopsy specimens from separate cycles were taken regardless of the previous histologic findings in all patients. Statistical analysis of results by the McNemar and the Cochran Q tests for the significance of changes leads us to conclude that a minimum of two, and even three, endometrial biopsy specimens are needed for diagnosis of luteal phase deficiency.

Dehydrogesterone treatment of endometrial luteal phase deficiency after ovulation induced by clomiphene citrate and human chorionic gonadotropin

Juan Balasch; Juan A. Vanrell; Manuel Márquez; Jesús González-Merlo

Twenty infertile patients being treated with clomiphene citrate (CC) and human chorionic gonadotropin (hCG) for induction of ovulation, with a defective endometrial secretory pattern despite normal plasma levels of progesterone, estradiol, and prolactin, were entered into treatment plans on a random basis involving the following: CC-hCG plus dehydrogesterone (group 1), and CC-hCG (group 2). Success rates were similar in both groups (20% and 30%, respectively), based on a corrected endometrial defect during the second treated cycle. It is concluded that progestational agents are of low therapeutic value in endometrial luteal phase deficiency induced by CC.

Endometrial biopsy inadvertently taken in the cycle of conception.

Juan Balasch; Juan A. Vanrell; Manuel Márquez; Jesús González-Merlo

Endometrial data, plasma progesterone levels and the outcome of pregnancy were analyzed in 22 infertility patients from whom endometrial biopsies had been inadvertently taken in early pregnancy. We found 22.7% (5 cases) of defective endometria in association with normal plasma progesterone levels (available in four patients). Daily plasma progesterone during the first 21st postovulatory days in the cycle of conception is reported in one of our patients. Fourteen of the 22 women delivered normal infants at term, 1 woman had a hydatidiform mole and 7 women aborted (31.8%).

Mesonephric Adenocarcinoma of the Endometrium

Javier Iglesias; Manuel Márquez; Javier Ausin; Lorenzo Casanova; Jesus Gonzalez Merlo

M.H.G., a 64-year-old multipara, was admitted in October 1972 because of a foul smelling bloody discharge of 1 days duration. Menopause occurred at age 57. She was a diabetic under insulin treatment. On physical examination there were several polyps protruding through the cervical os. The uterus was normal in size and the adnexa were negative. The Papanicolaou smear was reported as positive for malignancy, compatible with an adenocarcinoma of the endometrium. Cervical and endometrial biopsies revealed adenomatous cervical polyps and mesonephric adenocarcinoma of the endometrium. Other

The Significance of Luteal Phase Deficiency on Fertility: A Diagnostic and Therapeutic Approach

Juan Balasch; Montserrat Creus; Manuel Márquez; Ignacio Burzaco; Juan A. Vanrell

Luteal phase deficiency, diagnosed by endometrial biopsy, was found in 1 out of 25 control fertile women and in 46 out of 355 infertile patients, a difference that was not significant. It was also found in 19 [corrected] out of 60 patients with early recurrent abortion which was significantly higher than in controls and in infertile patients. Pregnancy outcome was evaluated in treated and untreated groups of patients diagnosed as having luteal phase deficiency. Our data suggest that treatment improved the results of pregnancy in patients with recurrent abortion, but not in infertile patients.
