Hysteroscopic treatment of Müllerian duct anomalies

Müllerian duct anomalies are a broad and complex spectrum of abnormalities that are often associated with infertility, obstetric complications as well as gynecological disorders among women of reproductive age. Operative hysteroscopy is the gold standard in the treatment of most of those anomalies amenable to surgical correction. The evidence to date shows an ongoing increase in the release of recommendations in favour of operative hysteroscopic treatment, in concert with the progressive refinement of hysteroscopic technologies and techniques. The aim of this paper was to describe and critically evaluate the role of the currently available hysteroscopic techniques for treating Müllerian duct anomalies, taking into account their indications, feasibility and efficacy as well as their impact on the reproductive outcome. Special attention will be paid to the most recently developed minimally invasive treatments for uterine and vaginal anomalies.

Laparoscopic Modified Vecchietti Technique for Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome: Report of Two Cases

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by uterine aplasia and aplasia of the upper part of the vagina. It presents with primary amenorrhea in a 46, XX individual. In this paper, we report the cases of two patients with MRKH syndrome treated with the laparoscopic modified Vecchietti technique using the optimized new instruments. A neovagina was successfully created in these two patients. This minimally invasive technique offers improvements in terms of operative time, complications, and functionality.

The Utility of Core Needle Biopsy and Fine-Needle Aspiration in the Workup of Tumors of Suspected Müllerian Origin

OBJECTIVES

Core needle biopsy (CNB) and fine-needle aspiration (FNA) for tumors of suspected Müllerian origin may prevent unnecessary laparotomies and allow patients the benefit of neoadjuvant chemotherapy. An assessment of the utility and limitations of CNB/FNA, with incorporation of current immunohistochemistry, is needed.

STUDY DESIGN

Two hundred nineteen female patients with CNB/FNA of the omentum, pelvis, abdomen, adnexa, ovary, uterus, and fallopian tube were identified. From these, 30 consecutive CNB/FNA with corresponding surgical resection were reviewed to assess diagnostic agreement and identify potential diagnostic pitfalls.

RESULTS

The most frequent diagnosis overall was adenocarcinoma (96/219; 43.8%), most commonly adenocarcinoma of gynecologic origin (65/219; 30%). Nondiagnostic or unsatisfactory material was present in a minority of cases (10/219; 5%). In the 30 CNB/FNA cases examined for diagnostic agreement with surgical resection, 24 (80%) had exact or essential agreement with the final diagnosis. Of the 23 cases that were positive and/or suspicious on cytology, 18 (78%) had neoadjuvant chemotherapy or radiation treatment prior to surgical resection.

CONCLUSIONS

The majority of CNB/FNA for tumors of suspected Müllerian origin are diagnostic, correlate with the surgical resection, and contribute to management. A standard diagnostic algorithm is suggested.

Sexual and Psychosocial Functioning in Women with MRKHS after Neovaginoplasty According to Wharton-Sheares-George: A Case Control Study

Background

Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) has a major impact on a woman’s psychological and sexual well-being. In most of the studies that addressed treatment techniques, postoperative sexual function was reported to be satisfactory; however, comparatively few studies have additionally provided an accurate analysis of psychosocial functions in MRKHS patients following different kinds of neovaginal treatment. This study is to evaluate sexual and psychosocial functioning after creation of a neovagina according to Wharton-Sheares-George in women with MRKHS.

Methods

We performed a case-control-study using multiple measures to assess sexual and psychosocial functioning. Ten MRKHS patients and 20 controls of a University hospital and tertiary center for pediatric and adolescent gynecology were assessed. The follow-up assessment comprised 6 standardized questionnaires (Female Sexuality Function Index, FSFI; Patient Health Questionnaire, PHQ; Brief Symptom Inventory, BSI; World Health Organization Quality of Life Assessment, WHOQoL-BREF; Parental Bonding Instrument, PBI; and a German questionnaire on body image). The main outcome measures were sexual function, psychological status, quality of life, body image, and parental bonding styles.

Findings

Sexual function, psychological status (including depressive and somatic symptoms), quality of life, and own-body experience were at least as good in operated MRKHS patients as in controls. In some measures (FSFI, PHQ-15, psychological domain of the WHOQoL-BREF, and BSI Positive Symptom Total), patients scored significantly better than controls. The results of the PBI indicated a close and sustainable mother-daughter-relationship in MRKHS patients.

Conclusions

We found no evidence for an impairment of sexual or psychosocial functioning in patients after neovaginoplasty according to Wharton-Sheares-George. MRKHS may not necessarily compromise sexual and psychological well-being, provided that the syndrome is properly managed by a multidisciplinary team of health professionals.

[Comparison study between Vecchietti's and Davydov's laparoscopic vaginoplasty in Mayer-Rokitansky-Küster-Hauser syndrome]

OBJECTIVE

To compare Vecchietti's and Davydov's laparoscopic techniques for vaginoplasty in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

METHODS

From January 2010 to December 2013, 13 patients underwent the Vecchietti's laparoscopic procedure (Vecchietti group), and 15 patients underwent the Davydov's laparoscopic procedure (Davydov group). Intraoperative parameters and postoperative results were compared.

RESULTS

Both of the two groups were successfully treated. The neovagina in both groups were wide with good elasticity, softness and smoothness. The operation time [(39±7) versus (73±11) minutes], the intraoperative blood loss [(21±6) versus (63±10) ml], the anal exsufflation time after surgery [(19±5) versus (28±6) hours] and the recovery period of body temperature after surgery [(35±10) versus (46±10) hours] of the Vecchietti group were less than those of the Davydov group (all P<0.05). But the neovagina length [(8.8±0.5) versus (9.6±0.5) cm] was shorter and the Female Sexual Function Index scale score [26.8±2.0 versus 28.5±1.7] was lower in the Vecchietti group than those in the Davydov group (all P<0.05). The postoperation hospital duration didn't reached statistical difference between the two groups [(7.5±0.9) versus (7.1±0.7) days, P>0.05]. No intraoperative complication occurred. After surgery, 2 patients were found vaginal polyps and 8 patients were suffered from pain in the Davydov group, while all patients were suffered from pain in the Vecchietti group.

CONCLUSIONS

Both Vecchietti's and Davydov's laparoscopic techniques are simple, safe and effective surgical methods for vaginal reconstruction. In contrast, the Vecchietti's procedure is more time efficient and minimally invasive, while the Davydov's procedure can get less pain, longer vagina and higher sexual satisfaction.

Oestrogen receptor alpha expression in neovaginal tissue of women following modified Abbé-McIndoe technique and in premenopausal women

The aim of the study was to compare the expression of oestrogen receptor alpha (ERα) in neovaginal tissue of patients with vaginal agenesis following neovaginoplasty using regenerated, oxidised cellulose in premenopausal women. A prospective, observational case-control study was performed on eight patients with vaginal agenesis following modified Abbé-McIndoe neovaginoplasty and 10 control premenopausal women following benign gynaecologic surgery. 6F11 monoclonal antibody was used to determine ERα expression in the vaginal mucosa. Quantitative and qualitative evaluations were performed, respectively, in vaginal epithelium and stroma. The thickness of the vaginal epithelium was determined as the vertical distance between the basal layer cells and the apical surface of the superficial layer. The percentage of ERα-expressing cells was higher in the control group, except in the superficial zone of the epithelium. In the stromal tissue, ERα was detected in only one patient from the neovagina group compared with nine women in the control group. The neovagina group had a statistically thinner epithelium. Our study suggests that women with vaginal agenesis following modified Abbé-McIndoe neovaginoplasty using regenerated oxidised, cellulose experience relatively local hypo-oestrogenism in the first year after surgery, with repercussion in vaginal trophism.

Livebirth after uterus transplantation

BACKGROUND

Uterus transplantation is the first available treatment for absolute uterine infertility, which is caused by absence of the uterus or the presence of a non-functional uterus. Eleven human uterus transplantation attempts have been done worldwide but no livebirth has yet been reported.

METHODS

In 2013, a 35-year-old woman with congenital absence of the uterus (Rokitansky syndrome) underwent transplantation of the uterus in Sahlgrenska University Hospital, Gothenburg, Sweden. The uterus was donated from a living, 61-year-old, two-parous woman. In-vitro fertilisation treatment of the recipient and her partner had been done before transplantation, from which 11 embryos were cryopreserved.

FINDINGS

The recipient and the donor had essentially uneventful postoperative recoveries. The recipient's first menstruation occurred 43 days after transplantation and she continued to menstruate at regular intervals of between 26 and 36 days (median 32 days). 1 year after transplantation, the recipient underwent her first single embryo transfer, which resulted in pregnancy. She was then given triple immunosuppression (tacrolimus, azathioprine, and corticosteroids), which was continued throughout pregnancy. She had three episodes of mild rejection, one of which occurred during pregnancy. These episodes were all reversed by corticosteroid treatment. Fetal growth parameters and blood flows of the uterine arteries and umbilical cord were normal throughout pregnancy. The patient was admitted with pre-eclampsia at 31 full weeks and 5 days, and 16 h later a caesarean section was done because of abnormal cardiotocography. A male baby with a normal birthweight for gestational age (1775 g) and with APGAR scores 9, 9, 10 was born.

INTERPRETATION

We describe the first livebirth after uterus transplantation. This report is a proof-of-concept for uterus transplantation as a treatment for uterine factor infertility. Furthermore, the results show the feasibility of live uterus donation, even from a postmenopausal donor.

[Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermal matrix]

OBJECTIVE

To introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.

METHODS

We retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.

RESULTS

The time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.

CONCLUSIONS

Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.

Optimizing the modified laparoscopic Vecchietti procedure

OBJECTIVE

To enhance the modified laparoscopic Vecchietti procedure.

MATERIALS AND METHODS

A case series of five women with Mayer-Rokitansky-Küster-Hauser syndrome at the Department of Obstetrics and Gynecology, King Abdulaziz University Hospital, Jeddah, Saudi Arabia underwent the modified laparoscopic Vecchietti procedure with intraperitoneal placement of sutures. This involved perforation of the vaginal dimple by a straight thread guide with two threads attached to the olive followed by pulling the two threads intra-peritoneally and through the abdominal wall to the traction device by grasping instruments under laparoscopic control.

RESULTS

Intraperitoneal placement of the sutures was easily done without complications in all five women. The operative time was 50 ± 10 (mean ± SD) minutes. After five postoperative days, the average vaginal length was seven to 7.5 cm. Two women were able to have vaginal intercourse without problems. After six months to one year of follow up, the vaginal length was at least ten cm and no postoperative complications occurred.

CONCLUSIONS

Intraperitoneal placement of sutures makes the modified laparoscopic Vecchietti procedure easy and appealing. Furthermore, it avoids potential damage to the vital structures at the pelvic side walls.

An unusual cause of acute scrotum in a child

Acute non-traumatic scrotal pain in children, commonly due to a torted testicular appendage (hydatid of Morgagni) or torted epididymal appendage is well described. These vestigial embryonal duct remnants are of Müllerian and Wolffian duct origin respectively. Very rarely, the other infrequently encountered Wolffian duct remnants known as the paradidymis or organ of Giraldés and the superior and inferior aberrant ducts known as the organs of Haller can become torted. We describe the presentation, management and diagnosis of a torted embryonal remnant arising from the distal spermatic cord.

Mayer-Rokitansky-Kuster-Hauser syndrome: complications, diagnosis and possible treatment options: a review

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a disorder in women that presents as Mullerian agenesis. These patients present internal genitalia abnormalities that include the absence of a uterus and the upper two-thirds of the vagina. In this review, current diagnostic methods, accompanying complications (congenital and psychological) and non-surgical and surgical treatments are summarized. Ultrasound and MRI have been the most documented options in MRKH syndrome diagnosis. Many women with MRKH syndrome have renal, skeletal, hearing or cardiac congenital anomalies and increased levels of psychological distress. Non-surgical interventions can be used to create a sexually functional neovagina through vaginal dilation, and surgical interventions provide alternate methods of creating a neovagina. Additionally, vaginal tissue engineering and gene therapy might provide more effective approaches in solving MRKH syndrome.

And god created woman? The link between female sexuality and the mother-daughter relationship in Mayer-Rokitansky-Kuster-Hauser syndrome in adolescents

The authors' clinical experience with young girls with Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH), who are facing the often hastily suggested, and accepted, surgical treatment of vaginal reconstruction brings new light to the question of female sexuality and its specific modes of access: its traumatic aspects, the mother-daughter conflict of ambivalence and the associated risk of depression, as well as the importance of the relational factor in the construction of bodily interiority.

Tissue-engineered autologous vaginal organs in patients: a pilot cohort study

BACKGROUND

Several disorders might require vaginal reconstruction, such as congenital abnormalities, injury, or cancer. Reconstructive techniques for which non-vaginal tissue is used can be associated with complications. We assessed the use of engineered vaginal organs in four patients with vaginal aplasia caused by Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS).

METHODS

We invited to participate four consecutive patients who presented over a 3-year period with congenital vaginal aplasia due to MRKHS. Patients were aged 13-18 years. We obtained a vulvar biopsy of autologous tissue from every patient. We cultured, expanded, and seeded epithelial and muscle cells onto biodegradable scaffolds. The organs were constructed and allowed to mature in an incubator in a facility approved for human-tissue manufacturing. We used a perineal approach to surgically implant these organs. We recorded history, physical examination, vaginoscopy, serial tissue biopsies, MRIs, and self-administered Female Sexual Function Index questionnaire results for all patients, with a follow-up of up to 8 years.

FINDINGS

We noted no long-term postoperative surgical complications. Yearly serial biopsies showed a tri-layered structure, consisting of an epithelial cell-lined lumen surrounded by matrix and muscle, with expected components of vaginal tissue present. Immunohistochemical analysis confirmed the presence of phenotypically normal smooth muscle and epithelia. The MRIs, which showed the extent of the vaginal aplasia before surgery, showed the engineered organs and the absence of abnormalities after surgery, which was confirmed with yearly vaginoscopy. A validated self-administered Female Sexual Function Index questionnaire showed variables in the normal range in all areas tested, such as desire, arousal, lubrication, orgasm, satisfaction, and painless intercourse.

INTERPRETATION

Vaginal organs, engineered from the patient's own cells and implanted, showed normal structural and functional variables with a follow-up of up to 8 years. These technologies could be useful in patients requiring vaginal reconstruction.

Gene expression profile of patients with Mayer-Rokitansky-Küster-Hauser syndrome: new insights into the potential role of developmental pathways

Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is a rare disease characterized by congenital aplasia of uterus and vagina. Although many studies have investigated several candidate genes, up to now none of them seem to be responsible for the aetiology of the syndrome. In our study, we identified differences in gene expression profile of in vitro cultured vaginal tissue of MRHKS patients using whole-genome microarray analysis. A group of eight out of sixteen MRKHS patients that underwent reconstruction of neovagina with an autologous in vitro cultured vaginal tissue were subjected to microarray analysis and compared with five healthy controls. Results obtained by array were confirmed by qRT-PCR and further extended to other eight MRKHS patients. Gene profiling of MRKHS patients delineated 275 differentially expressed genes, of which 133 downregulated and 142 upregulated. We selected six deregulated genes (MUC1, HOXC8, HOXB2, HOXB5, JAG1 and DLL1) on the basis of their fold change, their differential expression in most patients and their relevant role in embryological development. All patients showed upregulation of MUC1, while HOXB2 and HOXB5 were downregulated, as well as Notch ligands JAG1 and DLL1 in the majority of them. Interestingly, HOXC8 was significantly upregulated in 47% of patients, with a differential expression only in MRKHS type I patients. Taken together, our results highlighted the dysregulation of developmental genes, thus suggesting a potential alteration of networks involved in the formation of the female reproductive tract and providing a useful clue for understanding the pathophysiology of MRKHS.

Psychosexual and social consequences in a woman with undiagnosed Mayer-Rokitansky-Küster-Hauser syndrome

PURPOSE

To report a woman with devastating psychosexual and social consequences as a result of undiagnosed Mayer-Rokitansky- Küster-Hauser syndrome (MRKH) syndrome.

MATERIALS AND METHODS

An 18-year-old woman was referred after being divorced for "absent vagina and uterus". On examination, secondary sexual characteristics were normal. Vaginal and rectal examinations revealed absent vagina and uterus. Investigations showed normal hormonal profile, 46 XX karyotype, and normal intravenous pyelography. Pelvic ultrasonography and magnetic resonance imaging (MRI) confirmed the absence of the uterus and presence bilateral ovaries.

RESULTS

A diagnosis of MRKH syndrome was made and she underwent successful modified laparoscopic Vecchietti operation for creation of a new vagina. Vaginal dilators were used after the surgery. Two years of follow up confirmed that vaginal length was about ten cm.

CONCLUSION

The proper diagnosis, counseling, and prompt treatment of MRKH syndrome can prevent tragic consequences.

Laparoscopic removal of persistent muellerian duct structures and orchiopexy

The treatment of persistent muellerian duct syndrome with undescended testis usually followed is orchiopexy without excising or partially excising the muellerian duct structures. Since the vas and vessels are intimately adhered to the fallopian tubes and body of the uterus, excision of muellerian duct structures is associated with devascularisation or injury to the vas. Following several reported incidences of malignancies in this residual muellerlan duct structures, we decided to excise them along with orchiopexy in this patient. In the literature there are evidences stating that malignancy could develop at any age ranging from a young boy to an old man. A careful and meticulous dissection avoiding electrocautery allowed excision of the muellerian duct structures without injury to the vas and vessels of the testes. The testes were brought down to the respective scrotal sac.

Uterus transplantation from a deceased donor

OBJECTIVE

To demonstrate the technique for uterus retrieval and transplantation from a multiorgan donor.

DESIGN

Video presentation of our case report. The video uses animation to demonstrate the technique. Institutional Review Board (IRB) approval was obtained.

SETTING

University hospital.

PATIENT(S)

A 21-year-old woman with complete müllerian agenesis.

INTERVENTION(S)

Uterus allotransplantation has been performed from a deceased donor.

MAIN OUTCOME MEASURE(S)

Acquirement of cyclic menstrual function.

RESULT(S)

This video demonstrates the technique for uterus retrieval, perfusion, and transplantation. The recipient patient has been monitored regularly for vascular flow, immunosuppression, and infection control since the operation.

CONCLUSION(S)

Uterus transplantation requires extensive evaluation of the recipient and donor by an experienced multidisciplinary transplantation team both pre- and postoperatively. It has major risks related to surgery, immunosuppression, and pregnancy. Uterus transplantation might be considered promising only after the birth of a near-term healthy baby.

[The laparoscopic Vecchietti technique for vaginal agenesis]

AIM

To evaluate feasibility and surgical long term, anatomic and functional results of the laparoscopic Vecchietti procedure to treat women with vaginal agenesis.

METHODS

We reported six cases of patients with a Mayer-Rokitansky-Küster-Hauser syndrome. The surgical procedure was the same for all patients. The results have been evaluated on the operative time, the intra and postoperative complications, the antalgic drugs consumption, the transit recovery, the hospital stay, the neovagina length, and the post operative sexual satisfaction.

RESULTS

The mean operative time was 77.5 minutes. The mean paracetamol consumption was: 9.8 g. The mean transit recovery, and hospital stay were: 2 days, 9.8 days, respectively. No intra or postoperative complication occurred. The mean neovagina length evaluated at one year follow-up visit was 7.5 cm. Five patients have regular sexual activity. Three of them reported sexual satisfaction and showed having orgasm (clitoral: 3 cases, clitoral and vaginal: 2 cases). The 2 remaining patients reported dyspareunia. The global satisfaction index was of 71.6%.

CONCLUSION

This surgical technique appeared to be safe, effective and reproducible. It allowed to obtain a neovagina with enough length and have encouraging results on sexual functioning Laparoscopy reduces the psychological and aesthetic consequences of surgery, especially for these young patients already distressed by their malformation.

Less invasive new vaginoplasty using laparoscopy, atelocollagen sponge, and hand-made mould

OBJECTIVE

The purpose of this study was to validate the therapeutic efficacy of the innovative surgical approach using laparoscopy, atelocollagen sponge, and hand-made mould on the achievement of a satisfactory neovagina in patients with vaginal agenesis.

STUDY DESIGN

The current study involved four patients diagnosed as having Mayer-Rokitansky-Küster-Hauser syndrome. After creating a vaginal tunnel, the mould wrapped with atelocollagen sponge was placed within the neovagina. The hand-made mould made of expanded polystyrene was started to insert into the neovagina at 7 days after operation. Since this mould is lighter and easier to adjust compared with the previous commercialized ones, it was less stressful for the patients to master the procedure than previous methods.

RESULTS

Average operation time was 124 minutes with average blood loss being 45 ml. Average hospital stay was 23 days. The mean length of the neovagina one week postoperation was 8 cm with two fingers in width in all patients. No remarkable postoperative complications were noted. At two months after surgery, the neovagina was confirmed to be completely epithelialized in all patients, assessed by Schiller's test.

CONCLUSIONS

This innovative surgical procedure using a mould wrapped with atelocollagen sponge may be a more useful approach for the treatment of vaginal agenesis.

[State-of-the-art of classification, diagnosis and treatment of Müllerian anomalies]

Congenital malformations of the female genital tract represent a relevant clinical entity, especially in reproductive age. Novel technological advances improve diagnostic mechanisms for simple to complex malformations with the subsequent implementation of an integrated management plan. This review has the only purpose to communicate updated information regarding all Müllerian anomalies classification systems known, presenting advances in diagnostic procedures and management currently recommended.

Urethral sex in a woman with previously undiagnosed Mayer-Rokitansky-Küster-Hauser syndrome

PURPOSE

To report a case of urethral sex in a woman with previously undiagnosed Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

MATERIALS AND METHODS

A 32-year-old woman presented with severe pain, dysuria, and mild hematuria after each intercourse. Secondary sexual characteristics were normal. Vaginal and rectal examinations revealed an absent vagina and uterus. Further investigations showed a normal hormonal profile, a 46 XX karyotype, and a normal intravenous pyelography. Pelvic ultrasonography and magnetic resonance imaging (MRI) confirmed the absence of a uterus and the presence of bilateral ovaries.

RESULTS

A diagnosis of MRKH syndrome was made and the patient underwent a modified Vecchietti operation for the creation of a new vagina. The urethral meatus was noticeably dilated. Postoperatively, the vaginal length was six to seven cm. Long-term follow-up revealed that she was able to have normal and satisfactory vaginal intercourse without any problems.

CONCLUSION

Urethral intercourse is documented here for the first time in a case of misdiagnosed MRKH syndrome.

Complete androgen insensitivity syndrome and discordant Müllerian remnants: two cases with novel mutation in the androgen receptor

Complete androgen insensitivity syndrome (CAIS) associated with Müllerian remnant is rare during childhood. The Müllerian system usually regresses because of the presence of the anti-Müllerian hormone (AMH) originating from the Sertoli cells of the gonads. Rarely, residual Müllerian structures may exist. We present two cases from the same family, raised as females. They were 12 and 18 years old, respectively, and they had Tanner V breast development but Tanner I-II pubic hair. The older patient had primary amenorrhea. Both have a 46,XY genotype. Pelvic ultrasonography revealed no uterus and ovaries. The patients underwent bilateral laporoscopic gonadectomy. Both had residual Müllerian structures. Mutation analyses were performed, and both patients were found to be carrying a point mutation in exon 4 of the AR gene consisting of a G nucleotide deletion at position c.1890delG, followed by a frame-shift mutation and a stop codon. This mutation has not been described yet in the literature. Although the association with CAIS and Müllerian remnant is rare, no genetic defect specific to androgen insensitivity with Müllerian remnants has been identified so far.
