Background Acne is a very common skin condition during adolescence and adulthood. Patients with uterovaginal agenesis (Mayer-Rokitansky-Küster-Hauser syndrome, MRKH) treated at the Tübingen University Center for Rare Female Genital Malformations, however, clinically appeared to be less frequently affected by acne. The etiology of MRKH syndrome remains unknown. The only known MRKH-associated mutations are located within the WNT4 gene and lead to an atypical form of MRKH syndrome associated with clinical and biochemical hyperandrogenism. Our study aimed to assess the frequency, severity, and self-evaluation of acne in MRKH patients and to correlate the clinical findings with hormone analyses. Methods As part of a cross-sectional longterm follow-up study after laparoscopic assisted creation of a neovagina a questionnaire was sent to 149 MRKH patients aged 16-44 years comprising 26 items concerning prevalence and self-evaluation of acne, and the effects of acne on quality of life. The questionnaire was derived from one used in a former epidemiological study of acne in 4,000 women. Blood for hormone analyses was collected routinely during the clinical visit. Results Fully completed, evaluable questionnaires were returned by 69/149 (46%) women. Of these respondents, 42 (60.1%) showed hyperandrogenemia without other clinical signs of virilization but only 17 (24.6%) reported acne (8 (11.6%) had physiological acne and 9 (13.0%) clinical acne) and only 10 (14.5%) reported receiving medical treatment for their acne. Effects of acne on quality of life were minor. Only 4 patients (5.8%) with PCOS were identified, among them one with physiological acne, the other three within the acne-free group. Conclusions Although hyperandrogenemia is common, acne is significantly less frequent in women with MRKH than reported in the literature for non-MRKH women, and is seldom treated medically. Patients in this study appeared resistant to acne to some extent, possibly due to the sebaceous glands in the acne regions being less sensitive to androgens compared to the normal population. A WNT4 mutation is unlikely to be the main cause of MRKH syndrome in our hyperandrogenemic patients. [ABSTRACT FROM AUTHOR]

Background Susac's Syndrome (SS) consists of the triad of encephalopathy, branch retinal artery occlusions (BRAO) and hearing loss (HL). Histopathologically, SS is characterised by a microangiopathy, and some observations suggest that an immune-mediated damage of endothelial cells might play a role. These findings also implicate a similarity between SS and other autoimmune diseases, most notably juvenile dermatomyositis (JDM). However, SS and JDM are commonly thought to affect distinct and non-overlapping sets of organs, and it is currently not clear how these specificities arise. Moreover, in the absence of clinical trials, some authors suggest that therapeutic approaches in SS should rely on the model of other autoimmune diseases such as JDM. Case presentation Here, we report a case of SS in a 32-year-old pregnant woman. She initially was admitted to the hospital with subacute severe encephalopathy and multifocal neurologic signs. As cranial magnetic resonance imaging (MRI) revealed multifocal white matter lesions including the corpus callosum, erroneously a diagnosis of multiple sclerosis (MS) was made, and intravenous methylprednisolone (IVMP) therapy was initiated. A few days later, an exanthema appeared on the trunk and extremities, which was diagnosed as livedo racemosa (LR). Several weeks later, the patient was readmitted to the clinic with an obscuration of her left visual hemifield and a bilateral HL. Ophthalmologic examination revealed extensive ischemic damage to both retinae. Now the correct diagnosis of SS was established, based on the above triad of clinical symptoms in conjunction with typical MRI and fundoscopic findings. When SS was diagnosed, the standard therapy with intravenous cyclophosphamide (IVCTX) was not instituted because of a significant risk of permanent infertility. Instead, sustained control of disease activity could be achieved with a therapeutic regime combining prednisolone, intravenous immunoglobulins (IVIG), mycophenylate mofetil (MM), and methotrexate (MTX). Conclusions An association with LR has only been described in very few cases of SS before and further underlines the pathogenetic relationship between SS and other autoimmune diseases such as JDM. In young women with SS and the desire for a child the combination of MM and MTX may represent a reasonable alternative to IVCTX. [ABSTRACT FROM AUTHOR]
