Abstract
BACKGROUND Systemic mastocytosis (SM) is a clonal disorder of mast cells (MCs) frequently associated with vertebral osteoporosis (OP) and subsequent vertebral fractures (VFs). The natural history of this OP remains unclear. Importantly, we do not know whether OP represents an early event triggered alongside MC abnormalities, and whether MC clonality is sufficient to trigger osteoporosis. OBJECTIVE To describe OP in patients with medullar clonality in cutaneous mastocytosis (CM) and monoclonal mast cell activation syndrome (MMAS) and to compare their osteoporosis characteristics with those of nonadvanced SM patients (bone marrow mastocytosis and indolent systemic mastocytosis). METHODS We retrospectively analyzed clinical, biological, and densitometric data of 27 CM, 13 MMAS, and 135 SM patients from the Mastocytosis Expert Center (CEREMAST) in Toulouse, France. RESULTS The OP (respectively 3.7, 30.8, and 34.1%) and VFs (0.0%, 15.4%, and 20%) were less frequent in CM than in MMAS and SM, despite the presence of clonal MCs in the bone marrow. Most patients with OP and VFs in the non-SM groups had the usual risk factors for OP. Interestingly, the only non-SM patient with a typical SM-like OP had high bone marrow tryptase, developed bone marrow KIT mutation during follow-up, and had a family history of SM. Our data show that OP is not a common clinical finding in CM but is frequent in MMAS. When OP and VFs occur in CM and MMAS patients, they differ from the usual phenotype of SM bone fragility. CONCLUSIONS Our findings suggest that, in most CM patients, the meaning and management of OP differs from that of OP in MMAS and nonadvanced SM. Prospective longitudinal studies and the validation of predictors are needed to identify CM and MMAS patients developing SM-related OP.

Abstract
Congenital ichthyoses (CI) comprise a heterogeneous group of monogenic genetic skin diseases characterized by diffuse scaling, often associated with skin inflammation. Diagnosis of the individual form of ichthyosis is complex and is guided by clinical expertise. CI usually has a major impact on quality of life (QOL) and thus requires lifelong treatment. To date, there are no curative therapies, although various symptomatic treatment options exist. The present protocol for the management of CI has been drawn up in accordance with the recommendations published in 2012 by the French National Authority for Health, based on a literature review, with the help and validation of members of the French network for rare skin diseases (FIMARAD). It provides a summary of evidence and expert-based recommendations and is intended to help clinicians with the management of these rare and often complex diseases.

Abstract
BACKGROUND Low-flow malformations (LFMs) are rare diseases with a significant impact on health-related quality of life (HRQoL), especially in children. No disease-specific questionnaire is available for children with LFMs. OBJECTIVE To develop and validate a specific HRQoL questionnaire for children from 11 to 15 years old suffering from LFMs. METHODS A preliminary questionnaire based on a verbatim from focus groups was created and sent to children from 11 to 15 years old suffering from LFMs, together with a dermatology specific and a generic HRQoL questionnaire (cDLQI and EQ-5D-Y). RESULTS A total of 75 from 201 included children responded to the questionnaires. The final version of the questionnaire (cLFM-QoL) included 15 questions and was not divisible into subscales. It demonstrated excellent internal consistency (cronbach 0.89), convergent validity and readability (SMOG 6.04). cLFM-QoL mean score (+ SD) was 12.9/45 (8.03) for all grades of severity, for mild 8.22/45 (7.5), moderate 14.03/45 (8.35), severe 12.35/45 (6.59) or very severe patients 20.7/45 (3.39) (p 0.006). CONCLUSION cLFM-QoL is a validated short and easy to use specific questionnaire with excellent psychometric capacities. It will be suitable for any children 11 to 15 with LFMs, in daily practice or clinical trials.

Abstract
Background Mastocytosis is a rare disease characterised by the accumulation and/or proliferation of abnormal mast cells (MCs) in one or several organs. It may present with a number of different symptoms that involve various organ systems. The current study aims to assess the prevalence of MC mediator-related symptoms in a cohort of mastocytosis patients with a specific focus on neurological, psychiatric, cognitive and sexual symptoms. We also assessed the impact of the disease on patients’ professional lives. Patients were administered a validated multidimensional questionnaire to collect information on patients’ perception of the severity of their symptoms. From the questionnaires we extracted the neurological, cognitive, psychiatric and sexual symptoms and the impact of the disease on patients’ professional lives as well as their grading. The affective status was assessed using the 17-item version of the Hamilton Depression Rating Scale. Results We included 139 patients. Mastocytosis was classified as systemic in 113 patients and cutaneous in 26 patients. The prevalence of MC mediator-related systemic symptoms was as follows: cutaneous (71%), gastro-intestinal (48%), cardio-vascular (36%), musculoskeletal (26.6%), fatigue (24%), urinary (14.4%) and respiratory (10%). Headaches and vertigo were noted in respectively 55% and 32% of patients. Irritability, episodes of memory loss and difficulty concentrating were reported in 54%, 52% and 40% of cases, respectively. Sexual impairment was noted in 24% of patients. No associations were found between neuropsychiatric/cognitive impairment and age, gender, diagnostic delay, disease form, the presence of cutaneous lesions, the level of serum and bone marrow tryptase and the presence of KIT mutation in bone marrow and/or skin. Depression was noted in 49% of patients. One in four patients reported a negative impact of the disease on their professional lives. Conclusion This current study provides some insights regarding symptoms related to mastocytosis and their impact on patients’ professional lives.

Abstract
Proteus Syndrome is a rare complex overgrowth syndrome. We report a young female patient with Proteus Syndrome due to AKT1 mutation c.49G > A (p.Glu17Lys), presenting with a severe gynaecological involvement which necessitated a complete hysterectomy and a left adnexectomy. Cases of gynecological involvements in Proteus Syndrome are rare, not well known by physicians while they can be potentially severe.

Abstract
BACKGROUND Ichthyosis prematurity syndrome is a rare syndromic form of ichthyosis caused by mutations in FATP4, which plays a central role in the transport and activation of fatty acids in the epidermis and in epidermal barrier function. Despite stereotypical clinical presentation in the neonatal period, the diagnosis is not well known by clinicians. Herein we report two new cases. PATIENTS AND METHODS Case no. 1: a boy born prematurely (33weeks of gestation) to non-consanguineous French parents presented at birth with respiratory distress necessitating admission to intensive care. His skin was covered by a thick caseous vernix, especially on the scalp, eyebrows and 4 limbs. At the age of 4years, the boy's skin appeared normal. Case no. 2: a boy born prematurely to consanguineous Moroccan parents (34weeks of gestation) presented at birth with respiratory distress requiring admission to intensive care. At clinical examination, he had a whitish thick skin giving an impression of vernix caseosa, with involvement of the scalp, forehead, 4 limbs and abdomen. At the age of 2 years, his skin was normal. CONCLUSION The clinical presentation of this syndrome is typical. It is important to make the diagnosis to enable genetic counseling and planning of adequate neonatal care in the event of future pregnancies.

Abstract
Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of monogenic genodermatoses that encompasses non-syndromic disorders of keratinization. The pathophysiology of ARCI has been linked to a disturbance in epidermal lipid metabolism that impaired the stratum corneum function, leading to permeability barrier defects. Functional characterization of some genes involved in ARCI contributed to the identification of molecular actors involved in epidermal lipid synthesis, transport or processing. Recently, PNPLA1 has been identified as a gene causing ARCI. While other members of PNPLA family are key elements in lipid metabolism, the function of PNPLA1 remained unclear. We identified 5 novel PNPLA1 mutations in ARCI patients, mainly localized in the putative active enzymatic domain of PNPLA1. To investigate Pnpla1 biological role, we analysed Pnpla1-deficient mice. KO mice died soon after birth from severe epidermal permeability defects. Pnpla1-deficient skin presented an important impairment in the composition and organization of the epidermal lipids. Quantification of epidermal ceramide species highlighted a blockade in the production of ω-O-acylceramides with a concomitant accumulation of their precursors in the KO. The virtually loss of ω-O-acylceramides in the stratum corneum was linked to a defective lipid coverage of the resistant pericellular shell encapsulating corneocytes, the so-called cornified envelope, and most probably disorganized the extracellular lipid matrix. Finally, these defects in ω-O-acylceramides synthesis and cornified envelope formation were also evidenced in the stratum corneum from PNPLA1-mutated patients. Overall, our data support that PNPLA1/Pnpla1 is a key player in the formation of ω-O-acylceramide, a crucial process for the epidermal permeability barrier function.
