Real-time mobile teledermoscopy for skin cancer screening targeting an agricultural population: an experiment on 289 patients in France.

BACKGROUND: The incidence of skin cancer has reached epidemic proportions in the white population and is significantly elevated in agricultural populations, who are exposed to ultraviolet radiation during their professional activities. In 2014, the Agricultural Social Insurance Mutual Benefit Fund (MSA) offered its customers who work in agriculture and live in rural areas with reduced access to dermatologists the ability to participate in a 1-day teledermoscopic (TDS) screening event. OBJECTIVE: This study's aim was to assess the feasibility of real-time mobile TDS triage of a large number of agricultural workers by trained medical officers and occupational physicians. METHODS: Fifteen TDS screening centres were located in different areas of France. Individuals older than 18 years who worked in agriculture and lived in rural area near a TDS screening centre were invited to participate in a 1-day screening event and were examined by an MSA physician. In cases of suspicious skin lesions, clinical and dermoscopic images were obtained and transferred immediately to four dermatologists who were simultaneously present at the tele-platform for diagnosis and decision-making. Low-quality images were retaken. RESULTS: Two-hundred eighty-nine patients underwent skin cancer screening. Among 199 patients (69%), 390 suspicious lesions were identified and generated 412 pictures. All lesions were analysed by dermatologists. For 105 patients (53%), no follow-up was required. Seventeen patients were referred to local dermatologists for rapid examination, including 12 cases of suspected malignant melanocytic lesions. Among the 12 patients with suspected melanoma, face-to-face visits were conducted within 10 days for 11 of them, and 1 case of melanoma was confirmed by histopathology. CONCLUSIONS: Our study suggests that teledermoscopy performed in the context of occupational medicine and targeted to agricultural populations is feasible and could be useful for improving skin cancer screening in at-risk populations while avoiding face-to-face examinations by a dermatologist in 53% of cases.

[Ainhum and "African acral keratoderma": three cases]. / Aïnhum et « kératodermies acrales africaines ¼ : trois cas.

BACKGROUND: Ainhum, or spontaneous dactylitis, involves the formation of a gradual constriction in the digital-plantar fold of the fifth toe that leads, after several years, to autoamputation of the digit. This condition is classically distinguished from "true" ainhum, of unknown aetiology and affecting only subjects of African origin, from "pseudo-ainhum", resulting from different causes such as inflammatory constriction or constriction by a foreign body, and finally from ainhumoid palmoplantar keratoderma, which is of genetic origin and occurs for instance in Vohwinkel syndrome. Herein, we report three cases of ainhum in women of sub-Saharan African origin; in addition, all three subjects were also presenting various forms of hyperkeratosis of the hands and feet known to primarily affect subjects of African origin. PATIENTS AND METHODS: The three patients, aged 30, 48 and 44 years, were respectively from Mali, Guinea and Senegal. They had consulted a dermatologist for violent pain in the fifth toe, which frequently prevented sleep and was inexplicable despite several consultations, and even in one case in spite of surgical investigation. Once the diagnosis had been made, relief was promptly provided for all three patients through Z-plasty to remove the circular constriction around the toe in question. In addition to ainhum, the first patient was also presenting diffuse palmoplantar keratoderma, together with an aspect of acrokeratoelastoidosis on the edges of her hands and feet, and knuckle pads, while the second was presenting diffuse palmoplantar keratoderma and an aspect of marginal acrokeratoelastoidosis, and the third was presenting small knuckle pads. DISCUSSION: A recent study has confirmed the high incidence of several forms of palmoplantar keratoderma of African origin, as well as frequent association of these different varieties with one another. These consist of diffuse keratoderma having a relatively non-specific aspect, keratoderma punctata of the palmar creases, marginal keratoderma known also as focal acral hyperkeratosis, and acrokeratoelastoidosis, despite the absence of histological evidence, and finally, inverted keratoderma, i.e. affecting the dorsal aspects of the extremities, such as knuckle pads. In the three cases presented here, ainhum was associated with these different forms of acral keratoderma seen chiefly in subjects of African origin. CONCLUSION: So-called "true" ainhum may be included in a broader group of African acral keratoderma, further reinforcing the unity of this group. Genetic studies are required to enable validation and refinement of these clinical findings.

Association of glycerol and paraffin in the treatment of ichthyosis in children: an international, multicentric, randomized, controlled, double-blind study.

BACKGROUND: Efficacy and tolerance should be considered in topical treatments of chronicle affections with impaired skin barrier function such as ichthyosis. OBJECTIVES: To demonstrate the efficacy of Dexeryl in reducing severity of ichthyosis. METHODS: A prospective, multicentre, randomized, placebo controlled study was performed with patients under 18 years suffering from a non-bullous form of ichthyosis. A double-blind period using Dexeryl (an emollient cream containing glycerol 15% and paraffin 10%) or placebo (its vehicle) during 4 weeks followed by an open label period with all patients treated by Dexeryl for 8 weeks. Improvement of ichthyosis was assessed by cutaneous xerosis evolution (SRRC score): the percentage of patients with 50% reduction of the SRRC score at D28 was the primary criterion. The assessment of pruritus [visual analogue scale (VAS)], global evaluation and safety were secondary. RESULTS: The percentage of patients with at least 50% reduction of SRRC score at D28 was significantly higher in Dexeryl group (60.3%) vs. vehicle group (43.5%; P = 0.008). Reduction of pruritus on VAS was significantly higher at D28 with Dexeryl (-2.16) compared to that in placebo (-1.49), P < 0.05. The improvement continues through the open label period: at D84 we observed -2.5 of SRRC score in the Dexeryl group vs.-1.8 for the group previously treated by vehicle. Investigators found Dexeryl efficacy as satisfying for about 80% of treated patients vs. 50% with vehicle. Concerning safety, most of the adverse events were not related to treatment. CONCLUSIONS: Dexeryl showed a significant improvement of xerosis and related symptoms in children with ichthyosis and was well tolerated.

Short- and medium-term efficacy of specific hydrotherapy in inherited ichthyosis.

BACKGROUND: Management of inherited ichthyoses is symptomatic. Despite treatment, skin symptoms have a major impact on patients' quality of life (QoL). OBJECTIVES: To assess the short- and medium-term efficacy of hydrotherapy on QoL and clinical symptoms of patients with inherited ichthyosis. METHODS: In this 9-month prospective, open-label, multicentre study, 20 children and 24 adults with ichthyosis were enrolled in several French reference and competence centres, 2 months before undergoing a 3-week treatment with specific hydrotherapeutic management at Avène Hydrotherapy Centre. At baseline (2 months before hydrotherapy), beginning (D0) and end of hydrotherapy (D18), and 3 and 6 months later at the reference and competence centres, patients self-assessed QoL using the Dermatology Life Quality Index (DLQI) or its paediatric version (Children's DLQI), and investigators evaluated ichthyosis severity using a specific clinical ichthyosis score. RESULTS: The DLQI scores were significantly improved not only at the end of the hydrotherapy treatment (-56% vs. baseline; mean ± SD 3·59 ± 4·30 at D18 vs. 8·35 ± 5·71 at D0; P < 0·0001), but also at 3 months (-28% vs. baseline; P = 0·01) and 6 months after hydrotherapy (-26% vs. baseline; mean ± SD 5·21 ± 5·11 vs. 6·89 ± 5·38; P = 0·03) (primary criterion). Clinical symptoms were also significantly improved at all post-treatment visits, with a decrease of the mean clinical ichthyosis score by -38% between D0 and D18, by -30% at 3 months and by -31% at 6 months vs. baseline. CONCLUSIONS: A 3-week treatment at Avène Hydrotherapy Centre provided significant and persisting improvement of QoL and clinical symptoms in patients with inherited ichthyoses.

[Surgical treatment of keratosis palmaris in Mal de Meleda]. / Peut-on traiter chirurgicalement le Mal de Meleda (kératodermie palmoplantaire diffuse de Siemens) ?

BACKGROUND: Mal de Meleda (MDM, OMIM #248300) is a rare congenital palmoplantar keratosis. Deep fissures cause pain and limit extension of the metacarpo-phalangeal joints. We report the case of a patient operated on both hands with a 29-year interval between each hand. OBSERVATIONS: A 53-year-old patient with MDM demonstrated severe keratosis of the left hand. The same surgeon operated on the right hand. Both hands were operated using the same technique. Skin of the palm, the palmar side of the index, and the first phalangeal of third, fourth and fifth fingers were excised with a sharp rugine. The hand was immediately covered by a full thickness-skin graft (FTSG) harvested on groin. CONCLUSIONS: The excision of all keratosis on the palm can lead to complete cure of MDM symptoms. FTSG is essential, especially on the fingers, in order to minimize secondary retraction. At the palm, FTSG offers better mechanical resistance then a split-thickness skin graft. A large groin graft, with closure of the donor site in a Y fashion, can cover the entire hand. Long term follow-up (29 years) demonstrates no recurrence of keratosis on surgically treated areas.

Oral liarozole vs. acitretin in the treatment of ichthyosis: a phase II/III multicentre, double-blind, randomized, active-controlled study.

BACKGROUND: Liarozole, a retinoic acid metabolism blocking agent, has been granted orphan drug status for congenital ichthyosis by the European Commission and the U.S. Food and Drug Administration. OBJECTIVES: The purpose of this trial was to investigate the efficacy, tolerability and safety of oral liarozole vs. acitretin in patients with ichthyosis. METHODS: In this double-blind comparative trial of liarozole vs. acitretin, 32 patients with ichthyosis were randomized to be treated with either oral liarozole 75 mg in the morning and 75 mg in the evening or with acitretin 10 mg in the morning and 25 mg in the evening for 12 weeks. Clinical efficacy, tolerability and safety were monitored. RESULTS: Between-group comparisons for efficacy and tolerability revealed no statistically significant differences except for scaling on the trunk at baseline which was significantly worse in the liarozole group (P = 0.024) and showed a more pronounced improvement in this group than in the acitretin-treated patients (P = 0.047). Based on the overall evaluation of the response to treatment at endpoint, 10 of 15 patients in the liarozole group and 13 of 16 patients in the acitretin group were considered by the investigator to be at least markedly improved. The expected retinoic acid-related adverse events were mostly mild to moderate and tended to occur less frequently in the liarozole group. No serious adverse events related to the drugs occurred. CONCLUSIONS: The present study indicates that liarozole at a daily dose of 150 mg is equally effective as a treatment for ichthyosis as acitretin but shows a trend towards a more favourable tolerability profile. The results of this trial warrant further clinical trials to confirm efficacy and safety of liarozole as an orphan drug in ichthyosis.

Evidence of a marked 25-hydroxyvitamin D deficiency in patients with congenital ichthyosis.

BACKGROUND: Vitamin D is essential for bone mineralization, and its deficiency may be the cause of skeletal fractures and osteomalacia. Geographical or ethnic factors may modulate the cutaneous synthesis of vitamin D. We hypothesized that major changes in keratinization may similarly alter the cutaneous synthesis of vitamin D. OBJECTIVES: To explore calciotrophic hormones, parameters of bone remodelling and bone mineral density (BMD) in nine patients with non-bullous congenital ichthyosis. PATIENTS AND METHODS: Six patients were European, three were North African. Four had received acitretin over a long period of time. A complete biological investigation, including serum and urinary calcium and phosphorus, calciotrophic hormones [intact parathyroid hormone (iPTH), 25-hydroxyvitamin D (25-(OH)D) and 1,25-dihydroxyvitamin D (1,25-(OH)2D)], bone formation and resorption markers, was performed on all patients during the winter season and repeated among four patients after summer. BMD was measured in all patients. RESULTS: All patients had a marked 25-(OH)D deficiency, clearly below the deficiency threshold of 25 nmol/L. Patients from North Africa had a greater deficiency than European patients, perhaps because of the difference in skin pigmentation. iPTH remained normal in European patients but was elevated among the North Africans. After sun exposure, an improvement in vitamin status was visible in only one patient. Bone formation and resorption markers remained normal. Femoral neck osteodensitometry indicated values near the osteopaenic threshold in two young North African females. No deleterious effect of retinoids on vitamin D metabolism was observed. CONCLUSION: Patients, and in particular pigmented patients, with congenital ichthyosis present a severe deficiency in vitamin D. Care provided to protect the skeletal future of these patients involves measuring BMD and prescribing supplementation.

Using Urgotul dressing for the management of epidermolysis bullosa skin lesions.

OBJECTIVE: To evaluate the acceptability, tolerance and efficacy of Urgotul wound dressing in the management of epidermolysis bullosa (EB) skin lesions. METHOD: This was an open-label uncontrolled clinical trial involving 20 patients (I I adults and nine children) with EB simplex or dystrophic EB. Patients were selected from the register of EB patients at the investigating centre and included if they presented with at least one skin lesion requiring management with a non-adherent wound dressing. Lesions were treated with the study dressing for a maximum of four weeks. All dressing changes, wound parameters, pain and effect on quality of life were recorded. RESULTS: All patients completed the trial. Nineteen out of 20 wounds healed within 8.7 +/- 8.5 days. Overall, 11 patients (55%) considered that their quality of life had improved following use of the dressing, which was also reported to be pain free and 'very easy' or 'easy' to remove at most dressing changes. Nineteen out of 20 patients stated that they would use the study dressing to manage their lesions in future. CONCLUSION: This study confirmed the very good acceptability and efficacy of Urgotul in the treatment of skin lesions in patients with EB.

[Role of cutaneous pinch grafts in the healing of patients with dystrophic epidermolysis bullosa wounds: report of four cases]. / Intérêt des greffes de peau en pastilles dans les épidermolyses bulleuses dystrophiques. A propos de quatre cas.

Epidermolysis bullosa (EB) is a heterogeneous group of genetically determined skin fragility disorders in which minor trauma leads to blister formation on the skin. One of the most severe forms is Hallopeau-Siemens recessive dystrophic EB which main cause of mortality is squamous cell carcinoma (SCC). Exeresis of SCC leads to a difficult problem about treating the surgical wound. Most of the time, achieving a split-thickness skin graft on these severely affected EB patients is either too difficult or gives poor quality results. In some cases, flaps could be performed but they represent a too aggressive solution. However cutaneous pinch grafting is really adapted to the healing of these wounds. We have reported 4 cases of patients with recessive dystrophic EB complicated with SCC from 30 mm to 270 mm. After surgical excision of these SCC, dressings have been applied until obtaining a good enough floor for achieving a skin graft. The four patients have been treated by cutaneous pinch grafting. Airway management and monitoring have required particular precautions for avoiding anaesthetic related morbidity. We have noticed no adverse effect. A complete healing of good quality has been obtained in all cases (3 to 16 months of follow-up). No recurrence of SCC has been noticed and donors sites have had got a good healing. Relating to the healing of wounds after exeresis of SCC in case of dystrophic EB, cutaneous pinch grafting represents the most reliable solution with a minimum of physical traumatism.

[Recessive dystrophic epidermolysis bullosa (Hallopeau-Siemens) with IgA nephropathy: 4 cases]. / Epidermolyse bulleuse dystrophique récessive d'Hallopeau-Siemens associée à une glomérulonéphrite à dépôts mésangiaux d'IgA: 4 cas.

BACKGROUND: The Hallopeau-Siemens type of recessive dystrophic epidermolysis bullosa (HS-RDEB) is a severe hereditary dermatosis, associated with a collagen VII deficiency. A chronic inflammatory syndrome, secondary to recurrent cutaneous infections, may be the cause of AA amyloidosis, with chronic renal failure, involving life prognosis. Less frequently, an IgA glomerulonephritis may occur and induce renal failure. Only two cases have been previously described. We report herein four new cases. CASE REPORT: We report four cases of HS-RDEB associated with IgA glomerulonephritis. A renal biopsy confirmed the diagnosis in all four cases. Later on, two patients had a second renal biopsy, indicated for deterioration of renal function. One of these patients showed AA type renal amyloidosis on the second biopsy. None of these six biopsies, conducted in our four patients led to local cutaneous complications. Subsequently three patients presented with terminal renal failure. Hemodialysis was set up, with good tolerance and improvement in quality of life. DISCUSSION: IgA glomerulonephritis should be suspected if a patient with HS-RDEB presents with hematuria. Renal biopsy is not contraindicated, confirms the diagnosis and helps to specify the prognosis. Hemodialysis is possible and well tolerated in the terminal stage of renal failure. There is not enough evidence for a genetic link between HS-RDEB and IgA glomerulonephritis, but repeated skin infections may be involved in the pathophysiology of the renal disease.

Vitamin and trace metal levels in recessive dystrophic epidermolysis bullosa.

BACKGROUND: In recessive dystrophic epidermolysis bullosa (RDEB), a good nutritional balance is necessary to obtain healing of the chronic wounds. However, involvement of the oral mucosa and oesophagus stenosis may be responsible for severe nutritional deficiencies. OBJECTIVE: In order to propose an adapted nutritional management, we studied the vitamin and trace metal status of 14 RDEB patients. METHODS: Height and weight were measured. Plasma levels of albumin, iron, ferritin, calcium, parathyroid hormone (PTH), folates, vitamins C, D, B12, A, E, B1, B6, PP and B2, zinc, selenium, carnitine and copper were measured. RESULTS: Most patients had a significant growth retardation. We found iron, vitamin D, C, B6, PP, zinc and selenium deficiencies in 36-70% of the patients, without clinical expression, except in one case. Vitamin B1, 12, B2, A/RBP, E/lipids and carnitine were normal. The three patients with gastrostomy feeding had better growth but still a protein deficiency and sometimes vitamin C, B6, PP, zinc and carnitine deficiencies. CONCLUSION: Vitamin and trace metal deficiencies are frequent in RDEB, even in patients receiving gastrostomy feeding, and often go unrecognized. Regular nutritional evaluation is necessary. Dietary advice and supplements should be given. Enteral feeding by gastrostomy should be discussed in early childhood.

Bullous and non-bullous ichthyosiform erythroderma associated with generalized pustular psoriasis of von Zumbusch type.

Bullous ichthyosiform erythroderma (BIE) and non-bullous ichthyosiform erythroderma (NBIE) are rare congenital ichthyoses. Generalized pustular psoriasis (GPP) of von Zumbusch type is a rare and severe form of psoriasis marked by desquamative and pustular erythroderma associated with fever and altered general conditions. We report two adults with an ichthyosis typical of BIE in the first case and NBIE in the second, without any previous history of psoriasis, who presented with a severe and relapsing GPP of von Zumbusch type. Using current knowledge of the genetic relationship between psoriasis and congenital ichthyoses, we discuss the possibility of a common physiopathological link between congenital ichthyoses and GPP, and examine the possible therapeutic problems resulting from this pathological association, especially in BIE.

Comparison of the capsular response to the Biocell RTV and Mentor 1600 Siltex breast implant surface texturing: a scanning electron microscopic study.

The utility of mammary prosthesis texturing in the prevention of capsular contracture was established some 20 years ago. Various models of implant texturing are currently on the market. We decided to study two of the most popular implants with two different surface texturings: the Biocell RTV and the Mentor 1600 Siltex. An observation at the electron microscopic level of the implants' surfaces was achieved. At the time of a prospective survey on 10 patients, the capsule fragments corresponding to these two prostheses have been analyzed at the electron microscopic level. All prostheses were removed from the patients because of asymmetry or bad positioning. The aim of our study was to establish a correlation between these two frequent texturing surfaces and their corresponding capsules. Our results showed that only the Biocell's capsules present a mirror image with correspondence of the depressions on the prosthesis and contacts on the capsule. This phenomenon seems linked to the existence of a critical size of the pores constituting the implant surface. This observation leads us to the hypothesis of an adhesive effect between the prosthesis and its capsule. If this last is not directly linked to the prevention of capsular contracture, it can have an effect on implant stabilization in the primary mammary reconstruction and in the secondary corrections of asymmetry or bad position.

[A scanning electron microscopy study of the surface of porous-textured breast implants and their capsules. Description of the "velcro" effect of porous-textured breast prostheses]. / Etude au microscope électronique à balayage des surfaces des implants mammaires à texturation poreuse et de leurs capsules. Description de l'effet "velcro" des prothèses à texturation poreuse.

The efficacy of breast prosthesis texturing in the prevention of capsular contracture has been established for about 20 years. This successful procedure has led to the development and marketing of a number of different models. In the present study, four porous-textured breast prostheses have been examined: the Arion monoblock implant, the CUI (McGahn), the Biocell (Mcgahn), and the Sebbin LS21. Scanning electron microscopic (SEM) investigation of the implant surfaces of the different prostheses was carried out on new samples received from the manufacturers. During a prospective study on eight patients, capsule samples corresponding to the four above-mentioned prostheses were taken to determine whether a secondary intervention was necessary for correction of asymmetry or malpositioning. These samples were analyzed by SEM to investigate whether there could be a correlation between prosthesis texturing and the aspect of the corresponding capsules. Significant ultrastructural differences were found between the various prostheses examined: the results showed that only the CUI and Biocell prostheses presented a mirror image of the capsule texturing, with a correspondence between the depressions on the prosthesis and the contacts on the capsule. This finding seems to be linked to the existence of a critical size for the pores that constitute the implant surface. This observation led to the hypothesis of an adhesive "velcro" effect between the prosthesis and its capsule. Although the latter may not be directly linked to the prevention of capsular contracture it can, however, have a major effect on implant stabilization in cases of primary breast reconstruction and in possible secondary adjustments of asymmetry and malpositioning.

[Schopf-Schulz-Passarge syndrome: 2 cases]. / Syndrome de Schopf-Schulz-Passarge: 2 observations.

BACKGROUND: Schöpf-Schulz-Passarge's syndrome is a rare autosomal recessive genodermatosis associating hypodontia, palmoplantar keratoderma, cysts of the eyelid margins, onychodysplasia and hypotrichosis. We report two new cases. CASE REPORT: Case no. 1: A 49 year-old woman complained of erosive and fissured palmoplantar keratoderma. Nails were fragile and dystrophic. Permanent teeth were absent. She also had many small cysts of the eyelid margins and a middle hypotrichosis. There was no consanguinity between her parents. Case no. 2: A 56 year-old man was seen for red, scaly and well marked palmoplantar keratoderma. Permanent teeth were absent. He had a hair loss since the age of 30. Nails were hypoplastic and there were many small cysts of the eyelids. Biopsy of one of the cysts showed a follicular cyst associated with sweat duct dystrophy. Schöpf-Schulz-Passarge's syndrome was diagnosed in these 2 patients. There was no evidence of associated cutaneous tumors. DISCUSSION: Differential diagnosis of Schöpf-Schulz-Passarge syndrome include other genodermatoses comprising palmoplantar keratoderma and dental abnormalities. Benign or malignant tumors are frequently associated: eccrine poromas, eccrine syringofibroadenomas, follicular tumors, basal cell and squamous cell carcinomas. Tumors usually appear after the age of 60. Regular follow-up and biopsy of the suspect lesions are necessary.

Novel point mutations, deletions, and polymorphisms in the cathepsin C gene in nine families from Europe and North Africa with Papillon-Lefèvre syndrome.

Papillon-Lefèvre syndrome is an autosomal recessive disorder characterized by palmoplantar keratoderma, periodontitis, and premature loss of dentition. Mutations in the CTSC gene that encodes cathepsin C have been described in families affected with Papillon--Lefèvre syndrome. Cathepsin C is the least understood of the lysosomal cysteine proteases; it has been reported to participate in both intracellular and extracellular cleavage of proteins and activation of serine proteases in immune and inflammatory cells. We report here eight new mutations in Papillon-Lefèvre syndrome families: four deletions and four point mutations, including a missense mutation in the propeptide chain that could help elucidate structure-function relationships in this protein. We also found that the 458C > T mutation, first reported in two families by Hart et al (2000c), was a neutral polymorphism in our families, as suggested by Allende et al (Cathepsin C gene: first compound heterozygous patient with Papillon--Lefèvre syndrome and novel symptomless mutation. Hum Mutat 17:152-153, 2001).

Refined localization of the gene for Clouston syndrome (hidrotic ectodermal dysplasia) in a large French family.

Hidrotic ectodermal dysplasia (HED) or Clouston syndrome is a rare autosomal dominant disorder characterized by nail dystrophy, alopecia and palmoplantar hyperkeratosis, which maps to chromosome 13q11-q12.1. We confirmed linkage of HED to this region in a large French family. To define the critical region for HED, detailed haplotypes were constructed with new pericentromeric polymorphic markers. A recombination event in the family indicates that the HED locus maps centromeric to D13S1832. Our French family does not share a common haplotype with other pedigrees previously published (particularly French-Canadian), indicating that the mutations in these families are likely to be of different origin.

Prenatal diagnosis of pyloric atresia-junctional epidermolysis bullosa syndrome in a fetus not known to be at risk.

Junctional epidermolysis bullosa with pyloric atresia (PA-JEB) is a highly lethal, inherited, autosomal recessive disease. Thus far, prenatal diagnosis of this syndrome was only realized on pregnancies at risk for recurrence. We report the case of a 26-year-old woman, first cousin to her husband, who had undergone amniocentesis for polyhydramnios. The karyotype was normal but the amniotic fluid contained acetylcholinesterase. A targeted scan at 25 weeks' gestation did not find spina bifida, but polyhydramnios with a dilated stomach, and several other anomalies: echogenic particles in the amniotic fluid, a thin skin which closely adhered to the nasal bones, narrow nostrils, abnormal ears, fisted hands, malposition of both first toes, and kidney malformation. Despite no previous case in the family, it was thought that sonographic findings were suggestive of the PA-JEB syndrome. A fetal skin biopsy was carried out at 28 weeks' gestation. The ultrastructural examination of fetal skin displayed JEB. Genetic analysis detected a homozygous mutation in the gene encoding integrin alpha 6. Termination of pregnancy was carried out at 29 weeks' gestation. These results illustrate that in the case of a fetus not known to be at risk, diagnosis of PA-JEB can be achieved by ultrasound findings leading to fetal skin biopsy and ultrastructural examination of blistered epidermis. Some new sonographic signs should raise the possibility of significant cutaneous desquamation and blister formation in a fetus, especially when there is positive amniotic acetylcholinesterase coupled with elevated alpha-fetoprotein or suspected pyloric atresia.
