Abstract
INTRODUCTION Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder that has been reported in all ethnicities, with several identifiable pathogenic variants. There have been reported cases indicating that RTS may lead to low birth weight in fetuses, but specific data on the fetal period are lacking. Genetic testing for RTS II is currently carried out by identifying pathogenic variants in RECQL4. METHODS In order to determine the cause, we performed whole-genome sequencing (WGS) analysis on the patient and his parents. Variants detected by WGS were confirmed by Sanger sequencing and examined in family members. RESULTS After analyzing the WGS data, we found a heterozygous nonsense mutation c.2752G>T (p.Glu918Ter) and a novel frameshift insertion mutation c.1547dupC (p.Leu517AlafsTer23) of RECQL4, which is a known pathogenic/disease-causing variant of RTS. Further validation indicated these were compound heterozygous mutations from parents. CONCLUSION Our study expands the mutational spectrum of the RECQL4 gene and enriches the phenotype spectrum of Chinese RTS patients. Our information can assist the patient's parents in making informed decisions regarding their future pregnancies. This case offers a new perspective for clinicians to consider whether to perform prenatal diagnosis.

Abstract
Rothmund-Thomson Syndrome (RTS) is a rare autosomal recessive disease which manifests several clinical features of accelerated aging. These findings include atrophic skin and pigment changes, alopecia, osteopenia, cataracts, and an increased incidence of cancer for patients carrying RECQL4 germline mutations. Mutations in RECQL4 are responsible for the majority of cases of RTS. RECQL4 belongs to RECQ DNA helicase family which has been shown to participate in many aspects of DNA metabolism. In the past several years, accumulated evidence indicates that RECQL4 is important not only in cancer development but also in the aging process. In this review, based on recent research data, we summarize the common aging findings in RTS patients and propose possible mechanisms to explain the aging features in these patients.

Abstract
Almost 5-10% of all tumours are hereditary, which manifest in tumour syndrome or neoplasmic complication of a genetic disease. We present a short introduction of some of these rare diseases through our patients with the aspect of the clinical signs, diversities and challenges. These cases indicate that the incidency of malignancies are increased at genetic diseases, it means even multiple neoplasms in the same patient. The therapy does not differ from the ordinary tumour's therapy and the results are nearly the same as in cases without genetic diseases.

Mutations in FAM111B cause hereditary fibrosing poikiloderma with tendon contracture, myopathy, and pulmonary fibrosis. Am J Hum Genet 2013; 93:1100-7.

Abstract
Congenital poikiloderma is characterized by a combination of mottled pigmentation, telangiectasia, and epidermal atrophy in the first few months of life. We have previously described a South African European-descent family affected by a rare autosomal-dominant form of hereditary fibrosing poikiloderma accompanied by tendon contracture, myopathy, and pulmonary fibrosis. Here, we report the identification of causative mutations in FAM111B by whole-exome sequencing. In total, three FAM111B missense mutations were identified in five kindreds of different ethnic backgrounds. The mutation segregated with the disease in one large pedigree, and mutations were de novo in two other pedigrees. All three mutations were absent from public databases and were not observed on Sanger sequencing of 388 ethnically matched control subjects. The three single-nucleotide mutations code for amino acid changes that are clustered within a putative trypsin-like cysteine/serine peptidase domain of FAM111B. These findings provide evidence of the involvement of FAM111B in congenital poikiloderma and multisystem fibrosis.

Abstract
Hereditary sclerosing poikiloderma (HSP) is a very rare disease. The clinical features are principally widespread poikiloderma and linear hyperkeratotic and sclerotic bands. We report an 18-yr-old male who presented reticular hyperpigmented lesions on the trunk and extremities since 2-yr-old. Also, linear sclerosing bands appeared on both antecubital and popliteal fossae after yr. Histopathologic finding showed dense sclerotic collagen fibers with telangiectasia in the upper dermis and fragmentations of damaged elastic fibers in the elastic stain, consistent with HSP. We report the first Korean case of HSP.

Abstract
Rothmund-Thomson syndrome (RTS) is a genodermatosis presenting with a characteristic facial rash (poikiloderma) associated with short stature, sparse scalp hair, sparse or absent eyelashes and/or eyebrows, juvenile cataracts, skeletal abnormalities, radial ray defects, premature aging and a predisposition to cancer. The prevalence is unknown but around 300 cases have been reported in the literature so far. The diagnostic hallmark is facial erythema, which spreads to the extremities but spares the trunk, and which manifests itself within the first year and then develops into poikiloderma. Two clinical subforms of RTS have been defined: RTSI characterised by poikiloderma, ectodermal dysplasia and juvenile cataracts, and RTSII characterised by poikiloderma, congenital bone defects and an increased risk of osteosarcoma in childhood and skin cancer later in life. The skeletal abnormalities may be overt (frontal bossing, saddle nose and congenital radial ray defects), and/or subtle (visible only by radiographic analysis). Gastrointestinal, respiratory and haematological signs have been reported in a few patients. RTS is transmitted in an autosomal recessive manner and is genetically heterogeneous: RTSII is caused by homozygous or compound heterozygous mutations in the RECQL4 helicase gene (detected in 60-65% of RTS patients), whereas the aetiology in RTSI remains unknown. Diagnosis is based on clinical findings (primarily on the age of onset, spreading and appearance of the poikiloderma) and molecular analysis for RECQL4 mutations. Missense mutations are rare, while frameshift, nonsense mutations and splice-site mutations prevail. A fully informative test requires transcript analysis not to overlook intronic deletions causing missplicing. The diagnosis of RTS should be considered in all patients with osteosarcoma, particularly if associated with skin changes. The differential diagnosis should include other causes of childhood poikiloderma (including dyskeratosis congenita, Kindler syndrome and Poikiloderma with Neutropaenia), other rare genodermatoses with prominent telangiectasias (including Bloom syndrome, Werner syndrome and Ataxia-telangiectasia) and the allelic disorders, RAPADILINO syndrome and Baller-Gerold syndrome, which also share some clinical features. A few mutations recur in all three RECQL4 diseases. Genetic counselling should be provided for RTS patients and their families, together with a recommendation for cancer surveillance for all patients with RTSII. Patients should be managed by a multidisciplinary team and offered long term follow-up. Treatment includes the use of pulsed dye laser photocoagulation to improve the telangiectatic component of the rash, surgical removal of the cataracts and standard treatment for individuals who develop cancer. Although some clinical signs suggest precocious aging, life expectancy is not impaired in RTS patients if they do not develop cancer. Outcomes in patients with osteosarcoma are similar in RTS and non-RTS patients, with a five-year survival rate of 60-70%. The sensitivity of RTS cells to genotoxic agents exploiting cells with a known RECQL4 status is being elucidated and is aimed at optimizing the chemotherapeutic regimen for osteosarcoma.

Abstract
PURPOSE OF REVIEW The delineation of syndromes carrying a predisposition to malignancy has led to great insights into the molecular biology of malignancy. Many such syndromes have cutaneous findings which can precede the development of neoplasia. Early recognition of the cutaneous stigmata of the genodermatoses with malignant potential can lead to early diagnosis and initiation of proper screening and treatment when indicated. RECENT FINDINGS This article reviews 'classic' genodermatoses with malignant potential and highlights recent recommendations for screening and treatment. Additionally more recently delineated syndromes and their cutaneous findings are discussed. SUMMARY Certain inherited syndromes with a risk of neoplasia exhibit characteristic cutaneous findings. Recognition of these findings by the astute practitioner can lead to early intervention which can impact the course of these rare diseases.

Abstract
The ATP-dependent DNA helicase Q4 (RECQL4) belongs to a family of conserved RECQ helicases that are felt to be important in maintaining chromosomal integrity (Kitao et al., 1998, Genomics: 54 (3): 443-452). Deletions in the RECQL4 gene located on chromosome 8 region q24.3 have been associated with Rothmund-Thomson syndrome (RTS, OMIM 268400), a condition characterized by poikiloderma, sparse hair, small stature, skeletal abnormalities, cataracts and an increased risk of malignancy. We present a patient with a molecularly confirmed diagnosis of RTS with two unique genetic alterations in RECQL4 (IVS16-2A>T and IVS2+27_51del25), who at the age of 7 months nearly succumbed to Pneumocystis carinii pneumonia. Evaluation of his immune system demonstrated a T- B+ NK- phenotype with agammaglobulinemia consistent with combined immunodeficiency (CID). Studies to evaluate for known genetic causes of CID were not revealing. The patient received an umbilical cord blood (UCB) transplant with complete immune reconstitution. This report represents the first description of a CID phenotype and UCB transplantation in a patient with RTS.

Abstract
Kindler syndrome is a rare hereditary disorder characterized by acral blister formation in infancy and childhood, progressive poikiloderma, cutaneous atrophy and increased photosensitivity. Since it was first described in 1954, less than 100 cases have been reported worldwide. Recently it has been reported that Kindler syndrome is the first genodermatosis caused by a defect in the actin-extracellular matrix linkage, and the gene was mapped to chromosome 20p12.3. The clinical features of the syndrome have been annotated by different authors but the definite of criteria to confirm the diagnosis have not yet been generally accepted. We report a case of Kindler syndrome that presents a full spectrum of clinical manifestations, and we propose a set of clinical criteria for diagnosis.

Abstract
Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder that is characterized by skin manifestations, juvenile cataracts, and extracutaneous manifestations. The presence of congenital airway abnormalities has not previously been documented in Rothmund-Thomson syndrome. We report the case of a child with Rothmund-Thomson syndrome suffering from multiple airway abnormalities. Our case highlights the importance of suspecting multiple airway abnormalities in any child with respiratory distress with other systemic anomalies. This necessitates meticulous anatomical and dynamic examination of the laryngotracheo-broncheal tree.

Abstract
Kindler syndrome is a rare genodermatosis characterized by acral bullae and photosensitivity. The photosensitivity improves with advancing age and results in progressive poikiloderma and cutaneous atrophy, and many additional features have also been described. This report describes two male Kindler syndrome patients with classical features of acral blistering and photosensitivity in childhood, and subsequent development of poikiloderma, leukokeratosis of oro-ano-genital mucosae, phimosis and meatal stenosis. The first patient had additional ophthalmic features of chronic simple conjunctivitis caused by persistent irritation, multiple stromal nebular corneal opacities and thickened corneal nerves. The second patient showed skeletal changes, namely a dome-shaped skull (turri-cephaly), bifid fourth rib, missing fifth rib, short fourth and fifth metacarpals and mandibular abnormalities. This is the first report of such ophthalmic and skeletal features of Kindler syndrome.

Abstract
We report on an 18 years old female patient who presented with synechia of the labia. History reveals congenital blistering with acral localization and photosensitivity in childhood. At present, the patient showed wide-spread poikoloderma with reticulate hyperpigmentation, xerosis, proximal synechia between fingers and toes and absence of dermatoglyphics, suggestive for congenital bullous poikiloderma (Kindler syndrome). The diagnosis was confirmed by histology and electron microscopy. Kindler syndrome is a rare, autosomal recessive disorder with synechia of mucosal areas being the presenting symptom.

Abstract
BACKGROUND We report a case of Rothmund-Thomson syndrome associated with a trisomy 8 mosaicism, and RECQ4 gene mutation. OBSERVATION An 18-year-old man presented with a poikiloderma affecting photoexposed areas and the buttocks. This lesions appeared during the first year of life and was secondly associated with alopecia, sparse body hair, keratosis, and warts. He also had proportional short stature, thumb and patella aplasia, particular facies, and plantar malformations. Cytogenetic studies evidenced chromosomal instability and trisomy 8 mosaicism. The DNA repair capacity was normal. A mutation in RECQ4 helicase gene was found. DISCUSSION Rothmund-Thomson syndrome is a rare hereditary syndrome characterized by early onset of poikiloderma. Patients exhibit variable features including skeletal abnormalities, juvenile cataracts, photosensitivity, and a higher than expected incidence of cutaneous or extracutaneous malignancies. Genetic patterns found in Rothmund-Thomson syndrome are heterogeneous. Normal karyotypes have been demonstrated in many patients. Various karyotypic abnormalities or reduced DNA repair was seen in others. Recently, five patients with Rothmund-Thomson syndrome were shown to segregate for mutations in RECQ4 helicase gene. Thus, clinical and genetic features in Rothmund-Thomson syndrome are polymorphous. Therefore, it could be interesting to correlate genotype and phenotype.

Abstract
A syndrome is described in three isolated patients in whom the main features are bilateral radial aplasia, short stature, an inflammatory based 'elastic' pyloric stenosis, a pan-enteric inflammatory gut disorder that appears to be due to an autoimmune process, and poikiloderma. Other features in individual cases include cleft palate, micrognathia, anal atresia, patellar aplasia/hypoplasia and sensorineural deafness. This combination may represent a severe form of Rothmund-Thomson syndrome or possibly a previously unrecognized condition.

Abstract
A 25-year-old Japanese woman presented with contracture of the fingers and toes, and difficulty in opening her mouth. Her grandparents are first cousins, but none of the other members of the family are affected. Bulla formation started at birth on areas of the skin that received pressure, and in infancy and early childhood the lesions were limited only to the acral areas. She also had bilateral, incomplete syndactylies involving all web spaces (Fig. 1a). The formation of blisters ceased after the age of 15 years, but a generalized progressive poikiloderma then appeared with accompanying cutaneous atrophy of the skin of the neck, trunk, and extremities (Fig. 1b). The patient experienced mild photosensitivity of the face and neck. At age 18 years, surgical removal of the webbing of all her fingers was performed. Oral examination showed atrophy of the buccal mucosa, and an inability to fully open the mouth. The patient also suffered from poor dentition and easily bleeding gums, but had no symptoms of esophageal dysfunction. Histology of separate biopsy specimens, taken from the poikilodermatous pretibial and trunk skin, showed classical features of poikiloderma, namely epidermal atrophy with flattening of the rete ridges, vacuolization of basal keratinocytes, pigmentary incontinence, and mild dermal perivascularization (Fig. 2a). Interestingly, dyskeratotic cells (Fig. 2b) and eosinophilic rounded bodies (colloid bodies) (Fig. 2c) were frequently found at the basal keratinocyte layer and in the upper dermis, respectively. Pigment was also present in the upper epidermis. To rule out the possibility of a congenital epidermolysis bullosa, ultrastructural and immunofluorescence studies were performed. Ultrastructural studies demonstrated the reduplication of the basal lamina with branching structures within the upper dermis and cleavage between the lamina densa and the cell membrane of the keratinocytes (Fig. 3a). The numbers of associated anchoring fibrils did not seem to be reduced, and colloid bodies and dyskeratotic cells were detected. Immunofluorescence studies with the antibody against type VII collagen (LH 7 : 2) were subsequently carried out. The results showed extensive broad bands with intermittently discontinuous and reticular staining at the dermo-epidermal junction (DEJ) (Fig. 3b), whereas a linear distribution is typically seen in healthy tissue (data not shown). Interestingly, direct immunofluorescence studies revealed intracellular accumulation of immunoglobulin G (IgG), IgM, IgA, and C3 in colloid bodies under the basement membrane (Fig. 3c).

Abstract
A 64-year-old woman experienced progressive generalized poikiloderma after an episode of sunburn 4 years earlier. The diagnosis of subacute cutaneous lupus erythematosus (SCLE) was confirmed by the presence of anti-Ro/SS-A and antinuclear antibodies, the histology, and the direct immunofluorescent findings (ie, positive lupus band test and "dust-like" epidermal IgG staining pattern). Poikiloderma has not been previously reported in the spectrum of SCLE. As a major pathomechanism of SCLE, photosensitivity might explain this uncommon clinical manifestation of the disease.

Abstract
Primary cutaneous amyloidosis is the deposition of amyloid in the skin without involvement of internal organs. It is easily diagnosed when presented in its typical manifestation. Atypical or rare clinical presentations can pose diagnostic difficulties. Poikiloderma-like cutaneous amyloidosis (PCA), a rare variant of primary cutaneous amyloidosis, was first reported in the literature in 1936 (1). It is characterised by: 1) poikilodermatous skin lesions; 2) lichenoid papules; 3) cutaneous amyloid deposit in the pigmented and lichenoid lesions; 4) light sensitivity; 5) short stature; and 6) other features such as blister formation or palmoplantar keratosis. Ogino coined the term PCA syndrome when these unusual features present early in life (2). We report a 26-year-old Chinese woman who presented with poikilodermatous skin lesions and was misdiagnosed as poikiloderma atrophica vasculare (PAV) on the basis of clinical appearance without any histological proof. The diagnosis of PCA was made after skin biopsy which showed amyloid deposits in the skin. This condition can easily be confused with other true poikiloderma skin diseases. Histology is important in confirming the diagnosis.

Abstract
A male patient with congenital poikiloderma (type Dowling) developed Bowen's disease and initial squamous cell carcinoma. As the patient suffered from hypertriglyceridaemia (Frederickson type IV) and a long term tumor prophylaxis with retinoids was not appropriate, we attempted to treat the hyperkeratotic plaques with dermabrasion. After a period of six month we found complete healing of several plaques and only slight keratoses left in a few others. Long term follow up results are not yet available. Through this case report, the heterogenous clinical picture of congenital poikiloderma with warty hyperkeratoses and its high risk of malignancies is discussed.

Mandibuloacral dysplasia is a rare syndrome characterized by mandibular hypoplasia, delayed cranial suture closure, dysplastic clavicles, abbreviated, club-shaped terminal phalanges, acroosteolysis, atrophy of the skin over the hands and feet, and poikilodermatous skin changes. We describe the cases of two siblings with features of mandibuloacral dysplasia who as children were considered to have hereditary sclerosing poikiloderma. On their reevaluation as adults, the clinical features of their condition were perceived to be compatible with mandibuloacral dysplasia.

Abstract
This report deals with a 15-year-old girl suffering from the verrucous type of Thomson's syndrome. Initial poikilodermatous skin changes developed on both cheeks at the age of 3 months. Subsequently, rapid generalization of typical skin findings was observed. The clinical heterogenity of this syndrome is discussed with reference to the existing literature and the present case. Up to now, very few comparable cases of associated neurological symptoms have been described.

Abstract
Dyskeratosis congenita (DC) is a very rare form of genodermatosis with variable manifestations, which mainly affects male patients. The main clinical symptoms are poikilodermia, nail dystrophy and leucoplakia; there are many other cutaneous and systemic symptoms. To avoid complications and improve the prognosis early diagnosis and regular close surveillance of the patients are important. We report on 13-year-old monozygotic twin brothers who, in addition to the typical symptoms, had increased vulnerability of the skin, scarring of the hands and atrophy of the oral mucosa as well as splenomegaly, pancytopenia with severe aplasia of bone marrow and aseptic necrosis of the hip. The two brothers had nearly synchronous clinical manifestation and progression. This paper reviews the clinical symptoms, pathogenesis, differential diagnosis and genetic aspects of DC.

Abstract
The Rothmund-Thomson syndrome is a rare autosomal recessive condition. It is primarily a clinical diagnosis with manifestations that include poikiloderma, short stature, sparse hair, juvenile cataracts, small hands and feet, bone defects, photosensitivity, hypogonadism, defective dentition, onychodystrophy, and hyperkeratosis. There is only one published case of associated gastrointestinal abnormalities. We report a patient with Rothmund-Thomson syndrome with annular pancreas and duodenal stenosis.

Abstract
One year after a normal birth a girl developed large, flat and net-like telangiectasias and erythema with hyper- and depigmentation (poikiloderma), at first in the face and later on the limbs, sparing the trunk. There was increased light sensitivity of the affected areas. At 3 years and 8 months of age her height was diminished (3rd percentile; height 104 cm, weight 15 kg) and she had a deep nasal root and bradydactylia. These cutaneous and extracutaneous abnormalities correspond to the spectrum of Rothmund-Thomson syndrome which has a wide clinical heterogeneity. The family history for this condition was negative.

Abstract
Rothmund-Thomson syndrome is a rare, inherited disorder characterized by poikilodermatous skin changes that appear in infancy. The inheritance is autosomal recessive. Patients exhibit variable features including skeletal abnormalities, juvenile cataracts, and a higher than expected incidence of malignancy. This extensive review of the world literature clarifies aspects of the inheritance, incidence of characteristic features, and malignant potential of this disease. Insight into its origin is provided through a review of the clinical and in vitro studies of endocrine function and possible DNA repair abnormalities.

Abstract
We report on an 8-year-old girl with manifestations of congenital poikiloderma during her first year of life. Macroscopically, there was reticular teleangiectasia on cheeks and thighs, generalized de- and hyperpigmentation, dry skin with pityriasiform scaling and milia as a result of former blister formation. Histologically and ultrastructurally cytoid bodies, probably of keratinocyte origin, were observed. Associated findings were leucocytopenia, hyperlipoproteinaemia, spastic ataxia and lack of teeth. There is consanguinity in the family, but 3 sisters, the parents and the ancestors were completely healthy. Because of transient blister formation on the face, upper arms and elbows we would like to classify our case as Brain syndrome.

Abstract
Since birth an 8-year-old girl had a rash on both cheeks, consistent clinically and histologically with poikiloderma. She also had visual impairment to the extent of light perception only, due to microthalmia and dense scleralization of the corneas. These features were considered consistent with a diagnosis of Rothmund-Thomson syndrome.

Abstract
A patient, 21-year-old japanese man demonstrating many of the changes seen in the Rothmund-Thomson's syndrome is presented. In particular the hyperkeratosis palmo-plantar hyperkeratosis and warty hyperkeratosis on the hand and feet are prominent clinical features in this patient. The literatures describing hyperkeratosis in the Rothmund-Thomson's syndrome are reviewed and the clinical feature as well as diagnostic value of the hyperkeratosis is discussed.

Abstract
Two siblings with poikiloderma, short stature and other abnormalities are described. They were originally reported as having Morquio syndrome; subsequently, mucopolysaccharidosis was excluded biochemically and they were classified as 'a newly recognized syndrome of connective tissue dysplasia'. It is now clear that their disorder is the Rothmund-Thomson syndrome (RTS).

Abstract
This report describes a boy with Rothmund-Thomson syndrome associated with trisomy 8 mosaicism. The patient presented with typical features of Rothmund-Thomson syndrome but some of the features often seen in trisomy 8 mosaics were also observed in him. The possibility that the two disorders might share a common pathogenesis is postulated.

Abstract
Poikiloderma is characterized by the syntopy of diffuse atrophy, leukomelanodermia and teleangiectasia. We differentiate between symptomatic, idiopathic and congenital forms. Congenital poikiloderma shows 3 decisive features: early appearance, familial occurrence, and various associated congenital malfomations. On account of distinctive features - such as the consanguinity of the parents, cataracts, leukoplakia, bullas, and verrucous keratoses - we can distinguish between 5 biotypes of congenital poikiloderma, which are named after their first observers: Rothmund's, Thomson's, Zinsser's, Brain's and Dowling's syndrome.
