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.

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
Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive genodermatosis characterized by poikiloderma and the variable presence of other features including skeletal and ocular abnormalities, ectodermal defects, and susceptibility to certain malignancies. We report a 40-year-old woman with known RTS who developed porokeratoses on her limbs in adulthood, an association that has not previously been reported. In addition, she had bilateral iris dysgenesis, which has only been described once before in RTS.

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
We report two unusual patients with Rothmund-Thomson syndrome (RTS), a rare genodermatosis. The first patient is a 5-year-old girl with congenital poikiloderma, photosensitivity, plantar punctate keratoderma, stunted growth and severe mental retardation. Plantar keratoderma associated with RTS has been reported only once. The second patient is a 21-year-old female presenting with rounded "moon" face, trunk obesity, coeliac disease, short stature and mild mental retardation. This is the first case of RTS associated with coeliac disease.

Abstract
BACKGROUND AND OBJECTIVES Intense pulsed light (IPL) systems are high-intensity light sources, which emit polychromatic light. Unlike laser systems, these flashlamps work with noncoherent light in a broad wavelength spectrum of 515-1,200 nm. These properties allow for great variability in selecting individual treatment parameters and adapting to different types of skin types and indications. The purpose of this article was to critically review international medical publications of the many indication in which IPL technology can be used, including our own evaluations and experiences. STUDY DESIGN/MATERIALS AND METHODS The range of therapeutic uses for high-intensity flashlamps was reviewed, ranging from benign cavernous hemangiomas, benign venous malformations, essential telangiectasias, leg telangiectasias, poikiloderma of Civatte, and port-wine stains to pigmented lesions, cosmetically undesired hypertrichosis, and facial rhydids. The relative benefits and risks were discussed in detail and compared with other laser systems. RESULTS Because of the wide spectrum of potential combinations of wavelengths, pulse durations, pulse frequency, and fluences, a great deal of experience is required when using IPL technology. Proper patient selection and critical diagnostics serve to keep the adverse effects of the treatment to a minimum. CONCLUSIONS The distinctive technical conditions involved combine to make IPL technology an alternative and auxiliary treatment option to existing laser systems and conventional therapies.

Abstract
Rothmund-Thomson syndrome (OMIM #268400) is a severe autosomal recessive genodermatosis: characterised by growth retardation, hyperpigmentation and frequently accompanied by congenital bone defects, brittle hair and hypogonadism. Mutations in helicase RECQ4 gene are responsible for a subset of cases of RTS. Only six mutations have been reported, thus, far and each affecting the coding sequence or the splice junctions. We report the first homozygous mutation in RECQ4 helicase: 2746-2756-delTGGGCTGAGGC in IVS8 responsible for the severe phenotype associated with RTS in a Malaysian pedigree. We report also a 5321 G-->A transition in exon 17 and the updated list of the RECQ4 gene mutations.

Abstract
Effective treatment of poikiloderma of Civatte is difficult. The ideal treatment combines elimination of both the vascular and pigmented components simultaneously. Treatment with a broad-spectrum noncoherent intense pulsed light source delivers multiple wavelengths with software-controlled pulse durations and sequencing that permit treatment of both vascular and pigmented lesions simultaneously. The objective of this study was to determine the response and side effects of treating this condition with intense pulsed light. In the study, 66 patients with typical changes of poikiloderma of Civatte on the neck were treated with intense pulsed light at various settings every 4 weeks until the desired improvement occurred. A 50 to 75 percent improvement in the extent of telangiectasias and hyperpigmentation was observed after an average of 2.8 treatments. The incidence of hypopigmentation was 5 percent. It was concluded that intense pulsed light is an effective mode of therapy for poikiloderma of Civatte. It seems to offer a reduction in both pigmentation and telangiectasia-associated erythema, with minimal side effects.

Abstract
Rothmund Thomson syndrome is a rare autosomal recessive skin disorder. The main clinical feature is poikiloderma appearing in early childhood associated with skeletal abnormalities. Early occurrence of malignancies is another relevant feature. Here we describe the clinical features of 2 patients with Rothmund Thomson syndrome who were investigated for the in vitro DNA repair capacities of blood cells following UVC radiation exposure. DNA excision repair, assessed with unscheduled DNA synthesis following UVC exposure, was decreased in both patients. Such a defect might explain the patients' sensitivity to sunlight and the relatively high risk of cancer associated with this syndrome.

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.

Abstract
We evaluated two patients with hereditary bullous poikiloderma. Both had acral bullae, generalized poikiloderma with prominent atrophy, and acral keratoses. One patient, with sporadic disease, had, in addition, urethral and subglottic stenoses, webbing of digits, and poor dentition. The other patient, whose disease was dominantly inherited, had koilonychia. The results of cutaneous histopathology, electron microscopy, and immunofluorescence mapping studies are presented. It is possible that Kindler syndrome and Weary's hereditary acrokeratotic poikiloderma are variants of the same disease.
