Abstract
Darier's disease (DD) is an autosomal dominant inherited genodermatosis which is often under- or misdiagnosed. In the majority of cases, the disease manifests in adolescents or young adults with small brownish-yellow, warty, hyperkeratotic papules in multiple seborrheic areas of the body. Localized DD (LDD) is a clinical variant, first described by Kreibich in 1906; only a few cases are reported in the literature. We described the case of an aged woman presenting with LDD, and we review the literature on this subject.

Abstract
We report the unusual case of a plexiform fibromyxoma, occasionally assessed in a lithiasic gallbladder. The full thickness assessment of the gallbladder wall revealed an intra-mural, well demarked multi-nodular tumor (1 cm), consisting of a plexiform growth of spindle cells, included within a fibromyxoid stroma with a rich micro-vascular network. The tumor cells featured no nuclear atypia, nor mitotic activity. At the immunohistochemical profiling, the spindle shaped cells unequivocally featured vimentin, SMA, HHF35, collagen IV, and CD34; no cells expressed CD117, PDGFRA, CD10, desmin, GFAP, EMA, and S-100. Faint STAT6 nuclear expression was observed in isolated tumor cells. The molecular profiling did not revealed any CKIT and PDGFRA genes mutations. The uncommon site of the tumor presentation and its aberrant CD34 expression both confer to the reported case a unique place among the myxoid tumors of the gastrointestinal tract.

Abstract
Organ size regulation is a highly coordinated process involving complex mechanisms. Yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif, also known as WWTR1 (TAZ) have recently been linked to organ size determination and cell proliferation. Pilomatrixoma (PM) is a benign tumor of the adnexal appendages with a certain degree of differentiation toward the matrix of the hair follicle. PM presents as a dermal nodule that usually ranges from 0.5 to 2 cm, rarely exceeding 3 cm. We recently observed a case of unusual "giant" (6.5 cm) PM. Our hypothesis was that YAP and TAZ could be related to PM growth. We analyzed YAP and TAZ immunohistochemical expression in the giant and in ten usual size PMs in relation with tumor size and proliferation rate. YAP nuclear expression was remarkably higher in the giant PM in comparison with usual size PMs and statistically correlated, in a direct manner, with size and proliferation rate of PMs. Contrariwise, TAZ nuclear expression seemed stochastic. Our findings suggest that YAP could play a role in PM growth.

Abstract
BACKGROUND Treatment of bronchopulmonary dysplasia (BPD) remains as yet an unmet clinical need and recently stem cells have been proposed as a therapeutic tool in animal models. We investigated the role of amniotic fluid stem cells (AFS) in an adult rat model of hyperoxia lung injury. METHODS Fifty Sprague-Dawley rats were, at birth, randomly exposed to moderate hyperoxia or room air for 14 days and a single dose of human amniotic fluid stem (hAFS) or human Fibroblasts (hF), cells was delivered intratracheally (P21). At P42 animals were euthanized and lung tissue examined using histology, immunohistochemistry, PCR, and ELISA. hAFS cells characterization and homing were studied by immunofluorescence. RESULTS In rats treated with hAFS and hF cells 16S human rRNA fragment was detected. Despite a low level of pulmonary hAFS cell retention (1.43 ± 0.2% anti-human-mitochondria-positive cells), the lungs of the treated animals revealed higher secondary crest numbers and lower mean linear intercept and alveolar size, than those exposed to hyperoxia, those left untreated or treated with hF cells. Except for those treated with hAFS cells, moderate hyperoxia induced an increase in protein content of IL-6, IL-1β, as well as IF-γ and TGF-1β in lung tissues. High VEGF expression and arrangement of capillary architecture in hAFS cell group were also detected. CONCLUSIONS Treatment with hAFS cells has a reparative potential through active involvement of cells in alveolarization and angiogenesis. A downstream paracrine action was also taken into account, in order to understand the immunodulatory response.

Abstract
Fluoxetine shows controversial lung effects as it prevents pulmonary hypertension in adult rats but exposure during gestation causes pulmonary hypertension in neonatal rats. In the present study, we tested the null hypothesis that the antidepressant drug fluoxetine does not modify the development of bronchopulmonary dysplasia (BPD) in neonatal rats. Experimental categories included I: room air (controls) with daily injection of saline; II: room air with daily injection of 10 mg/kg fluoxetine, i.p., during two weeks; III: 60% oxygen with daily injection of saline; and IV: 60% oxygen with daily injection of 10 mg/kg fluoxetine, i.p., during two weeks. Hyperoxia resulted in significant reduction in alveolar density and an increase in pulmonary endocrine cells, as well as increases in muscle layer areas of bronchi and arteries. Fluoxetine treatment generated a further increase in muscularisation and did not significantly modify the hyperoxia-induced reductions in alveolar density and increases in the endocrine cells. In hyperoxia, Real-Time PCR showed a lower pulmonary expression of vascular endothelial growth factor (VEGF) with no significant changes in the expression of matrix metalloproteinases (MMP) 2 and 12. Fluoxetine did not affect VEGF or MMP-2 expression but it significantly increased MMP-12 mRNA in both normoxic and hyperoxic groups. Zymographic analysis of MMP-2 activity in bronchoalveolar fluid showed a significantly reduced MMP-2 activity in hyperoxia, while fluoxetine treatment restored MMP-2 activity to levels comparable with the normoxic group. In conclusion, our data show that fluoxetine may worsen bronchial and arterial muscularisation during development of BPD and may up-regulate MMP expression or activity.

Abstract
Triploidy occurs in about 1 to 3% of clinically recognizable pregnancies and is typically associated with growth restriction, craniofacial dysmorphisms and congenital anomalies. We report the case of a female fetus with prenatal diagnosis of complete triploidy, polysplenia, bilateral cleft-palate, horseshoe-kidneys and bilateral club-feet. Whereas bilateral cleft-palate, horseshoe-kidneys and bilateral club feet are known to be part of the triploidy-associated malformation spectrum, polysplenia, which usually occurs as part of the heterotaxia spectrum, has never been associated with triploidy. An amplification of the triploidy phenotype or a "double trouble".

Abstract
BACKGROUND Lichen simplex chronicus is a common skin disorder characterized by circumscribed, lichenified, pruritic plaque secondary to local repetitive trauma, notably rubbing and scratching. OBJECTIVE We describe a case of a squamous cell carcinoma arising in a patient with a long-lasting history of lichen simplex chronicus and discuss the potential role of the microenvironment in predisposing the malignant transformation. CONCLUSION Here we propose a hypothesis in which rubbing and scratching contribute to an excess of inflammatory mediators, which in turn may lead to alterations in the processes of keratinocyte proliferation and differentiation.

Abstract
Cantrell's pentalogy (CP) is a rare, mainly sporadic spectrum of congenital midline thoracoabdominal defects that includes sternal anomalies, ventral diaphragmatic hernia, partial absence of the pericardium, supraumbilical abdominal wall defects, and congenital heart malformations. The approximate incidence is 1 in 100 000, with a 2∶1 male predominance. A 25-year-old pregnant woman was referred to the Prenatal Diagnosis Unit of the University Hospital of Padua for multiple congenital malformations at 21 weeks of gestation. A level 2 ultrasound scan was performed and confirmed the presence of multiple anomalies compatible with the diagnosis of CP associated with complete ectopia cordis. Fetal autopsy furthermore revealed asplenia, which usually presents as part of the heterotaxia spectrum. To our knowledge, an association of CP and complete ectopia cordis with asplenia has never been reported so far.

Abstract
Congenital pulmonary airway malformations (CPAM) are a family of hamartomatous disorders due to the uncontrolled overgrowth of the terminal bronchioles. Congenital pulmonary airway malformations can co-exist with cardiovascular and/or urogenital malformations, but their association with thoracopulmonary malformations is extremely rare. We report the first case of CPAM type I, co-existing with tracheo-esophageal fistula and corpus callosum agenesis.

Abstract
A 41-year-old man presented with a 2-cm painful subcutaneous nodule in his right leg, which had been present for more than 10 years and was recently enlarging. Histologically, the tumor was composed of sheets and nests of cells with variable cytomorphology, including typical round/ovoid glomus cells with clear cytoplasm and well-defined borders, small cells, and spindle cells. Numerous medium to large vessels were present. Nodules with moderate to high cellularity, nuclear atypia, and frequent mitotic figures (42 per 50 high-power fields) were noted. Immunohistochemistry showed cytoplasmic and membranous expression of smooth-muscle actin, vimentin, and membranous expression of type IV collagen. Whereas superficiality, dimensions, and long-term follow-up may suggest classification as a symplastic or uncertain potential glomus tumor (GT), histological features and immunoprofile are indicative of malignant nodules developed in a typical GT. The follow-up has been negative for recurrence/metastases. A search of the literature revealed 17 cases of malignant GTs between 1995 and 2010, all fatal, of which 10 had skin as the primary site.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumour, is an uncommon benign vascular lesion characterized by small multiple, endothelial-lined, papillary structures with hyaline stalks. It appears to be a reactive condition involving excessive proliferation of endothelial cells in normal blood vessels or in vascular malformations, perhaps in response to blood vessel injury or thrombosis. The lesions are small, superficial, reddish-blue nodules, usually in the head, neck or hand. Distinction from pyogenic granuloma and angiosarcoma usually requires pathological examination. Complete surgical excision is the treatment of choice. Four cases affecting the finger are presented together with histological features.

Abstract
BACKGROUND Negative pressure wound therapy (NPT) has achieved widespread success in the treatment of difficult wounds. However, its effects are but partially explored, and investigations mostly concentrated at the wound-dressing interface; a detailed histological description of the evolution of wounds under NPT is still lacking. MATERIALS AND METHODS Subsequent punch biopsies of NPT-treated chronic wounds of human patients were analysed. Phenomena occurring in wounds were quantified by analysis of proliferating cells nuclear antigen (PCNA) (proliferating nuclei), CD31 (blood vessels), CD68p (macrophages) and CD45 (lymphocytes) stained slides. RESULTS Three layers were identified in day-0 wounds. Over time, under NPT, the layers behaved differently: the most superficial (1.5 mm) developed granulation tissue, constant in thickness, with high proliferation index, increased in blood vessels density and developed acute inflammation. Instead, the two deeper layers decreased in proliferation rate, maintained vessels density unchanged, were cleared of chronic inflammation and oedema and underwent progression towards stable tissue. DISCUSSION Indeed, while most research has focused on induction of superficial granulation tissue by NPT, deeper layers appear to be also affected, with relieving of chronic inflammation and tissue stabilisation. This may be an important and under-appreciated effect, playing a role in the known positive outcomes of NPT, such as better graft-taking rates.

Abstract
Several studies have reported that fetuses with intrauterine growth restriction (IUGR) and infants with low birth weight present increased intima/media thickness (aIMT) of the abdominal aorta wall compared with fetuses and infants appropriate for gestational age (AGA). Evidence suggested that aIMT might be related to inflammation, probably indicating a very early stage of future adulthood disease, such as atherosclerosis. We aimed to investigate histological findings in the abdominal aorta wall of one IUGR stillbirth in which ultrasound had detected aIMT. Microscopy observations of the abdominal aorta wall confirmed the intima thickening and detected condensation of the elastic fibers forming an evident internal elastic membrane and presence of inflammatory elements, such as macrophages, activated endothelial cells, and fibroblastoid cells. The present study highlights that IUGR associated with aIMT is related to inflammation, which might represent a very early sign of future adult lesions.

Abstract
BACKGROUND Scabies is a contagious infestation affecting subjects of all ages, races, and social conditions. OBJECTIVE We report a case of a 79-year-old man who developed a bullous pemphigoid-like eruption. He presented to our unit 4 months after the onset of symptoms. An autoimmune bullous disease was suspected. Direct immunofluorescence on a skin specimen and anti-desmoglein 1, anti-desmoglein 3, and anti-bullous pemphigoid antigen 180 were negative. Surprisingly, the histology of a skin lesion demonstrated the presence of scabies, which was successfully treated with benzyl benzoate 20%. CONCLUSION The diagnosis of bullous scabies should be considered for any bullous eruptions accompanied by papules and itching resistant to steroid treatment and with negative immunopathologic findings.
