RESUMO
Aim: To report an ocular juvenile xanthogranuloma (JXG) case presented with buphthalmos, corneal cloudiness, and normal intraocular pressure (IOP) in the neonatal period and treated with Ahmed glaucoma valve (AGV) implantation. Background: JXG is a rare disorder predominantly seen in infants, but the neonatal presentation is extraordinary. Although spontaneous hyphema is a common presenting sign in JXG, buphthalmos and corneal opacity in the neonatal period were reported only in one case, which had high IOP values at presentation. Case presentation: Sixteen-day-old male patient presented with buphthalmos, diffuse corneal clouding, and 11 mm Hg of IOP value in the right eye. IOP increased to 28 mm Hg three weeks later, and spontaneous hyphema developed, which did not respond to antiglaucomatous medications and topical corticosteroids. AGV was implanted, and the IOP decreased to 13 mm Hg postoperatively. In the follow-ups, numerous firm yellowish nodules were noticed on the patient's skin during the examination under general anesthesia. Histopathological examination of the skin nodules was compatible with the diagnosis of JXG. Lens subluxation and phacodonesis were developed during the follow-up and were managed with pars plana lensectomy. After a silent period of 3 months, epithelial ingrowth was determined around the side port entrance. Unfortunately, the ingrowth did not respond to cryotherapy and resulted in phthisis bulbi. Pathological evaluation of the enucleated phthisic eye revealed posterior segment involvement. Conclusion: Ocular JXG can be present with buphthalmos, corneal opacity, and normal IOP values without any skin lesions in the neonatal period. Neonatal presentation of JXG may be associated with limited medical therapy response and aggressive disease course. Clinical significance: This case report introduces the second ocular JXG case, which presented with buphthalmos and corneal cloudiness, and the third pathologically proven posterior segment involvement of JXG in the literature.

RESUMO
Acute generalized exanthematous pustulosis (AGEP) is seen uncommonly in children and sometimes shows atypical clinical features in this population. Patch testing can be used effectively in children for the confirmation of the culprit drug in cases of multiple drug use. Here, we report a rare, pediatric case of ceftriaxone-induced AGEP confirmed by patch testing with subsequent recurrence of the skin eruption.

BACKGROUND: Autoimmune bullous disorders (AIBDs) are a heterogeneous group of diseases which are rarely seen in children. Studies concerning the immunobullous diseases in pediatric patients are scarce. AIMS AND OBJECTIVES: In this study, we aimed to investigate the clinical features and treatment outcomes of AIBDs in children. MATERIALS AND METHODS: The electronic records of the patients in our AIBDs outpatient clinic were retrospectively reviewed. All cases diagnosed before the age of 16 years were included in the analysis of clinical features, treatment outcomes, and follow-up data. RESULTS: Of the 196 patients with immunobullous diseases, 9 (4.6%) were diagnosed before the age of 16 years. Mean age of the patients at the time of diagnosis was 7.72 ± 5.66 years. Among nine patients, linear immunoglobulin A disease (LAD), pemphigus vulgaris (PV), and bullous pemphigoid (BP) were seen in 5, 2, and 2 children, respectively. All patients were treated with at least two systemic agents (including methylprednisolone, dapsone, methotrexate, salazopyrine, intravenous Ig [IVIg], and rituximab) leading to clinical remission in all of them after a mean period of 31.77 ± 27.99 months. CONCLUSION: In line with earlier studies, LAD was the most common immunobullous disease and in general, associated with a favorable response to dapsone. This study was noteworthy in that the patients with PV and BP demonstrated a relatively more recalcitrant course, requiring rituximab and IVIg for remission, respectively. Overall, patients had a good prognosis.
RESUMO
Inherited mutations in desmosome genes can present with a spectrum of skin, hair and cardiac abnormalities. Here we describe a 4-year-old Turkish boy with a cardio-cutaneous syndrome resulting from compound heterozygous nonsense mutations in desmoplakin. Early recognition of such cases by clinical awareness of the dermatological features and molecular diagnostics can improve patient management through early cardiac support, although the risk of cardiomyopathy and arrhythmias poses a major health concern.

Atopic dermatitis (AD) is a heterogeneous disease with regard to clinical phenotype and natural history. We investigated T cell subtypes and cytokine responses in peripheral blood and skin lesions of AD patients with various sensitivities. Immunological studies were performed in 27 subjects: 9 house dust mite (HDM)-sensitized; 6 subjects with sensitizations other than HDM; 7 non-allergic AD patients and 5 healthy controls. Among those, skin biopsy samples of 13 subjects were evaluated for immunohistochemical analyses, as well. The mean age was 8.93±5.17 years. HDM-allergic AD emerged as a distinct immunologic phenotype, with higher production of interleukin (IL)-4, -5, -2 both at rest and when stimulated by Der p1 or SEB along with higher Th17. As for TH17 cell percentage, it was increased in all AD groups compared to healthy controls, while HDM-allergic group was distinguished with a significantly lower production of IL-17. Patients with sensitizations other than HDM were mostly similar to non-allergic AD, with increased Th17 and CD4+CD69+interferon-gamma (IFN-γ)+ T cells percentage. The biopsy of lesional skin showed that HDM-allergic AD had lower IFN-γ and IFN-γ co-expressing CD8+ T cells compared to patients with other sensitizations (p=0.03 and p=0.04, respectively). Among the HDM allergic patients, pairwise comparison of lesional versus non-lesional skin revealed higher CD4+ T cells numbers, expression of forkhead box P3 (Foxp3) and T-cell-specific transcription factor (T-bet) (p=0.018, p=0.018, p=0.018, respectively). HDM-allergic AD is a distinct subtype with a predominant skewing in Th2 and higher Th17 cell percentage along with a blunted Th1 response in the skin, all of which may have therapeutic implications.

Papillon-Lefèvre syndrome is an autosomal recessive genodermatosis typically manifesting with the constellation of palmoplantar keratoderma and progressive early-onset periodontitis. The cutaneous phenotype can be strikingly psoriasiform, possibly posing a diagnostic challenge. This rare disorder is caused by loss-of-function mutations in the CTSC gene, which encodes cathepsin C. We report six patients with Papillon-Lefèvre syndrome from five consanguineous Turkish families, in whom genetic analysis of the CTSC gene revealed four recurrent mutations (c.415G>A; c.1015C>T; c.1019A>G; and c.103-105delCTG) and a novel missense mutation (c.117G>T) in the homozygous state.

Mycosis fungoides (MF) simulates a variety of dermatologic disorders histopathologically and clinically, well deserving the designation of a great mimicker. Interstitial MF is a rare, but well-recognized histopathological variant resembling the interstitial form of granuloma annulare or the inflammatory phase of morphea. From a clinical standpoint, MF can have a wide array of manifestations, including an anecdotal presentation with lesions clinically suggestive of lichen sclerosus (LS). We herein report a 25-year-old man with a history of patch-stage MF who later developed widespread LS-like lesions histopathologically consistent with interstitial MF. In some biopsies, additional features resembling LS were discerned. We think that our case might represent a unique variant of interstitial MF presenting with LS-like lesions. The diagnostic challenge arising from this uncommon presentation is discussed together with review of the literature.

Intravascular/intralymphatic histiocytosis (IV/ILH) is a rare, reactive cutaneous condition, with uncertain pathogenesis. It may be associated with various inflammatory and neoplastic diseases. Although the clinical presentation is various, the biopsies reveal dilated vessels, mostly lymphatics, containing aggregates of histiocytes within their lumina. We described 3 cases of IV/ILH with different clinical presentations. In the first case, the patient presented with lymphedema in the genital region without any underlying disease. However, the second and third cases had reticular erythematous skin lesions. The second case had common variable immunodeficiency disease, rheumatoid arthritis, inflammatory bowel disease, and a history of a lymphoproliferative lesion. The third case had metal prostheses at both his right and left knees. In all these 3 cases, histopathologic and immunohistochemical findings were similar to each other and to those cases reported in the literature. In addition, the third case was admixed with reactive angioendotheliomatosis. In the second case, the endothelium of the ectatic vessels expressed CD31 and CD34, but not D2-40/podoplanin, pointing out that these vessels were blood vessels rather than lymphatics, differing from the other 2 cases. In conclusion, we believe, the most convincing statement about IV/ILH is that it is not a distinct clinicopathologic entity, but a histopathologic feature found as a part of a constellation of inflammatory changes or many other conditions.

BACKGROUND: Poikiloderma with Neutropenia (PN) is a rare autosomal recessive genodermatosis caused by C16orf57 mutations. To date 17 mutations have been identified in 31 PN patients. RESULTS: We characterize six PN patients expanding the clinical phenotype of the syndrome and the mutational repertoire of the gene. We detect the two novel C16orf57 mutations, c.232C>T and c.265+2T>G, as well as the already reported c.179delC, c.531delA and c.693+1G>T mutations. cDNA analysis evidences the presence of aberrant transcripts, and bioinformatic prediction of C16orf57 protein structure gauges the mutations effects on the folded protein chain. Computational analysis of the C16orf57 protein shows two conserved H-X-S/T-X tetrapeptide motifs marking the active site of a two-fold pseudosymmetric structure recalling the 2H phosphoesterase superfamily. Based on this model C16orf57 is likely a 2H-active site enzyme functioning in RNA processing, as a presumptive RNA ligase. According to bioinformatic prediction, all known C16orf57 mutations, including the novel mutations herein described, impair the protein structure by either removing one or both tetrapeptide motifs or by destroying the symmetry of the native folding.Finally, we analyse the geographical distribution of the recurrent mutations that depicts clusters featuring a founder effect. CONCLUSIONS: In cohorts of patients clinically affected by genodermatoses with overlapping symptoms, the molecular screening of C16orf57 gene seems the proper way to address the correct diagnosis of PN, enabling the syndrome-specific oncosurveillance. The bioinformatic prediction of the C16orf57 protein structure denotes a very basic enzymatic function consistent with a housekeeping function. Detection of aberrant transcripts, also in cells from PN patients carrying early truncated mutations, suggests they might be translatable. Tissue-specific sensitivity to the lack of functionally correct protein accounts for the main cutaneous and haematological clinical signs of PN patients.

OBJECTIVE: To report on a 10-year-old boy with KID syndrome who presented with a new onset unilateral toe walking. METHOD: This patient's equinus contracture was evaluated clinically. The patient underwent to surgical lengthening of Achilles tendon. After the surgery, the patient was placed in a short-leg walking cast for 6 weeks and then received a rehabilitation programme involving stretching exercises. RESULTS: Successful heel-to-toe gait was achieved in 3 weeks following surgery and rehabilitation. CONCLUSION: Surgical intervention and postsurgical rehabilitation may be indicated for children who present with toe walking attributed to contracture in the Achilles tendon.

Phacomatosis pigmentovascularis (PPV) is a group of syndromes comprising coexistent vascular and pigmentary nevi, which is first classified into five subtypes and then further categorized according to the absence or presence of associated systemic findings as type (a) and (b), respectively. This case report is of an 11-year-old Turkish girl with extensive vascular nevus and nevus spilus. Because of coexistent scoliosis, the patient represents an example of PPV type IIIb. Including the present case, a total of eight cases of PPV type IIIb have been reported to date. The case is discussed in view of the new classification proposed by Happle.
