P6433 Propanolol for a pelvis syndrome-associated hemangioma Shivani Bashiyan, MBBS, MD, Wake Forest University School of Medicine, Winston-Salem, NC, United States; Gil Yosipovitch, MD, Wake Forest University School of Medicine, Winston-Salem, NC, United States; Shawn Kwatra, MD, Wake Forest University School of Medicine, Winston-Salem, NC, United States PELVIS syndrome is a rare form of segmental hemangioma associated with genital and systemic abnormalities. In 2006 Girard et al proposed the acronym PELVIS to tie together the syndrome composed of the following abnormalities: perineal heman- gioma, external genital malformations, lipomyelomeningocele, vesicorenal abnor- malities, imperforate anus and skin tag. We report the case of a male infant with ulcerated segmental hemangiomas in the perineal area misdiagnosed at birth as diaper rash. Atypical external genitalia was noticed at birth. Examination revealed a bifid scrotum, a midshaft hypospadias with chordee, and leftward deviation of the penis with abnormal foreskin. No vascular lesions were noted at this time. The patient eventually presented at 3 months of age with a large, painful vascular lesion in the perineal area extending anteriorly to the genitals, bifurcating the scrotum and running posteriorly to the sacral area and buttocks with ulceration in parts. This lesion started at birth as a red patch in the sacral area and was misdiagnosed and treated as a diaper rash. Magnetic resonance imaging of the lumbar spine revealed the presence of spinal cord and vesicorenal abnormalities. Oral propranolol therapy was started, which gradually decreased the size and ulceration of the hemangioma. Multistep surgical repair was performed for the external genital malformations and tethered spinal cord. This report emphasizes the importance of careful examination and correct diagnosis of suspicious lesions at birth as these can be associated with other systemic anomalies that may lead to long-term complications. Approximately 10% of infantile hemangiomas are located in the perineal area. Hemangiomas occurring at this site are more prone to ulceration due to irritation from stool, urine, friction and maceration. The first case of perineal hemangioma associated with systemic and genital anomalies was reported in 1986 by Goldberg et al, and only a handful of cases have been reported since this time. We also confirm the successful use of oral propranolol in treating ulcerated segmental hemangiomas in PELVIS syndrome. Commercial support: None identified. P6302 Recognizing and managing eczematous id reactions to molluscum con- tagiosum virus in children Elena Netchiporouk, MD, Elena Netchiporouk, Laval, Quebec, Canada; Bernard Cohen, MD, Bernard A. Cohen, Baltimore, MD, United States Molluscum contagiosum (MC) is a self-limiting cutaneous viral eruption that is very common in children. MC infection can trigger an eczematous reaction around molluscum papules known as a hypersensitivity or an id reaction. In addition, a hypersensitivity reaction can occasionally occur at sites distant from the primary molluscum papules. These eczematous reactions are often asymptomatic or minimally pruritic. We believe that id reactions represent an immunologically mediated host response to MC virus and a harbinger of regression. Therefore, these reactions often do not require treatment other than emollients. Moreover, topical steroids or immunomodulators may suppress this process and potentiate the spread of the primary MC infection. However, in symptomatic patients, treatment should not be withheld and short-course treatments of topical corticosteroids may be used. In this case series, we describe 3 cases of hypersensitivity reactions in otherwise healthy children with MC. We hope that our report will make clinicians more aware of this common eczematous response to MC and will improve the management and counseling of these patients and their parents.

Two studies were performed in order to investigate noninvasively physiologic skin parameters, biochemical skin composition, and skin surface maturation for characterizing neonatal skin in comparison to different children age groups and adult’s skin. Methods: The first study was performed in healthy volunteers (n ¼ 108) of 6 age groups (n ¼ 18/group: newborns (1-15days), five-week, six-month, 1-2yrs, 4-5yrs and adults 20-35yrs). Biophysical parameters (TEWL, capacitance and surface pH) were measured on the volar forearms. In six subjects of each age group water- and bulk NMF-profiles were assessed with in vivo Raman spectroscopy (RS). D-squames were collected (n ¼ 6/group) and a clinical score of surface maturation was developed based on scanning electron microscopy (SEM) pictures: the electron microscopy isotropy (EMI) score. In the second study, D-squames were collected on 30 volunteers of the same age groups (excepted newborns) (n ¼ 6/group). SEM pictures were scored with the EMI score to validate surface maturation with age. Results: The newborns’ skin is quickly adjusting to the challenging postpartum environmental conditions. However, some functions such as SC water-binding properties continue to develop even beyond the neonatal period with an impact on skin surface organization. Semiquantitative analysis of skin surface isotropy based on the EMI score show a clear correlation between the age and the score. Conclusion: Neonatal and infant skin is mainly competent under basal conditions except SC water content and NMF components regulating the SC hydration level. A maturation of the skin surface is also observed with EMI scores probably related to the organization of the skin microanatomy after birth. Commercial support: None identified.

Methods: We present a 14-year-old male with history of hay fever and Crohn’s disease since he was 13 treated with infliximab and azathioprine. Despite treatment the patient developed an intense outbreak of Crohn’s disease with an abscess in the presacral area, starting treatment with adalimumab, teicoplanin, meropenem and metronidazole. He was admitted to for general malaise, abdominal pain, rector- rhagia, fever and appearance since 2 days ago of urticarial papules and nodules on the legs, which were painful on palpation. Results: The histologic features include diffuse infiltrates into the deeper dermis extending into the subcutaneous tissue composed of neutrophils and cells of monocytic-histiocytic appearance. The infiltrating cells were in part immature with round, oval or indented nuclei. Immunohistochemical study of these immature cells showed positive staining for myeloperoxidase. Routine blood cell count showed anemia (hemoglobin, 112 g/L) with elevation of white blood cells (18.85 3 10 9 /L) and neutrophilia (76.4%). Other laboratory evaluations showed elevated erythro- cyte sedimentation rate (101 mm/hr) and C-reactive protein. The remaining diagnostic tests showed no abnormalities. Treatment with methylprednisolone was started with disappearance of fever in 24 hours and progressive improvement of skin lesions. Discussion: Histiocytoid Sweet syndrome represents a histopathologic variant of Sweet syndrome, characterized by an infiltrate composed mainly of immature granulocytes, which can be misinterpreted as histiocytes. This histopathologic variant should not be mistaken with leukemia cutis or other inflammatory derma- toses that are histopathologically characterized by histiocytes interstitially arranged between collagen bundles of the dermis. Sweet syndrome is an unusual extra- intestinal manifestation of Crohn’s disease, especially the subcutaneous histiocytic variant. In the few cases reported, it is described in patients with underlying hematologic disorders or caused by several drugs, but very rarely in patients with inflammatory bowel disease. Conclusions: To our knowledge, this is the first case of subcutaneous histiocytoid Sweet syndrome in a pediatric patient. Commercial support: None identified. APRIL 2013 JAM ACAD DERMATOL AB177
