  • An open-label study to evaluate sildenafil for the treatment of lymphatic malformations JOURNAL OF THE AMERICAN ACADEMY OF DERMATOLOGY Danial, C., Tichy, A. L., Tariq, U., Swetman, G. L., Khuu, P., Leung, T. H., Benjamin, L., Teng, J., Vasanawala, S. S., Lane, A. T. 2014; 70 (6): 1050-1057


    Lymphatic malformations can be challenging to treat. Mainstay interventions including surgery and sclerotherapy are invasive and can result in local recurrence and complications.We sought to assess the effect of 20 weeks of oral sildenafil on reducing lymphatic malformation volume and symptoms in children.Seven children (4 boys, 3 girls; ages 13-85 months) with lymphatic malformations were given oral sildenafil for 20 weeks in this open-label study. The volume of the lymphatic malformation was calculated blindly using magnetic resonance imaging performed before and after 20 weeks of sildenafil. Lymphatic malformations were assessed clinically on weeks 4, 12, 20, and 32. Both the physician and parents evaluated the lymphatic malformation in comparison with baseline.Four subjects had a lymphatic malformation volume decrease (1.0%-31.7%). In 2 subjects, despite a lymphatic malformation volume increase (1.1%-3.7%), clinical improvement was noted while on sildenafil. One subject had a 29.6% increase in lymphatic malformation volume and no therapeutic response. Lymphatic malformations of all 6 subjects who experienced a therapeutic response on sildenafil softened and became easily compressible. Adverse events were minimal.A randomized controlled trial will be necessary to verify the effects of sildenafil on lymphatic malformations.Sildenafil can reduce lymphatic malformation volume and symptoms in some children.

  • Rapidly Involuting Congenital Hemangioma Associated with Profound, Transient Thrombocytopenia PEDIATRIC DERMATOLOGY Rangwala, S., Wysong, A., Tollefson, M. M., Khuu, P., Benjamin, L. T., Bruckner, A. L. 2014; 31 (3): 402-404


      Rapidly involuting congenital hemangioma (RICH) is an uncommon, often high-flow vascular tumor that presents at birth and involutes within the first year of life. It is clinically and histologically distinct from infantile hemangioma, kaposiform hemangioendothelioma, and tufted angioma, the latter two being associated with Kasabach-Merritt phenomenon. We present a female infant with RICH and profound, transient thrombocytopenia and review the extent and clinical course of thrombocytopenia in the context of congenital vascular tumors.

  • Human Papilloma Virus is not Prevalent in Nevus Sebaceus PEDIATRIC DERMATOLOGY Kim, D., Benjamin, L. T., Sahoo, M. K., Kim, J., Pinsky, B. A. 2014; 31 (3): 326-330


    Nevus sebaceus (NS) is a common congenital cutaneous hamartoma that typically presents on the scalp and face at birth or in early childhood. Occasionally NS can be associated with the Schimmelpenning-Feuerstein-Mims syndrome, which presents with concomitant severe neurologic, skeletal, cardiovascular, ophthalmic, and genitourologic disorders. In a previous study, maternal transmission of the human papillomavirus (HPV) and infection of ectodermal stem cells by HPV was postulated to result in the development of NS. In this study we aimed to determine the incidence of HPV infection in pediatric NS samples to further clarify the potential link between HPV and the pathogenesis of NS. NS tissue samples (N = 16) were analyzed for HPV DNA using type-specific, real-time polymerase chain reaction (PCR) targeting HPV 6, 11, 16, and 18 and conventional PCR with modified general primers designed for broad-range HPV detection. The tissues were also histologically evaluated for evidence of HPV infection. HPV DNA was not detected in any of the NS tissue samples using PCR and HPV-associated histopathologic changes were absent in all 16 NS tissues. HPV infection is an unlikely etiologic cause of NS.

  • Sudden Onset Vision Loss in an 8-year-old Female with McCune-Albright Syndrome PEDIATRIC DERMATOLOGY Kim, D., Wysong, A., Lai, J., Alcorn, D. M., Benjamin, L. T. 2014; 31 (1): 80-82


      We describe a case of an 8-year-old girl with large irregular café au lait macules on the right cheek and right lower extremity presenting with sudden onset vision loss and found to have polyostotic fibrous dysplasia on imaging. The classic triad of McCune-Albright syndrome is discussed along with the importance of recognition in patients with partial presentation. This case also highlights a rare and potentially devastating neurologic complication of McCune-Albright syndrome, as well as the need for early diagnosis and continual surveillance in these patients.

  • Salivary gland choristoma (heterotopic salivary gland tissue) on the anterior chest wall of a newborn. Pediatric dermatology Aby, J. L., Patel, M., Sundram, U., Benjamin, L. T. 2014; 31 (1): e36-7


    Salivary gland choristoma (heterotopic salivary gland tissue) is a rare condition typically seen in the newborn period. This developmental heterotopia is generally nonprogressive, with little risk of malignant transformation. We present the second known reported case of a salivary gland choristoma located on the anterior chest wall. Knowledge of this rare entity will allow for accurate diagnosis and management of this benign anatomic variant.

  • Birthmarks of medical significance in the neonate SEMINARS IN PERINATOLOGY Benjamin, L. T. 2013; 37 (1): 16-19


    Birthmarks are commonplace and most pose no significant detriment to health. It is usual for some 'birthmarks' to manifest within the first weeks to months of life and are not necessarily seen at birth. This is attributed in large part to the maturation of neonatal skin and the deepening of skin color over time. With time, increased pigment production in the skin by melanocytes eventually highlight the differences between normal and abnormal hypopigmented and hyperpigmented anomalies of the skin. Birthmarks can be seen as an isolated skin condition or serve as an important diagnostic aid for other more significant disorders. This review details four of the most common birthmarks regularly encountered in the neonatal period by perinatologists, obstetricians and pediatricians. This review emphasizes their medical significance and highlights any associated underlying systemic disease or genetic syndrome.

  • Clear-Cell Papulosis: A Rare Entity That May Be Misconstrued Pathologically as Normal Skin PEDIATRIC DERMATOLOGY Wysong, A., Sundram, U., Benjamin, L. 2012; 29 (2): 195-198


    We describe a case of multiple, discrete, hypopigmented macules in the suprapubic and axillary region in a healthy 3-year-old girl. The lesions first appeared at approximately 9 months of age and increased in number over time. Initial histopathologic examination by an outside dermatopathologist at 1 year of age was reported as showing nonspecific histologic changes. A repeat biopsy at 3 years of age showed large intraepidermal clear cells that expressed CKAE1/CAM5.2, CK7, and BRST2. These findings are diagnostic for clear-cell papulosis, a rare condition that primarily affects children. Without great clinical and pathologic suspicion, this is a diagnosis that can often be overlooked because the histologic findings are virtually identical to those of normal skin.

  • Delineating Capillary Malformations in the Operating Suite Using White Eyeliner Pencil PEDIATRIC DERMATOLOGY O'Regan, G. M., Benjamin, L. T. 2011; 28 (6): 746-747


    Delineating the extent of capillary malformations in the operating suite can be challenging because of a variety of physiologic modifiers, including vasodilatation induced by anesthesia, reactive erythema, and filtering of colors with protective laser eyewear. The use of traditional surgical pens to mark the treatment field has limitations; we have found the use of a white eyeliner pencil to delineate lesions a contemporary technique that assists in identifying the target tissue intraoperatively.

  • Chronic rhinitis: a manifestation of leprosy. Ear, nose, & throat journal Camacho, I. D., Burdick, A., Benjamin, L., Casiano, R. 2011; 90 (9): E1-3


    Leprosy, or Hansen disease, is an infection that affects the mucous membranes of the respiratory tract and may manifest with nasal symptoms of chronic rhinitis, including nasal congestion, rhinorrhea, and intermittent epistaxis. We present a case of a woman diagnosed with leprosy as an incidental finding from a biopsy obtained during endoscopic sinus surgery for the management of chronic rhinitis. The diagnosis of leprosy should be considered in patients with nasal symptoms and presumptive chronic rhinitis who do not respond adequately to standard therapies.

  • Congenital Epidermolysis Bullosa Acquisita Vertical Transfer of Maternal Autoantibody From Mother to Infant ARCHIVES OF DERMATOLOGY Abrams, M. L., Smidt, A., Benjamin, L., Chen, M., Woodley, D., Mancini, A. J. 2011; 147 (3): 337-341


    Epidermolysis bullosa acquisita (EBA) is a rare, chronic, autoimmune bullous dermatosis that is caused by autoantibodies against the noncollagenous terminus of the ? chain of type VII collagen, resulting in decreased anchoring fibrils in the lamina densa. It classically presents with skin fragility and trauma-induced blisters that are particularly extensive over the distal aspect of the extremities and that heal with milia, dyspigmentation, and scarring, similar in presentation to dystrophic epidermolysis bullosa. Disease onset is typically in adulthood, although rare cases of childhood disease occur. To our knowledge, a case involving a neonate with congenital EBA has not yet been reported in the literature. We describe a newborn with transient EBA due to the passive transfer of maternal autoantibodies.A 2-day-old girl was evaluated for tense blisters and areas of denuded skin that had been present since birth. Her mother carried the diagnosis of EBA. The results of histopathologic analysis, immunofluorescence studies, and enzyme-linked immunosorbent assay confirmed the diagnosis of neonatal EBA. The patient improved with supportive therapy and has not required systemic intervention.Autoimmune neonatal bullous skin disease caused by placental transfer of maternal IgG autoantibodies is rare. It has been reported in neonates born to mothers with pemphigus vulgaris, pemphigus foliaceus, and gestational pemphigoid. To our knowledge, congenital EBA has not been previously reported. Vertically acquired congenital autoimmune blistering disorders appear to be self-limited and resolve with supportive therapy, concomitant with the presumed clearance of maternal autoantibodies from the neonate's circulation.

  • Successful acne management in Apert syndrome twins PEDIATRIC DERMATOLOGY Benjamin, L. T., Trowers, A. B., Schachner, L. A. 2005; 22 (6): 561-565


    Apert syndrome, or acrocephalosyndactyly, is characterized by craniosynostosis and early epiphyseal closure resulting in various deformities of the skull, hands, and feet. Typically a sporadic condition, autosomal dominant inheritance with complete penetrance has been known to occur. Most adolescents with the disorder are prone to the development of severe pustular facial and truncal acne, with extension to the upper arms and forearm. We report twin brothers with Apert syndrome who, after 2 years of standard management by their pediatrician, were referred for management of complicated acne. In our patients there were a constellation of findings consistent with the disorder and, of importance to this report, significant dermatological manifestations. On presentation, each brother was found to have acne vulgaris of a different stage. Our patients were refractory to conventional treatment for acne but one required and had a significant response to isotretinoin. The risk/benefit ratio in treating acne lesions with isotretinoin in a teenager with Apert syndrome is reviewed.
