A Case of Bullous Rash Apparently Triggered by Meningococcal and Rotavirus Vaccines in an Infant: Focus on Infantile Bullous Pemphigoid

Bullous pemphigoid (BP) is an autoimmune bullous disease and is a rare condition in childhood. Acquired tense acral bullae and fixed urticarial annular lesions on the trunk are diagnostic clues of infantile BP. Diagnosis is supported by immunosorbent assay (IgG anti-BP180 and BP230) and direct immunofluorescence (linear deposition of IgG at the dermo-epidermal junction). Topical and/or systemic corticosteroids are the first-line treatment. The prognosis is good with a self-limited clinical course. Differential diagnoses include impetigo and other bullous diseases in children, such as dermatitis herpetiformis, linear IgA bullous dermatosis and erythema multiforme. The etiopathogenesis is still unknown, and the role of antigen stimuli such as infections, drugs and vaccination is still debated

Melorheostosis and Osteopoikilosis Clinical and Molecular Description of an Italian Case Series

Melorheostosis (MEL) is an uncommon, sclerosing disease, characterised by hyperostosis of long bones, resembling the flowing of candle wax. The disease is sporadic and the pathogenesis is still poorly understood. Occasionally, the same family can include individuals with MEL and Osteopoikilosis (OPK), a disease characterised by multiple round foci of increased bone density. LEMD3 gene mutations are related to OPK and Buschke–Ollendorff Syndrome, a genetic condition in which an association between MEL, OPK and skin lesions is observed. In rare cases, LEMD3 mutations and recently mosaic MAP2K1 gene mutations have been correlated to MEL suggesting that somatic mosaicism could be causative of the disease. In this study, we described the clinical, radiological and molecular findings of 19 individuals with MEL and 8 with OPK and compared the results to the medical literature. The molecular analyses of this case series corroborate the available data in the medical literature, indicating that LEMD3 germline mutations are not a major cause of isolated MEL and reporting five further cases of OPK caused by LEMD3 germline mutations

Cutaneous Mastocytosis Exacerbated by Pinworms in a Young Boy

Cutaneous mastocytosis in children has an indolent course and undergoes spontaneous regression. Many triggering factors may cause mast cell degranulation and clinical manifestations. Knowledge of these factors is important for patients and their families. We report a case of exacerbation of urticaria pigmentosa due to mast cell degranulation caused by Enterobius vermicularis, which has not been reported before as a triggering factor

Novel p.Glu519Gln missense mutation in ST14 in a patient with ichthyosis, follicular atrophoderma and hypotrichosis and review of the literature

Autosomal recessive congenital ichthyosis (ARCI) is a clinically and genetically heterogeneous group of genodermatoses characterized by disorders of cornification. ARCI11 (MIM #602400) includes two syndromes caused by mutations in the ST14 (suppression of tumorigenicity 14) gene: IFAH (autosomal recessive congenital ichthyosis, follicular atrophoderma and hypotrichosis) and ARIH (autosomal recessive ichthyosis and hypotrichosis). All the reported ARCI11 cases so far belonged to consanguineous Turkish or Arab families]. We describe a novel p.Glu519Gln missense mutation in a patient affected by IFAH from a non consanguineous Rumanian family
