In 1989 Wilson Jones and Orkin first described tufted angioma, which has the unifying histologic feature of circumscribed angiomatous tufts and lobules within the dermis. Tufted angioma may take unusual forms clinically. We describe five children less than 3 years of age with tufted angiomas, demonstrating the variability of the morphology of this vascular tumor. Two of the lesions were congenital. Three presented as indurated, vascular-appearing plaques, one of which had associated hypertrichosis. One lesion appeared clinically compatible with a hemangioma of infancy, but continued to enlarge after the child was 32 months old. The remaining lesion was a nearly circumferential, soft tissue tumor of the left forearm with tortuous vessels and a smaller overlying vascular stain. All of these lesions demonstrated the characteristic histology of tufted angioma. The clinical and histopathologic differential diagnosis as well as treatment options for tufted angioma are reviewed.
We report five children with acute lymphocytic leukemia on maintenance chemotherapy who had Demodex folliculitis. None experienced complete clearing when treated with permethrin 5% cream. Topical metronidazole helped to lessen the eruption in four, but did not provide full clearing. The one child who was treated with sodium sulfacetamide 10%, sulfur 5% formulation had resolution of the eruption. We suggest that treatment of Demodex folliculitis in children with acute lymphocytic leukemia is more difficult than is suggested in the literature. Newer sodium sulfacetamide/sulfur formulations should be considered when treating this condition, particularly in children with acute lymphocytic leukemia.
We report a 9-month-old girl and a 4-year-old boy with acute febrile neutrophilic dermatosis (Sweet syndrome). Both children were febrile, had leukocytosis, and exhibited lesions characteristic of Sweet syndrome. Both had an antecedent infection. Our evaluation and long-term follow-up of these children failed to reveal evidence of underlying malignancy or a chronic systemic illness typically encountered in Sweet syndrome. Of interest, the 4-year-old boy responded to systemic corticosteroids with remission, whereas the 9-month-old infant experienced flaring of the disease on successive attempts to taper the systemic corticosteroids. Systemic corticosteroid usage was associated with alteration in behavior in the 4-year-old and transient growth retardation in the 9-month-old. In both patients, the adverse effects resolved after discontinuation of the corticosteroids.
We reported a series of three meningothelial hamartomas, one benign fibrous tumor, and one aplasia cutis congenita presenting with the hair collar sign and a coexistent vascular stain. Our series highlighted the importance of coexisting cutaneous markers found in the newborn period. The presence of a vascular stain and hair collar sign with or without a congenital scalp nodule should increase suspicion of an associated cranial dysraphism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
