Neonatal sucking blister
Neonatal sucking blisters result from vigorous sucking on hand or forearm in utero. Clinically, one observes a tense, fluid-filled blister, which when ruptured forms an erosion. We report a female neonate with a sucking blister on the distal dorsal aspect of her left forearm. These benign bullae should be differentiated from other diseases of the newborn through their presentation, characteristic morphology, and self-limiting course
Becker's naevus and segmental naevus depigmentosus: An example of twin spotting?
A 12-year-old girl presented with a 1-year history of a Becker's naevus involving the right posterior thigh and gluteal area. In addition, three hypopigmented macules of naevus depigmentosus distributed in a segmental pattern on the medial aspect of the right posterior thigh had been present since birth. We suggest that their unusual coexistence in close proximity may represent an example of twin spotting
Tenascin-C Expression in Papulosquamous Disorders Other than Psoriasis in Pediatric Patients: An Epiphenomenon?
Background: Tenascin-C is a large extracellular matrix protein that is expressed in the basal membrane zone during embryonic development, tissue repair, and oncogenesis. In vitro studies suggest that proliferating epithelium induces the production of tenascin-C by mesenchymal cells
Lupus vulgaris in a pediatric patient: a clinicohistopathological diagnosis
Lupus vulgaris is the most common form of cutaneous tuberculosis which usually occurs in patients previously sensitized to Mycobacterium tuberculosis. We present a case of a 10-year-old boy who was diagnosed as lupus vulgaris clinically and histopathologically. He had well demarcated, irregularly bordered, pink, infiltrated plaques on his left cheek showing apple-jelly appearance on diascopy. The histopathological examination showed tuberculoid granulomas with Langhans type giant cells. The Mantoux reactivity was in normal limits, and no acid-fast bacilli was found in the lesion, either by direct stained smears or by culture. The lesions showed marked improvement on anti-tuberculosis treatment. We want to emphasize that histopathological examination has diagnostic value in lupus vulgaris in correlation with clinical appearance, when direct analysis or culture is negative
