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.

Aplasia Cutis Congenita (Epitheliogenesis Imperfecta) in Swine: Observations from a Large Breeding Herd

Epitheliogenesis imperfecta has been reported in several animal species, and its inheritance is suspected to be autosomal recessive. This term has been used to describe two different diseases, namely epidermolysis bullosa and aplasia cutis congenita, which are both grossly characterized by an absence of epidermis or mucosal epithelium and are most frequently reported on the distal limbs and oral cavity. Epitheliogenesis imperfecta has been described in swine, but the literature on the subject is scarce. To better characterize this condition, 70 piglets with congenital skin defects macroscopically compatible with epitheliogenesis imperfecta were examined. In all but 1 case, only 1 piglet per litter was affected. Of the affected piglets, 65 (93%) were male, suggesting a sex-related problem. More than half of the piglets had multiple skin lesions. All defects were located on the caudal half of the body, and none was found in the oral cavity. Most lesions were characterized by an absence of epidermis and part of the dermis and adnexae. Adnexal dysplasia was also observed at several sites, both with and without epitheliogenesis imperfecta, suggesting a developmental problem. Fluid-filled, congenital subcutaneous bullae were noted grossly on 7 piglets; their relationship, if any, with epitheliogenesis imperfecta remains unknown. As the term epitheliogenesis imperfecta has been used in cases of epidermolysis bullosa, the term aplasia cutis congenita seems to be more appropriate to describe these lesions in swine.

Early congenital syphilis and erythema multiforme-like bullous targetoid lesions in a 1-day-old newborn: detection of Treponema pallidum genomic DNA from the targetoid plaque using nested polymerase chain reaction

A 1-day-old male newborn was born with respiratory distress, low birth weight, hepatosplenomegaly, and bullous targetoid skin lesions over the face, back, buttocks, and extremities. A diagnosis of early congenital syphilis was made based on a treponemal serologic test. Pathologic examination of the skin lesion showed scattered dyskeratotic cells in the epidermis and interface dermatitis consistent with erythema multiforme. No spirochete could be found in the skin sections staining with Warthin-Starry stain. Using nested polymerase chain reaction, treponemal genomic DNA fragments encoding DNA polymerase I were detected.

Congenital poikiloderma with unusual hypopigmentation and acral blistering at birth

Congenital poikiloderma is an uncommon hereditary disorder. It has been reported in association with various syndrome. No case has previously been reported from this environment. We report a case of congenital poikiloderma in a two and a half year old female Nigerian associated with unusual generalised hypopigmentation and acral blisters at birth. The child subsequently developed macular hyperpigmentation on an erythematous background and atrophy of the skin. Although she had some features which were suggestive of Rothmund-Thomson syndrome (RTS), the presence of hypopigmentation at birth, along with acral blistering, was noted to be peculiar to this child. We, therefore, feel that this case presents a distinct variant of congenital poikiloderma that has not been described previously.

Symmetrical erosions in a neonate: a case of neonatal sucking blisters

Neonatal sucking blisters appears as unilateral or bilaterally symmetrical bullae or erosions involving the distal upper extremities at birth. They represent minor self-inflicted trauma, presumably the result of a vigorous intrauterine sucking reflex. Recognizing this benign self-limited condition avoids unnecessary tests and alleviates anxiety on the part of the infant's family and physicians.

A new case of extensive congenital erosions and vesicles healing with reticulate scarring

Congenital erosions and vesicles that heal with reticulate scarring comprise a new entity first described in 1985 in 3 girls aged 3, 5 and 6 years. Two years later, an 8-year-old boy in whom the skin lesions were accompanied by neurological disorders was described, as in one of the patients described in the 1985 study. In 1990, similar findings were reported in a neonate, and recently the 7th case has been reported in the American literature. We describe an 8-month-old infant born with cutaneous lesions that subsequently formed reticulate scars peculiar to this clinical entity, which is characterized by variable clinical and histological expression.

Poikiloderma of Theresa Kindler: report of a case with ultrastructural study, and review of the literature

Kindler's syndrome occurred in a 13-year-old boy with parental consanguinity. The patient had acral congenital blistering and photosensitivity, both regressive, at 12 years of age, together with diffuse progressive poikiloderma, marked cutaneous atrophy, mild hyperkeratosis of the palms, gingival hypertrophy and fragility, and anal stenosis. The ultrastructural study of bullae induced by rubbing showed clefts in three levels of the dermoepidermal junction zone. A review of 14 cases in the literature consistent with Kindler's syndrome showed this to be a definite clinical entity among the other bullous hereditary poikilodermas. In two cases, ultrastructural studies showed intraepidermal, junctional, and dermal cleavage. This syndrome must be differentiated from congenital epidermolysis bullosa, Weary's syndrome, and the other bullous hereditary poikilodermas.
