White leaf macules are the earliest cutaneous manifestations of:
Addison's disease
Neurofibromatosis
Tuberous sclerosis - ANSWER Tuberous sclerosis
*White leaf macules are the earliest cutaneous manifestations of tuberous sclerosis, an
autosomal dominant syndrome. These macules vary in size and shape but most often
resemble a mountain ash leaflet. They may be difficult to see in a newborn infant and
can best be observed by examination with a Wood lamp. The lamp enhances the
contrast between the macule and normal skin. Normal infants may occasionally have a
single lesion, but the presence of one or more of these macules in an infant with
neurological problems strongly suggests the diagnosis of tuberous sclerosis. A skin
biopsy is not diagnostic. Indurated violet or red plaques or sharply defined
subcutaneous nodules on the buttocks, thighs, trunk, face, or arms are most likely
which of the following?
Intracutaneous hemorrhage
Sclerema
Subcutaneous fat necrosis - ANSWER Subcutaneous fat necrosis

trauma, shock, asphyxia, hypothermia, convulsions, hypothermia, toxemia of
pregnancy, meconium aspiration and intra-partum medication. One or several
indurated, violet or red plaques or sharply circumscribed subcutaneous nodules on the
buttocks, thighs, trunk, face, or arms may evolve. Most areas are resorbed gradually in
weeks to months if untreated. Residual atrophy or scarring is not common.

and are most often seen in black infants. If the lesion contents are smeared on a slide
and stained, they are found to be amorphous debris. These lesions are neither
infectious nor contagious, and require no treatment. Which of the following would one

Port-wine stain is an angioma composed of dilated and congested capillaries that lie just
beneath the epidermis.
At birth, the mark is pink but darkens to purple over time. It most often occurs on the
face and neck and is a permanent developmental defect. A port-wine stain is primarily a
cosmetic problem although it can be an indicator of a multisystem disorder such as
Sturge-Weber syndrome or Klippel-Trenaunay-Weber syndrome. Gradual thickening
and nodule formation can occur with port-wine stain, thus supporting the need for early
treatment in infancy and childhood. Scalded skin syndrome is caused by:
Serratia
Staphylococcus aureus
