We report two cases of congenital curvilinear palpable hyperpigmentation on the posterior aspect of bilateral legs in male infants. These lesions appeared shortly after birth and mimicked child abuse with looped cord or postinflammatory hyperpigmentation. ⋯ One of the boys also had severe global developmental delay with abnormal findings from magnetic resonance imaging of the brain. We believe that these lesions represent a new type of congenital hyperpigmentation that we termed "congenital curvilinear palpable hyperpigmentation." Although these lesions do not follow the lines of Blaschko, they may also be associated with neurologic and developmental abnormalities.

Langerhans cell histiocytosis presenting as blueberry muffin baby.
Blueberry muffin baby is a descriptive term for purpuric lesions reflective of extramedullary hematopoeisis. The clinical lesions most commonly result from intrauterine infections, such as rubella and cytomegalovirus, and less commonly with malignancy and hematologic disorders. Langerhans cell histiocytosis is a clonal proliferation of dendritic histiocytes in the skin. ⋯ Skin biopsy showed a dermal proliferation of histiocytes staining positive for S100 and Cd1a. Pediatric bone surveys, chest radiographs, and computed tomography scans of the head were normal. Six months later, the skin lesions had resolved, but radiographs revealed lytic bone lesions of the right tibia, right ilium, and left pubic ramus, consistent with skeletal Langerhans cell histiocytosis.

Infantile pedal papules are symmetric, painless, flesh-colored nodules on the medial aspects of an infant's heels. Although the medical literature suggests they are uncommon, a survey of 269 newborns and 189 infants indicates the incidence of these to be 5.9% in newborns and 39.4% in infants.

ReviewCorticosteroids: options in the era of steroid-sparing therapy.
Topical corticosteroids remain the most commonly used topical treatments for inflammatory dermatoses, including psoriasis and atopic dermatitis. Topical corticosteroids are available in a variety of vehicles-creams, ointments, lotions, gels, and, more recently, foam. The vehicle used can substantially affect the individual agent's clinical action, potency, and acceptability to the patient. ⋯ Judicious use includes short-term, appropriate application as initial monotherapy or in combination strategies with other therapeutic agents that ideally possess complementing mechanisms of action. Examples include pulsing with high-potency topical corticosteroids and combination regimens with other topical agents such as topical calcineurin inhibitors, calcipotriene, or tazarotene. Appropriate education of patients and caregivers alike will facilitate the optimal use of these medications.

ReviewDecision points for the initiation of systemic treatment for psoriasis.
Psoriasis has a tremendous effect on health-related quality of life. Phototherapy and systemic treatments are used for patients with more debilitating (physically and emotionally) forms of the disease. These treatments can be extremely effective but can also have potentially significant adverse effects. ⋯ Here, we present a diagnostic algorithm and a formal measure, the Koo-Menter Psoriasis Instrument (KMPI), to aid in identifying patients that would benefit from systemic therapy. In addition, the KMPI can be used to document and justify treatment decisions for health care payers. While the decision to undertake systemic treatment and the choice of specific treatment plan must ultimately be made mutually by the patient and physician, these tools are designed to provide information that will be valuable in these determinations.
