Dermatoses in newborns.

Benign dermatoses in newborns must be distinguished from more serious disorders with cutaneous manifestations. Erythema toxicum neonatorum, transient neonatal pustular melanosis, sucking blister, miliaria and mongolian spots are among the many benign skin conditions that can occur in newborns. Recognition of these dermatoses allows the physician to proceed appropriately, reassure the parents and initiate further evaluation or treatment as necessary. To avoid adverse sequelae, special attention must be given to more persistent conditions and those with the potential for complications or malignant transformation. Consultation with a pediatric dermatologist, a plastic surgeon or a neurosurgeon may be necessary.

Extranodal spread of anaplastic large cell (CD30+) lymphoma presenting as a cutaneous perivascular infiltrate.

Cutaneous lesions of anaplastic large cell (CD30+) lymphoma (ALCL) typically present as solitary or multiple ulcerated nodules. This tumor is histologically characterized by a diffuse dermal and sometimes subcutaneous infiltrate composed of bizarre, pleomorphic, neoplastic cells that may be occasionally multinucleated. We report a case of extranodal spread of ALCL to the skin in a 2 1/2-year-old boy presenting as a widespread papular eruption that on biopsy showed lymphoma restricted to the perivascular and periadnexal dermis.
