RESUMO
We report the case of a 9-year-old girl with severe plaque psoriasis refractory to multiple topical and systemic therapies. Physical examination revealed extensive, erythematous plaques with overlying thick scales that covered more than 80% of her body surface area, which included the face, scalp, trunk, and limbs. Because of the severity of the disease and lack of treatment response to other systemic therapies, she was treated with ustekinumab. Three weeks after ustekinumab was initiated, her psoriatic lesions fully cleared.

FPrecursor T- or B-cell non-Hodgkin lymphoblastic lymphomas represent only a small fraction of pediatric cancer cases. Due to its rarity, the diagnosis of lymphoblastic lymphoma (LBL) in a pediatric patient is challenging, particularly if its manifestation is solely cutaneous. We describe the case of an infant with primary cutaneous B-cell LBL who was initially diagnosed by a primary care physician with an infectious etiology and consequently treated with topical and oral antibiotics. Subcutaneous nodules located on the head or neck of infants should raise suspicion for lymphoma and biopsy should be performed in order to rule out malignancy. A prompt diagnosis is imperative when considering the aggressive nature of LBLs. Expedited therapy has been known to help cease systemic involvement of primary cutaneous B-cell LBLs and encourage a more favorable outcome.
