Persistent cutaneous manifestations of hyperoxaluria after combined hepatorenal transplantation.

A 30-year-old woman with primary hyperoxaluria type I (PHI) developed livedo reticularis with overlying ulcerations on her legs 16 months after receiving a liver-kidney transplant. A skin biopsy of the lesion showed deposits of calcium oxalate. To our knowledge, there have been no reported cases of livedo reticularis in patients with PH1 after a combined liver-kidney transplant.

Response of ulcerated perineal hemangiomas of infancy to becaplermin gel, a recombinant human platelet-derived growth factor.

BACKGROUND: Hemangiomas of infancy are the most common tumors of childhood, and ulceration is the most common complication. Many treatments have been used for hemangioma ulceration, although none are uniformly effective. A recent report described the successful use of 0.01% becaplermin gel, a recombinant human platelet-derived growth factor, for an ulcerated hemangioma refractory to standard care. We sought to further assess the responsiveness of hemangioma ulceration to 0.01% becaplermin gel and to compare its cost to that of conventional modalities. OBSERVATIONS: We report a case series of 8 infants treated with becaplermin gel for ulcerated perineal hemangiomas of infancy. All infants were seen between January and June 2003 in the pediatric dermatology clinic at Texas Children's Hospital. Six female and 2 male infants were included. All of the hemangiomas were large (> or =6 cm(2)), and of superficial or mixed superficial and deep morphology. Rapid ulcer healing occurred in all patients within 3 to 21 days (average, 10.25 days). CONCLUSIONS: In this small series, 0.01% becaplermin gel was a safe and effective treatment for perineal hemangioma ulceration. The rapid healing achieved with 0.01% becaplermin gel allows a reduction in the risk of secondary infection, pain, and need for hospitalization, as well as in the costs that often accumulate from multiple follow-up visits and long-term therapy.
