| pubmed-article:9720685 | pubmed:abstractText | Cushing disease (CD) is a common cause of endogenous hypercortisolism in childhood. Its skin manifestations include striae, facial acne, hirsutism, acanthosis nigricans, fungal infections, hyperpigmentation and easy bruisability. We followed 36 children and adolescents with CD (14 boys and 22 girls), to define the natural history of skin disease in endogenous hypercortisolism. Physical examination and 24 hour urinary free cortisol (UFC) and 17-hydroxycorticosteroid (17-OHS) excretion values were obtained preoperatively and quarterly for 18 months. Preoperatively our patients exhibited purple subcutaneous striae (77.7%), steroid-induced acne (58.3%), hirsutism (63.7% of the 22 girls), acanthosis nigricans (27.7%), ecchymoses (27.7%), hyperpigmentation (16.6%), and fungal infections (11.1%). The levels of UFC and 17-OHS preoperatively were 351.84+/-243.85 microg/m2/day (mean+/-SD) and 17.92+/-7.86 mg/g creatinine/day, respectively. No correlation was found between these levels and the severity of the lesions. All patients were cured. Symptoms decreased dramatically within the 3 postoperative months and progressively disappeared within the first year of the follow-up period with the exception of light-colored striae; they were present in 5.6% of the patients at 18 months postoperatively. No acanthosis nigricans or hyperpigmentation were observed at 3 months postoperatively. Hirsutism was not present at 9 months postoperatively. We conclude that in children with CD the skin is affected at multiple sites; however, the severity of the manifestations does not correlate with the biochemical indices of the disease. With the exception of striae, cutaneous effects of endogenous hypercortisolism completely heal within the first year after surgical cure of the disease. | lld:pubmed |
