Abstract
Introduction
Calciphylaxis is a rare clinic condition characterised by skin necrosis due to medial and intimal calcification of small and medium arteries. It's observed in patients affected by end stage renal disease associated to secondary hyperparathiroidism. Penile involvement has been documented in very few cases. We present both a case of penile calciphylaxis and a review of literature, in order to increase comprehension of patophysiology diagnosis and therapy of this rare disease.
Materials and Methods
A retrospective review of literature was performed after treating a case of penile calciphylaxis. We describe patient characteristics, clinical presentation, laboratory and histopathologic findings, therapeutic strategy and outcomes of the case.
Results
A 65 year-old man, affected by diabetes, chronic ischemic cardiopathy and chronic renal failure in emodialithic treatment, was referred to our unit for the presence of increased consistency and significative pain of the distal portion of penis evolving in a complete glans necrosis. Blood levels of parathormone (PTH), calcium (Ca) and phosphorous (P) resulted pathologically elevated, promoting tissutal calcium deposition. The patient was treated with partial penectomy and the histologic findings confirm diagnosis of calciphylaxis, showing an ulcerative necrosis of glans with extensive calcium deposition and luminal narrowing of penile small arteries.
Conclusions
The increase of number of patients with chronic renal failure in emodialithic treatment could make penile calciphylaxis more p\revalent in the future. Early diagnosis, lowering of pathologic blood levels of Ca and P associated to surgical treatment of necrotic lesions of the patient could be fundamental for a better prognosis of this aggressive disease.
