Pseudotumoral calcinosis is a rare condition characterized by periarticular calcium deposition. It preferentially affects large joints such as the hip, shoulder and elbow. It is a severe complication of chronic renal failure. We report a case of secondary pseudotumoral calcinosis in a chronic hemodialysis patient.
Pubo-penile ectopic testis is a rare congenital anomaly whose etiopathogenesis is still poorly understood. We report one case of bilateral pubo-penile ectopic testis in a two-year-old child. The diagnosis was made on physical examination alone. Orchidopexy in the dartos muscle was easy to perform.
Renal cell carcinoma of the collecting ducts is one of the least frequent variants of renal carcinomas, with highly aggressive behavior, having the worst prognosis and the lowest specific cancer survival rate of all renal carcinomas, as 70% of patient deaths are secondary to the disease. We present a clinical case of a male patient with a diagnosis of paraneoplastic syndrome secondary to renal neoplasia. After a renal biopsy returned a diagnosis of sarcomatoid carcinoma, the patient elected surgical excision, and final pathology was consistent with renal carcinoma of the collecting ducts. As was common in the largest published series, this patient developed local and distant relapse in the early post-operative period, despite adjuvant systemic treatment. This variant of renal carcinoma has an ominous short-term prognosis, with high rates of distant disease present at the time of diagnosis. The unfavorable biological behavior manifests despite the use of multi-modality, adjuvant treatment.
