RESUMO
A 66-year-old male was referred to our hospital for further examination of a scrotal mass. Because of the risk of testicular cancer, we first clamped the vessels as a course of higher orchiectomy. Then, we approached the tumor through the scrotum and successfully resected it while preserving the testis. A histopathological diagnosis revealed an epidermal cyst. We herein report a rare case of an intrascrotal epidermal cyst successfully treated while preserving the testis.
RESUMO
There are various forms of renal lesions in patients with human immunodeficiency virus(HIV), however reported cases of immune-complex glomerulonephritis are scarce. Here we describe an HIV-positive patient with Henoch-Schönlein purpura nephritis(HSPN), which presented as nephrotic syndrome. In addition to therapy combined with glucocorticosteroid and inhibition of the renin-angiotesin system(RAS), plasmapheresis and antiretroviral therapy produced a favorable outcome. A 26-year-old HIV positive man was admitted for purpura on both lower limbs. Despite glucocorticosteroid treatment, purpura recurred and urinary protein increased to 5-10 g daily. HSPN was diagnosed based on the skin and renal biopsies. During 2 months of treatment with combined glucocorticosteroid and RAS inhibition, nephrotic syndrome persisted. He received double filtration plasmapheresis(DFPP). Soon after, urine protein decreased to 2-3 g daily and macrohematuria decreased. The second renal biopsy showed a decrease in IgA deposition and improvement of acute inflammatory changes. In addition, highly active antiretroviral therapy was started to reduce the high viral load. After 3 weeks, HIV-1-RNA rapidly decreased and urine protein decreased to 1 g daily. After a year, urinary protein was negative, but mild microhematuria persisted. We speculate that the refractory nephrotic syndrome in this patient might be associated with the abnormal immunological condition due to HIV infection.
