Various types of glomerulonephritis can occur at the same time with Hodgkin lymphoma, including minimal change disease and membranous glomerulonephritis. However, the concurrence of IgA nephropathy with Hodgkin lymphoma is rare. We report here on a case of IgA nephropathy in a patient with newly diagnosed Hodgkin lymphoma: A 60-year-old man presented with weight loss and anorexia. The patient showed lymphadenopathies in the neck on physical examination, and multiple lymphadenopathies in the mediastinum and abdomen on computerized tomography. Diagnosis of Hodgkin lymphoma was made after cervical lymph nodes were excised, but during the course of the chemotherapy, laboratory findings of hematuria and an elevated creatinine level were observed and IgA nephropathy was additionally diagnosed from a renal biopsy. There were fluctuations in the creatinine level and the amounts of hematuria and proteinuria, but by the time of the eighth cycle of chemotherapy, the patients condition had rapidly deteriorated, mainly due to the newly developed adult respiratory distress syndrome. The patient died soon thereafter.

Epidermoid cysts in the kidney have rarely been reported, and in most cases its pathogenesis has not been well understood. We report a case of an epidermoid cyst in a kidney with nephrolithiasis in a 61-year-old man. A pyelonephrolithotomy was performed on the patient four years ago to treat nephrolithiasis of the left kidney. During the follow-up, a newly developed mass was discovered three years ago and the mass has recently increased in size. A unilateral nephrectomy was performed under the clinical impression of renal cell carcinoma. Gross examination revealed a well encapsulated cystic mass measuring 3.0 x 2.0 x 2.0 cm and containing lumps of soft whitish material, in the upper pole of the left kidney. This location was the same as that of previous nephrolithiasis. Microscopic examination revealed typical findings of an epidermoid cyst. We suspect that the chronic irritation induced by renal stones may be associated with the development of the epidermoid cyst in this case.
