RESUMO
Primary malignant lymphoma of the testis is an uncommon tumor, accounting for only 1 to 9% of all testicular neoplasms and 1% of all non-Hodgkin's lymphoma. Especially, T cell lymphoma of the testis is very rare. However, it is the most common testicular malignancy in the elderly. It has a propensity for extranodal spread to the skin, subcutaneous tissue, CNS and lung. Immunohistochemical studies of testicular lymphoma have showed that the majority of these are B cell lymphomas, with rare reports of T cell lymphomas. Given the rarity of this disease, treatment has not been standardized. However, there is universal agreement that orchiectomy is the initial treatment. Although excellent results with a doxorubicin-containing chemotherapy regimen have been achieved in early stage disease, most patients have relapse of disease and a grave prognosis. We experienced the primary T cell lymphoma of the testis that was developed in 41 year-old-man.

Angiomyolipoma is a rare benign tumor and approximately 20 to 50% of patients with the diagnosis of angiomyolipoma have some or all of the other stigma of tuberous sclerosis. Patients with tuberous sclerosis tend to be younger, more likely to have multifocal and bilateral disease. Angiomyolipoma which is not associated with tuberous sclerosis mostly affects middle aged women. According to literature data, angiomyolipoma is very rare in child and almost exclusively associated with tuberous sclerosis. We report a case of 14 year-old girl who has a renal angiomyolipoma without clinical evidence of tuberous sclerosis.

Objectives: The purpose of study is to evaluate serial MR imaging of myocardial infarction using non-surgical model of myocardial infarction after percutaneous transcatheter coronary arterial embolization in dogs. MATERIALS AND METHODS: We evaluated serial pre- and post-contrast MR images with Gd-DTPA (gadolinium-diethylenetriamine-pentaacetic acid) of heart of the eleven mongrel dogs (immediate group (n=3), one week group (n=3), three weeks group (n=5)) after making non-surgically induced myocardial infarction. We confirmed the infarct with TTC staining and microscopically. The location and extents of the myocardial infarction were correlated. RESULTS: A total of 24 MR images were archived; 11 images of the immediate post-embolic period, 8 images of one-week follow-up, and five of 3-week follow-up images. Comparing with the signal intensity of normal myocardium, immediate post-embolic MR images showed low or iso signal intensities (SI) of the infarct area on T1-weighted images (T1WI) and high SI on T2-weighted images (T2WI). No contrast enhancement with Gd-DTPA was made in all cases of the immediate post-embolic MRI. One-week and 3-week follow-up MR images showed low or iso SI on T1WI and slight high or iso SI on T2WI. Contrast enhancement images in both one-week and 3-week follow-up MRI showed denser enhancement of infarct area in one-week follow-up. The myocardial wall thinning was seen in 5 of eight dogs after one week and in 3 of five after 3 weeks. CONCLUSION: In non-surgical animal models of myocardial infarction, MR images showed low or iso SI on T1WI, and high SI on T2WI in various stages, and contrast enhancement was maximum after one week and gradual decrease to 3 weeks. The myocardial wall thinning was seen in one-to 3-week follow-up MR images.

Amyloidosis is characterized by deposition of homogenous, eosinophilic, hyaline material in various tissues. Presently, most cases occur in a generalized form as a manifestation of an underlying plasma cell neoplasm(myeloma) or plasmacytic dyscrasia. On the other hand, most cases of symptomatic amyloid disease in the urinary bladder has occurred as an apparently solitary, localized tumefactive process and mimicks invasive bladder tumor. We report a case of primary amyloidosis of the bladder which was diagnosed after transurethral resection in a 65-year-old man with chronic renal failure.

PURPOSE: Penile paraffinoma provokes many serious undesirable effects. We studied our series retrospectively to evaluate the outcome of surgical treatment according to the degree of penile skin defect after excision of the lesion. PATIENTS AND METHODS: Surgical treatment for penile paraffinoma was performed in 42 patients over 6 years. The operative methods were complete excision with primary closure (N=34) or bilateral pedicle scrotal flap (N=8). RESULT: The complications of bilateral pedicle scrotal flap were wound infection in 1 case and skin defect in 1 case. There were no complications of primary closure. CONCLUSIONS: We propose that the proper treatment of penile paraffinoma is complete excision with primary closure for a small denuded penis and bilateral pedicle scrotal flap for a large denuded penis.
