Fibrous pseudotumor of the testicular tunics is uncommon lesion. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Two-thirds involve the tunica vaginalis testis, with infrequent involvement of other scrotal structures. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, band-like myofibroblastic proliferations that encase the testis. We report here on a case of fibrous pseudotumor of the tunica vaginalis in 76 year-old patient. (Korean J Urol 2006;47:1130-1132)

An inflammatory myofibroblastic tumor (IMT) is relatively rare quasineoplastic lesion. An IMT usually presents as a single mass within a single organ or sometimes as multifocal lesions within a single anatomic region. An IMT involving noncontiguous multi-organs within different anatomic regions is extremely rare. We present a case of an aggressive IMT that involved the musculoskeletal system and multiple abdominal visceral organs.

The role of ultrasound (US) is limited in the pathologic diagnosis of soft tissue tumors. It is possible to predict the pathologic results of some common soft tissue tumors with typical US features. We report the US and pathologic findings of three angiolipomas, one nodular hidradenoma, and one benign myofibroblastic tumor, which are uncommon soft tissue tumors with characteristic US findings.

We herein report a case of palmar fibromatosis, who was 78-year-old male and had had multiple variable-sized subcutaneous hard nodules on the left palm for 2 months. Histopathologic findings of the lesion revealed that the nodules were highly cellular, containing numerous spindle shaped cells. Ultrastructurally, intracytoplasmic micrcfilaments were present, and the nuclei were extremely indented by one or more transverse folds. These findings suggested the cells were myofibroblasts.

Nodular fasciitis is a benign myofibroblastic proliferative lesion of the soft tissue. It appears typically as a rapidly growing painless solitary mass over several weeks' duration. It may be confused with a malignant tumor, especially with a sarcomatous lesion due to its aggressive clinical behavior and histological features. Only 7-20% of theses tumors are located in the head and neck since the retroauricular lesion is extremely rare. We report on a patient with nodular fasciitis as a retroauricular mass with a review of literature.

Infantile myofibromatosis is a rare neoplasm which occurs primarily in early infancy and arise in the various sites. A 4-year-old boy, who presented with painless soft scalp mass in the left temporoparietal region was diagnosed to have myofibromatosis and this case is presented with some literature reviews.
