The third case of a malignant non-Hodgkin lymphoma of the female urethra is reported. The urethra was the primary localisation of the malignancy. In the two other cases which could be found in a literature review urethral involvement by this disease was secondary to other organs. In all cases the tumor first was described as a caruncle. Non-Hodgkin lymphoma should be considered in the differential diagnosis of urethral tumors.

We report the first case (to our knowledge) of a primary urethral T-cell lymphoma as the initial manifestation of the acquired immune deficiency syndrome. A 36-year-old white homosexual man with antibodies to human immunodeficiency virus type 1 was evaluated for a hemorrhagic urethral discharge. A 2-cm fleshy, polypoid mass in the bulbous urethra was removed, and the diagnosis of small non-cleaved cell (non-Burkitt's) lymphoma was made. Immunohistochemical analysis confirmed that the tumor was of T-cell lineage. Patients with the acquired immunodeficiency syndrome have an increased incidence of lymphomas, particularly extranodal high-grade non-Hodgkin's lymphomas. Primary urethral lymphomas are extremely rare, with only a handful of cases reported in the literature. This rare form and site of lymphoma should be considered in patients with the acquired immunodeficiency syndrome who have genitourinary symptoms.

A case of retroperitoneal Hodgkin's disease with dysuria is reported. A 56-year-old man visited our hospital with the complaints of dysuria and lower abdominal mass. On physical examination, an unmovable hard smooth mass of fist size was palpable in the lower abdomen and prostate was slightly swelling by rectal digital examination. Excretory urography demonstrated medial deviation of left lower ureter and bladder deformity. Retrograde urethrocystography showed deviation and compression of prostatic urethra. On CT, tumors were composed of several round masses, which surrounded the left common iliac artery on angiography. Surgical extirpation was carried out and histological examination revealed Hodgkin's disease. As postoperative treatment, chemotherapy with cyclophosphamide, adriamycin, vincristine and prednisolone was performed, and 30 months after the operation the patient was asymptomatic.

Thirty-five patients, 38 to 88 years of age, were treated with 125-Iodine or 192-Iridium interstitial implants at Stanford University Medical Center between July 1974, and December, 1978. There were 25 primary epithelial malignancies, eight extensions from intrapelvic organs and two metastatic tumors (hypernephroma and Hodgkin's disease). The involved sites were: urethra (6 patients); vulva (9 patients); vagina (8 patients); anus (7 patients); cervix (5 patients). Implantation was usually performed to treat evident or microscopic disease in conjunction with external beam pelvic treatment with or without local excision. Computerized implant preplanning was used. 125-Iodine seeds were inserted either directly or within absorbable suture Polyglactin 910; 192-Iridium in nylon carriers was placed by suture or transperineal template. Two patients were lost to follow-up leaving 33 patients, 27 of whom are alive and free of local disease from 37 to 76 months. The overall local control rate was 88%, or 29/33 patients. All four local recurrences appeared before 24 months. Minor complications included: 10 patients with transient mucositis, four with superficial ulcers, and one patient with infection at the implanted site. Two major complications occurred: a necrotic rectal ulcer requiring a colostomy and a contracted, painful bladder necessitating a urinary diversion. We conclude that in selected cases interstitial irradiation provides good local control of perineal and gynecological malignancies with low morbidity in this elderly and quite often fragile group of patients.

Only about 2% of the urinary tract are not of urothelial origin. Our knowledge of their morphology and biology is mainly based on single case reports, and therefore apart from a few exceptions very poor. Generally, the most often affected site is the urinary bladder (79.2%), followed by the urethra (12.7%), pelvis (4.9%) and ureter (3.2%). The urinary bladder also is the only organ in which all different histological types of these tumors were described. According to their histogenesis non-urothelial tumors (NUT) can be classified by the following main groups: soft tissue tumors, mixed epithelial and non epithelial tumors (carcinosarcomas), neuroendocrine carcinomas, carcinoids, malignant lymphomas, malignant melanomas and extragonadal germ cell tumors. Moreover some very interesting tumor-like lesions, like malakoplakia and inflammatory pseudosarcoma, mainly occur in this region. About 75% of all NUT of the urinary tract belong to the soft tissue tumors. Rhabdomyosarcomas in children and leiomyomas and -myosarcomas in adults are the more frequent histological types. Leiomyosarcomas can easily be confused with other tumor types or even with inflammatory pseudotumors. The use of immunohistochemistry to achieve a correct diagnosis is mandatory but not always successful. A relatively frequent tumor occurring in the bladder of young adults is the paraganglioma (pheochromocytoma), which usually produces typical symptoms of catecholamine excess. Carcinosarcomas of the urinary bladder contain both epithelial and mesenchymal components. They have to be distinguished from collision tumors (coexistent but separate carcinoma and sarcoma), spindle cell transitional carcinomas as well as from carcinomas with osseous or cartilaginous metaplasia. Carcinoids and neuroendocrine carcinomas developed from the neuroendocrine cells scattered all over the transitional epithelium of the bladder. Neuroendocrine carcinomas of the bladder are also called "oat cell carcinomas" since they show the same histological features and immunoreactivity as the oat cell carcinomas of the lung. They share also the same poor prognosis. The affection of the urinary tract in generalized malignant lymphomas and leukemias occur in more than 30% of cases. Lymphomas, primarily localised in the urinary bladder are, however, extremely rare. The most frequent ones are low grade non Hodgkin lymphomas, although 3 cases of Hodgkin disease and a few cases of primary extramedullary plasmacytoma of the bladder have been reported, too.(ABSTRACT TRUNCATED AT 400 WORDS)

Primary malignant lymphomas in the female urethra are extremely rare. We report a 63-year-old woman who presented with a localized tumor of the urethral meatus. The tumor was classified as a non-Hodgkin's malignant lymphoma, a diffuse, small cleaved cell type according to the Working Formulation classification. Immunohistochemistry confirmed that the tumor was derived from B cells. The patient underwent chemotherapy and remains free from evidence of the disease 3 yr after excision. To our knowledge she is the seventh case of malignant lymphoma in the female urethra reported in the English literature.

We report a primary non-Hodgkin's B-cell lymphoma of the urethra in a 78-year-old female. Serum antibodies for Epstein-Barr virus (EBV) were negative, but there was a 40-fold increase in antibodies to EBV-associated nuclear antigen. Using PCR and in situ hybridization techniques, EBV genome was found in the tumour cell nuclei.

Approximately 15-25% of malignant non-Hodgkin's lymphomas (NHLs) are primarily extranodal and only 2.7% of these are located in the genitourinary tract. Only a few particular cases of primary manifestation of NHL in the urethra have been described, most of them in female patients, whereas a secondary involvement occurs more frequently. In the present case a high-grade malignant NHL of the B-cell type was located in the urethra of a 29-year-old male patient. No other manifestations of NHL could be found. After surgical removal of the urethral neoplasm the patient was treated with combined chemotherapy (6 cycles of the CHOP scheme). Thereafter, reconstruction of the urethra by the island flap method of Duckett was carried out. Two years after diagnosis the patient is alive and in complete remission with good functional and cosmetic results of surgery and a normal sexual life.

Primary non-Hodgkin's lymphomas rarely arise from the lower urinary tract, the urethra being the most uncommon site of origin. Herein, we report the immunohistochemical findings of a case of primary marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) arising from the male urethra. To clarify the clinicopathological findings of primary urethral lymphoma, we reviewed 14 previously reported cases. A 56-year-old man presented with gross hematuria. Cystourethroscopy demonstrated a nodular bulge of the urethral wall. Histologically, a transurethral biopsy specimen showed a dense lymphoplasmacytoid infiltrate in the urethral mucosa. The tumor cells were composed of centrocyte-like cells, plasma cells and plasmacytoid cells. A few plasma cells contained intracytoplasmic pseudoinclusions (Dutcher bodies). Immunohistochemical study revealed monotypic intracytoplasmic kappa-light chain in the plasma cells and plasmacytoid cells. The patient received a total of 50 Gy extrabeam irradiation. Follow-up 21 months later did not disclose any sign of local or other recurrences.

Diffuse large B cell lymphoma (DLBCL), currently the most common type of non-Hodgkin lymphoma (NHL), is an aggressive B cell neoplasm that typically presents in older adults as a rapidly enlarging mass. The enlarging mass typically represents a lymph node, although extranodal disease can occur in a significant percentage (40%) of cases. The most common extranodal sites of involvement include the gastrointestinal tract and skin; primary bladder lymphoma represents only 0.2% of extranodal non-Hodgkin lymphomas. We report a case of diffuse large B cell lymphoma occurring in the bladder of an 83-year-old gentleman with an initial presentation of hematuria. This neoplasm displayed large, atypical cells with vesicular chromatin and prominent nucleoli that involved the bladder mucosa with invasion into muscularis propria, prostate, and urethra. Positive staining for p63 initially raised suspicion for poorly differentiated urothelial carcinoma; however, lack of staining for pancytokeratin and positive staining for LCA, CD20, CD79a, and PAX-5 confirmed the diagnosis of diffuse large B cell lymphoma. Though it does not occur in all cases, p63 can be positive in a significant percentage of cases of DLBCL; therefore, a diagnosis of lymphoma remains an important entity on the differential diagnosis of aggressive and particularly poorly differentiated neoplasms.
