[Riedel's thyroiditis: a report of a case with fatal outcome]. / Tiroiditis de Riedel: a propósito de un caso de evolución letal.

The Riedel's thyroiditis is a chronic inflammatory disease of the thyroid gland characterized by a process of fibrosis that destroys the gland partially, extending to the adjacent cervical structures. Its origin is unknown, although there are several theories in this respect. The clinical manifestations are not specific and it confuses frequently with neoplasia or infection, like a hard and painless thyroid mass that causes compressive symptoms. In this work, we report a case with lethal outcome.

[Inverted carcinoma of kidney pelvis coexisting with transitional cell carcinoma of the bladder. A therapeutic alternative]. / Carcinoma invertido de pelvis renal coexistente con carcinoma de células transicionales de vejiga. Una opción terapéutica.

OBJECTIVE: To describe a case of inverted carcinoma of the right renal pelvis associated with transitional cell carcinoma of the bladder. The unusual nature of this condition and the incidence of tumor recurrence in some patients with bladder cancer and, at least initially, no histopathological evidence of infiltrating tumor prompted us to report this case. METHODS/RESULTS: A 65-year-old male consulted for prostatism. Several months earlier he had had an episode of hematuria. The difficulty in making the diagnosis is underscored and the possibility of conservative surgical management is discussed. Tumor recurrence at two sites distinct from that of the bladder tumor warranted TUR. Two years after the first surgical procedure the patient is disease-free. CONCLUSION: Like most authors, we usually perform radical surgery in these cases. However, in the case described herein, the difficulty in making the diagnosis prompted us to use a conservative approach which, at the present time, appears to have been effective for the renal tumor. New treatment options, like endourological surgery, may have an important place in the management of this tumor type in carefully selected cases.

[Sertoli cell tumor of the testis. Report of a case]. / Tumor testicular de células de Sertoli. Aportación de un caso.

OBJECTIVE: To describe an additional case of Sertoli cell testicular tumor. Although more cases have been reported in the world literature, only one case with bilateral involvement has been described in the Spanish literature over the last 18 years. METHODS: A 34-year-old male consulted for a testicular mass which he had detected a few weeks earlier. US and CT evaluation disclosed a tumor in the right testis and no evidence of metastasis. The patient underwent right radical orchidectomy via the inguinal approach and insertion of a testicular prosthesis. RESULTS: Histopathological analysis of the surgical specimen disclosed a Sertoli cell testicular tumor. Patient control follow-up at 3 and 9 months postoperatively showed no changes in tumor markers or CT findings. CONCLUSION: The benign or malignant nature of Sertoli cell testicular tumor is currently defined by the presence or absence of metastasis, although there are histopathological criteria that might indicate a certain degree of aggressiveness.

[Eosinophilic cystitis associated with transitional cell carcinoma: apropos a case]. / Cistitis esosinófila asociada a carcinoma de células transicionales: a propósito de un caso.

An additional case of eosinophilic cystitis coexisting with transitional cell carcinoma of the bladder is presented. The patient was treated with antihistamine but posteriorly presented with an infiltrating tumor that warranted a cystectomy procedure and ureteroileostomy. The patient is currently symptom-free.

[Inverted papilloma of the ureter]. / Papiloma invertido de uréter.

We report a case of inverted urothelial papilloma localized to the ureter in a patient with solitary kidney. Treatment was by segmental resection and end-to-end anastomosis. In spite of the benign nature of this tumor type and because treatment is conservative, patients should be closely followed owing to the possibility of recurrence and because progression to malignancy has been reported in the literature.

[Urethral condylomata acuminata: management and review of the literature]. / Condiloma acuminado uretral: manejo y revisión de la literatura.

A case of condyloma acuminata occupying almost the entire penile urethra is reported herein. The literature is reviewed highlighting its etiopathogenesis, histologic features, and treatment according to the stage of the disease. The different treatment modalities that have been utilized and those currently used are described, with a special emphasis on the increasing importance of laser therapy. Some considerations are presented relative to diagnosis, and a therapeutic protocol according to the stage of the disease is described. Due to the high incidence of recurrence, close follow-up of these patients is advocated.

[Eosinophilic cystitis]. / Cistitis eosinófilica.

Eosinophilic cystitis is an uncommonly diagnosed disease entity whose etiology is unknown, although factors favoring its presentation such as disorders due to hypersensitivity and associated vesico-prostatic disease have been mentioned. Four cases are presented. The clinical features, complementary tests, treatment, and course are discussed and the literature reviewed.

[Inverted papilloma of the bladder]. / Papiloma invertido de vejiga.

We report a case of inverted papilloma in a patient submitted to TUR of a polypoid mass in the bladder neck, highlighting the coincident clinical features of the cases reported in the literature.
