[Cutaneous collagenous vasculopathy: a case report and review of the literature]. / Vasculopatía colágena cutánea: aportación de un caso y revisión de la literatura.

Cutaneous collagenous vasculopathy is an idiopathic microangiopathy first described in 2000 by Salama and Rosenthal.It must not be confused with generalized essential telangiectasia. To date, all patients have been white men over the age of 50 years, most of whom had multiple pathologies, were taking multiple drugs, and had no family history of similar conditions or hemorrhagic disorders. The disease is characterized by the development of various numbers of telangiectases on the limbs, lower abdomen, chest, or back, with no involvement of the mucosas or nail bed. Histopathology shows dilated superficial cutaneous vessels with perivascular deposits of periodic acid-Schiff diastase-positive, eosinophilic hyaline material that exhibits positive immunoreactivity to collagen IV. We report a new case in a 68-year-old man with symmetrically distributed telangiectases on his forearms, lower abdomen, posterior thighs, lower legs, and dorsum of the feet.

[Cutaneous ciliated cyst of the scrotal skin. A case report with discussion of pathogenesis]. / Quiste cutáneo ciliado en piel escrotal. Descripción de un caso con discusión patogénica de la entidad.

Cutaneous ciliated cyst (CCC) is a rare benign lesion predominantly occurring in the lower limbs of young women and exceedingly rare in males. Here, we report a case involving a previously unreported site (i.e., scrotal skin) in a 15-year-old male. We also describe pathologic and immunonohistochemical findings, review the pertinent literature and discuss their pathogenetic mechanisms. We propose that CCC could represent a morphologic pattern encompassing several pathogenetically different entities. Data we provide support the hypothesis that at least a part of CCC, specially those occurring in males, could have their origin in ciliated metaplasia of apocrine sweat glands.

[Granular cell tumour of prostate diagnosed by transrectal biopsy. Which therapeutic attitude?]. / Tumor de células granulares de próstata diagnosticado en biopsia transrectal. Qué actitud tomar?

Granular cell tumour (GCT) is not an uncommon tumour of neural origin usually located on subcutaneous tissues and oral cavity. In prostate gland is exceptional, with only one case reported on the indexed literature of the last three decades. We report a case of a 63-year-old man presented with urinary complaints, enlarged prostate and increased PSA levels. The patient subsequently underwent transrectal needle biopsy which revealed GCT. The clinicpathological dilemma originated after this diagnosis is discused and the most suitable follow-up is proposed.

[Nephrogenic adenoma of the bladder: metaplasia or embryologic alteration?]. / Adenoma nefrogénico vesical: metaplasia o alteración embriológica?

OBJECTIVES: To present a new case of nephrogenic adenoma of the bladder and to review the current concepts on the etiopathogenesis of this lesion. CLINICAL CASE: Seventy years old female with repetitive haematuria who was diagnosed as having a nephrogenic adenoma of the bladder which was extirpated by cold biopsy forceps. No tumoral relapse was detected after 16 months of follow up. DISCUSSION: In the light of the present knowledges, the origin of nephrogenic adenoma is a phenomenon of urothelial metaplasia due to a chronic irritative stimulus wich would lead a cellular proliferation with potentialities to originate mesonephric tissues and which starting point could be on not completely involutioned mesonephric cellular rests and/or on de-differentiated mature urothelial cells.

[Inflammatory pseudomotor of the bladder. A diagnostic and therapeutic dilemma]. / Pseudotumore infiammatorio vescicale. Un dilemma diagnostico e terapeutico.

Inflammatory pseudotumor is a reactive benign lesion which can be very difficult to distinguish from some malignant bladder tumors like sarcomas or sarcomatoid carcinoma. The aim of this study was to present a new case of inflammatory pseudotumor and to review the present diagnostic and therapeutic criteria for this lesion. A 72-year-old female was admitted to the emergency room due to important hematuria. Transurethral resection of a bladder tumor located in the left lateral wall was performed. Pathologic studies were suggestive of inflammatory pseudotumor, but a mixoid leiomyosarcoma couldn t be completely discarded and a partial cystectomy with ipsilateral lymphadenectomy were carried out. Immunohistochemical studies were positive for vimentin, desmin, smooth muscle actin and cytoqueratins while epithelial membrane antigen and S-100 protein were negative. The patient is disease free after a year follow-up. When diagnosis is certain, complete transurethral resection is the treatment of choice. However, if there is no total pathologic confirmation, if it is a very wide lesion or if it is recurring after endoscopic resection, a partial cystectomy is suggested.

Unusual retrovesical masses in men.

Retrovesical masses in men not related to prostatic carcinoma or hyperplasia is an uncommon pathology. Rare masses or unusual manifestations of those common diseases are a diagnostic dilemma. We review our experience in three unusual retrovesical masses in men: carcinosarcoma filling a giant bladder diverticulum; cystic prostatic carcinoma; and acquired cystic dilatation of the seminal vesicle associated with a prostatic carcinoma that obstructed and invaded the vesicle. We report the imaging findings and review the literature. In our experience, the imaging findings are usually not specific for doing a precise diagnosis and biopsy procedures are necessary.

Carcinosarcoma in a bladder diverticulum. A case report and literature review.

Carcinosarcoma of the bladder is a rare neoplasm composed of a mixture of malignant epithelial and mesenchymal components. The presentation and clinical course of an infiltrating carcinosarcoma located in a bladder diverticulum coexisting with prostatic adenocarcinoma in a 69-year-old man are described. We believe this to be the fifth report of true carcinosarcoma appearing in a bladder diverticulum.

Laparoscopic assessment and orchidectomy for the adult undescended testis.

The aim of this study was assessment of the usefulness of laparoscopy in the diagnosis and treatment of the adult nonpalpable testicle. We reviewed retrospectively the case notes of five adult patients with cases of impalpable testis that were evaluated and treated laparoscopically in our institutions. All five patients had unilateral nonpalpable testicles. The mean age of the patients was 36.5 years (+/- 5 years). Laparoscopy defined the intraabdominal anatomy accurately in all cases, and there were no laparoscopic complications. Two testes were found intra-abdominally, another testicle was found lying in the inguinal canal, and the last two testes were absent. Laparoscopy is a safe and reliable method in diagnosing adults with nonpalpable testis and also allows the completion of the operative procedure during a 1-day hospital stay.
