Scrotal tumors. / Tumores escrotales.

OBJECTIVE: Basal cell carcinoma and leiomyoma of the scrotum are rare. We describe three cases of scrotal tumors and provide information regarding this disease. METHODS: Between 2000 and 2014, 3 patients with scrotal tumors were diagnosed and treated at our institution. A review was performed using the clinical records of these patients. RESULTS: We describe two cases of basal cell carcinoma of the scrotum in men 72 and 71 year old, who presented with a left scrotal lesion that was excised and the pathological diagnosis was basal cell carcinoma. In one patient, surgical margin was affected and a recurrent basal cell carcinoma appeared. It was excised with enlargement of surgical margin. We also describe a case of scrotal leiomyoma in a 48 year old man with an elastic, firm and nontender lesion in the right scrotum. During follow-up the patients remain clinically asymptomatic. CONCLUSIONS: Scrotal lesions in the elderly should be excised and submitted for pathological examination. The basal cell carcinoma of the scrotum appears as a plaque, nodule or ulcer. Long-term surveillance is recommended for these patients. Leiomyoma of the scrotum is presented as a non-ulcerative nodule and his treatment is complete surgical excision.

Carcinoma de los ductos de Bellini. Aportación de dos nuevos casos / Bellini duct carcinoma: report of two cases

Objetivo: Presentamos dos casos de carcinoma de ductos de Bellini diagnosticados en nuestro servicio en un plazo de seis meses. Método/resultado: El caso nº1 es una mujer de 75 años de edad en la que un TAC, realizado por estudio de patología digestiva, mostró una masa en el riñón izquierdo que infiltraba grasa perirrenal. El caso nº2 es un varón de 72 años que al realizar estudio por TVP bilateral de miembros inferiores, se evidenció en el TAC una lesión renal derecha dependiente de la pelvis, mal definida, con afectación de la vena cava y renal derecha. Tras la realización de nefrectomía radical en ambos casos, se confirmó el diagnóstico anatomopatológico de carcinoma de ductos de Bellini. Conclusión: El carcinoma de los ductos de Bellini es una rara variedad de tumor renal que deriva de los ductos colectores de la médula renal. Caracterizado tanto por su agresividad, como por su peculiar diagnóstico, histológico e inmunohistoquímico, que lo diferencia del resto (AU)

Objective: We report two cases of collecting duct carcinoma that were diagnosed in our hospital in a six-month period. Methods/results: The first case was a 75-years-old woman showing in CT scan a mass in the left kidney which infiltrated perinephric fat. The second case was a 72-years-old that showed in a CT scan a right renal pelvis lesion, involving inferior vena cava and renal vein. After surgical resection by radical nephrectomy in both cases, we confirmed the histological diagnosis of collecting duct carcinoma. Conclusions: Collecting duct carcinoma is a rare variant of renal cell carcinoma which originates from the epithelium of the collecting tubule. It is characterized by both its aggressiveness and peculiar histological and inmunohistochemical diagnosis, that separates it from the rest of renal tumors (AU)

[Bladder endometriosis. Report of two cases and bibliographic review, with special focus on Spanish articles]. / Endometriosis vesical. Revisión de la literatura, con especial referencia a la española y aportacion de dos nuevos casos.

OBJECTIVES: To study and review the etiopathogenic hypothesis for endometriosis and the clinical features, diagnosis and treatment of bladder endometriosis. METHODS/RESULTS: We report two cases and review the international bibliography, collecting the cases published by Spanish authors. CONCLUSIONS: Bladder endometriosis is a rare pathological entity, but its diagnosis should be considered in fertile women with urinary tract symptoms during menstruation. Diagnosis is obtained by various imaging tests (ultrasound, CT scan, MRI), and is confirmed with cystoscopy and biopsy. The treatment may be surgical (TUR, partial cystectomy) and/or medical (hormonal).

Endometriosis vesical. Revisión de la literatura con especial referencia a la española y aportación de dos nuevos casos / Bladder endometriosis. Report of two cases and bibliographic review, with special focus on Spanish articles

OBJETIVO: Estudio y revisión de las hipótesisetiopatógenicas de la enfermedad endometriósica y de la clínica, diagnóstico y tratamiento de la endometriosisvesical.MÉTODOS/RESULTADOS: Se revisa la literatura internacional,se recogen los casos publicados por autores españoles y se aportan dos casos propios.CONCLUSIONES: La endometriosis vesical es una entidadpatológica poco frecuente, pero hay que pensar en su diagnóstico en mujeres en periodo fértil con síntomasurinarios coincidentes con la menstruación. Su diagnóstico se efectúa con diversos métodos de imagen (ecografía, TAC, RMN) y se confirma con cistoscopia y biopsia. El tratamiento es quirúrgico (RTU, cistectomía parcial) y médico (hormonal)

A fatal case of congenital disseminated Langerhans cell histiocytosis.

The case of a newborn male infant with congenital Langerhans cell histiocytosis (LCH) is presented. At birth, showed cutaneous lesions (papules and vesicles with a haemorrhagic aspect), mucosal and ganglionic involvement. Biopsy of these lesions led to the diagnosis of LCH. At 24 hours of life the patient began with respiratory, hepatic, hematological and renal dysfunction, and died at 72 hours of life, despite corticoid treatment. LHC with vesicles and a rapid and fatal development, has previously only been described in three patients. The differential diagnosis of a disseminated and hemorrhagic vesicular eruption in a newborn infant is extensive and must include LHC.

[Bilateral adrenal pheochromocytoma]. / Feocromocitoma suprarrenal bilateral.

Presentation of one case of bilateral suprarenal pheochromocytoma as early clinical evidence of a type 2 MEN, which at the time of diagnosis was a bilateral lesion. The presentation form was a picture of shock with HBP. Labetalol i.v. was used for initial control and phenoxybenzamine in the pre-operative. Diagnosis was achieved by biochemical (metanephrine) and radiological (CAT) testing. The patient was managed with bilateral suprarenalectomy through a single, anterior incision and abdominal cavity examination. The investigation of the remaining conditions that conform this syndrome was continued and a familial routine study implemented.

[An experimental study of the efficacy of politetrafluoroethylene grafts in tracheal surgery]. / Estudio experimental de la eficacia de injertos de politetrafluoroetileno en cirugía traqueal.

We studied the efficacy of polytetrafluoroethylene (PTFE) grafts in the surgical correction of extensive tracheal defects in rabbits. Results showed anastomotic stenosis in 100% of the animals after primary reconstruction when a total of six complete rings were resected. We did not appreciate tracheal stenosis in no animal when we applied a PTFE prosthesis placed around the anastomotic site. Results were not satisfactory upon repairing partial tracheal defect by means of a spindle of PTFE prosthesis. We concluded that the external tutor is useful for the surgical correction of the tracheal stenosis induced after resection of six rings in the cervical tracheal of the animal.
