ABSTRACT
Resumen El tumor desmoplásico de célula redonda y pequeña (TDCRP) es una patología neoplásica maligna agresiva y poco común. Afecta predominantemente a hombres entre la segunda y tercera década de la vida. Los pacientes que la padecen tienen un pronóstico pobre, con una supervivencia global a 5 años de hasta el 30%. Por lo general se presenta como una masa en la cavidad abdominal, frecuentemente multifocal. Para su tratamiento se recomienda un enfoque multimodal con cirugía, quimioterapia y radioterapia. Poco más de 20 casos de TDCRP a nivel testicular/paratesticular se han reportado en la literatura. A continuación, se presenta un caso ilustrativo en esta localización, se discute el caso y se realiza revisión de la literatura.
Abstract Desmoplastic small round cell tumor (DSRCT) is an aggressive and rare malignant neoplasm. It mainly affects young men in their twenties and thirties. Patients with it have a poor prognosis, with a 5-year survival rate of up to 30%. It generally presents as a mass in the abdominal cavity, often multifocal. A multimodal approach is recommended for its treatment, with surgery, chemotherapy, and radiotherapy. Just over 20 cases of testicular/paratesticular DSRCT have been reported in the literature. Below, we present an illustrative case in this location, we discuss the case and review the literature.

Paget's disease, described by Sir James Paget in 1874, is classified as mammary and extramammary. The mammary type is rare and often associated with intraductal cancer (93-100% of cases). It is more prevalent in postmenopausal women and it appears as an eczematoid, erythematous, moist or crusted lesion, with or without fine scaling, infiltration and inversion of the nipple. It must be distinguished from erosive adenomatosis of the nipple, cutaneous extension of breast carcinoma, psoriasis, atopic dermatitis, contact dermatitis, chronic eczema, lactiferous ducts ectasia, Bowen's disease, basal cell carcinoma, melanoma and intraductal papilloma. Diagnosis is histological and prognosis and treatment depend on the type of underlying breast cancer. Extramammary Paget's disease is considered an adenocarcinoma originating from the skin or skin appendages in areas with apocrine glands. The primary location is the vulvar area, followed by the perianal region, scrotum, penis and axillae. It starts as an erythematous plaque of indolent growth, with well-defined edges, fine scaling, excoriations, exulcerations and lichenification. In most cases it is not associated with cancer, although there are publications linking it to tumors of the vulva, vagina, cervix and corpus uteri, bladder, ovary, gallbladder, liver, breast, colon and rectum. Differential diagnoses are candidiasis, psoriasis and chronic lichen simplex. Histopathology confirms the diagnosis. Before treatment begins, associated malignancies should be investigated. Surgical excision and micrographic surgery are the best treatment options, although recurrences are frequent.

Genitourinary tumors may show varied clinical presentation and frequency in different regions of the world. The present study was therefore conducted to analyze the frequency, clinical presentation and the histopathological types of the various male genitourinary tumors diagnosed over a period of 14 years in a major teaching institute of north Himalayan region of India. Material and Methods: Retrospective study was undertaken in the Pathology department of the Institute which included all the cases of male genitourinary tumors which were diagnosed on histopathology from the time period between 1 Jan 1997 till 31st Dec. 2010. Results: The study showed that prostate was the most common site for male genitourinary tumors with prostatic adenocarcinoma as the most common histopathological type of tumor. Testicular Non- Hodgkin’s lymphoma constituted about 8% of total tumors in testes which mostly presented in elderly age group. Renal cell carcinoma (66.2%) was the most common tumor in kidney with much lower frequency of Wilm’s tumor (16.9%). Occasional rare tumors such as hemangioma of urinary bladder and schwannoma of penis were also seen over 14 years. Conclusion: The study concludes clinically patients were associated with more severe symptoms as they presented late to the hospital from the remote areas of this Himalayan region leading to late detection of tumors. Prostatic adenocarcinoma was the most common tumor while renal cell carcinoma was most common tumor in kidney. The present study provides valuable information to clinicians and pathologists regarding frequency, clinical presentation and histopathological types of male genitourinary tumors in this region which can be further used to formulate strategies for better management of these tumors.

El carcinoma de Verrucous en el área anogenital ha sido reportado bajo una variedad de nombres, incluyendo el condiloma acuminado gigante o tumor de Buschke-Loewenstein. Histológicamente, corresponde a un carcinoma espinocelular bien diferenciado. Se ha descrito una variedad de alternativas terapéuticas, siendo de primera elección la extirpación quirúrgica. El Imiquimod en crema al 5 por ciento representa un modificador tópico de la respuesta inmune. Actualmente está siendo utilizado en el tratamiento de una variedad de enfermedades cutáneas. Objetivo: Revisión del tema y presentación del primer caso de carcinoma verrucous anogenital tratado con cirugía shaving más criocirugía e imiquimod al 5 por ciento en crema con un seguimiento de siete años. Caso clínico: Paciente de sexo masculino, de 55 años, heterosexual, con antecedentes de lesión tumoral inguino-escroto-perineal derecha de 15 años de evolución y de crecimiento lentamente progresivo. Su primera consulta dermatológica se efectúa el 04.02.99. Se extirpa nódulo de tamaño mayor tamaño para examen histopatológico tipificación VPH por PCR (positivo para genotipos 6 y 11) Se diagnostica carcinoma espinocelular de bajo grado de malignidad. Se utilizaron en su tratamiento múltiples técnicas combinadas con métodos citodestructivos e inmunoterapia. Posteriormente se iniciaron ciclos de imiquimod 5 por ciento (una aplicación nocturna tres veces por semana) por seis semanas y luego ciclos de cuatro semanas cada uno, dos-tres veces al año. Se hizo un seguimiento a siete años, logrando erradicar exitosamente la enfermedad clínica y controlando las recidivas de forma satisfactoria.
Verrucous carcinoma of the anogenetal region has been reported under a series of names, including giant condyloma acuminatum or Buschke-Loewenstein tumor. Histologically, it corresponds to a well differentiated squamous carcinoma. A number of therapeutic alternatives have been described, the first choice being surgical removal. Imiquimod cream 5 percent represents a topical modifier of the immune response, and is currently being used in the treatment of a series of skin diseases. Objective: We present a review of the literature and the first case of anogenital verrucous carcinoma treated with a seven-year follow-up. Clinical case: A55-year-old man, with a history of a giant condyloma acuminatum with histological evidence of a low degree multiple techniques combined with cytodestructive methods and immunotherapy. A seven-year follow-up was carried out, success-fully eradicating the clinical disease and controlling recurrence with cycles of imiquimod cream 5 percent treatment (average 3 monthly treatment cycles per year).

Os tumores de testiculo representam uma forma rara de neoplasia no sexo masculino. No periodo de 12 anos, foram atendidos 234 individuos portadores de tumor germinativo do testiculo, e destes, 173 foram seguidos no periodo pos-operatorio. Do total analisado, 137 eram seminomas que responderam satisfatoriamente ao tratamento e com sobrevida de 96 por cento em 3 anos, e 38 tumores nao-seminomatosos, cuja taxa de sobrevida foi de 84 por cento , no mesmo periodo. Dois pacientes apresentaram tumores em ambos os testiculos, de forma assincronica. O acompanhamento pos-operatorio medio foi de 36 meses

Se analizaron 50 parejas que presentaban evidencia citológica y o clínica por Papiloma virus en el tracto genital. Las edades de las mujeres fluctuaron entre 18 y 52 años y la de los hombres entre 25 y 58 años. Se realizaron estudios de rutina, histológicos en las mujeres y citológicos en los hombres. Se trataron los casos con criocirugía, efudix o tratamiento mixto. Se destaca la importancia de la colposcopia ya que un porcentaje no despreciable (38%), no da información citológica. La asociación de HPV-NIE es frecuente (44%)
