“…Complications caused by undescended testicles include a higher incidence of sertoliomas and seminomas. Statistically there is also a higher incidence of testicular tumors in animals less than 10 years-old when cryptorchidism is present (LIAO et al, 2009), which is corroborated by the findings in this dog. The development of tumors in abdominal or inguinal testicles might be related to the higher temperatures in those areas (ROMAGNOLI; SCHLAFER, 2006).…”

A male miniature Schnauzer with cryptorchidism and a mass growth in the right inguinal canal was admitted to the clinical center of a veterinary hospital. During surgical resection of the mass, tubular formations were found, connecting the mass to the left testicle. Histopathology revealed that the tubular formations were uterine tubes and the mass was a seminoma associated with a sertolioma of the right testicle. Further analysis also showed atrophy of the left testicle. Cytogenetic evaluation revealed normal chromosomes of male gender, 78, XY, which led to the conclusion that this was a male pseudohermaphrodite.

“…Testicular neoplasms are common in elderly dogs, less common in horses, and rare in other species (FOSTER, 2013). The most common testicular neoplasms in dogs are Leydig cell tumors, seminomas, and Sertoli cell tumors (LIAO et al, 2009). Metastases are rare, although sertoliomas can occasionally spread to inguinal lymph nodes.…”

“…Incidence of cryptorchidism is relatively high in dogs and it is well documented that cryptorchidism and advanced age are major risk factors associated with testicular tumours in dogs [12,16,19]. In addition to the present case, where the tumour was diagnosed at nine months of age (the mass was initially palpated per rectum at six months of age), tumours in other newborn and young cattle have been reported [2,6,17].…”

ABSTRACT. A six-month-old Japanese Black bull was found to have no left testis in the scrotum. A fist-sized mass was palpated per rectum. Two months later, hCG was injected and blood samples were collected before and after injection. No testosterone response to hCG was observed. On the cut surface of the excised mass, most of the mass was composed of homogeneous adipose-like tissue. The rest of the surface was composed of a well-circumscribed testicular parenchyma-like tissue (18  16  15 mm). Histology revealed diffusely distributed mature adipocytes and septa of fibrous connective tissue. Neither germ cells nor spermatozoa were observed in the seminiferous tubules. A diagnosis was made of fibrolipoma and aspermatogenesis of the left cryptorchid testis.KEY WORDS: cattle, cryptorchidism, fibrolipoma, testosterone concentrations.J. Vet. Med. Sci. 73(9): 1253-1255, 2011 Cryptorchidism is rare in cattle in comparison with other domestic animal species such as horses, dogs and pigs [1,20], and testicular neoplasia in cattle has been seldom described [6]. This short communication describes a case of bovine testicular fibrolipoma in a young bull with unilateral cryptorchidism.A six-month-old Japanese Black bull, from which a normal right testis had been removed, was found to have no left testis in the scrotum. On rectal examination, a mass of approximately 10  10  8 cm was palpated to the left of the bladder. No other clinical signs were observed and the animal had a normal appetite.When the bull was eight months old, plasma testosterone concentrations were measured. Human chorionic gonadotrophin (hCG; 3000 IU) was injected intramuscularly. Peripheral blood samples were collected five minutes before (D0), three days after (D3) and five days after (D5) injection. Plasma testosterone concentrations, determined by chemiluminescence immunoassay (Architect analyser i2000, Abbott Japan Co., Ltd., Tokyo, Japan), were 422, 468 and 363 pg/ml on D0, D3 and D5, respectively.At nine months old, the bull was hospitalised. Transrectal ultrasonography of the mass was performed using Bmode equipment (LogiqBook XP, General Electric Company, Fairfield, CT, U.S.A.) and a linear 8.0 MHz transd u c e r ( T 7 3 9 -R S , G e n e r a l E l e c t r i c C o m p a n y ) . Ultrasonography depicted a structure with a loss of homogenous echogenicity consistent with testicular parenchyma, and loss of the hyperechoic line of the mediastinum testis and with multiple hyperechoic areas. On rectal palpation, no abnormalities were detected in the internal accessory sex glands and other organs in the abdominal cavities.Laparotomy was performed through a left paramedian incision to excise the mass. The mass (10.5 × 9.5 × 7.0 cm, 415 g) had an elastic texture and was enclosed by a smooth, glistening, vascular capsule (Fig 1a). On the cut surface, most of the interior of the mass was milky-white and composed of homogeneous adipose-like tissue. The rest of the surface was composed of a well-circumscribed testicular parenchyma-like tissue, measuring 18 × 16...

“…A pesar de no existir suficientes datos sobre la ocurrencia de la alteración en el país, en la práctica clínica es usual encontrarla. También se conoce que los testículos retenidos tienen mayor riesgo de desarrollar neoplasias y presentar torsión (especialmente en los testículos neoplásicos) (3,4). Debido a las implicaciones clínicas y la heredabilidad de la condición, se recomienda orquiectomía.…”

Criptorquidectomía laparoscópica en dos perros utilizando bisturí ultrasónico

RESUMENTradicionalmente, los perros con testículos retenidos abdominales son remitidos para orquiectomía a través de laparotomía media ventral o paraprepucial. Sin embargo, las técnicas mínimamente invasivas realizadas a través de equipos endoscópicos, son una alternativa excelente para efectuar el procedimiento, debido a las ventajas en la reducción del trauma tisular y un menor dolor posoperatorio, además de la reducción de complicaciones posquirúrgicas entre otras ventajas. A continuación se presentan dos casos de pacientes caninos criptórquidos intervenidos quirúrgicamente mediante laparoscopia, para la extracción de los testículos retenidos en las que además se utilizó un bisturí ultrasónico. En Colombia, el desarrollo de las técnicas endoscópicas en cirugía de pequeños animales aún se encuentra muy limitado, y probablemente esta sea la primera publicación en el país acerca del uso de laparoscopia en casos de orquiectomía en pacientes con testículos retenidos en la cavidad abdominal.Palabras clave: Criptorquidismo, laparoscopia, perro (Fuente: CAB). ABSTRACTTraditionally, dogs with abdominally retained testicles are submitted to orchiectomy throughout a ventral midline or parapreputial laparotomy. However, minimally invasive techniques performed using endoscopic equipment are an excellent alternative for the abdominal procedure, because of the advantages in tissular trauma reduction, less postoperative pain and reduction in complications among other advantages. Two cases of abdominal cryptorchidectomy performed using minimally invasive techniques and ultrasonic scalpel in dogs, are presented in this report. In Colombia, the development of minimally invasive techniques in small animal surgery is still very limited, and this is possibly the first publication in the country regarding the use of this technique in two cases of abdominal cryptorchidism in dogs.
