Chasing the uncommon: Intra-Abdominal Testicular Tumors case report

Undescended testicles, a common congenital anomaly, can increase the risk of developing testicular tumors. This case report presents the unique occurrence of an intra-abdominal testicular tumor in a 30-year-old male with a history of cryptorchidism. The patient experienced persistent hypogastric pain, and diagnostic evaluation revealed elevated tumor markers, further indicating the presence of a testicular tumor. Surgical exploration confirmed a 256g differentiated seminoma within the peritoneal cavity. The discussion highlights the increased risk of malignancy associated with cryptorchidism, the limited preventive impact of orchidopexy, and the challenges in early diagnosis due to the non-palpable nature of these tumors. It emphasizes the need for awareness, early diagnosis, and ongoing research to improve the management of intra-abdominal testicular tumors in individuals with cryptorchidism and enhance patient outcomes.

A giant intra-abdominal right testicular seminoma in a bilateral undescended testicle: a case report

Cryptorchidism is the most common congenital malformation of the male genitourinary tract. An undescended testicle has a 10% chance of developing cancer, with an intra-abdominal testicle having the highest risk. We present a 24-year-old man with a history of bilateral cryptorchidism, complaining of lower abdominal mass for two months. An abdominal computed tomography scan showed an intra-abdominal mass lesion measuring 13 x 9 cm and displacing the bladder caudally. Exploratory laparotomy revealed a right intra-abdominal testicular tumor. A right orchiectomy and left orchidopexy was performed. Histopathological examination revealed a testicular seminoma. The patient was discharged without complications and was referred to the oncology department for chemotherapy and further management. Our findings support the early treatment and close monitoring of cases of cryptorchidism due to the risk of malignancy as well as the necessity of routine scrotal examinations in all males presenting with an abdominal mass.

Infantile pure yolk sac tumor of testis - A case report

Intra-abdominal testicular tumors are uncommon in prepubertal children. The present study is a rare case of intra-abdominal testicular yolk sac tumor with elevated Alpha feto protein levels whose diagnosis was confirmed by histopathology and immuniohistochemistry. Serum tumor markers and radiological examination also aids towards the diagnosis of nonpalpable undescended testis. Keywords Undescended testis, Tumor markers

Yolk sac tumor in intraabdominal undescended testis in a child with normal serum alpha-fetoprotein: a rare case report

BackgroundIntraabdominal testicular tumors are rare in prepubertal children, and most of the cases reported are intraabdominal testicular teratoma. The present study reports the first case of intraabdominal testicular yolk sac tumor (YST) with normal preoperative serum alpha-fetoprotein levels and diagnosis confirmed on histopathology and immunohistochemistry.Case PresentationA 2-year-old boy presented with bilateral nonpalpable undescended testes (UDT) and abdominal mass. Preoperative serum alpha-fetoprotein was normal. Contrast-enhanced computed tomography (CECT) scan of whole abdomen revealed a heterogeneous mildly enhancing space-occupying lesion in midline and left side of pelvis, left intraabdominal testis and nonvisualization of right testis. During surgery, the mass was found to involve right testis with one turn of torsion of its pedicle. Derotation of testis was performed, and right radical orchiectomy was performed. Left orchiopexy was also performed at the same time. Histopathology and immunohistochemistry confirmed diagnosis of intraabdominal testicular YST. There was no recurrence or distant metastasis at 12-month follow-up after surgery.ConclusionIn a case of nonpalpable UDT and abdominal mass/pain, one should always consider possibility of intraabdominal testicular tumor and should investigate the case with serum tumor markers and ultrasound/CECT abdomen. Further, histology of tumor helps in guiding treatment of condition.

Laparoscopic resection of prenatally detected intra-abdominal testicular teratoma: Report of a neonatal case

Abstract Prenatal detection of intra-abdominal testicular tumor is rare. In this paper, we discuss the early laparoscopic resection of prenatally detected testicular tumor of a neonate. At 33 weeks gestation, follow-up ultrasound showed the mass measuring 3 × 2 cm, on the fetal right lower quadrant. After full-term birth, we performed laparoscopic resection of the tumor, on day 14 of life. Histology of 4-cm right testicular tumor revealed immature teratoma. Postoperative course was favorable and no recurrence has occurred 3 years after operation. Prenatal diagnosis of the intra-abdominal testicular teratoma enabled the early tumor resection, and laparoscopic resection of the tumor is safe and feasible, even in a neonate.

Tumor in undescended intrapelvic testis revealed by supraclavicular lymphadenopathy: a case report and literature review

BackgroundTesticular cancer is a rare disease. The incidence of testicular cancer in undescended testicles is of 3 to 48 times greater than in the general population. In the developed countries, the existence of undescended testicles in the adult population is rare, due to systematic practice of elective orchidopexy before the second year of life and orchiectomy in post adolescent males with undescended testicles. Despite these prevention measures, there are still some isolated cases of intra-abdominal testicular tumors in adults. We report a case of testicular cancer in cryptorchid testis revealed by supraclavicular lymphadenopathy.Case presentationWe report a case of a 46 year old fertile man with a history of unilateral cryptorchidism who presented with a palpable left supraclavicular mass and absence of the right testicle. On investigations an intrapelvic testis tumor was diagnosed. Laparotomy and complete excision was carried out. The possible association between the undescended testis and cancer transformations is briefly discussed.ConclusionTesticular cancer in undescended testicles should not be ignored. Only early diagnosis and lower of testis in scrotumprevent such clinical forms.

Torsed intraabdominal testicular tumor diagnosed during surgery performed due to suspicion of acute appendicitis.

Intra-abdominal neoplasmatic testicular torsion is a very rare clinical condition, which is normally not considered during differential diagnosis of acute appendicitis. The above-mentioned is most often observed in patients after puberty, without any previous specific symptoms apart from the absence of the testis in the scrotum and inguinal canal or periodic pain in the right lower abdomen. The study presented a case of a 22-year old male patient who was admitted and operated with suspicion of acute appendicitis. During surgery we observed intra-abdominal testicular torsion, both the testis and appendix were excised. Postoperative histopathological results were as follows: seminoma of the testis and normal appendix. The study presented available data concerning the above-mentioned rare clinical condition, as well as principles of diagnosis and treatment.

Spontaneous Rupture Of An Intra-Abdominal Testicular Tumor: A Case Report

The rupture of an intra-abdominal testicular tumor is a rare cause of acute abdomen with haemoperitoneum. We report a case of a 25-year-old male presenting with acute abdomen with haemoperitoneum caused by the rupture of intra-abdominal a nonseminomatous, mixed germ cell testicular tumor (NSMGCT), a predominantly yolk sac tumor and embryonal carcinoma in an undescended testis. The clinical details and difficulties in diagnosis of this testicular tumor are discussed.

Intra-Abdominal Testicular Seminoma in a Woman with Testicular Feminization Syndrome

We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had described the combined role of CT and MR imaging in intraabdominal testicular sex-cord stromal tumor. To our knowledge, this case is first to document USG and MR imaging in addition to MR spectroscopy features in intraabdominal testicular seminoma.

Unresolved abdominal mass in an adult cryptorchid testis: a case report

This case study aims to report an unresolved abdominal mass in an adult with cryptorchid testis and provide a review of related literature. We investigated a 54-year-old man who had cryptorchidism with a history of left orchiectomy 18 years prior. He was diagnosed with an intra-abdominal testicular mass after referring to the emergency ward with pelvic pain. The incidence of testicular cancer in undescended testicles is 40 times greater in the general population. In developed countries, the existence of undescended testicles in adult population is rare, which could be due to systematic practice of elective orchidopexy before the second year of life as well as orchiectomy in post-adolescent patients with undescended testicles. Despite these preventive measures, there are still some isolated cases of intra-abdominal testicular tumors in adults.

Mature teratoma arising from an intraabdominal testis in a 2-month-old boy: case report and review of intraabdominal testicular tumors in children

Tumors arising in an undescended testis are rare in infants. We report a mature teratoma in an intraabdominal testis of a 2-month-old boy. He presented with a large left-sided abdominal mass and nonpalpable left testis. Abdominal ultrasound and computed tomography showed a well-defined, sizable cystic tumor with focal calcification in the lower abdomen. Tumor markers were all within normal limits. Surgical resection revealed a large tumor arising from an intraabdominal left testis, and histologic analysis identified a mature teratoma. The tumor was completely removed, and there was no recurrence at follow-up 3 years later. The histologic condition of prepubertal intraabdominal testicular (IAT) tumors is quite different from that of testicular tumors in childhood descended testes and postpubertal IAT tumors. A total of 30 cases of IAT tumors in children, including our case, were reviewed to elucidate this issue.

Minimal Invasive Surgery in Pediatric Solid Tumors

There is only limited experience of using the minimally invasive surgery (MIS) technique in resecting pediatric solid tumors. In this paper, we report our experience of using the MIS technique in the management of pediatric solid tumors. A retrospective review was undertaken on all children who had undergone MIS for their solid tumors between 1995 and 2005. Over a 10-year period, there were 38 patients who had undergone MIS for tumor resection. The mean age at the time of surgery was 7.5 years (range, 1 day to 15 years). There were 22 ovarian tumors, 4 sacrococcygeal tumors, 3 adrenal tumors, 3 retroperitoneal tumors, 1 kidney tumor, 1 liver mass, 1 intra-abdominal testicular tumor, and 3 intrathoracic masses. Thirty of 38 patients had undergone a successful resection using the MIS technique (78.9%). Eight patients required a conversion to the open procedure because of limited intraperitoneal space in 7 and excessive bleeding in 1. Of the 28 successfully MIS-resected intra-abdominal tumors, 18 required enlargement of the umbilical incision and 5 required an additional Pfannenstiel incision for tumor retrieval. Enlargement of the thoracic port site for specimen retrieval was required in the 2 successfully MIS-resected intrathoracic masses. The mean operation time was 171 minutes (range, 45-275). There was no postoperative complication encountered. On an average follow-up of 3.1 years, there was no recurrence observed, even in the 7 patients with malignant tumors, and all patients with successful MIS tumor excision had good cosmetic results. With the advance of laparoscopic instruments and techniques, a variety of pediatric solid tumors can be resected safely by the MIS technique. This has the potential benefit of a more rapid postoperative recovery and better cosmetic results. The role of the MIS technique in resecting malignant tumors is uncertain, as the number of cases in the current series is too small to draw any conclusion.

Seminoma de testículo abdominal en un paciente adulto: reporte de un caso

ObjectiveTo present a new case of an Intra-abdominal Testicular Seminoma in an adult Methods/resultsWe report a 30 year old patient with cryptochidism, that after consulting to the emergency service due to abdominal pain, was diagnosed an Intra-abdominal Testicular Seminoma DiscussionThe incidence of testicular cancer in cryptorchidic testis is 3 to 48 times higher than in general population. The existence of maldescended testis in adult population is rare in developed countries, due to the normal practice of elective orchidopexia in children under 2 years old and orchiectomy in maldecended testis in postpuberal pacients. In spite these measures of prevention, there are still isolated cases of Intra-abdominal testicular tumors in adults

Mature teratoma arising in intraabdominal undescended testis in an infant with previous inguinal exploration: Case report and review of intraabdominal testicular tumors in children

The authors report the youngest case of postoperative intraabdominal mature testicular teratoma in a 5-year-old boy after previous exploration for impalpable testis. A total of 26 cases of intraabdominal testicular tumor in children including our case were reviewed and discussed from both the English- and the Japanese-language literature. The average age was 2.5 years, and, in the 13 children younger than 1 year there were no malignant teratomas, although there was one immature teratoma. Four of these had undergone previous inguinal exploration in which 3 patients except our patient were more than 10 years old. This case report confirms the importance of finding an intraabdominal testis at operation for impalpable testis. Early detection of the testicular location near the internal inguinal ring in these patients supports the hypothesis that the intraabdominal testicular teratoma itself may have been the primary cause of the undescended testis. Furthermore, it is suspected that many of the intraabdominal testicular malignant teratomas in adults may have arisen from these mature testicular teratomas in infants. J Pediatr Surg 37:1236-1238.

Torsion of an intraabdominal testis tumor presenting as an acute abdomen

Torsion of an intraabdominal testicular tumor is a rare preoperative diagnosis. An increased diagnostic yield is dependent on an expedient and comprehensive preoperative evaluation. This consists of a detailed past surgical history, a thorough physical examination, and close inspection of the preoperative abdominal films. An illustrated case report is presented.
