Vogt-Koyanagi-Harada disease-like uveitis induced by nivolumab in metastatic renal cell carcinoma.

Introduction: Nivolumab can cause various immune-related adverse events; it rarely induces Vogt-Koyanagi-Harada-disease-like uveitis. Vogt-Koyanagi-Harada-disease is reported to be closely associated with human leukocyte antigen-DR4.

Case Presentation: A 68-year-old man with metastatic renal cancer underwent nephrectomy.

Urodynamic findings and vibegron effects on neurogenic lower urinary tract dysfunction caused by human T-cell leukemia virus type I-associated myelopathy/tropical spastic paraparesis.

Introduction: Human T-cell lymphotropic virus type 1 infection can cause HTLV-1-associated myelopathy/tropical spastic paraparesis, characterized by spastic paralysis of both lower limbs. More than 90% of HAM/TSP patients show lower urinary tract symptoms and dysfunction.

Case Presentation: A 27-year-old woman diagnosed with HAM/TSP presented with overactive bladder.

CHARGE syndrome with both primary and secondary hypogonadism.

Introduction: CHARGE syndrome is a rare disorder that causes congenital abnormalities in multiple organs, including secondary hypogonadism. We report, herein, a unique case of CHARGE syndrome with both primary and secondary hypogonadism and discuss the possible causes and pathogenesis in this patient.

Case Presentation: A 15-year-old boy with delayed secondary sexual characteristics and non-palpable testes was referred to our hospital.

Coincidental occurrence of bilateral neonatal testicular torsion, with an extravaginal and a contralateral intravaginal testicular torsion.

Introduction: We report a case of bilateral neonatal testicular torsion, with an extravaginal and a contralateral intravaginal testicular torsion.

Case Presentation: A 5-day-old boy with bilateral scrotal swelling and palpable induration was diagnosed with bilateral neonatal testicular torsion by color Doppler ultrasonography. The right testis was black with 360-degree extravaginal torsion of the spermatic cord, and the left testis was brown with 90-degree intravaginal torsion.

-deficient basal cell carcinoma of the prostate controlled using radiation therapy.

Introduction: Basal cell carcinoma of the prostate is rare, with no established treatment for its recurrence or metastasis. We report a case involving basal cell carcinoma of the prostate controlled using radiotherapy.

Case Presentation: A 57-year-old man complained of perineal pain.

Congenital lipoid adrenal hyperplasia: Immunohistochemical study of testosterone synthesis in Leydig cells.

Introduction: Congenital lipoid adrenal hyperplasia is a rare disease that causes disorders of sex development. The 46,XY patient presents with female external genitalia and inguinal testes. We describe the case of a patient with congenital lipoid adrenal hyperplasia and investigated the testes of this patient in detail.

Spindle cell renal cell carcinoma diagnosed after sunitinib treatment for chromophobe renal cell carcinoma.

Introduction: Chromophobe renal cell carcinoma presents in early pathological stages with a lower risk of metastasis. However, aggressive features and metastasis can occur. A rare case of rapidly progressive disease with histological changes is presented.

Delayed diagnosis of intraperitoneal bladder perforation after blunt trauma.

Introduction: Intraperitoneal urinary bladder perforation due to blunt trauma in intoxicated patients requires quick and accurate diagnosis. However, this is difficult to correctly diagnose in intoxicated patients because their symptoms can be masked. We describe a rare case of intraperitoneal urinary bladder perforation that occurred after blunt trauma.
