Penile metastasis from primary cholangiocarcinoma: the first case report

Abstract

BackgroundMetastatic penile carcinoma derived from cholangiocarcinoma (CCA) has not been previously reported in the literature. Common metastatic sites for CCA include the regional lymph nodes and adjacent organs. CCAs are not highly vascularised tumours, making hematogenous metastases uncommon. Hematogenous CCA metastases commonly occur at distant organs such as the lungs, adrenal glands, and bones. Median survival for patients with metastatic disease is generally less than 1 year.Case presentationA 74-year-old Caucasian man consulted us after having undergone penile ultrasonography for pain and increased thickness at the base of the penis after self-examination. The patient presented with a history of hepatitis C-related cirrhosis and intrahepatic CCA, diagnosed 3 years previously. A biopsy of the corpora cavernosa on both sides revealed a carcinoma harbouring the same histological and immunophenotypical features as the primary hepatic lesion.ConclusionsTo date, there is no case of penile or urogenital system metastasis from CCA described in the literature. Therefore, this article represents the first case report of penile metastasis from CCA.

Penile and intramuscular metastases from esophageal squamous cell carcinoma: A rare case report and review of the literature

“…The most common symptoms and signs in order of frequency are priapism, urinary retention, penile nodules, ulcer formation, perineal pain, edema, generalized swelling, broad infiltrative enlargement, dysuria, and hematuria. 2 Our patient presented with penile nodule and intramuscular mass in the thigh, which is extremely rare. The patient was offered systematic chemotherapy and local radiotherapy and got partial relief.…”

Collision tumor comprising metastatic cholangiocarcinoma and seminoma in an undescended testis: a case report

“…9 The most common metastatic sites of ICC include the lymph nodes, peritoneum, lungs, and pleura. 10 ICC metastasis to the male urogenital tract is rare; [11][12][13] only two cases of testicular metastasis of ICC have been reported. 3,4 Our patient was initially diagnosed with ICC, with no evidence of seminoma at that time.…”

Cholangiocarcinoma Presenting as Linitis Plastica with Unusual Metastases to the Psoas Muscle and Urinary Bladder

“…With respect to the genitourinary system, no published cases involve the urinary components of the genitourinary system; the current literature regarding metastatic cholangiocarcinoma include only the penis, uterus, and ovary. 9 - 11 Bladder metastasis along with infiltration of the left psoas muscle may have contributed to hydronephrosis and acute kidney injury.…”
