Unusual Presentation of Prostate Cancer Metastatic to the Cricoid Cartilage and Oral Cavity

Abstract

In Mexico, prostate cancer is the second leading cause of death in men. Prostate cancer usually presents metastasis to the regional lymph nodes and bone. Hereby, we present an unusual case of metastatic prostate cancer, with affectation to the cricoid cartilage and oral cavity, being the first case to have ever been reported in Mexico. A 68-year-old Mexican man was diagnosed with prostate cancer and cribriform architecture histology with low serum level of prostate-specific antigen, debuting with laryngeal stridor. e biopsy came back positive for metastatic prostate carcinoma. During treatment with radiotherapy, metastasis developed to the oral cavity.

Metastatic thyroid cartilage lesion from prostatic adenocarcinoma on 68Ga-prostate-specific membrane antigen positron emission tomography-computed tomography scan: Case series

“…[ 6 ] Few cases have been described in literature previously of metastasis to cartilages of larynx. [ 8 9 10 11 12 ] The laryngeal metastases usually remain unnoticed and may or may not present with clinical symptoms. The same was seen in our series and none of the patient had any thyroid cartilage involvement symptoms and since multiple metastases were seen, the histopathological confirmation of the thyroid cartilage lesions was not done.…”

“…As for laryngeal metastases, only 13 cases have been reported as of 2001 in the literature, and 1 case was reported in 2018. 1 , 2 Recently, 18 F-fluorocholine PET and 68 Ga–prostate-specific membrane antigen (PSMA) PET/CT detected cricoid or thyroid cartilage metastases from prostate adenocarcinoma. 3 , 4 …”
