Unusual Case of Laryngeal Squamous Cell Carcinoma with Cervical Metastasis of a Prostatic Adenocarcinoma: A Case Report

Abstract

Brain and Head and neck metastases are rare in prostatic carcinoma patients. In this report we present a very uncommon case of the concomitant occurrence of a prostatic adenocarcinoma with neck metastases and an advanced laryngeal squamous cell carcinoma without neck metastases. The presence of cervical lymph node prostate adenocarcinoma metastasis concomitantly with a laryngeal squamous cell carcinoma is at least intriguing and may remind us of a rare event called “collision tumors”. In this case we had the metastatization of 1 carcinoma to the site of the drainage of another carcinoma, but we never found the 2 histological types as close as requested to reach the definition of a collision tumor. This emphasizes the need of histological verification of different sites of recurrence when 2 or more primary cancers are known in a patient, particularly when the treatments of those primary cancers vary widely.

Four-Cell Population Collision Tumor of the Scalp: A Case Report and Review of Literature

“…Five reviewed articles documented recurrent distal metastasis within 3 to 12 months after initial treatment. [15][16][17][18][19] Lymph node infiltration did not suggest any correlation with distal metastasis following treatment. There were reported deaths for 3 of those patients.…”

“…There were reported deaths for 3 of those patients. [16][17][18] The reviewed literature revealed the growing discoveries regarding HNCTum. Although rare in occurrence, evidence suggests that the current treatment options have been successful at minimizing metastasis.…”
