Primary Renal Carcinoid: Two Rare Cases at a Single Center

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Renal carcinoid tumors are exceptionally rare neuroendocrine neoplasms.
• Most commonly originate in the gastrointestinal and respiratory systems.
• Fewer than 100 cases have been documented globally.

Observation:

• Two new cases of renal carcinoid tumors in female patients (ages 53 and 63) are presented.
• Both tumors were incidentally discovered via computed tomography (CT) scans.
• Both patients underwent radical nephrectomies for tumor removal.

Findings:

• Neither patient has shown evidence of metastasis or tumor recurrence post-surgery.
• The 63-year-old patient was lost to follow-up.
• Radical nephrectomy was performed successfully in both cases.

Implications:

• Renal carcinoid tumors should be considered in the differential diagnosis of asymptomatic renal masses.
• Early detection and surgical intervention, such as radical nephrectomy, appear effective.
• Further research is warranted to understand the behavior and optimal management of these rare tumors.
