Background: The present study aims to present a case series of patients who underwent splenectomy for splenic primary solid tumors without preoperative histopathologic diagnosis.
Methods: From 2013 to 2019, 12 patients underwent splenectomy for solid primary splenic tumors at 3 different academic medical centers. All electronic medical records were retrospectively reviewed.
Results: Seven (58.3%) patients were women, and 5 (41.6%) were male. The median age was 48 years (range: 25-72 years). In 8 (66.6%) patients, a conventional approach was performed. In 2 (16.6%), a hand-assisted laparoscopic surgery procedure was completed, and in other 2 (16.6%) patients, a laparoscopic approach was auspiciously achieved. Median operative time was 135 minutes (range: 60-210 minutes), and median blood loss was 500 mL (range: 200-1500 mL). Procedure-related morbidity was found in 2 (16.6%) patients, and the mortality rate was 0%. The final histopathologic diagnosis was lymphoma in 5 (41.6%) patients, lymphangioma in 3 (25%) patients, hamartoma in 2 (16.6%) patients, angiosarcoma, and sclerosing angiomatoid nodular transformation (SANT) in 1 (8.3%) case each.
Conclusion: Splenectomy should be the treatment of choice when encountering a primary splenic tumor without the need for preoperative fine-needle aspiration biopsy, avoiding the complications this technique entails.
