A case report of a large Splenic epidermoid cyst treated with partial splenectomy.

INTRODUCTION AND IMPORTANCE: Splenic epidermoid cysts are rare primary congenital cysts composed of an epithelial lining that represent a small proportion of nonparasitic splenic cysts. Despite their infrequency, there is a lack of uniform diagnostic and treatment guidelines for these cysts, emphasizing the need for further research and standardized reporting.

CASE PRESENTATION: A 45-year-old female presented with left upper quadrant abdominal pain, characterized by a pressing sensation. Physical examination revealed a palpable mass in the upper left quadrant. Laboratory test results were normal. Abdominal ultrasonography and CT tomography confirmed a large splenic unilocular cyst consistent with an epidermoid cyst. Surgical intervention involved aspiration of the cystic fluid, partial splenectomy, and pathological examination. The patient's postoperative recovery was uneventful.

CLINICAL DISCUSSION: The origin of splenic epidermoid cysts remains unclear, with theories suggesting entrapment of mesothelial cells during embryonic development. The clinical presentation varies with cyst size, often causing abdominal pain and a palpable mass. Diagnostic modalities include ultrasonography and CT scans. Surgical intervention is recommended for symptomatic or suspicious cysts to prevent complications. The chosen approach depends on cyst characteristics and patient factors. This case highlights the challenges and considerations in managing splenic epidermoid the cysts and emphasizes the need for individualized treatment approaches.

CONCLUSION: This case contributes to the understanding of splenic epidermoid cysts and demonstrates a successful subtotal splenectomy as a treatment approach. Further research and standardized guidelines are essential to improve the management of these rare lesions and to provide better insights into their etiology and optimal treatment strategies.
