BACKGROUND: Spleen Hamartoma is an uncommon lesion. Approximately one-hundred and fifty spleenic hamartomas have been described in literature. AIM: This article relates a case of spleenic hamartoma and revises clinical and pathological findings pertaining this subject in literature. CASE REPORT: A 54 year-old woman complained of full stomach sensation and increased abdominal volume for two years. She denied vomiting or having any intestinal alteration, as well as no weight loss. Upon physical examination, an overall good state of health was observed, except for a flacid abdomen, painful upon deep palpation in the left hyponchondrium area, showing a palpable mass at approximately 8 cm from the left rebordo costal, as well as hidroairy sounds. Laboratory exams showed no alterations. Computerized tomography of the abdomen showed an increased volume of the spleen due to an expansive volumous formation, heterogeneous, containing a hypodense (cystic) liquid and rough septation with underlying calcifications foci measuring about 14,0 x 16,0 x12,0 cm in diameters longitudinally, antero-posteriorlly and transversally respectively. The patient was submitted to exploratory laparotomy, where no tumors in the peritoneal cavity were observed, allowing spleenectomy to be persued without interventions. Macroscopic exams of the surgical segment showed an increased spleen, weighing 1,170 and measuring 23,0 x 14,5 x 10,0 cm. The attention was called to a volumous mass weighing 14,5 x 10,0 cm. Through hystopathological and immunohistochemical exams, it was concluded that the mass was an hamartomous tissue without any malignancy. CONCLUSION: The harmartoma is a benign rare tumor, nevertheless it should be recalled during differential diagnosis of unknown masses originated in the spleen, making spleenectomy a safe and effective procedure.
