Sclerosing angiomatoid nodular transformation of the spleen: a case report

Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an uncommon primary benign condition with specific histopathological characteristics. The majority of the patients are usually asymptomatic and present for treatment after an incidental finding on a routine abdominal imaging. The differential diagnosis includes other benign tumours, as well as primary malignancy or metastases of unknown origin. We report a 55-year-old woman who was presented to the surgical team of our hospital for splenectomy after the investigation of an incidental splenic lesion led to the diagnosis of SANT. The pathology report of the specimen repeated the initial diagnosis. The patient has not yet presented any complication or recurrence of the disease 8 months after the operation. From such infrequent cases, the most valuable conclusion which can be yielded is that the more the number of patients reported, the more the knowledge about the disease is broadened.

Unusual Case of Sclerosing Angiomatoid Nodular Transformation of the Spleen in an Adolescent Patient: Case Report and Literature Review

Sclerosing Angiomatoid Nodular Transformation (SANT) is a rare and benign lesion arising from the red pulp of the spleen, with an unknown etiopathogenesis. These tumors are usually asymptomatic and are found incidentally on radiographic examination. Therefore, high clinical suspicion is of great importance for the diagnosis. Splenectomy provides complete cure, and no recurrence and/or malignant transformation was reported to date. In this study, a rare case of SANT was reported in aadolescent male, and was discussed with the relevant literature.

Sclerosing angiomatoid nodular transformation of spleen: an uncommon benign lesion of spleen

SANT (sclerosing angiomatoid nodular transformation) is a rare benign vascular tumour of spleen. SANT can mimic benign and malignant conditions of spleen. There are no definite radiological features. It has characteristic histopathology and immunohistochemistry findings which help us to differentiate it from other angiomatoid and tumor-like lesions. Splenectomy is the treatment of choice as it is diagnostic and therapeutic at the same time. We present a case of 22 years female with left upper quadrant pain since, 2 months. Magnetic Resonance Imaging revealed well-defined hypodense mass measuring 6.3×6.1×5.8cm in the spleen, with provisional diagnosis of hemangioma. Laproscopic splenectomy was done and a diagnosis of SANT was made on histology and immunohistochemistry. This case shows us that SANT should be considered in the differential diagnosis of splenic solid lesions.
