Differential diagnosis and treatment of rare forms of primary peritoneal tumors – solitary fibrous and desmoplastic small round cell tumors

Solitary fibrous tumor and desmoplastic small round cell tumor are primary peritoneal malignant tumors. Despite their morphological differences, these diseases are united by low morbidity, the lack of pathogenic symptoms, similar radiological signs, and scant knowledge of prognostic factors.

According to the available information, the treatment of desmoplastic small round cell tumors is based on multimodal therapy, including systemic chemotherapy and surgery, and possibly radiation therapy.
