Solitary fibrous tumor (SFT) of the breast is a rare mesenchymal tumor composed of spindle-shaped tumor cells with collagen and large blood vessels in the shape of a staghorn. It is discovered anywhere in the human body, usually incidentally or through nonspecific symptoms. A combination of clinical, histological, and immunohistochemical features is required to establish a diagnosis. There are no proper guidelines for the treatment of SFTs because of their rarity; however, wide surgical excision remains the gold standard. A multidisciplinary team approach is recommended. They are mostly benign with a 5-year survival rate of 89%. Following a PubMed-indexed English literature review, only six publications presenting nine cases of breast SFT in a male patient were found. The following is the case of a 73-year-old man who presented with dry cough. A SFT in the right breast was discovered incidentally during the investigative work up, and the patient was referred to our Breast Clinic at the Jules Bordet Institute, Brussels, Belgium, for appropriate treatment. The patient s presentation, imaging, and histological sample all supported the diagnosis, and he underwent uneventful surgical resection. Here, we present the first case of an incidental finding of a SFT of the male breast, with its diagnosis and therapeutic challenges.
