Solitary Sclerotic Fibroma

Sclerotic fibroma (SF) or storiform collagenoma is a rare and benign skin tumor. Clinically, it usually presents as an asymptomatic, slowly growing papule or nodule on the skin of the head, neck and upper extremities. Other locations have been described including the trunk, oral mucosa and nail bed. SF can present either as a solitary tumor or as multifocal cutaneous lesions and it may occur sporadically or in association with Cowden syndrome. Herein, we report a case of a solitary SF with typical clinical and histologic features, not associated with Cowden disease.

Enlarging left atrial haemangioma in a patient with Cowden syndrome

A 53-year-old female patient known to have Cowden disease (PTEN mutation positive) was found to have a mass at the left atrium on a CT coronary angiography performed as part of a preoperative workup for an unrelated surgery. Further radiological characterisation of the lesion was achieved using MRI and positron emission tomography. Interval growth prompted surgical excision; however, surgery was expedited after the patient presented with haemopericardium and cardiac tamponade. The patient was discharged home 8 days postoperatively, and no intraoperative or postoperative complications were encountered. A diagnosis of cavernous haemangioma was made on histology.
