VSD following blunt cardiac trauma: MRI findings.

In this report, we describe the clinical and radiographic findings of ventricular septal defects (VSDs) following blunt cardiac trauma in two patients. VSDs following either penetrating or blunt cardiac trauma are a rare occurrence. The variable presentation and timing of symptom onset along with the common association of other injuries can make the diagnosis of a posttraumatic VSD difficult. Therefore, investigation should be initiated when elements from the history and physical examination (e.g., new onset murmur), laboratory tests (e.g., cardiac enzymes), EKG, and CT or echocardiography warrant it. The first patient was a 19-year-old male who was hemodynamically stable on initial presentation to this trauma center after a motor vehicle collision. A posttraumatic VSD was found by echocardiography on the day of admission and further defined on cardiac MRI (CMRI). The second patient was a 31-year-oid male who presented after a high-speed motorcycle accident and was found to have a VSD 40 days later on CMRI after a fluctuating clinical course and multiple normal echocardiograms. Both patients had good outcomes with subsequent surgical closure.

Acquired trichostasis in postoperative site: a case report.

INTRODUCTION: Usual causes of a papule or nodule in a post-operative site after resection of a skin tumor are residual or recurrent tumor, proliferative scar, or suture granuloma with inflammation and granulation tissue. Inverted or trapped hair, an acquired trichostasis, has not been implicated as a cause in such cases, this is probably the first case reported in literature. CASE PRESENTATION: A 31-year-old woman underwent an excision of a ruptured epidermal cyst of the left axilla. One month later, the previous excision site was re-excised secondary to a non-healing, inflamed papule in order to exclude recurrent epidermal cyst formation. Microscopic examination revealed that the cause of the papular lesion was acquired trichostasis, rather than a recurrent epidermal cyst. CONCLUSION: A papular or nodular lesion at a postoperative site may rarely be caused by acquired trichostasis and should be considered as one of the differential diagnosis.
