Description
Shigeyuki Kosaka and eight colleagues report a case of aggressive angiomyxoma, a rare locally invasive tumour, arising in the anus of a 71-year-old man, a site never previously reported for this disease. The growth usually appears in the pelvic and perineal region of women and is extremely rare in men, where the scrotum or buttocks are typical sites.
The man was first diagnosed with prolapsed internal haemorrhoids of the most advanced grade and underwent surgery. Microscopy of the removed tissue unexpectedly revealed the tumour, positive for markers CD34 and desmin. Bleeding after surgery needed artery-blocking treatment through a catheter. Despite the tumour's high recurrence rate, he has stayed disease-free for over five years.
