Benign masses are not uncommon near the Achilles tendon of the ankle. However, the occurrence of angiomyomas or glomus tumors in the region has rarely been reported. We describe two patients, a 44-year-old woman and 44-yearold man, who presented with a tender mass posterior to the Achilles tendon. Excision led to successful removal of the lesion in both cases. Results of histological examinations revealed an angiomyoma and glomus tumor in the woman and man, respectively. Although rare, the presence of these tumors should be considered in the differential diagnosis of masses near the Achilles tendon.
