title: Rare cutaneous metastasis from a probable basaloid carcinoma of the colon mimicking pyogenic granuloma.
abstract: Acrometastasis is a rare occurrence, especially when affecting the hands. It represents around 0.007-0.2% of all metastatic lesions. The most common site of origin is the lung, accounting for 40-50% of all cases reported in the literature. Kidneys and breasts are other sites also associated with neoplastic lesions that disseminate to the hands. More rarely, the site of origin may be the gastrointestinal tract or other systemic tumors or sarcomas. Early diagnosis is difficult, since the condition may be asymptomatic or may mimic tenosynovitis, arthritis, paronychia, pyogenic granuloma or a local infection. In the present paper, the authors report on a patient with the diagnosis of acrometastasis on both hands originating from a basaloid carcinoma of the anal canal. Response to radiotherapy was poor.
