Synchronous Gastrointestinal Stromal Tumor and Axillary Deep Fibromatosis: A Rare Association

Gastrointestinal stromal tumor (gist) is the most common mesenchymal tumor of the gastrointestinal tract and most commonly affects the stomach, while fibromatosis is a rare locally aggressive fibrous tissue neoplasm. there have been reports of gist and fibromatosis occurring in same individual and in most of them fibromatosis occurs within the abdomen. in 75% of patients fibromatosis occurs after the diagnosis of gist while in 20% it is seen synchronously. here we report a case of axillary fibromatosis with synchronous gist of the gastroesophageal junction in a 45-year-old male treated with surgery and now on adjuvant imatinib.
