RESUMEN
Squamous cell carcinoma (SCC) of the colon is a rare tumor that accounts for 0.1%-0.2% of colonic malignancies. However, pure SCC of the cecum is extremely rare. Although SCC of the colon is a rare complication of idiopathic inflammatory bowel disease (IBD), SCC of the cecum in the context of IBD has not been previously reported in the English literature. We report a case of the coexistence of SCC of the cecum and a carcinoid tumor in a 46-year-old female with long-standing pan-ulcerative colitis.

A 40-year-old woman presented with a 1 year history of a painless, subcutaneous lump on the right buttock. Clinical examination showed an approximately 6 cm large subcutaneous mass covered by apparently normal-looking skin. No inguinal lymphadenopathy was found. The mass was excised with the clinical diagnosis of fibroma. Histologically, the lesion was consistent with mammary-type myofibroblastoma of soft tissue, a very rare, benign mesenchymal neoplasm with myofibroblastic differentiation. After surgical excision she was free of recurrence over a period of 8 months. This article also challenges the theory that suggests the origin of this tumor to be from the embryonic mammary tissue, adding another case of a site other than the milk lines.
