[Mixed colon tumour: leiomyoma-haemangioma]

Leiomyoma and heamangioma of the colon are extremely rare tumours. Only 27 cases were published in world literature up to 1954. A few new were published after that period. We describe a 46-year-old man with 3-months-history of occlusive symptoms in whom during the operation for complete colon obstruction mixed colon tumour (leiomyoma-haemangioma) was found, 10 cm distal to hepatic flexure. The tumour was of intraluminal pedunculated type", 7 cm in maximal diameter. Four enlarged, firm lymph nodes in the mesocolon close to the tumour were found. Right colectomy was carried out as the most resonable procedure. Histopathology showed leiomyoma of the colon with massive fibrous tissue, degeneration, bleeding of the tumour and many dilated blood vessels, so that its pedunculated part resembled a haemangioma. No sign of malignancy was found. The recovery of the patient was normal, and he stayed symptom-free, with normal small bowel function, clinical and laboratory data.
