A subsequent CT scan further elucidated an affected spleen, with possible metastatic or lymphoma-like changes (Fig. 1).

A cross-section of the spleen subsequently revealed a greyish-white discharge, with the organ itself measuring 16 x 12 x 10 cm (Fig. 2).

Purpura-like changes were further noted atop the greater omentum, as well as the wall and mesentery of the small bowel (Fig. 3).

At the sigmoid portion of the colon, immediately above the colorectal junction, a 2 cm tumour was observed (Fig. 4).

The regional lymph nodes were also removed, as was the spleen (Fig. 5).

Subsequent histological examination of the obtained samples evaluated them to be an adenocarcinoma of the sigmoid colon (G2, T3), an angiosarcoma of the spleen (G3), as well as lymph nodes that were affected by metastasis (Fig. 6).
