Abdominal ultrasonography revealed numerous heterogeneous oval structures, predominantly hypoechoic, with some present in the central region filled with cloudy liquid, measuring from 0.80 x 1.23 cm to 1.47 x 4.81 cm, presence of free fluid with cloudy appearance, rich in debris, a diffuse increase in abdominal echogenicity compatible with peritonitis (Figure 1A and 1B), and an absence of uterus and ovaries.

During laparotomy, diffuse peritonitis, abscess points, and the presence of purulent secretions were observed in the cavity, in addition to several reddish nodules of varying sizes implanted throughout the abdominal cavity (mesentery, omentum, liver, and spleen) (Figure 2A and 2B).
Presence of numerous round to oval cells with multivacuolated cytoplasm. Many cells have more than one nucleolus. Other cytological features of TVT are the granular appearance of karyoplasm owing to chromatin agglomeration and an increased nucleus:cytoplasm ratio.

Histopathological analysis of the abdominal nodules revealed a round cell neoplasm, morphologically compatible with a TVT or large cell lymphoma (Figure 3).
