A 52-year-old Cypriot woman was admitted to the surgical department of Larnaca General Hospital complaining of diarrhea and pain in the right upper and lower quadrants, which was reproduced by clinical examination. A palpable mass was also felt in the region. The white blood cell count was 8420/mul: 73.9% neutrophils, 13.3% lymphocytes and 6.9% eosinophils. Erythrocyte sedimentation rate was 80 mm/h. Parasitic examination of the stools was negative. A colonoscopy located a small mass near the ileoceacal valvule, which was sent for a biopsy. A barium enema and computed tomography scan revealed the same lesion to have expanded into the ascending colon. Despite negative biopsy reports, other findings suggestive of colon cancer prompted us to perform a right hemicolectomy and ileotransverse end to side anastomosis. The mass was found to be expanding into the surrounding fat tissue and into the regional lymph notes. Surprisingly, histological examination of the mass revealed visceral larva migrans, owing to ascaris Toxocara canis or Toxocara cati.

Toxocara canis is an important roundworm of canids and a fearsome animal parasite of humans. Human infections can lead to syndromes called visceral larva migrans (VLM), ocular larva migrans, neurotoxocariasis, and covert toxocariasis. VLM is most commonly diagnosed in children younger than 8 years of age, but adult cases are relatively frequent among those infected by ingesting the raw tissue of paratenic hosts in East Asia. This research reports the case of a 59-year-old man with sigmoid colon cancer, who visited our institution for surgery. An intraperitoneal mass was found on preoperative computed tomography, and it was thought to be a metastatic mass from sigmoid colon cancer. A postoperative histologic examination and serum test showed eosinophilic granuloma due to toxocariasis. Diagnosis of VLM is often difficult and highly suspicious in adults. Researchers suggest, although rarely, that VLM be included in the differential diagnosis as a cause of intraperitoneal tumors.
