Abstract
BACKGROUND

Gallbladder cancer is the most common malignant tumor of the biliary tract. The majority of cases are adenocarcinoma. Squamous cell carcinoma is the histological type present in 12% of all neoplasias accounting for approximately 12% of gallbladder neoplasms. It can occur in its pure form reaching 1%-3% of the tumors. Many patients are at an advanced stage when diagnosed and have bad therapeutic efficacy.

CASE SUMMARY

A 45-year-old male patient presented with left flank pain for 1 year and irradiated to the mesogastric region. He denied fever, vomiting, and any other intestinal changes. He reported a weight loss of 10 kg in a period of 7 mo. He denied alcoholism, smoking, drug use, or prior illness. Computed tomography of the abdomen showed in the gallbladder fossa a voluminous mesogastric heterogeneous collection that had a thick and irregular capsule with liquid and gaseous contents. A predominantly hypoattenuating rounded material with partially calcified margins measuring about 2.0 cm related to gallstone was also emphasized. No lymphadenomegalies or free fluid was observed in the abdominal cavity. Patient underwent laparotomy where a huge tumor was observed affecting the transverse colon and gallbladder. This mass was resected en bloc removing gallbladder and transverse colon together with corresponding mesocolon and regional lymphadenectomy. There were no complications in the postoperative period. Although oncological treatment was performed, the patient died 6 mo after surgery.

CONCLUSION

Squamous cell carcinoma represents a rare disease. Patients often present with large, bulky tumors with involvement of adjacent organs. In spite of progress in surgical techniques and adjuvant chemotherapy, the prognosis remains poor.

Core tip: Pure squamous cell carcinoma represents a very rare condition. Usually the patient will present with a huge mass in the upper right quadrant involving other organs. A high index of suspicion is fundamental for the surgical planning because the surgical removal of the lesion respecting the oncological surgical principles may be the only chance of cure for this aggressive disease. Patients must be submitted to adjuvant chemotherapy in order to increase the survival rates. The prognosis remains poor.
