Carcinome épidermoïde primitif du colon: à propos d’un cas

Abstract

Le carcinome épidermoïde (CE) primitif du côlon est une tumeur exceptionnelle. Moins de 150 cas ont été publiés dans la littérature jusqu'à l'année 2014. Outre sa rareté, il se distingue par son association fréquente avec d'autres néoplasies digestifs. Nous rapportons l'observation d'un patient de 54 ans ayant une CE primitive du côlon. À la lumière de cette observation, on discutera les particularités anatomo-cliniques et thérapeutiques ainsi que les hypothèses étiopathogéniques de cette entité peu commune.

Mixed neuroendocrine and squamous cell carcinoma of the colon: A case report and literature review

“…Tumors are often identified by colonoscopy. Similarly, symptoms of SCC of the colon have been clinically compared to that of adenocarcinoma [9], which includes constipation, rectal bleeding, and abdominal pain. Our patient showed symptoms of abdominal pain and constipation.…”

Primary Squamous Cell Carcinoma of the Descending Colon

“…Schmidtman published the first report of a pure SCC of the colon in 1919 [6]. Since then, less than 150 cases have appeared in the literature [7]. Most pure SCC cases of the colon have been reported in the rectosigmoid colon, where as our case it was in the descending colon.…”

“…Assessing the prognosis of patients with colorectal SCC is challenging due to its rarity. Certain factors would be associated with a poor prognosis such as the ulcerated nature of the lesion, the left localization of the tumor, lymph nodes metastasis, stage IV of TNM, and the degree of differentiation of the tumor (poorly differentiated and undifferentiated) [7].…”

Primary Cecal Squamous Cell Carcinoma: A Case Report of a Rare Tumor with Poor Prognosis

“…However, SCC is more aggressive and can be discovered with some complications: peritonitis due to perforated tumor (like our case), bowel obstruction, or metastases. Some criteria are necessary to retain the diagnosis of a pure colonic SCC: absence of other locations of squamous cell carcinoma that may cause colonic invasion or metastasis, histological analysis must also rule out an adenosquamous colonic tumor associating glandular and squamous contingents [10].…”
