“…6,8 Some reports have emphasized that the squamous carcinoma component metastasizes more frequently and has a more aggressive behavior than that of glandular metastasis. 13,14 Likewise in our case, the survival after operation was only 14 months. Although the behavior of colorectal adenosquamous carcinoma is aggressive, the mechanism of occurrence for this neoplasm has yet to be sufficiently explained.…”

A case of adenosquamous carcinoma of the sigmoid colon is presented herein. An 85-year-old woman without any symptoms was admitted to our hospital to undergo detailed examinations of the colon and rectum. Colonoscopy showed a huge type 2 tumor in the sigmoid colon. A typical sigmoid colectomy and lymph node dissection were performed. A histopathological investigation demonstrated adenosquamous carcinoma invading the subserosa. Although an absolute curative resection was performed, she died of metastatic lung carcinoma 14 months after the operation.

“…The squamous cell component has been reported to have a greater metastatic potential than the glandular cell component, and it has also been detected at metastatic sites. 6 The metastatic lymph nodes in our case contained squamous cells (Fig. 2c).…”

Adenosquamous carcinoma of the sigmoid colon treated by the less invasive procedures of endoscopy and laparoscopy: Report of a case

et al. 2009

A 51-year-old man demonstrated a positive finding for a fecal occult blood test during a screening examination. Total colonoscopy was therefore performed, and a semi-pedunculated polyp was detected in the sigmoid colon. Although this polyp was suspected of invading the submucosal layer, it was removed endoscopically because the preoperative diagnosis was well-differentiated adenocarcinoma. The pathological findings revealed adenosquamous carcinoma that had invaded the submucosal layer with lymphatic invasion. A laparoscopic bowel resection was then performed and a histopathological examination of the surgical specimen showed metastasis to two regional lymph nodes. The patient is alive and recurrence-free 22 months after the operation. Adenosquamous carcinoma has been reported to be rare and to possess a highly metastatic potential. It consists of both squamous cells and glandular cell components. We report a case of adenosquamous carcinoma of the sigmoid colon treated by less invasive approaches consisting of an endoscopic mucosal resection and a subsequent laparoscopic colectomy.

“…As regards the basaloid variety of squamous cell carcinoma outside the anal canal, it may arise from cloaco- genic embryologic nests, squamous metaplastic epithelium, or totipotential basal cells [12]. In mixed adenosquamous variety, Cerezo and others suggested that all such lesions be carefully evaluated by means of immunoperoxidase stains and/or electron microscopy in order to identify squamous features [20,21]. Symptoms, investigations, and assessment of patients with the divergent histologic subtypes of squamous cancer of the colon and rectum, including basaloid tumors, are similar to those of colon adenocarcinoma, as is evident in our case [5,22].…”

We report a case of a 33-year old woman with a squamous-cell carcinoma of the rectum, of the basaloid subtype, infiltrating the uterus. The pathologic data and imaging findings that document the presence of the primary tumor of the rectum are presented in detail. Basaloid tumor is a histologic subtype of squamous-cell carcinoma arising usually in the anal canal. In this article we present a case of basaloid carcinoma of the rectum outside the anal canal with a bibliographical review of this rare clinical entity.
