“…The pathogenesis of these tumors is poorly understood but may involve squamous de-differentiation of a pre-existing adenocarcinoma or squamous metaplasia progressing to dysplasia and carcinoma as a result of a chronic inflammatory stimulus (1)(2)(3)(4)(5). In the present case, the presence of squamous metaplasia in the adjacent mucosa suggests the latter.…”

Squamous cell carcinoma (SCC) of the colon is a rare tumor that accounts for 0.1%-0.2% of colonic malignancies. However, pure SCC of the cecum is extremely rare. Although SCC of the colon is a rare complication of idiopathic inflammatory bowel disease (IBD), SCC of the cecum in the context of IBD has not been previously reported in the English literature. We report a case of the coexistence of SCC of the cecum and a carcinoid tumor in a 46-year-old female with long-standing pan-ulcerative colitis.

“…It has been described in the literature in about one hundred cases (case reports and series of cases). The first reported case of this kind of colon neoplasm was made in 1919 (2). Later, in 1933, the first primary squamous cell carcinoma of the rectum was described by Raiford (3).…”

Squamous cell carcinoma of the rectum is one of the differential diagnoses of rectal tumors. It represents a low incidence in the population. The etiopathogenesis and the biology of these tumors are unclear, for this reason the gold standard treatment is difficult to establish. We present a 47-years-old woman who had a squamous cell carcinoma in medium rectum. She was treated with radiation therapy and chemotherapy and the treatment was followed by surgical excision.Key words: Rectal cancer. Rectum. Squamous cell carcinoma. Surgery. Radiotherapy. Radiochemotheraphy. INTRODUCTIONSquamous cell carcinoma of the rectum is a rarity within colorectal tumors entity. The incidence of this kind of tumors is estimated at 0.1-0.25 per 1,000 tumors (1). Due to the small number of cases of this disease, the pathogenesis is unclear and it is attributed to different assumptions about the available literature. Although surgery has been considered as the main route of approach, treatment is currently under discussion. CASE REPORTA 47-year-old woman presented with a history of uterine myoma of 10 years evolution and bilateral salpingectomy due to endometriosis. She was studied because of abdominal pain located in lower hemiabdomen, as well as hematochezia and diarrhea, these symptoms accompanied by weight loss during the last month. Physical examination showed a good overall appearance, although a rectal examination revealed a friable mass bleeding to the fingertip friction. The blood test showed hemoglobin levels at the lower limit of normal blood. A colonoscopy showed that the lesion was at 8 cm of the anal verge. It was an exophytic and stenotic tumor with malignant appearance. Biopsies revealed that the rectal mucosa was infiltrated by a squamous cell carcinoma. Immunohistochemistry samples showed CK7 positivity and CK20 negativity with overexpression of p16. HPV 16 was detected by PCR technique. At the cervical cytology and the biopsy by uterine curettage no pathological findings were identified. The computed tomography (CT) showed an irregular mass in the middle rectum as well as lymph nodes in the mesorectal fat with pathological appearance and other smaller unspecified periaortic nodes (Fig. 1). The magnetic resonance imaging revealed a bulky mass of 8 cm in length in the middle rectum with infiltrative appearance which invaded the mesorectal fat and fornix vaginal without cleavage plane (T4CRM+N+) (Fig. 2). The case was discussed by a multidisciplinary committee in our center that decided to perform neoadjuvant chemotherapy with cisplatin and neoadjuvant radiotherapy. After 4 months of treatment, the revaluation clinical tests showed a poor response and surgery was planned. The patient underwent a posterior pelvic exenteration with pelvic peritonectomy and intraoperative radiotherapy. The postoperative histopathological findings were a squamous cell carcinoma of rectum moderately differentiated infiltrating the radial margin pT3N1. Immunohistochemistry tests revealed positivity for AE1, AE3, CK7 and overexpressio...

“…Pure squamous cell carcinoma (SCC) is a histologic subtype of tumors of epithelial origin that is not uncommon in glandular organs such as lung and pancreas, but accounts for only 0.1 to 0.25 cases per 1,000 colorectal carcinomas [2][3][4][5]. After the first case report in 1919 [6], a total of 74 pure SCC of the colorectum and 147 of mixed squamous and adenosquamous cancer cases have been reported in the literature [5,[7][8][9].…”

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.
