An adenosquamous carcinoma is a malignancy that has both glandular and squamous histologic components. Both components are malignant and have potential to metastasize. An adenosquamous carcinoma of the large bowel is rare, and its clinicopathologic behavior is not fully understood. It is reported to be more aggressive and have a worse prognosis when it is compared with an adenocarcinoma alone. ...

adenosquamous carcinomas of stomach are rare entities comprising 0.5% of stomach carcinomas. here, we report a case of a 50-year-old female, who presented with weakness, pallor, and symptoms of gastric outlet obstruction. a partial gastrectomy was done and histology showed evidence of adenosquamous carcinoma of the antrum with metastasis to the perigastric lymph nodes. the patient condition imp...

Lung adenosquamous carcinoma is a particular subtype of non-small cell lung carcinoma that is defined by the coexistence of adenocarcinoma and squamous cell carcinoma components. The aim of this study was to assess the mutational profile in each component of 16 adenosquamous carcinoma samples from a Caucasian population by a combination of next generation sequencing using the cancer hotspot pan...

Primary urinary bladder adenosquamous carcinoma is extremely rare and only a few cases have been reported in English literatures. Its biological behavior remains unclear. Here we reported a 60-year-old male patient with lower limb deep venous thromboses associated with primary urinary bladder adenosquamous carcinoma. A color ultrasonography showed right stock total venous thrombosis and right g...

Formalin-fixed, paraffin-embedded tissues from 108 cases of invasive carcinoma of the uterine cervix, consisting of 40 cases of adenocarcinoma, 44 cases of adenosquamous carcinoma, and, as a control, 24 cases of squamous cell carcinoma were examined for the presence of human papillomavirus (HPV) DNA by in situ hybridization of high sensitivity using tritium-labeled HPV-2, HPV-6, HPV-16, and HPV...

Adenosquamous carcinoma is defined as a tumor in which both glandular and squamous elements are histologically malignant. Although some published studies have analyzed and discussed adenosquamous carcinomas, hybrid malignancy of the ampulla of Vater has rarely been discussed thus far in the literature. In this study, we report the case of a 64-year-old man who presented with jaundice and interm...

BACKGROUND Among the numerous human papillomavirus (HPV) types, only types 16 and 18 have been formally classified as human carcinogens. To evaluate the associations of 33 HPV types and other risk factors with squamous cell carcinoma and adenocarcinoma of the cervix, we performed a hospital-based, case-control study in the Philippines. METHODS The study included 356 case subjects who had hist...

Adenosquamous carcinoma of the head and neck (ASC) is a rare and aggressive variant of squamous cell carcinoma, a locally aggressive malignancy characterized by the presence of two distinct components: a squamous cell carcinoma and an adenocarcinoma. The purpose of this study was to report an additional rare case of adenosquamous carcinoma affecting the maxilla, with clinical microscopic featur...
