Colorectal cancer is not just one type of cancer. Differences in outcome and reaction to treatment can at least be partly explained by different histological and molecular subtypes. Recognition of these differences may influence treatment decisions. However, there is huge variation in the amount of information that is available. Several tumour types such as mucinous carcinoma, signet ring cell ...

Primary urethral carcinoma is much more common in women than in men due to its association with urethritis. A 65-year-old man presented with a 10-month history of penile induration, obstructive voiding symptoms and hematuria. Urethrocystoscopy showed a solitary mass in the proximal urethra and no bladder involvement. It was performed penectomy without bladder neck excision and regional staging ...

Objective: To analyze and compare clinico-pathologic characteristics and survival between lung tumors with mixed histologic pattern and our population of resected lung tumors with single histology in the same period. Methods: From January 1993 to December 1999, 1158 patients received resection for lung tumors. Of these, 59 (5.1%) presented a mixed histologic pattern on the surgical specimen. Th...

Brainstem metastases have a poor prognosis and are difficult to manage. The present study describes the first case of histopathologically-confirmed brainstem metastasis originating from lung adenosquamous carcinoma, and discusses the outcomes of treatment by stereotactic aspiration combined with gamma knife radiosurgery (GKRS). A 59-year-old female presented with a cystic mass (15×12×13 mm; vol...

This case report describes an unusual paraneoplastic leukemoid response presenting in a rare instance of gallbladder (GB) adenosquamous carcinoma (ASC). Adenocarcinoma is the most prevalent histological subtype GB carcinoma, which frequently diagnosed people their sixth and seventh decades life. Adenosquamous squamous variations are uncommon. Rarely have reports reaction (PLR) been made; this c...

A 76-year-old Caucasian woman presented with a caruncle tumour, histologically diagnosed as mixed adenosquamous carcinoma. Complete excision was performed, but this necessitated removing parts of the lacrimal canaliculi. No local recurrence or distant metastasis was found after six months' follow-up, and spontaneous recanalisation of both canaliculi occurred. This tumour is believed to be a pri...

Tumor-to-tumor metastasis is extremely rare in the thyroid glands, and only seven cases of lung carcinoma metastasizing to thyroid tumors have been reported in the literature. We report another two cases of lung carcinoma metastasizing to thyroid neoplasms and review of the literature. The first case was a 64-year-old man presenting with neck mass, hoarseness, and easy choking for 2 months. Ima...

A 45 year old man presented with abdominal pain, loss of appetite, and significant weight loss over a period of about four weeks. Imaging of the abdomen showed a mass in the region of the head of the pancreas. In view of the size of the mass and the clinical picture, a Whipple's procedure was performed. Histological evaluation of the pancreatic tumour showed an adenosquamous carcinoma (predomin...

Introduction: Although cervical carcinoma is common, cutaneous metastasis from this tumor is rare. The reported incidence rates of skin metastasis from cervical cancer range from 0.1% to 1.3%. The major histological subtype of cervical carcinoma is squamous cell carcinoma (SCC), accounting for 75% of cases. The remainder are classified as adenocarcinoma, adenosquamous cell carcinoma, or are of ...

Note: Tumor staging is separated by TNM classification (International Classification of Diseases, ICD). TNM classifications for carcinomas of the gallbladder, extrahepatic bile ducts and the ampulla of Vater. The histopathological classification of biliary tract carcinoma follows WHO classification: adenocarcinoma, adenosquamous carcinoma, squamous cell carcinoma, small cell carcinoma, adenoend...
