149 patients aged 30-80 years (76 males, 73 females) underwent a surgical treatment of basocell skin carcinoma in the period of 1992-1996. Results showed that: this carcinoma was common on the elderly, mainly on the skin area of face and neck, especially the areas of nose, cheek and eyes. A high rate of patients admitted in hospital early. After operation, the rate of recurrent accounted for 16.8%, the most occurred within 2 years after, especially of the tumors of > 5 cm. The recurrent tumors  2cm occurred only within the first 2 years, and later for the larger tumors.

Papillary thyroid microcarcinoma (PTMC) is defined as a papillary thyroid carcinoma measuring less than 10 mm in diameter. With the development of ultrasonic technology and the popularization of physical examination, the incidence of PTMC increased dramatically. Routine preoperative diagnostic methods include clinical examination, thyroid ultrasound and fine needle aspiration biopsy. But its treatment methods are still controversal. In this paper, we review literatures in recent years and discuss the clinical common problems of PTMC.

Combined hepatocellular-cholangiocarcinoma is a rare form of primary liver cancer showing features of both hepatocellular and biliary epithelial differentiation. We report here on a case with collision tumor, which apparently was the coincidental occurrence of both hepatocellular carcinoma and cholangiocarcinoma underlying schistosomiasis. A 39-year-old-Philippine female was transferred to our hospital for evaluation of a liver mass that was found on ultrasonography at a local hospital. HBsAg and Anti-HCV were negative and serum alpha-fetoprotein (AFP) level was normal. The tumor mass was histologically diagnosed as adenocarcinoma by sono-guided biopsy before the operation. Partial lobectomy was performed and we histologically identified the concurrent occurrence of hepatocellular carcinoma and cholangiocarcinoma, (a "collision type carcinoma").

OBJECTIVE: To investigate the clinical, pathological character and differential diagnosis of laryngeal verrucous carcinoma. METHOD: Clinical data of one case with laryngeal verrucous carcinoma in our hospital were retrospectively analyzed. RESULT: The diagnosis of verrucous carcinoma was difficult and depend on repeated biopsy. Verrucous carcinoma of larynx is a highly differentiated variant of squamous carcinoma that has peculiar clinical and morphological features. The basement membrane is not invaded. It is prone to distant metastasis, than to local recurrence. The case underwent the partial laryngectomy, and was followed up for more than 4 years with no recurrence. CONCLUSION Verrucous carcinoma of the larynx is a special pattern of the well-differentiated squamous cancer. A correct diagnosis requires close cooperation between the laryngologist and the pathologist. The main treatment of verrucous carcinoma is complete surgical excision to reserve larynx function as far as possible and improve the quality of life.
