title: Small cell carcinoma of the esophagus. Report of three cases and review of the literature.
abstract: Small cell carcinoma has been described in the lung, stomach, pancreas, small intestine, larynx, hypopharynx, thymus, kidney, prostate, breast, cervix, skin, and esophagus. Our three cases and review of the literature confirm that the clinical presentation and eventual evolution of small cell carcinomas of the esophagus appear to be basically similar to those of the far more frequently occurring squamous and glandular carcinomas. However, certain differences in age and sex distribution of cases should be noted. Although squamous cell carcinomas occur three to four times more commonly in males, the male-to-female ratio in SCC in 1.6. Squamous cell carcinomas of the esophagus reach a peak in the fifth and sixth decades of life; SCC cases occur a decade later. All of our patients had history of heavy smoking more than 50 pack-years, a factor that has also been implicated in predisposition to squamous cell carcinoma of the esophagus. History of smoking to this extent was also mentioned in three other patients. There are also some differences in the location of the tumor. SCC rarely occurs in the upper third of the esophagus. The most common location of this tumor is the lower third where APUD cells are most abundant. On the other hand, a majority of squamous cell carcinomas of the esophagus are localized to the middle third, the upper and lower third being involved in equal proportions of the cases. Despite the above reported differences in clinical symptoms and course of these two tumors, their gross appearance is similar. Mean survival of both diseases also seems to be similar.(ABSTRACT TRUNCATED AT 250 WORDS)
