NEOPLASMS OF UNCERTAIN BEHAVIOR (235-238)

Neoplasm of uncertain behavior of digestive and respiratory systems
Neoplasm of uncertain behavior of genitourinary organs
Neoplasm of uncertain behavior of endocrine glands and nervous system
Neoplasm of uncertain behavior of other and unspecified sites and tissues

Note: Categories 235-238 classify by site certain histo-morphologically well-defined neoplasms, the subsequent behavior of which cannot be predicted from the present appearance.
