Epithelial remnants of isthmus-catagen cysts.
The histopathologic diagnosis of isthmus-catagen cysts is typically rendered with ease at scanning magnification. Episodically, diagnostic problems may arise when the outermost epithelial portion of the cyst wall separates from the remainder of the cyst. If a histopathologist is unaware of this phenomenon, the findings may be misinterpreted.
