XXXX : pitfalls in diagnosis.

@entity1 @entity5 @entity189 @entity3
@entity189 and adnexa commonly simulates other entities both clinically and pathologically. Between 1905 and 1981, 43 @entity1 with sebaceous @entity189 were seen at the Mayo Clinic. Prior to establishing the diagnosis of @entity189 , @entity1 commonly carried multiple clinical diagnoses (mean = 2.2) and multiple microscopic diagnosis (mean = 1.7). The most common clinical diagnosis was chalazion. The @entity1 ' average age at the onset of symptoms was 61.5, with females predominating. The upper eyelid was most commonly involved. The conjunctival surface was involved alone in a statistically greater number of @entity1 with @entity3 (P less than 0.05). Second @entity5 and/or radiation exposure was found in 11 @entity1 , or 25% of our series. Of the second @entity5 , @entity5 of the skin and breast were most common. @entity189 should be suspect in atypical presentations of common disorders and in cases in which clinical and pathologic findings are not well correlated. If sebaceous @entity189 is a diagnostic consideration, we recommend a frozen section with fat stain together with a full-thickness lid biopsy. Surveillance for second @entity5 may be warranted.
