The histologic diagnosis of adenocarcinoma in situ must consider multiple anatomical and architectural patterns and cytologic features.
In both trials, polymerase chain reaction was used to identify the HPV subtype associated with any CIN, adenocarcinoma in situ, or anogenital lesion that was biopsy-proven, and this information was correlated with the patient's HPV status before and after vaccination.

Adenocarcinoma in situ and minimally invasive adenocarcinomas are of special interest because of their 100% and near 100% 5-year survival, respectively, if completely resected.
Adenocarcinoma in situ is typically located at the transformation zone, although it may be present high up in the endocervical canal (between 20 and 30 mm, measured from the maximal convexity of the portio vaginalis).
Repeat CT scan after 3 months revealed growth of the lesion, and a transthoracic needle biopsy was performed, from which a diagnosis of nonmucinous adenocarcinoma in situ (AIS, formerly bronchioloalveolar carcinoma (2)) was made.
This is a case that performed poorly: of the 88 participants in this case, 28% called it abnormal (18% adenocarcinoma, 5% adenocarcinoma in situ, and 5% highgrade intraepithelial lesion/carcinoma).
Distribution of preceding Papanicolaou (Pap) test diagnoses divided into ''low-grade'' (atypical squamous cells of undetermined significance [ASC-US] and low-grade squamous intraepithelial lesion [LSIL]) and ''high-grade'' (low-grade squamous intraepithelial lesion, a highgrade squamous intraepithelial lesion cannot be ruled out [LSIL-H]; atypical squamous cells, a high-grade squamous intraepithelial lesion cannot be ruled out [ASC-H]; high-grade squamous intraepithelial lesions [HSIL]; atypical glandular cells [AGC]; adenocarcinoma in situ [AIS]; squamous cell carcinoma).
